摘要
500kV变电站预试验期间,由于所有的保护屏柜都装设在保护室内,与主控室后台相隔距离较远,因此开关干接点的开/关状态需要手动计数,保证与状态同步,对人力和精力提出了很大要求。基于此,提供了一种智能化干接点开关通断信号装置,经过即时收集、传输、接收和展示,可以精确记录干触点的通断情况,提高测试精度与信度可靠性。
During the pre-test of 500kV substation,because all the protective cabinets are installed in the protective room and are far away from the backstage of the main control room,the on/off state of the switch trunk contacts needs to be counted manually to ensure synchronization with the state,which requires a great deal of manpower and energy.Based on this,an intelligent on-off signal device for dry contact switch is provided.Through real-time collection,transmission,reception and display,the onoff situation of dry contact can be accurately recorded,and the test accuracy and reliability can be improved.
