Description

Technical Field

Background

The prefabricated substation realizes electrical connection through a cable or a bus, all high-low voltage distribution devices and transformers are conventional shaped products, and the prefabricated substation has the advantages of small volume, small occupied area, light weight, low manufacturing cost and reliability, and is called a box-type substation or a prefabricated substation. The high-voltage switch equipment, the distribution transformer and the low-voltage distribution device are factory prefabricated indoor and outdoor compact distribution equipment which are integrated according to a certain wiring scheme, namely, the functions of transformer voltage reduction, low-voltage distribution and the like are organically combined together and are arranged in a steel structure box which is damp-proof, rust-proof, dust-proof, rat-proof, fireproof, anti-theft, heat-insulating, totally-closed and movable. The box-type transformer substation is suitable for mines, factory enterprises, oil-gas fields and wind power stations, replaces the original civil power distribution room and power distribution station, and becomes a novel complete set of power transformation and distribution device.

For a box-type substation, the box-type substation introduced and imitated from the countries of France, Germany and the like in the later 70 th century of China adopts a high-voltage and low-voltage switch cabinet and a transformer composition mode from the structure, the box-type substation is called as an European box-type substation, and is different from the European box-type substation, and the American box-type substation has the defects that as a load switch is immersed in oil, the oil is carbonized and decomposed by electric arc, harmful gases such as acetylene and the like are generated, so that the performance is reduced, and accidents occur once; the obvious disconnection point cannot be seen, the overhaul is inconvenient, because the American low-voltage protection and metering mode is different from that of China, and the American box transformer substation does not have the low-voltage protection and metering. Because the box-type variable-length case is under the direct sun of the sun, the heat dissipation of the molded case circuit breaker is influenced, the circuit breaker can not normally cut off load and short-circuit current, high-voltage side faults are easily caused, and compared with an European case transformer with the same capacity, the American case transformer is more reasonable in structure. Because the European box transformer is formed by arranging the transformer and common high-voltage electrical equipment in the same metal shell box body, the temperature of the transformer is very high, so that the heat dissipation is difficult, the normal working load of the transformer is seriously interfered, and the service life of the transformer is shortened.
