JSN (W) electromagnetic lockIt is a mechanical lock used for high-voltage switchgear. This lock forces operators to operate electrical equipment according to the prescribed safety operating procedures, thereby avoiding misoperation of electrical equipment
A relatively complete achievement has been made to meet the requirements proposed by the power supply department:


Prevent accidental opening and closing of switches; b、 Prevent the isolation knife switch from being pulled and closed under load; c、 Prevent accidental entry into electrified compartments;
d、 Prevent the hanging of live grounding wires (grounding gates); e、 Prevent grounding wires (grounding gates); Close the switch; Waiting for the five defense requirements.
This product is an ideal anti misoperation device for high-voltage electrical equipment sand pots. This product has the ability to distinguish between various knife switches, opening and closing positions, and mesh door opening and closing positions
It has high performance and does not require the key to be turned back during operation. Only one key is needed to complete multiple operations in one circuit according to the specified program.



The altitude shall not exceed 2000 meters.
The ambient air temperature shall not exceed+40 ℃, not be lower than -5 ℃, and the average temperature within 24 hours shall not exceed+35 ℃.
The installation location has clean air, and the relative humidity of the atmosphere should not exceed 50% when the ambient temperature is 40 ℃. The average relative humidity in humid months is 90% when the average temperature is 25 ℃, taking into account the condensation that occurs on the surface of the product due to temperature changes.
