HVD-QS 3.6kV-40.5kV Device Display High Indicator Circuit For Medium Voltage Switchgear
Description
The high-voltage live display device is a new type of non-contact high-voltage live detection device. It uses an integrated three-phase continuous display to test the voltage loss in the medium-voltage switchgear, which helps to ensure the safety of the power system. The device is not directly connected to the high-voltage live body Connection, can sense the electric field signal, accurately reflect the charging situation of the high-voltage electrified body, and has a reliable locking function.
The product meets the requirements of IEC 61243-5 and IEC 62271-213 standards, and is the first choice for indoor high-voltage electrical equipment to prevent accidental entry into live spaces and electrical misoperation. The device has the functions of flashing display, sound alarm, self-check, reset and start-up forced locking circuit. Cooperating with electromagnetic locks and microcomputer anti-misoperation locking functions, it is widely used in 7.2kV~40.5kV indoor and outdoor electrical equipment or networks. It is installed on line grounding switches, busbar grounding switches and busbar voltage change grounding switches to prevent The function of the charged grounding switch by mistake.
