L-6/T high voltage LIVE displayer (L-6/Q with switch)

Scope And Characteristics

The indoor high-voltage LIVE displayer device is composed of three sensors and one displayerconnected by wires. Applicable to indoor high-voltage electrical equipment with Rated frequency of 50Hz and rated voltage of 40.5kV or less, it can reflect the LIVE condition of the circuit, and can also cooperate with the electromagnetic lock to realize the forced lock switch handle and valve.

Both the LIVE displayer and the forced lock are controlled by the same high-voltage signal, but the circuit system is independent of each other and does not interfere with each other. As long as the high-voltage circuilt is LIVE, even if the displayer circuit and the latching circuit fail at the same time, the electromagnetic lock is still locked, and the error is prevented. Operation, mistakenly enter the charging interval.
