空气断路器,就是空气开关,在电路中作接通、分断和承载额定工作电流,并能在线路和电动机发生过载、短路、欠压的情况下进行可靠的保护。
断路器的动、静触头及触杆设计成平行状,利用短路产生的电动斥力使动、静触头断开,分断能力高,限流特性强。
电力、自动化领域的领导厂商ABB旗下的空气断路器- Emax 2 (新E型)凭借优异性能备受青睐。
●短路时,静触头周围的芳香族绝缘物气化,起冷却灭弧作用,飞弧距离为零。
断路器的灭弧室采用金属栅片结构,触头系统具有斥力限流机构,因此,断路器具有很高的分断能力和限流能力。
●具有复式脱扣器。
反时限动作是双金属片受热弯曲使脱扣器动作,瞬时动作是铁芯街铁机构带动脱扣器动作。
脱扣方式有热动、电磁和复式脱扣3种。
空气开关内部比较复杂,原理却甚为简单。
它在入线和出线间串了个十几二十圈的电感,电流足够时吸合带动机械杠杆而动作保护。
比较安全又不用换保险,是很好的推荐。
自动空气开关也称为低压断路器,可用来接通和分断负载电路,也可用来控制不频繁起动的电动机。
它功能相当于闸刀开关、过电流继电器、失压继电器、热继电器及漏电保护器等电器部分或全部的功能总和,是低压配电网中一种重要的保护电器。
自动空气开关具有多种保护功能(过载、短路、欠电压保护等)、动作值可调、分断能力高、操作方便、安全等优点,所以目前被广泛应用。

ABB’s Low Voltage Products Division is proud to present SACE Emax 2,its next generation of air circuit-breakers. Over 70 years of cutting edge research and experience inthe electromechanical industry has allowed ABB SACE to create this new benchmark of air circuit-breakers. Not only does Emax 2 meet or exceed the standard performances and functions that the market demands from an air circuit-breaker, but it has evolved into a true power manager. Emax 2 and its Ekip brand of trip units and accessories contain the perfect blend of control, connectivity, performance, ease of use and safety to efficiently satisfy any application or need.− A patented, Power Controller moni-tors and controls power usage toreduce management costs.−Extensive, direct communication abilities simplify network integrationand eliminate the need for costly and difficult conversion components.−Optimal frame organization and ac-curate design provide the ability forhigh performance switchboards andswitchgear with a reduction of bothmaterials and space required.−Busbar friendly, modifiable terminals eliminate the need to bend and ex-tend bus bar and provide quick, easy installation.−Large, color touchscreen interfaces allow for clear navigation, creating asimple and quick way to find informa-tion or make adjustments.− A wide variety of accessories have been designed to simplify use orinstallation and to increase safety.−The Emax 2 contains several features that are either new to the market orsuperior to existing solutions, mak-ing it the best choice for low voltage network needs.ControlThe Power Controller function of Emax 2uses a patented algorithm to determinethe average absorbed power over aperiod of time and then controls a loadlist to maintain the maximum power limitspecified by the user. The elimination ofinstantaneous based measurements andability to synchronize with utility mea-surement devices creates an efficientenvironment that saves on electricitybills without the need for additionalmonitoring systems.The Ekip Link system and Ekip ControlPanel enable local monitoring of circuit-breakers and switchgear functions in anindividual switchboard. They require noprogramming and are available for eventhe most basic Emax 2 trip unit, provi-ding an economic way for a small plantto increase monitoring capabilities or alarge plant to simplify local supervisionand maintenance.A Network Analyzer feature is able onEmax 2 to analyze the quality of powerin real time, with extreme precision inaccordance with EN 50160 and IEC6100-4 30. As a result, it is possibleto identify the causes of an increase ofpower lost or a reduction of the workinglife of cables and capacitors without ha-ving to install costly, external instrumen-tation. With Emax 2’s Network Analyzer,malfunctions can be prevented andinstallation efficiency and the workinglife of appliances can be increased.The Ekip Synchrocheck module enablesthe control of the synchronism conditionfor placing two lines in parallel beforeenabling circuit breaker closing.The ability of the Emax 2 to provide thisfeature as a module eliminates the needfor the purchase and installation of inde-pendent monitoring systems.Emax 2 offers Generator versions of itsEkip Touch and Ekip Hi-touch trip units.These trip units include all the functionsof true generator protection switchgearwithout the need for external relays ordevices, wiring or inspections. The Gversion offers a safe control solutionthat is immediately ready for use.ConnectivityEvery Emax 2 can be equipped with multiple cartridge-type communication modules at any time. The modules allow the circuit breakers to be directly integrated into automation and ener-gy management systems through the seven most popular global protocols; including IEC 61850 for the creation of Smart Grid Networks. All functions can be accessed via the internet, in comple-te safety, using the Ekip Link switchgear monitoring system.Not