Description

失压保护

失压保护:防止电源电压消失后,电压恢复时电动机自起动的保护

自起动的危害:

1)造成人身事故、设备事故。

2)多台电动机自起动造成电网不允许的过电流及电压降。

失压保护装置:按钮和接触器(自锁)

欠电压保护

欠电压保护:电源电压降低到(0. 6一0. 8UN)时,切断电源。

欠电压保护:防止电网电压的降低使电器释放,造成电路不正常而进行的保护。

欠压保护装置:按钮和接触器(自锁)、电压继电器。

电压继电器的吸合电压整定:0.8一0.85URT

电压继电器的释放电压整定:0.5一0.7URT.

过电压保护

过电压保护: 为感性负载提供放电回路

                           过电压继电器
