继电器主要用于控制与保护电路作信号转换用。它具有输入电路(又称感应元件)和输出电路(又称执行元件)。当感应元件中的输入量(如电流、电压、温度、压力等)变化到某一定值时继电器动作,执行元件便接通和断开控…… 继电器主要用于控制与保护电路作信号转换用。它具有输入电路(又称感应元件)和输出电路(又称执行元件)。...

电机要实现正反转控制,将其电源的相序中任意两相对调即可(我们称为换相),通常是V相不变,将U相与W相对调节器,为了保证两个接触器动作时能够可靠调换电动机的相序,接线时应使接触器的上口接线保持一致,在接触器的下口调相。由于将两相相序对调,故须确保二个KM线圈不能同时得电,否则会发生严重的相间短路故障,因此必...
常规变电站的二次回路有两种:直流回路和交流回路。直流回路的功能:控制、保护逻辑、信号。交流回路的功能:保护、测量、计量。 到了智能变电站时代,一次设备与保护、测控之间的电缆被光缆取代,电缆中传输的直流信号(正电压/负电压/地电压)和交流信号(CT、PT二次电流、电压)被网络中传输的报文取代,过去用于实现保护逻...
