QJ系列油浸式变压器用气体继电器安装使用说明书沈阳隆辉电器有限公司1、概述1.1产品用途QJ 系列气体继电器(以下简称继电器),是油浸式变压器所用的一种保护装置,继电器安装在变压器与储油柜的连接管路上,在变压器运行中由于内部故障而使油分解产生气体造成油流涌动时,使继电器的接点动作,接通指定的控制回路,并及时发出报警信号或切除信号,从而达到保护变压器的目的。
1.2型号组成及其含义注:特殊使用环境代号TH-湿热带型 TA-干热带型 一般型不加表示 1.3使用条件:允许工作温度:-30℃ ~ +95℃2、结构与工作原理2.1气体继电器结构1. 探针 6. 接线端子2. 气塞 7. 上盖3. 重锤 8. 弹簧4. 浮子 9. 干簧接点5. 磁铁 10. 挡板图1 继电器芯子结构2.2气体继电器工作原理变压器正常工作时,继电器内是充满变压器油的,当变压器在运行中出现轻微故障时,因变压器油分解而产生的气体将积聚在继电器容器的上部,迫使继电器油面下降,浮子随之下降至某一限定位置时,磁铁使信号接点接通,发出报警信号。
若因变压器漏油而使油面降低,同样发出报警信号。
当变压器内部发生严重故障时,油箱内压力瞬时升高,将会出现油的涌浪,从而在管路内产生油流,冲击继电器的挡板运动。
当挡板运行到某一限定位置时,磁铁使跳闸接点接通,将变压器从电网中切除。

根据工作特性可分为常开型和常闭型。
3.2 固态继电器固态继电器采用固态器件(如半导体器件)实现电路的控制和隔离。
与传统的电磁式继电器相比,固态继电器具有响应快、寿命长、可靠性高等特点。
3.3 保护继电器保护继电器主要用于电力系统中的故障保护,能够侦测电流、电压等参数,并在异常情况下及时切断电路以保护设备和人员的安全。
4. 继电器的使用方法4.1 连接方式继电器通常需要与外部电路配合使用。
在使用继电器时,需要按照电气图纸中的接线方式进行连接,确保线路的正确性和稳定性。
4.2 控制信号继电器的线圈需要接收控制信号才能工作。

如发现异常,应及时处理或更换继电器。
6. 总结继电器作为一种重要的电气开关装置,在自动化控制系统中扮演着重要角色。
常用继电器使用说明继电器是一种根据输入信号的变化,接通或断开小电流电路,以实现自动控制和保护功能的电器。
继电器的分类方法很多,按输入信号的性质可分为:电压继电器、电流继电器、速度继电器、压力继电器等;按工作原理可分为:电磁式继电器、电动式继电器、感应式继电器、晶体管式继电器和热继电器等;按输出方式可分为:有触点式和无触点式。
继电器主要由感测机构、中间机构和执行机构3部分组成。
1.中间继电器中间继电器是用来增加控制电路中的信号数量或将信号放大的继电器。
其输入信号是线圈的通电和断电,输出信号是触头的动作,由于触头的数量较多,所以可以用来控制多个元件或回路。
JZ系列中间继电器的外形如图所示。
(1)结构中间继电器由线圈、静铁心、动铁心、触头系统、反作用弹簧及复位弹簧等组成。
JZ7型中间继电器的结构如图所示。
(2)选用中间继电器主要根据被控制电路的电压等级、所需触头的数量、种类、容量等要求来选择。
(3)安装与使用中间继电器的使用与接触器相似,但中间继电器的触头容量较少,一般不能在主电路中应用。
中间继电器一般根据负载电流的类型、电压等级和触头数量来选择。
2.热继电器热继电器一般作为交流电动机的过载保护用,热继电器有两相结构、三相结构和三相带断相保护装置等3种类型。
JR系列热继电器的外形如图所示。
(1)结构它是由热元件、触头系统、动作机构、复位机构和整流电流装置组成。
其结构如图所示。
(2)工作原理使用时,将热继电器的三相热元件分别串接在电动机的三相主电路中,常闭触头串接在控制电路的接触器线圈回路中。
当电动机过载时,流过电阻丝的电流超过热继电器的整定电流,电阻丝发热,主双金属片向右弯曲,推动导板向右移动,通过温度补偿双金属片推动推杆绕轴转动,从而推动触头系统动作,动触头与常闭静触头分开,使接触器线圈断电,接触器触头断开,将电源切除起保护作用。
电源切除后,主双金属片逐渐冷却恢复原位,于是动触头在失去作用力的情况下,靠弹簧的弹性自动复位。

