摘　　要：介绍了ZH-XQB系列电磁线圈保护装置的原理,阐述了保护装置的主要功能和抗扰度试验,列举了装置的应用范围。结果证明:ZH-XQB电磁线圈保护装置的限时断电和反向电动势吸收功能,可以有效保护高压断路器的合、分闸线圈,也可以保护电磁阀线圈。Introduction was made to the principle of ZH-XQB series electromagnetic coils protection device, main functions of the protection device and anti-interference test contents described and the application scope listed. The results prove that functions of time-limited powerdown and counter electromotive force in the device can effectively protect not only switching-in and switching-off coils of high-voltage circuit breaker, but also electromagnetic valve coils.

关 键 词：高压断路器 电磁线圈保护装置 限时断电 反向电动势吸收 电磁兼容
