Product Description

 

Product Description

Steel Plate Type Outdoor Pre-Installed Substation Grid Substation Mobile Substation

(1) Box shell

European box change box shell with steel structure as the main body, four sides can be used according to different use environment can be composite sandwich plate, stainless steel plate, cold rolled plate, stainless steel plate inlaid anti-corrosion wood, concrete wall, so as to achieve coordination with the environment.

(2) high-voltage chamber

High voltage inlet cabinet, high voltage outlet cabinet, high voltage metering cabinet, PT cabinet, DC screen and other devices are installed in European box transformer high voltage switchgear mainly to XGN15-12 type ring network cabinet and XGN-12 type inflatable cabinet, simple operation, safe use.

(3) Transformer room

European-style box transformer room is equipped with dry type transformer or oil-immersed transformer, temperature controller and high-power fan are installed indoors. The high-voltage end of transformer is connected by cable, the low-voltage end is connected by high-quality copper bar, and the exposed part is wrapped by insulating sleeve.

(4) low-voltage chamber

European-style box transformer low-voltage chamber mainly uses GGD low-voltage switchgear, according to the demand can be configured with low-voltage inlet line, low-voltage metering, low-voltage compensation, low-voltage outlet switchgear, can realize intelligent control, without special guard.

(5) Principle

The principle of European box-type substation is basically the same as that of traditional civil power room. The high-voltage power supply comes in through high-voltage switchgear, goes through transformer step-down, and then distributes electric energy through low-voltage switchgear. Because European box-type substation adopts box shell structure, it can be strong mobility, easy installation, and can be used outdoors.
