Indoor Electrical Live Display High Voltage Indicators No Maintenance Long Life

GSN-T Indoor High Voltage Indicator with Switchgear equipment

1. 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.

2. 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.

3. Middle cabinet, all known as metal armor in the case of a shift switch equipment. It is a high voltage distribution unit with a maximum operating voltage of 3.6 / 7.2 / 12kV and is an indoor distribution unit of a three-phase AC 50 Hz single bus segment system or a double bus segment system. It is used to receive and match the network electricity of 3.6-12kV, and to control, protect, monitor and measure the electric circuit. Medium type switchgear is mainly used for power plant, small and medium power generator, power substation of power system, power supply, power distribution of industrial and mining enterprises, and starting of large high voltage motor.
