Features of high voltage gas insulated switchgear
May 20, 2021
Indoor AC high voltage gas insulated switchgear is a new generation of switchgear. It is suitable for small secondary substations, switching substations, box-type substations, residential quarters, industrial and mining enterprises, large shopping malls of the power system, and is especially suitable for occasions with high power requirements such as airports, subways, and railways.
1. RMU room: A three-station load switch can be installed in the switch room. The shell of the load switch is made of epoxy resin and filled with sulfur hexafluoride (SF6) gas. There is an observation hole on the shell and a SF6 gas density meter.
Power distribution cabinet, high voltage power distribution cabinet, low voltage power distribution cabinet, high and low voltage power distribution cabinet, JP cabinet integrated power distribution box, box transformer
2. Low-voltage room: The high-voltage switchgear installation manufacturer stated that the low-voltage room with interlock also functions as a control panel, and the low-voltage room is equipped with a spring operating mechanism with a position indicator and a mechanical interlock device.
3. The high-voltage gas insulated switchgear adopts aluminum alloy profile frame and aluminum-zinc steel plate, which is luxurious and beautiful, safe and reliable. The main switch and the cabinet are fixedly installed, and the entire inflatable cabinet can be divided into upper and lower parts. The upper part of the cabinet includes the instrument room, busbar room, switch room, low voltage room, and is separated from the lower cable room (outgoing cabinet with fuse) To avoid mutual influence. The overall dimensions (height × width × depth) are 1600 (2000) × 500 (750) × 1000, etc.
4. Instrument room: The instrument room can be installed; voltmeters, ammeters, measuring instruments, live monitors, relay protection, etc.
5. Cable room: There is ample cable room for easy cable connection. There is ample space to install fuses, lightning arresters, voltage transformers, current transformers, grounding switches and other components. The cabinet doors have observation windows and safety interlocking devices. .
6. Busbar room: The busbar room is arranged on the upper part of the cabinet, and the three-phase main busbar is arranged horizontally and runs through the entire row of switch cabinets.
