The application explains and analyzes the structure of the cabin. Below, we will combine the above categories with reality

1. Structural analysis of 10kV voltage prefabricated cabin

①. According to the compensated capacity, it can be divided into 5Mvar or less.

5Mvar prefabricated cabins mostly use a standard delivery size of 40 feet.

That is, 12200mm(L)x2440mm(W)x2890mm(H), the size can be slightly adjusted according to the actual application, the height adjustment range is relatively loose (between 100mm and 200mm), if the size adjustment is too large, it will greatly increase the transportation cost ( Consider traffic and road administration fines).

Depending on the application, there is also a smaller capacity SVG compensation device, and the standard delivery size is 20 feet.

Namely: 6058mm(L) x 2438mm(W) x 2591mm(H)

② The cabin is divided into three areas, separated by partitions:

SVG control room,

SVG compensation room,

SVG charging room,

1. SVG control room:

The control room is generally equipped with one or two intelligent control systems,

Distribution boxes, lights, heaters, thermostats, open-loop or closed-loop coolers,

The distribution box supplies power to the control system and the entire cabin's lighting, smoke alarms, heaters, and other equipment. The wires pass under the floor of the cabin and are hinged on the inspection cover.

The cabinet of the control system adopts the cable routing method under the floor, and sends the input and output signal lines of the control line to the SVG compensation room area through the cable channel under the floor. The control system cabinet adopts upper and lower fixed type to ensure that the bumps of the cabin body during transportation will not cause damage to the electrical components.

Since the control system cabinet is equipped with more sophisticated equipment, the control cabinet body needs to ensure the seismic strength and anti-shake strength required for transportation:

Since the control system cabinet is equipped with more sophisticated equipment, the control cabinet body needs to ensure the seismic strength and anti-shake strength required for transportation:
