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.

ABB SACE offers a dedicated device – RRD - to remotely perform Emax circuit-breaker racking in and racking out operations in order to increase the safety of the personnel. ABB is constantly committed to the safety of the personnel during every phase of use of its products, including installation and maintenance. During the racking-in operations of the circuit-breaker, the RRD prevents from any risk of injuries due to any possible electric arc.Arc flashThe electric arc can occur because of several reasons, such as human mistakes and bad connections. Accidents are quite unusual but when they happen their consequences may be really severe. The main risk of arc flash occurs when the cabinet door is open and the arc-proof characteristics of the switchgear are significantly decreased.ABB SolutionIn order to maximize safety during the racking in of the CB moving part, ABB has developed the new Remote Racking Device - RRD - to operate Emax circuit-breakers without being in front of it.The device works with the circuit-breaker open and with the springs discharged.The RRD is supplied by the main grid. The remote control is connected to the main device with a thirty-foot cable which allows the racking in or out command from remote location. The cable length guarantees a far distance from the arc flash boundary for traditional LV switchgear.Advantages• Personnel safety increasing thanks to the long distance between the circuit breaker and the operator• One single device for all the Emax circuit-breakers (Emax and New Emax – from the smallest E1 3 poles up to the biggest E6 full size)• Easy installation thanks to the ergonomic handle to mount and to remove the device from the circuit-breaker• All the positions can be reached:Connected/ Disconnected/ Test position• Immediate visual check of the position reached thanks to the 3 Leds available both on the device and on the remote control • Possibility to interrupt the operation in any moment thanks to the emergency pushbutton on the remote control• Easy of storage thanks to the dedicated case:Power on to check the power of the device 1S D C 200027L 0201 - 2012.10Product 1SDA...R1RRD069965RRD adapter kit 069966ABB SACEA division of ABB S.p.A.L.V .

The kit can be ordered even as a loose accessory to allow the installation on other 5 additional Emax.To power the circuit-breaker it is necessary to disinstall the RRD device.Ordering codes:A bit of theory: What is an electric arc?The electric arc is a phenomenon that takes place as a consequence of a discharge. This occurs when the voltage between two points exceeds the insulating strength limit of the interposed gas. Gases, which are good insulating means under normal conditions, may become current conductors in consequence of a change in their chemical-physical properties due to a temperature rise or to other external factors. In case of abnormal conditions (e.g., doors open or closed, rack in or rack out) mentioned in NFPA 70E-2009, 130.7 (C)(9) FPN 2 (see doc 1SXU210018L0201), even in case of closed door, the arc flash effect cannot be easily analyzed. In order to improve personnel safety it is suggested to increase the distance between the door and personnel.The remote controlpushbuttons to reach the wanted positionReady to work led to check the correct mounting of the device onthe CB LEDs to indicate the position reachedEmergency pushbutton to interrupt any operation。
空气断路器,就是空气开关,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。
在电路中作接通、分断和承载额定工作电流,同时能在线路和电动机发生情况时进行保护。
近年来,ABB旗下的空气断路器- Emax (新E型)在市场上备受欢迎,由于优异的性能,在市场上需求也越来越高。
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。
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。
空气断路器的优异性能主要得益于以下两方面:
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。