56圈电阻)继电器即可以动作,但此时并不保险,其中驱动电压和电阻的变化以及温升等因素都可能使已吸合的继电器释放或不稳定。
因此,要保证继电器可靠工作,就必须使线圈中的电流值为吸合电流的1.5~2倍,而且,受环境温度或线圈自身温升的影响,线圈电阻大致以0.4%/︒C 的比例变化,这可能会使吸合电压和释放电压发生变化;如果温度升高,则吸合电压和释放电压会相应增大,对于这一点应特别注意。

用户使用时应注意以下各项1、线圈使用电压线圈使用电压在设计上最好按额定电压选择,若不能,可参考温升曲线选择。
使用任何小于额定工作电压的线圈电压,将会继续影响继电器工作,注意线圈工作电压是指加到线圈引出端之间的电压,特别是用放大电路来激励线圈,务必保证线圈两个引出端的电压值,反之超过最高额定工作电压时也会影响产品性能,过高的工作电压会使线圈温升过高,特别是在高温下,温升过高会使绝缘材料受到损伤,也会影响到继电器的工作安全,对磁保持继电器,激励(或复归)脉宽不小于吸合(或复归)时间的3倍,否则产品会处于中位状态。
用固态器件来激励线圈时,其器件耐压至少在80V以上,且漏电流要足够小,以确保继电器的释放。
2、瞬态抑制继电器线圈断电瞬间,线圈上可产生高于线圈额定工作电压值30倍以上的反峰电压,对电子线路有极大的危害,通常采用并联瞬态抑制(又叫削峰)二极管或电阻的方法加以抑制,使反峰电压不超过50V,但并联二极管会延长继电器的释放时间3-5倍,当释放时间要求高时,可在二极管一端接一个合适的电阻。
3、多个继电器的并联和串联供电多个继电器并联供电时,反峰电压高(即电感大)的继电器会向反峰电压低的继电器放电,其释放时间会延长,因此最好每个继电器分别控制后再并联才能消除相互影响,不同线圈电阻和功耗的继电器不要串联供电使用,否则串联回路中线圈电流大的继电器不能可靠工作,只有同规格型号的继电器可以串联供电,但反峰电压会提高,应予以抑制,可以按分压比串联电阻来承受供电电压亮出继电器的线圈额定电压的那部分电压。
4、触点负载加到触点上的负载应符合触点的额定负载和性质,不按额定负载大小(或范围)和性质施加负载往往容易出现问题,只适合直流负载的产品不应用于交流场合。

第一节继电器原理知识一、继电器的定义继电器是一种当输入量(电、磁、声、光、热)达到一定值时,输出量将发生跳跃式变化的自动控制器件。
继电器是具有隔离功能的自动开关元件,广泛应用于遥控、遥测、通讯、自动控制、机电一体化及电力电子设备中,是最重要的控制元件之一。
....继电器一般都有能反映一定输入变量(如电流、电压、功率、阻抗、频率、温度、压力、速度、光等)的感应机构(输入部分);有能对被控电路实现“通”、“断”控制的执行机构(输出部分);在继电器的输入部分和输出部分之间,还有对输入量进行耦合隔离,功能处理和对输出部分进行驱动的中间机构(驱动部分)。
....作为控制元件,概括起来,继电器有如下几种作用:.....1) 扩大控制范围。
例如,多触点继电器控制信号达到某一定值时,可以按触点组的不同形式,同时换接、开断、接通多路电路。
.....2) 放大。
例如,灵敏型继电器、中间继电器等,用一个很微小的控制量,可以控制很大功率的电路。
.....3) 综合信号。
例如,当多个控制信号按规定的形式输入多绕组继电器时,经过比较综合,达到预定的控制效果。
.... 4) 自动、遥控、监测。
例如,自动装置上的继电器与其他电器一起,可以组成程序控制线路,从而实现自动化运行。
二、继电器的工作原理如图所示,当控制电路中的开关K闭合时,电磁铁便具有磁性,将衔铁吸下,使继电器触点接触,与触点相连接的电源电路便接通;当控制开关K断开时,电磁铁的磁性被撤消,继电器触点弹开,电源电路亦随之断开。
三、继电器的继电特性继电器的输入信号x从零连续增加达到衔铁开始吸合时的动作值x x,继电器的输出信号立刻从y=0跳跃到y=y m,即常开触点从断到通。
一旦触点闭合,输入量x继续增大,输出信号y将不再起变化。
当输入量x从某一大于x x值下降到x f,继电器开始释放,常开触点断开(如图1)。
我们把继电器的这种特性叫做继电特性,也叫继电器的输入-输出特性。

