Voltage relay is an electronic control device , It has a control system （ Also called input loop ） And the controlled system （ Also called output loop ）, Usually used in automatic control circuit , It's actually a way of controlling a larger current with a smaller current “ Automatic switch ”. So in the circuit plays an automatic adjustment 、 safeguard 、 Switching circuit, etc . Mainly used for generator 、 Relay protection devices for transformers and transmission lines , As the starting element of overvoltage protection or low-voltage lockout .

Voltage relay is an input 、 A measuring relay whose characteristic quantity is voltage , It is divided into overvoltage relay and undervoltage relay . The former acts because the voltage value increases to the set value , Then it is in the dynamic state ; The latter acts because the voltage value decreases to the set value , Then it is released . Voltage relay has electromagnetic type 、 Transistor type .
