Thus, the three-phase monitoringrelays of the CM range, according to the individual requirements,m onitor the phase voltages, phase sequence, phase unbalance,phase failure and the neutral:Monitoring for over- and undervoltageAll electric devices can be damaged when operated conti-nuously at voltages over or under their rated values.An overvoltage could potentially cause heating within thedevice. If the temperature is unduly high, component partsand thus whole devices or installations may fail or may bedestroyed. Undervoltages involve the risk that the switchingelements reach an undefi ned region. In this case, parts of theinstallation still function, but not others. This misoperation canresult in damage of the product or installation. In the worstcase, wrong voltages may even cause harm to the operatingpersonnel.Phase unbalance monitoringIf the supply by the three-phase system is unbalanced dueto uneven distribution of the load, the motor will c onverta part of the energy into reactive power. This energy getslost u nexploited; also the motor is exposed to h ighert hermal strain. Other thermal protection devices fail to de-tect c ontinuing unbalances which can lead to damageor d estruction of the motor. The CM range three-phasem onitoring relays with phase unbalance monitoring canr eliably detect this critical situation.Phase failure detectionIn case of a phase loss, undefi ned states of the i nstallationare likely to occur. E.g. the startup process of motors isd isturbed. All three-phase monitoring relays of the ABB CMrange detect a phase loss as soon as the voltage of onep hase drops below 60 % of its nominal value.Phase sequence monitoringAn incorrect phase sequence applied at start-up or a changeof the phase sequence during operation will cause a 3-pha-se motor to run with reverse rotation. Certain motors whenoperated in the reverse direction will cause severe damage toconnected loads such as pumps, screw compressors and fans.Especially for non-fi xed or portable equipment, such as construc-tion machinery, phase sequence detection prior to the start-upprocess is highly recommended. ABB offers three-phase monitorswith selectable phase sequence monitoring. This provides thecapability of ignoring phase sequence conditions for applications,such as motors with forward and reverse rotation, where the pha-se sequence is unimportant.Interrupted neutralUnder normal conditions, individual phase voltages are equal andthe load causes the individual phase currents to vary. Systemsthat have neutral conductors accommodate this variation by acompensating current fl ow through the neutral conductor. If theneutral conductor breaks, the compensating current can no lon-ger fl ow. As a result, the voltage is divided asymmetrically on theindividual phases. This means that over- and undervoltages areproduced in the individual phases and these can damage or evendestroy the connected consumers. ABB offers three-phase mo-nitoring relays that monitor the neutral conductor for interruptedneutral. The interruption of the neutral is detected by means ofphase unbalance monitoring.Three-ph a se m o n i t o ri ngN E WG E N ER A T I ON2008.10.0152C D C 252 086 F 0b 072C D C 252 087 F 0b 07Three-phase monitors CM rangeAutomatic phase sequence correction The new generation of ABB three-phase monitoring relays offers devices with automatic phase sequence correction.

北京市ABB继电器TA75DU42M
ABB热继电器是由流入热元件的电流产生热量,使有不同膨胀系数的双金属片发生形变,当形变达到一定距离时,就推动连杆动作,使控制电路断开,从而使接触器失电,主电路断开,实现电动机的过载保护。
继电器作为电动机的过载保护元件,以其体积小,结构简单、成本低等优点在生产中得到了广泛应用。
主要用来对异步电动机进行过载保护,他的工作原理是过载电流通过热元件后,使双金属片加热弯曲去推动动作机构来带动触点动作,从而将电动机控制电路断开实现电动机断电停车,起到过载保护的作用。
鉴于双金属片受热弯曲过程中,热量的传递需要较长的时间,因此,热继电器不能用作短路保护,而只能用作过载保护热继电器的过载保护.热继电器工作原理:0577保2788顺2628热继电器是用于电动机或其它电气设备、电气线路的过载保护的保护电器。
电动机在实际运行中,如拖动生产机械进行工作过程中,若机械出现不正常的情况或电路异常使电动机遇到过载,则电动机转速下降、绕组中的电流将增大,使电动机的绕组温度升高。
若过载电流不大且过载的时间较短,电动机绕组不超过允许温升,这种过载是允许的。
但若过载时间长,过载电流大,电动机绕组的温升就会超过允许值,使电动机绕组老化,缩短电动机的使用寿命,严重时甚至会使电动机绕组烧毁。
所以,这种过载是电动机不能承受的。
热继电器就是利用电流的热效应原理,在出现电动机不能承受的过载时切断电动机电路,为电动机提供过载保护的保护电器。
使用热继电器对电动机进行过载保护时,将热元件与电动机的定子绕组串联,将热继电器的常闭触头串联在交流接触器的电磁线圈的控制电路中,并调节整定电流调节旋钮,使人字形拨杆与推杆相距一适当距离。
当电动机正常工作时,通过热元件的电流即为电动机的额定电流,热元件发热,双金属片受热后弯曲,使推杆刚好与人字形拨杆接触,而又不能推动人字形拨杆。
常闭触头处于闭合状态,交流接触器保持吸合,电动机正常运行。
若电动机出现过载情况,绕组中电流增大,通过热继电器元件中的电流增大使双金属片温度升得更高,弯曲程度加大,推动人字形拨杆,人字形拨杆推动常闭触头,使触头断开而断开交流接触器线圈电路,使接触器释放、切断电动机的电源,电动机停车而得到保护。
相序保护继电器的概述
相序保护继电器的概述相序保护继电器是电力系统中的一种重要保护装置,用于监测和保护电网中的相序和相序幅值不平衡情况,确保电力系统的稳定和安全运行。
它通过检测电网中的相电压和相电流,判断电网中的相序情况,并根据预设的相序保护准则进行动作,采取措施对电网进行保护。
1.监测相序:相序保护继电器可以监测电网中的相电压和相电流的相位关系,判断电网中的相序是否正确。
若相序正确,则继电器不动作;若相序错误,则继电器进行相序保护操作。
2.故障检测:相序保护继电器可以检测电网中的相序幅值不平衡情况,即相电压或相电流的幅值不均衡程度。
当相序幅值不平衡超过设定值时,继电器会进行动作,发出警报或采取措施对电网进行保护。
3.响应速度快:相序保护继电器具有快速响应的特点,可以及时检测电网中的相序问题,并迅速采取保护措施。
这对于保护电网的稳定运行至关重要,特别是在面临突发故障或异常情况时。
4.可靠性高:相序保护继电器具有高可靠性和稳定性,能够在各种环境条件下正常工作。
同时,它还具有自我检测和故障诊断功能,能够及时发现和修复自身的故障,确保继电器的正常运行。
5.多种保护功能:相序保护继电器通常还具有其他保护功能,如过电流保护、短路保护、接地保护等。
这些保护功能的综合应用可以有效地保护电网系统,提高电力系统的可靠性和稳定性。
1.测量相电压:相序保护继电器通过电压互感器等装置,测量电网中各个相电压的幅值和相位。
2.测量相电流:相序保护继电器通过电流互感器等装置,测量电网中各个相电流的幅值和相位。
3.判断相序:根据测量到的相电压和相电流的幅值和相位信息,相序保护继电器判断电网中的相序是否正确。
4.触发动作:若相序错误或相序幅值不平衡超过设定值,相序保护继电器会触发动作信号,并采取措施对电网进行保护,如切断电路、发出警报等。
总之,相序保护继电器是电力系统中非常重要的保护设备,它能够及时监测和保护电网中的相序和相序幅值不平衡情况,确保电力系统的稳定和安全运行。
