摘要
采用24 V和48 V小型中间继电器,设计了6款出口继电器,额定工作电压分别为110 V和220 V。配置0.095~1.482 uF 6种控制电缆对地电容,试验、测量出口继电器的交流窜入误动时的最低交流电压,并进行了数据分析。并联电容虽可防止交流窜入引起保护误动,但出口继电器动作时间将相应延长,对切除一次设备故障不利。
In this paper, 24 V and 48 V intermediate relay is used to design designed six models outlet relay, rated working voltage is 110 V and 220 V respectively. Configures six control cable capacitance to ground between 0. 095 and 1. 482 uF. Tests and measures the minimum AC voltage of outlet relay when AC fleeing malfunction, and analyzes the data. The shunt, capacitance although prevents protection misoperation caused by exchange fleeing, the action time of outlet relay will be extended accordingly. It is detrimental to resection of the primary equipment failure.
