GL-3 Nuclear Phase High Voltage Indicator with SF6 Sulphur hexafluoride Switchgear 

    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 dual display of LCD and long-life flash electric inspection plug-in is suitable for the operation environment of all kinds of light. The special electric test plug-in constitutes the unique independent electric test function, which improves the reliability of the device as the basis of electric test. The device adopts phase-splitting detection digital superposition locking control technology, which can ensure that the locking voltage is constant and stable when the system lacks the equivalent abnormal operation. Compulsory electrical locking function, can be reliable locking ground switch(switch cabinet door). The application of the new high voltage electric display and electric inspection device can effectively prevent the accident caused by the electric gap or the electric connected ground switch.
