摘　　要：针对目前低频低压减载保护装置测试方法的不足,设计一种低频低压减载出口快速测试专用装置。该装置运用保护跳闸出口压板的正电源来启动信号继电器,不仅能一次性快速记录每一轮低频低压减载出口压板的动作信息,还能自保持和防止误操作,解决万用表测量法需要多次启动保护装置的问题。测试结果表明,该方法可有效地应用于低频低压减载保护装置的测试,且测试结果稳定可靠。A Special device for fast test of low frequency and low voltage load shedding has been designed aiming at the shortage of low frequency and low voltage testing methods for protection devices at present. The device was used to protect the positive power supply to start the signal relay, which can not only measure every round of the action information of tripping outlet pressing boards at one time quickly, but also maintain and prevent misuse. The device effectively solve the multiple start problem of multimeter measurement. The experiments show that the device can be effectively used in the measurement of low frequency and low voltage load shedding, and the measurement results are stable and reliable.
