Description

Assembled transformer substation complete machine structure

Technical Field

The invention relates to the technical field of power distribution equipment, in particular to a complete machine structure of an assembled transformer substation.

Background

The box-type transformer substation, called preassembled substation or preassembled substation, is a prefabricated indoor and outdoor compact type power distribution equipment of a factory, which is integrated by a certain wiring scheme, i.e. the functions of high-voltage power receiving, voltage reduction of the transformer, low-voltage power distribution and the like are organically combined together, and a novel transformer substation which is built up after the civil engineering of the substation is provided with a moisture-proof, rust-proof, dust-proof, rat-proof, fire-proof, anti-theft, heat-insulating, totally-enclosed and movable steel structure box body, and is mechanically and electrically integrated and operated in a totally-enclosed mode, and is particularly suitable for urban network construction and transformation.

At present, the box-type transformer substation is widely used due to small occupied area and low cost. In the field of power transformation and distribution, the cabin body is limited in the length direction and the width direction due to the limitation of transportation, but the arrangement size of a power distribution cabinet installed in the cabin often exceeds the limit transportation size of the cabin body, and the cabin body is subjected to sectional treatment and the whole cabin body is spliced on site.

After the existing transformer substation works for a long time, very high heat is generated in the box body, so that the temperature in the box body rises, a common heat dissipation mode is used for dissipating heat only through air holes or shutters on the outer wall of the box body, and in hot summer, air in the box body flows very weakly under the condition of very high external temperature, the temperature inside and outside the box body is very high, the heat dissipation effect is extremely poor, a large amount of heat generated after devices in the transformer substation work easily causes the condition that the transformer substation is powered off, and explosion can occur in severe cases. Moreover, environmental conditions around industrial and mining enterprises are mostly very severe, once a gate of an outdoor box-type transformer substation is opened, sand and dust easily enter the transformer substation, and potential safety hazards are brought to internal electrical equipment; on the other hand, the service life of the air conditioning system is reduced because the air conditioning system works continuously for 24 hours.

The outdoor box-type transformer substation and the outdoor steel structure house all adopt frame-type structures, namely the steel structure house is formed by assembling a base, a frame, an external wall board, an internal wall board, a ceiling board and a roof board, and due to the existence of the frame, some spliced parts of the wall board and the frame are sealed by means of sealant, or are spliced in a full welding mode, if the sealant is improperly smeared or the welded parts have the defects of cold welding and the like, poor sealing is caused, and a water leakage phenomenon is easy to occur, so that the operation safety of equipment in the box-type transformer substation is endangered.
