Installation method of high-voltage switchgear

1. First is the inspection

For the unpacked switchgear, check the quantity and specifications carefully according to the design drawing and the imitation list, and check whether it meets the requirements.

Fengyuan Power Tips: Check whether the enclosure of the high-voltage switchgear is damaged or corroded. Check whether the accessories and spare parts are complete.

2. After the switchgear is placed on the channel steel, the high-voltage cabinet should be roughly adjusted to the level with a thin shim, and then one of the cabinets should be used as a benchmark to adjust the others so that all the high-voltage cabinets have the same panel surface and uniform clearance.

3. Connect the bus duct

The main bus bar and instruments on the switchgear are provided by the switch factory, or can be made according to the design drawings at the construction site. The connection of the main bus, the connection between the main bus and the lower bus, and the connection between the bus and the instrument are connected by bolts. The connection surface of the bus bar should be coated with power compound grease. The tightening degree of the bolts and the connection status of the connecting surface are controlled by tightening the bolts according to the specified torque value by a torque wrench;

4. Installation of handcart type high voltage switch cabinet

The installation method is basically the same as that of the fixed high-voltage switchgear, but the difference is to ensure the interchangeability of the handcart. Each handcart type moving contact must be adjusted consistently. Adjust the center of the moving and static contacts to be consistent and close in contact to ensure interchangeability. Check the plugs and auxiliary contacts of the secondary circuit of the high-voltage power distribution cabinet, and the welding is reliable.
