(Summary description)According to the structure of box-type substation, manufacturers of box-type substation mainly include American box-type substation and European-type box-type substation. European-style box-type substations are low in cost, and American box-type substations are small in size, about 1.3-1.5 of that of European-style box-type substations with the same capacity. The traditional civil substation covers the largest area, followed by the European-style box-type substation.

1. Box-type substation manufacturer-determination of box structure
According to the structure of box-type substation, manufacturers of box-type substation mainly include American box-type substation and European-type box-type substation. European-style box-type substations are low in cost, and American box-type substations are small in size, about 1.3-1.5 of that of European-style box-type substations with the same capacity. The traditional civil substation covers the largest area, followed by the European-style box-type substation. The U.S. box-type substation has the longest construction period, while the European-style box-type substation ranks second. Considering the general 35kv box-type substation box, choose the European-style box-type substation. The following box-type substation manufacturers mainly introduce 35kv box-type substation box options and equipment configuration schemes
⒉Box-type substation manufacturers-reasonable configuration
Box-type substation manufacturers can adopt different configuration schemes of box-type transformers according to the actual situation. Generally speaking, the main transformer, power capacitors and other oil filling facilities are placed outside the box, and 2 boxes, 1 35k box and 1 10k box are set up, one of which is 1 box. The seat of the protective device was left in the body. Taking into account the cost savings, you can only place the 10kv standard machine on the outdoor 35kv circuit breaker and other facilities.
Box-type substation manufacturers: The box-shaped bottom bracket and structure are generally made of steel and angle steel by electric welding, and the cover and wall cover are restrained by the metal material plate with fireproof material, which has the effect of heat insulation. According to the actual situation, it can point out the corresponding requirements of the main structure when purchasing. For example, some areas are located in the saline-alkaline soil zone, requiring facilities with high corrosion resistance. For this reason, in addition to the anti-rust treatment of the main box frame, 0.5mm thick stainless steel plate is also used for the overall outer partition of the box.
Maintenance channels are an important part of the normal operation and maintenance of box-type substations. One of the disadvantages of box-type substations is that the space is small. Manufacturers usually try to minimize equipment costs and compact maintenance channels. When selecting modeling, the maintenance of the safe passage should be regarded as a technical indicator, otherwise it will cause many problems to the subsequent use and maintenance.
The airtightness and anti-fouling of the box are critical aspects, especially the protective device has a high demand for anti-fouling and other technical indicators, which should be paid attention to.
The bottom of the box type is mostly used for the cable room. When considering the foundation of the box type, the convenience of cable assembly and maintenance should be considered, and the needs of technical personnel, natural ventilation and lighting should be considered.