open,closeN/C,N/O表⽰常闭和常开,normal close 、normal openC.O是转换型的,即含有NORMAL OPEN和NORMAL CLOSE两侧个⼈理解(可能不对),触点的电流值是触点接触点的⾯积和触点物质所决定的,⼚商规定电流⼤⼩由此⽽决定,也是根据。
触点所规定的电压,是触点断开所规定电流值时的距离及速度,我们搞电的应该知道,多⼤距离能拉断多⼤的电压,多⼤的断开速度和距离,能断开多⼤的电压。
所以,继电器触点所规定的电流与电压,是根据触点⼤⼩和分断时的速度所决定的。
当然,这电流电压还与交流和直流有关系,我们知道,交流电是每秒钟100次过零点,在电流电压过零点时,断开最容易,所以,断开交流的值可以⾼⼀点,直流相对会低⼀点。
继电器短时间内频繁通断会引起触点融化或者烧结。

Getting startedHow to use this manualThis manual gives step-by-step instructions for safe and correct assembly of the kit and fitting and connecting of the ready-built module, and operation. Before you start, we advise you to read the whole manual, particularly the chapter on safety instructions and the checklist for trouble shooting. You will then know where to take care and how to prevent mistakes which take a lot of effort to correct.Keep this manual safely so that you can solve problems in the future. If you pass the kit or the ready-built module on to another person, please pass on the manual with it.Intended useThe relay circuit board RL-2 is designed to be operated according to the instructions in this manual in model building, especially with model railways. Any other use is inappropriate and invalidates any guarantees.The RL-2 should not be assembled or mounted by children under the age of 14.Reading, understanding and following the instructions in this manual are mandatory for the user.Checking the package contentsPlease make sure that your package contains:▪one kit, containing the components listed in the parts list and one PCB or▪one ready-built module▪ a CD (containing the manual and further information)Page 3t a mse le kt r on ikEnglishRL-2Required materialsFor assembling the kit you need:▪an electronic soldering iron (max. 30 Watt) or a regulated soldering iron with a fine tip and a soldering iron stand,▪ a tip-cleaning sponge,▪ a heat-resistant mat,▪ a small side cutter and wire stripper,▪as necessary a pair of tweezers and long nose pliers,▪electronic tin solder (0,5 mm. diameter).For testing the module you need an electric light bulb.In order to connect the module you need wire. Recommended diameters: > 0,25 mm² for all connections (e.g. item no. 73-1031x,x=0..9).For the connection to the switching inputs you need:▪two push buttons, e.g. item no. 84-5212x, x=1..5 (or circuits to release a switching pulse).Page 4t a mse le kt r on ikRL-2English2. Safety instructionsMechanical hazardsCut wires can have sharp ends and can cause serious injuries. Watch out for sharp edges when you pick up the PCB.Visibly damaged parts can cause unpredictable danger. Do not use damaged parts: recycle and replace them with new ones.Electrical hazards▪Touching powered, live components,▪touching conducting components which are live due to malfunction,▪short circuits and connecting the circuit to another voltage than specified,▪impermissibly high humidity and condensation build upcan cause serious injury due to electrical shock. Take the following precautions to prevent this danger:▪Never perform wiring on a powered module.▪Assembling and mounting the kit should only be done in closed,clean, dry rooms. Beware of humidity.▪Only use low power for this module as described in this manual and only use certified transformers.▪Connect transformers and soldering irons only in approved mains sockets installed by an authorised electrician.▪Observe cable diameter requirements.▪After condensation build up, allow a minimum of 2 hours for dispersion.