Meaning of voltage relay model _ Text symbol of voltage relay
Release time:
2024-04-29
The textual symbol for voltage relays is KV Voltage relays are divided into three categories: overvoltage relays, undervoltage relays, and zero voltage relays. Overvoltage relay operates when the voltage of the parallel circuit exceeds its set value, mainly used for overvoltage protection of the circuit or equipment. The commonly used overvoltage relay is the jt4-a series, and its operating voltage can be adjusted within the range of 105% to 120% of the rated voltage.

Voltage relays are divided into three categories: overvoltage relays, undervoltage relays, and zero voltage relays. Overvoltage relay operates when the voltage of the parallel circuit exceeds its set value, mainly used for overvoltage protection of the circuit or equipment. The commonly used overvoltage relay is the jt4-a series, and its operating voltage can be adjusted within the range of 105% to 120% of the rated voltage. The undervoltage relay operates when the voltage of the parallel circuit drops to a specified range. Zero voltage relay is a special form of undervoltage relay that only operates when the terminal voltage of the relay drops or approaches disappearance. The commonly used undervoltage relays and zero voltage relays include the JT4-P series. The release voltage of the undervoltage relay can be set within the range of 40% to 70% of the rated voltage, and the release voltage of the zero voltage relay can be adjusted within the range of 10% to 35% of the rated voltage.
