DXN-Q Indoor High Voltage Indicator with Switchgear equipment
In view of the problems existing in the old high-voltage electric display device, a new type of electric display device with high reliability, long life, no maintenance, clear and striking display can compensate the defect of the old high-voltage electric display device. The Beijing Power Supply Bureau has developed a new type of high voltage electric display and electric inspection device, which is used in conjunction with CG sensors, and can be used by means of electric display and on-site inspection to show whether the high voltage equipment has operating voltage and electric forced locking function.
The device solves many problems of neon lamp type electric display device. The old type of high-voltage electric display device with mandatory electrical latching, which is too simple in principle, consists of half wave rectifying and directly combining the signals from the A, B and C phase sensors to control the latching circuit. In this way, when the system has an anomaly of single phase grounding or absence phase, the drift of the locked-in control voltage can lead to the accident of the electrically connected grounding switch.
