Chemical production are introduced in this device connecting equipment distribution equipment in the contactor in system in electric vehicle movement caused by equipment,resulting in key equipment trip caused a parking or local chemical production equipment,leading to the production process is disorder,so according to different equipment is reformed,in the sway can be automatic recovery when electricity or by electric time delay from shakes,maintain the normal production system.%介绍了化工生产装置中转机设备的配电装置接触器在系统晃电时动作造成设备跳车，进而引起关键设备跳车造成化工生产装置停车或局部停车，进而导致生产工艺过程紊乱，因此针对不同设备进行了改造，使其在晃电时能自动恢复或通过延时躲过晃电时段，保持系统正常生产。
