产品详情资料

  正向接触器在电弧熄灭之前断开。该电路在带有“插头停止”的控制器中是必要的，或者在向前运行时按下一个瞬时触点会拾取换向接触器。电流联锁通常不用于检修负载，如矿井提升机，因为在下降循环期间，可能没有足够的电流来操作联锁继电器。标准Limitamp换向控制器上不提供此电路，因为操作员只能在按下STOP（停止）按钮后才能将选择开关转到倒车档。电位联锁电位联锁的使用原因与当前联锁相同。增加了电压互感器和联锁继电器，以防止一个主接触器在另一个（反向）接触器的电弧完全中断之前闭合。操作的原则是，当断开的电机产生的电动势衰减到联锁继电器断开的程度时，断开的接触器中的电弧已经熄灭，允许闭合换向接触器。潜在联锁用于起重机和其他可能有检修负载的应用。仪表电流表电流表（面板型或配电盘型）用于指示电机电流或总输入电流。它可以硬接线到一个相位或所有相位的电流互感器forward contactor opens but before the arc has been extinguished. This circuit is necessary in controllers with “plug stop” or where pressing one instantaneous contact picks up reversing contactor while running forward. Current interlocking is not normally used on overhauling loads such as mine hoists, since during the lowering cycle enough current may not be drawn to operate the interlocking relays. This circuit is not supplied on standard Limitamp reversing controllers, as the operator is expected to turn the selector switch to reverse only after pressing the STOP button. Potential Interlocking Potential interlocking is used for the same reason as in current interlocking. Potential transformers and interlocking relays are added to prevent closure of one primary contactor before complete interruption of the arcs at the tips of the other (reverse) contactor. Operation is based on the principle that by the time the disconnected motor’s generated EMF has decayed to the point where the interlocking relays have dropped out, the arc in the disconnected contactor has extinguished, and closing the reversing contactor is permissible. Potential interlocking is used on hoists and other applications having possible overhauling loads. Instrumentation Ammeter An ammeter (panel-type or switchboard-type) is used to indicate either motor amperes or total incoming amperes. It can either be hardwired to the current transformer of one phase or all
