Product Description

Product Description

 

Box-type substations are suitable for residential areas, urban public substations, bustling downtowns, construction power supplies, etc. Users can choose box-type substations according to different usage conditions and load levels.

The box of the European substation is composed of three parts: base, shell and top cover. The base is generally made of channel steel, angle steel, flat steel, steel plates, etc., which are assembled and welded or connected and fixed with bolts; in order to meet the needs of ventilation, heat dissipation and incoming and outgoing lines, strip holes and moderately sized round holes should be opened at the corresponding positions. shaped hole. The box shell, top cover channel steel, angle steel, steel plate, aluminum alloy plate, color steel plate, cement board, etc. are bent, assembled and welded, or connected and formed with screws, hinges or related special accessories.

The structure of the high-voltage metering cabinet of a box-type substation is generally composed of: CT, PT, and meter, remote control, telemetry device, etc.

In European box transformers, the transformer can be either an oil-immersed transformer or a dry-type transformer. However, due to the higher price of dry-type transformers, if the user has no special requirements, the oil-immersed transformer should be preferred to reduce manufacturing costs. cost

The low-voltage room of the European box-type transformer should have different design structures according to the different use occasions in industrial and mining enterprises or residential areas. Generally, for European-style box-type transformers used by industrial and mining enterprises, power supply and lighting power supply should be designed separately.