▪Use only original spare parts if you have to repair the kit or the ready-built module.Page 5mse le kt r on ikEnglish RL-2Fire riskTouching flammable material with a hot soldering iron can cause fire, which can result in injury or death through burns or suffocation. Connect your soldering iron or soldering station only when actually needed. Always keep the soldering iron away from inflammable materials. Use a suitable soldering iron stand. Never leave a hot soldering iron or station unattended.Thermal dangerA hot soldering iron or liquid solder accidentally touching your skin can cause skin burns. As a precaution:▪use a heat-resistant mat during soldering,▪always put the hot soldering iron in the soldering iron stand,▪point the soldering iron tip carefully when soldering, and▪remove liquid solder with a thick wet rag or wet sponge from the soldering tip.Dangerous environmentsA working area that is too small or cramped is unsuitable and can cause accidents, fires and injury. Prevent this by working in a clean, dry room with enough freedom of movement.Other dangersChildren can cause any of the accidents mentioned above because they are inattentive and not responsible enough. Children under the age of 14should not be allowed to work with this kit or the ready-built module.In schools, training centres, clubs and workshops, assembly must be supervised by qualified personnel. In industrial institutions, health and safety regulations applying to electronic work must be adhered to.Page 6t a mse le kt r on iRL-2English3. Safe and correct soldering▪Use a small soldering iron with max. 30 Watt or a regulated soldering iron.▪Only use electronic tin solder with flux.▪When soldering electronic circuits never use soldering-water or soldering grease. They contain acids that can corrode components and copper tracks.▪Insert the component connecting pins into the PCB´s holes as far as possible without force. The components should be close to the PCB`s surface.▪Observe correct polarity orientation of the parts before soldering.▪Solder quickly: holding the iron on the joints longer than necessary can destroy components and can damage copper tracks or soldering eyes.▪Apply the soldering tip to the soldering spot in such a way that the part and the soldering eye are heated at the same time.Simultaneously add solder (not too much). As soon as the solder becomes liquid take it away. Hold the soldering tip at the spot for a few seconds so that the solder flows into the joint, then remove the soldering iron.▪Do not move the component for about 5 seconds after soldering. ▪To make a good soldering joint you must use a clean and unoxidised soldering tip. Clean the soldering tip with a damp piece of cloth, a damp sponge or a piece of silicon cloth.Page 7t a mse le kt r on ikEnglish RL-2▪Cut the wires after soldering directly above the soldering joint with a side cutter.▪After placing the parts, please double check for correct polarity.Check the PCB tracks for solder bridges and short circuits created by accident. This would cause faulty operation or, in the worst case,damage. You can remove excess solder by putting a clean soldering tip on the spot. The solder will become liquid again and flow from the soldering spot to the soldering tip.Page 8t a mse le kt r on ikRL-2English4. Operation overviewThe module switches a bistable relay with two switches which are separate from each other. It is triggered by 12 to 18 Volt direct (d.c.) or alternating (a.c.) voltage. The relay is switched by an earth contact and can be switched by any earth compatible output (e.g. by a points decoder). This enables the module to switch two connected electric loads in joint action. It is possible to connect e.g. a light signal and the block section that it controls.5.

