| 完成高压真空断路器合闸、 Complete the closing of high voltage vacuum circuit breaker, 分闸任务的电气回路称为控制电路。控制电路按操作电源的种类可以分为直流操作和交流操作两类；按采用的接线和设备分，有强电控制和弱电控制两类。 The electrical circuit of the switching task is called the control circuit. The control circuit can be divided into two types according to the types of operation power, DC operation and AC operation. According to the wiring and equipment used, there are two kinds of strong electric control and weak current control. 一、接触器 1. Contactor 接触器分为交流接触器(电压AC)和直流接触器(电压DC)，它应用于电力、配电与用电场合。接触器广义上是指工业电中利用线圈流过电流产生磁场，使触头闭合，以达到控制负载的电器。 The contactor is divided into AC contactor (voltage AC) and DC contactor (voltage DC). It is applied to electric power, distribution and electric field. In a broad sense, the contactor refers to the use of a coil to produce a magnetic field in which the coil flows through the current, so that the contact is closed to control the load. 二、高压真空断路器 Two. High voltage vacuum circuit breaker 高压真空断路器是指能够关合、承载和开断正常回路条件下的电流并能关合、在规定的时间内承载和开断异常回路条件下的电流的开关装置。高压真空断路器按其使用范围分为高压高压真空断路器与低压高压真空断路器，高低压界线划分比较模糊，一般将3kV以上的称为高压电器。 High voltage vacuum circuit breaker is a switchgear which can turn on, load and disconnect the current under normal loop condition and turn it off, and load and disconnect the current in the abnormal loop within a specified time. High voltage vacuum circuit breaker is divided into high-voltage vacuum circuit breaker and low voltage high voltage vacuum circuit breaker according to its scope of application. The division of high and low voltage boundary is fuzzy. Generally speaking, more than 3kV is called high-voltage electrical apparatus. |
