二次回路图都懂了吗？3分钟帮你搞清楚！

二次回路（secondary circuit）定义：测量回路、继电保护回路、开关控制及信号回路、操作电源回路、断路器和隔离开关的电气闭锁回路等全部低压回路。由二次设备互相连接，构成对一次设备进行监测、控制、调节和保护的电气回路称为二次回路。是在电气系统中由互感器的次级绕组、测量监视仪器、继电器、自动装置等通过控制电缆连成的电路。用以控制、保护、调节、测量和监视一次回路中各参数和各元件的工作状况。用于监视测量表计、控制操作信号、继电保护和自动装置等所组成电气连接的回路均称为二次回路或称二次接线。https://p26.toutiaoimg.com/img/pgc-image/b27c2d0288cd443aa521746cbdbae2d7~tplv-tt-shrink:640:0.image
