KPFK系列低压电容投切复合开关使用说明书南京卡鹏科技有限公司1、概述采用传统的交流接触器投切电容器的冲击电流大，影响电容器和接触器的使用寿命；而用晶闸管投切电容器能解决接触器投切电容器存在的问题，但明显缺点是装置存晶闸管功率损耗，需要安装风扇和散热器来通风与散热，而散热器不但会增大装置的体积，而且风扇的工作与否则将直接影响无功补偿装置的可靠性。
为解决这些问题，我们采用可控硅复合开关为投切元件的无功补偿装置，装置采用单相与三相复合式补偿的方式，装置能实现三相补偿同时又能进行单相补偿，以满足三相不平衡系统的需要。
KPFK系列可控硅复合式开关是本公司结合多年可控硅（晶闸管）在无功补偿技术领域应用的经验，研制而成的一种新型智能型可控硅复合开关(可控硅+磁保持继电器技术)。
KPFK系列复合式开关普遍适用于各种交流接触器、晶闸管（可控硅）、固态继电器应用场合。
该开关器件具有在其开关动作时无触点拉弧、无冲击电流现象,而且工作时功耗低、无需加装散热装置的特点，特别适用于交流电机启动、感性、容性或电阻负载的投切。
KPFK系列复合式开关与目前市场普遍用于电容器投切的复合开关最重要的区别在于启动控制技术的应用。
该项技术主要是指交流负载启动时复合开关能控制使电流在短时间内从0稳步上升到额定工作电流。
KPFK系列低压复合开关工作原理是：将可控硅与磁保持继电器并联接通电路。
可控硅在投入和切除的瞬间进行过零投切，即电压过零时刻投入，电流过零时刻切除，可控硅短时间导通后，转为磁保持继电器接通运行。
因此，它既具有可控硅开关过零投切无涌流的优点，又具有机械触点运行无功耗的长处，也就避免了可控硅运行发热和机械触点投切火花的缺陷，是一种较为理想的投切开关。
由于磁保持继电器在吸合与断开的瞬间都没有涌流和火花，因此，它的电器寿命远高于设计的寿命，而它的机械寿命高达百万次，可以保证长期运行。
2.主要特点：电压/电流过零点导通与分断；开关时无冲击电流、功耗低，无需加装任何散热装置；开关时无触点拉弧现象，无谐波污染，具备失压掉电自保护功能；采用光耦隔离技术，具有较强的抗干扰能力；性能稳定，使用可靠，免维护周期长；结构简单，接线方便。
FK系列智能复合开关产品使用说明书1. 产品简介FK系列智能复合开关（简称复合开关）有共补开关(FK300)和分补开关(FK100)两种，共补开关用于投切三相电容，即三角型接法的电容；分补开关用于投切单相电容，即分别接三只单相电容的一端，三只单相电容的另一端接零线。
复合开关选用晶闸管开关和磁保持开关并联运行，其在接通和断开的瞬间具有可控硅过零投切的优点，而在正常接通期间又具有磁保持开关零功耗的优点。
复合开关具有无冲击、低功耗、高寿命等显着优点，可替代接触器或晶闸管开关，广泛用于低压无功补偿领域。
该产品通过了电力工业电力设备及仪表质量检验测试中心的检验。
2. 功能特点☆电压过零投入，电流过零切断；☆开关接通后低功耗，不用外加散热片；☆无需外接串联电抗器；☆输入信号与开关光电隔离；☆可直接与无功补偿控制器配合使用；☆内置控制电源，无需外配电源；☆具有开关状态指示灯，电容接通时，指示灯亮；☆抗干扰能力强，高EMC保护措施；3. 技术参数3.1 主电路3.2 控制电路3.3 电磁兼容3.4 工作条件①：除火灾、爆炸、水淹、强化学腐蚀等场所外的地方。

