Installation process of low voltage switchgear

Low-voltage switchgear plays the role of blocking, controlling or protecting the power generation, transmission, distribution, power conversion and consumption of the power system. It is suitable for power stations, petroleum, chemical, metallurgy, textile, high-rise buildings, etc., and is used for power transmission and distribution. Electricity and electrical energy conversion.

Find the main screen position of the low-voltage switchgear, usually find the main change line or main screen of the main screen, find the three-point one-line method, that is, the phase center of the wall sleeve, the main screen entrance center and the main screen front cover center. Multiple rows of low-voltage switch cabinets are connected to the bus bridge. First, locate the low-voltage switch cabinet on the main conversion line, and then use the four-point single-line method to find the side of the low-voltage switch cabinet on the side of the kiln bridge under the opposite situation. The switchgear finds the busbar bridge high voltage cabinet, so no matter how many low voltage switch cabinets are specified. At this time, please note that the two rows of high voltage cabinets connected to the bus bar bridge are reversed.

It must be noted that during the installation process, if there is no reverse order, corresponding rectification must be performed. After the screen is positioned, the level level is immediately hit to see if a washer pad is needed, and then the electric welding is fixed immediately after the level is completed. Close the other low-voltage switchgear facing the main screen. The low-voltage switch cabinets are tightened by connecting screen screws. When the low-voltage switch cabinet is in place, there is one front and rear. Open the front and rear cabinet doors and the busbar door panel and the top door of the busbar door panel. During the continuous screen process, you should have a main screen to turn off. To save the front panel screws of the front cabinet door, tighten the door.