only can the rear terminals of Emax 2 be field rotated from horizontal to vertical, but they have been specifically designed to fit the most common bus configurations. Each terminal has been created to the standard width of bus bar for that amperage and is equipped with one, two or three terminal stabs for easy connection of one to four bus runs. The terminal technology provides the oppor-tunity for easy connection and installati-on with less bus bar stock required.The Ekip Supply Module can be con-nected to any voltage in AC or DC to internally supply auxiliary power for the trip units and terminal box modules consecutively. The need for any external power supply converter elsewhere in the cabinet is eliminated, saving both space and cost.The neutral position on Emax 2 can be modified from left to right to provide ultimate flexibility. In addition, the E6.2 is available with neutral conductor sizes of 50% or 100% to allow for the correct sizing of bus bar and an opportunity to reduce construction costs. PerformanceEmax 2 uses four frame sizes, each only as wide as the amperage need requires, so that designers can optimize their space and material. The breaker design and quality materials allow for a small size while maintaining the high perfor-mances required by the most deman-ding conditions.The family of Emax 2 contains:−E1.2, 1600A with a 440V Icu of 66kA and Icw 1s of 50kA in a 210mmwidth.−E2.2, 2500A with a 440V Icu of100kA and Icw 1s of 85kA in a276mm width.−E4.2, 4000A with a 440V Icu of150kA and Icw 1s of 100kA in a384mm width.−E6.2, 6300A with a 440V Icu of200kA and Icw 1s of 120kA in a762mm width.Emax 2 contains new generationRogowski sensors that allow the mostprecise measurement on the market.The tolerance to 1% of the actual valueof current, 0.5% of voltage and 2% ofpower and energies guarantee precisionand enable the circuit-breaker to act asa measurement device in switchgear.Measurements can be read directly onthe wide trip unit display so additionaldevices can be eliminated.The Ekip Fan Module continuouslymonitors the internal temperature at thefixed part and activates cooling fans ifrequired. This allows for the ability ofincreased current-carrying capacity inswitchgear.Ease of use and safetyEmax 2 is the first circuit-breaker tooffer large, color touch screen displays.They provide clear, easy navigation forquick access to information and adjust-ment capability that is invaluable in theevent of a fault or emergency.The trip units are capable of ten langu-ages, reducing the need for extensivetraining. In addition, they can be readand used directly, without the need forexpensive HMI units.If desired, they can also be program-med and consulted from a tablet, smartphone or PC via the Ekip Connectapplication.Removal of the main Emax 2 cover al-lows access to the accessory mountingarea only, not the operating mechanismor other components.This protects both maintenance person-nel and the breaker itself from unwanteddamage. In addition, the key lock ac-cessory is mounted inside the acces-sory area and allows for the breakerto remain locked, avoiding unwantedoperation during maintenance.Dedicated guide rails simplify movementand allow correct, locked and clearlyidentifiable positioning. The rails extendoutside the fixed part so that the mobilepart can be easily inserted. In addition,shutters on the fixed part can be lockedfrom the front, without access throughthe inside of the fixed part. These fea-tures allow for easy and safe installationand maintenance.Implementation of breaker settings issimplified with the aid of ABB’s DOCsoftware and Ekip Connect interface.Curves and settings can be determi-ned and saved using the DOC softwareand the Ekip Connect program canopen and read the DOC file, eliminatingthe need to retype the settings intothe breaker or software program andallowing for easy, error free implemen-tation.Emax 2 contains push in terminal boxtechnology, making wiring easy andtooling-free. This feature ensures imme-diate, safe wiring. In addition, Emax 2terminal boxes and wiring set ups arecommon across the line and its tripunits are field interchangeable, creatingflexibility and the potential for easy,rapid upgrades without the added costof a service technician.ABB SACEA division of ABB S.p.A.L.V.

开关柜进线断路器起着母线配电盘柜与上游电源连接的重要作用,若进线断路器动作跳闸,其所连接的整个母线配电盘柜及下游负荷均将失去电源,若母线段配有母联开关,则母联开关动作合闸,母线段将恢复供电。
田湾核电站现场低压配电开关柜的进线断路器和母联开关均为ABB厂的Emax断路器,主体框架结构相同,为可抽出式,采用后接线方式。
设备从现场安装、调试、投入运行到设备老化更新,使用寿命在20年,经过维护和升级翻新后,可将使用寿命延长。