1.0 Description (3)2.0 Application (3)3.0 Operation (3)4.0 Mounting & Installation ..................................................................................................................................... (4)5.0 Warranty Statement (5)6.0 RMA Form (6)1.0 DescriptionThe K-TEK PS45 is a point level (on - off) pneumatic switch device used in conjunction with the K-TEK KM26 Mag-netic Liquid Level Gauge (MLG), LS Series Mechanical Cage Level switch or an External Chamber. The unique magnetic coupling action eliminates the need for such things as seals, diaphragms, springs or torque tubes. Since process connections to the switch are eliminated, the user is insured complete isolation from the process. Valves are not required to block off the switch from the process for maintenance or operational testing. Preventive mainte-nance functions are greatly reduced since the switch never contacts the process fluid.2.0 ApplicationThe PS45 is designed to provide a provide a pneumatic control signal dependent on the liquid level within a vessel. The device is configurable such that actuation can occur on rising and falling level. When a magnetic float passes in the first direction, the PS45 will route the input supply gas through to its output port. When the float passes in the opposite direction, the supply gas is shut off (disconnected) from the output port and the output port typically vented to the atmosphere. The PS45 thus provides the user with a pneumatic signal that can be used to activate alarms and/or open and close control valves. An example application would be the pneumatic operation of safety shutdown systems on oil and gas production equipment.3.0 OperationThe PS45 switch mechanism consists of the following integral components:1. Actuating cam-spindle-magnet assembly2. Precision Micropilot™ valve assembly3. User connections.As the magnetic float travels past the switch, the cam-spindle-magnet assembly actuates the Micropilot™ valve as-sembly. The switch will then provide for a path for the supply gas to travel between ports A-C or B-C, depending on the position of the float relative to the switch (see Figure 1). A continuous gas supply is not required for normal op-eration since the PS45 is not a pilot operated device. The PS45 is easily configured in the field as direct or reverseacting by simply changing the field connections at ports A & B. All user connections are 1/8 inch FNPT.4.0 Mounting & InstallationThe simplicity of mounting the PS45 switch housing is such that the only necessary tool is a small screwdriver. The switch is attached to the KM26 via two small stainless steel variable clamps. These clamps allow the switch to be positioned anywhere over the entire length of the float chamber, thereby providing an infinitely variable trip point set-ting. Loosening the clamps will allow the PS45 to be easily moved to provide a new trip point. Other switches can be added at any time without the concern for additional process piping or valves.PS45 Mounted on KM26 Magnetic Level GaugePS45 Mounted on LS Series Mechanical Level Switchdetermine how the option filter and vent fitting are supplied from the factory. The filter and vent fitting are easily changed in the field.

在使用该产品之前，请认真阅读本说明书，并予以妥善保管。
复合开关只有在正确地接线并与相应的电容容量配置后，才能正确可靠地使用。
安全性1）该复合开关的安装、维护和操作需由具有相关专业知识和技能的人员进行。
2）确定电源供电系统是0.4KV的系统，复合开关不可用于高于0.4KV 的供电系统3）确保该复合开关的工作电压（内部的相线已连接，外部接入零线N端）在AC220V±20%、50HZ±10%范围内。
4）不要随意打开复合开关的外壳，以防触电。
工作原理SFK系列低压复合开关基本工作原理是：将可控硅与磁保持继电器并联。
由内部的单片机控制，在投入和切除的瞬间由可控硅承担过零投切，即电压过零时刻投入，电流过零时刻切除，可控硅导通时间很短（不产生发热），之后，转换为磁保持继电器接通运行。
因此，它具有可控硅TSC开关过零投切无涌流的优点，又具有交流接触器运行无功耗的长处。
也就又避免了可控硅运行发热和接触器投切火花的缺陷。
是一种较为理想的投切开关。
特别是，由于磁保持继电器在吸合与断开的瞬间都没有涌流和火花，因此，它的电器寿命远高于设计的寿命，而它的机械寿命高达百万次，可以保证长期运行。

主要优点是接到外部控制信号后，通过复合开关内部的控制电路，自动寻找最佳投入（切除）点；保证过零投切，无涌流、触点不烧结、能耗小、无谐波注入，同时具有电压异常保护、运行指示等功能。
