The DXW high-voltage live display device is mainly suitable for indoor and outdoor high-voltage electrical equipment networks with AC 50HZ and rated voltage of 35-500KV. It can accurately detect whether the equipment is live online to prevent electrical misoperation, and is an intelligent safety device for mechatronics integration. This device has a remote interface that can transmit live signals to the control center through optical, telephone, SMS, and GPRS methods, providing advanced technological means for safety production.

The DXW high-voltage online detection live display locking device adopts a non-contact sensor. The sensed electric field signal is filtered, amplified, deformed, and compared. After processing, the MCU detects whether the equipment is live according to a pre-set program, drives the display circuit and alarm device, and locks the relay contacts with the microcomputer. Electromagnetic lock locking and mechanical program locking are combined to implement forced locking, reliably preventing live errors, grounding knife switches or live hanging ground wires. This device is installed on the grounding knife switch of the line and the grounding knife switch of the ground wire, as well as to lock the active line ground wire and live interval.