Assembling the kitYou can skip this part if you have purchased a ready-built module.PreparationPut the sorted components in front of you on your workbench. The separate electronic components have the following special features you should take into account in assembling:ResistorsResistors reduce current.The value of resistors for smaller power ratings is indicated through colour rings. Every colour stands for another figure.Carbon film resistors and some types of have 4 colour rings. The 4th ring (given in brackets here) indicates the tolerance of the resistor (gold = 5 %).220 red - red - brown (gold)DiodesDiodes allow the current to pass through in one direction only (forward direction), simultaneously the voltage is reduced by 0,3 to 0,8 V. Exceeding of the limit voltage always will destroy the diode, and allow current to flow in the reverse direction. The diode type is printed on the package.Relays Relays are electronic switches, depending on their position the one or other (internal) connection is closed. The mode of operation of monostable relays can be compared to that of a push-button switch,i.e. the connection is only closed as long as the voltage is applicated.Page 10t a m s e ln i k RL-2English Bistable relays keep their status after switching – comparable to a switch.Relays which combine two switches in one housing are common as well (shortly 2xUM). The switching between the two connections can be heard clearly because of the resulting clicking sound.PCB socketsThe widely spread 2,6 mm model railway connectors fit exactly to the sockets. These are used for the connection to the voltage supply and to connected modules or components.Fig. 1: PCB layoutPage 11t a m s e l e k t r EnglishRL-2Assembly Proceed according to the order given in the list below. First solder the components on the solder side of the PCB and then cut the excess wires with the side cutter. Follow the instructions on soldering in section 3.1.PCB sockets 2.Resistors Mounting orientation of no importance. 3.DiodesObserve the polarity!The negative end of the diodes is marked with a ring. This is shown in the PCB layout.4.Relays The mounting orientation is given by the layout of the pins. Performing a visual check Perform a visual check after the assembly of the module and remove faults if necessary: ▪Remove all loose parts, wire ends or drops of solder from the PCB.Remove all sharp wire ends. ▪Check that solder contacts which are close to each other are not unintentionally connected to each other. Risk of short circuit!▪Check that all components are polarised correctly.When you have remedied all faults, go on to the next part.Page 12RL-2English7. Performing a functional testYou can perform a functional test with an electric light bulb before mounting the relay circuit board. First connect the relay circuit board and the light bulb as follows:Then perform the following tests:After a successful test, disconnect the power supply and the lamp from the module. Mount the module as desired in your model railroad.Page 13k English RL-28. Connecting the relay circuit boardConnecting the power supplyIf you use a d.c. transformer for the power supply of the relay circuit board, you have to regard the polarity when connecting it, if using an a.c. transformer the polarity is of no importance. If you supply several components by one a.c. transformer you have to be careful to connect Page 14t a m se l e k t r o n i k RL-2English Fig. 2: Connections It shows as an example, the connection of the relay circuit board to a double purpose light signal.

QJ系列气体继电器(以下简称继电器),是油浸式变压器所用的一种保护装置,在变压器运行中由于内部故障而使油分解产生气体或造成油流涌动时,使继电器的接点动作,以接通指定的控制回路,并及时发出报警信号或切除信号,从而达到保护变压器的目的。
二、工作原理
变压器正常工作时,继电器内是充满变压器油的,当变压器在运行中出现轻微故障时,因变压器油分解而产生的气体将积聚在继电器容器的上部,迫使继电器浮子下降,当浮子降至某一限定位置时,磁铁使信号接点接通,发出报警信号。
若因变压器漏油而使油面降低,同样发出报警信号。
当变压器内部发生严重故障时,油箱内压力瞬时升高,将会出现油的涌浪,从而在管路内产生油流,冲击继电器的挡板运动。
当挡板运行到某一限定位置时,磁铁使跳闸接点接通,将变压器从电网中切除。

1、Application
The Gas relay series QJ is protective device for oil immered transformer.If a fault causesgas to be generated in the transformer or a heavy surge of insulating oil the Gas relay shall be in operation,the alarm signal is initeated and/or the transformer is tripped automatically.
2、Pirnciple of design
When the transformer is operating normally,the Gasrelay is completely filled with insulating oil .If a fault causes ges to be generrated in the transformer,the bubble will filter along towards the conservator and accumulated at the highest point in the Gas relay.As the amount of gas couecte increses and the oil level in relay fall as a result,the cupalso falls and eventually reaches point where it actuates the magnetic switch with the permanent magnet and soinitiated the alarm signal.If the oil loses,the alarm signalis slso initiated A violent generation of gas accompanied by a heavy surge of insulating oil results in operation of baffle plate.the magnetic is actuated by the permantmagnet on the baffle plate so it trips the transformer.
