product details
scope of application
the indoor high-voltage live display device consists of three sensors and a display connected by wires. suitable for rated frequency 50 Hz, rated voltage 40.5 kV on the following indoor high-voltage electrical equipment, it can not only reflect the electrification status of the circuit, but also cooperate with the electromagnetic lock to achieve forced locking of switch handles, valves, etc. both the live display and the forced locking are controlled by the same high-voltage signal, but the circuit systems are independent of each other and do not interfere with each other. as long as the high-voltage circuit is charged, even if the display circuit and the locking circuit fail at the same time, the electromagnetic lock will still be in the locked state to prevent errors. operation, mistakenly entering the electrified interval.
