GGX2-12G high-voltage vacuum switchgear

This product is an improved version of the GGX2-12 switchgear jointly designed by the original Ministry of Power and the Ministry of Machinery. It incorporates all the advantages of the GGX2-12 switchgear, making the internal structure of the switchgear more reasonable and reducing the cabinet volume; The modularization of the operating mechanism makes operation simpler, and the full mechanical "five prevention" interlocking is more reliable. The secondary protection can be either relay protection or microcomputer protection. With the powerful functions of the microcomputer, it is convenient to achieve telemetry, remote signaling, remote adjustment, and remote control functions. This product complies with standards such as GB3906, DL404, and lEC298.

This product is suitable for three-phase AC power systems with a rated voltage of 3.6-12KV and a frequency of 50Hz. It is used to receive and distribute electrical energy, and to control, protect, and monitor circuits.

Product features

The GGX2 switchgear is a box type fixed metal enclosed switchgear, and the cabinet frame is welded with angle steel or fully assembled. The switchgear consists of the following functional rooms, such as the main busbar room, small busbar room, instrument room, circuit breaker room, cable room, overhead busbar room, bypass busbar room, and the interlocking operation mechanism of the isolation switch installed in the middle right side of the cabinet.

The main function room is equipped with exhaust channels to release high-pressure gas generated by faults. Insulation sleeves are installed between cabinets to prevent the spread of faults.
