Voltage relay

It is a relay that operates when the voltage in the circuit reaches a predetermined value.Its structure is basically the same as that of the current relay, but the number of turns of the electromagnet coil is many, and it should be connected in parallel with the power supply when used.It is widely used in voltage loss (zero voltage) and undervoltage (low voltage) protection.The so-called loss-of-voltage and under-voltage protection means that when the power supply voltage drops too much or the power is temporarily cut off for some reason, the motor is automatically disconnected from the power supply; when the power supply voltage is restored, if the start button is not pressed again, the motor cannot start by itself.If the relay control is not used, but the knife switch is directly used for manual control, because the switch is not opened in time during the power failure, when the power supply voltage is restored, the motor will start by itself, which may cause an accident.In addition, there is an overvoltage relay, which is a relay that cuts off the power supply due to the suction of the electromagnet when the circuit voltage exceeds a certain value. It is used for overvoltage protection (such as protecting silicon tubes and thyristor components).

A voltage relay is an electronic control device, it has a control system (also known as an input loop) and a controlled system (also known as an output loop), usually used in automatic control circuits, it actually uses a smaller currentAn "automatic switch" to control larger currents.Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.Mainly used in relay protection devices of generators, transformers and transmission lines, as a starting element for overvoltage protection or low voltage blocking.Voltage relay is a measuring relay whose input quantity and characteristic quantity are voltage. It is divided into over-voltage relay and under-voltage relay.The former acts when the voltage value increases and reaches the set value, and then is in a post-acting state; the latter acts when the voltage value decreases and reaches the set value, and then is in a release state.Voltage relays include electromagnetic type and transistor type.
