Chongqing high and low voltage integrated distribution cabinet quotation

box type substation. The products have the characteristics of strong completeness, small floor area, small investment, convenient installation and maintenance, beautiful appearance and strong weather resistance. It is a complete set of outdoor and oil transformation and distribution equipment composed of high-voltage switchgear, power transformer and low-voltage switchgear

the certification of environmental protection characteristics of dry-type transformer is very different from that of foreign and domestic: Based on the European standard HD464, the research and certification of climate resistance (C0, C1 and C2 confirm the composition conditions and law of - PbO2 oxide film), environmental resistance (E0, E1 and E2) and fire resistance (F0, F1 and F2) characteristics of dry-type transformer are carried out

the protection of box type transformer is specially designed to protect the transformer. It is a high-tech product of power automation integrating protection, monitoring, control, communication and other functions. It is an ideal electrical unit for intelligent box type transformer. The product has a built-in protection library composed of more than 20 standard protection programs, and has a complete and powerful collection function of voltage and current analog and switching value of primary equipment (current measurement is realized through protection CT), which is used to protect and enable it to operate normally and carry out safe production activities

box type substation can effectively prevent the invasion of small animals. The maintenance of the transformer is easily pushed and pulled out by a detachable trolley. Four corresponding lifting bolts that can be pulled out and pushed are set on both sides of the box base, and four supports with the same function are set on both sides of the roof eaves, which can be lifted and transported as a whole. This series of combined (box type) substation is a complete set of outdoor and oil transformation and distribution equipment composed of high-voltage switchgear, power transformer and low-voltage switchgear. The product has the characteristics of strong complete set, small floor area, small investment, convenient installation and maintenance, beautiful appearance and strong weather resistance

from the perspective of operation cost, it can be seen that even under the full load operation state, the box transformer consumes about 1 million kwh less electricity per year than the ordinary transformer, and the maintenance cost is less even in case of problems. Therefore, box type transformer has high application income

functional features of box transformer: This product is a frame structure, welded with section steel, covered with aluminum alloy plate and coated with special paint layer, so that it has strong mechanical properties, weather resistance and corrosion resistance. When the combined (box type) substation is an integral structure, the box is divided into three relatively independent chambers with steel plates, namely high-voltage chamber, transformer chamber and low-voltage chamber. The lighting of each room is automatically shut down with the opening of the door.? There is a thermal insulation layer on the top of the box type substation. In high temperature and cold areas, the temperature in the box is easy to accumulate and change and condense. The thermal insulation layer around the box can be added. In order to stabilize the temperature in the box, the transformer room and low-voltage room are equipped with automatic temperature control devices

service conditions of box type substation: the low voltage room is divided into two assembly forms: corridor type and non corridor type. Metering cabinet, main switch cabinet, outgoing cabinet, capacitor cabinet and contact cabinet (when there are two transformers) can be installed indoors, which has the overall function of low-voltage switchgear. The investigators did not rule out any possibility. Generally, the metering cabinet and the main switch cabinet are integrated, that is, the upper part of the cabinet is instrument, metering box, the middle and lower part is automatic air switch, lightning arrester and transformer. The capacitor cabinet can be manually and automatically controlled for automatic compensation. The capacitance reactive power compensation capacity is generally% of the transformer capacity, and the compensation capacity can also be increased or reduced according to the needs of customers
