Outdoor box-type 10-20kV/220V transformer

Abstract

The invention relates to an outdoor box-type 10-20kV / 220V transformer, which comprises a high-voltage insulation sleeve, a metal box body, a transformer body, a secondary winding outgoing wiring board of the transformer, and installation channel steel, wherein the high-voltage insulation sleeve penetrates through the upper end surface of the metal box body to be fixed, and a certain spatial distance between the transformer body and the metal box body is kept; and the secondary winding outgoing wiring board of the transformer is arranged at the outer side of the lower end of one side of the metal box body, and the transformer body and the metal box body are arranged on the channel steel. The outdoor box-type 10-20kV / 220V transformer is developed to be used for distribution lines, transformer on-site intelligent control, protection devices and on-off of a power supply of an automatic operating mechanism according to the practical need of a power distribution network site, overcomes the defects that oil is leaked in an oil-immersed transformer and an epoxy resin cast transformer is aged and cracked due to the exposure to the weather, and has the advantages that: the safe operation of a power distribution system can be improved, the reliability of power supply is improved, the damage to the transformer is reduced, the amount of power supply is increased, and the enterprise and social benefits are increased.

Description

technical field [0001] The invention relates to an outdoor box-type 10-20kV / 220V transformer, which is a power supply applied to distribution network lines, on-site intelligent control of transformers, protection devices and automatic switch operation mechanisms.

Problems solved by technology

The power of the power grid is transformed and delivered to thousands of households through the distribution network and distribution transformers. The current operating distribution network lines, on-site intelligent control of transformers, protection devices and automatic switch operation mechanism power supplies use oil-immersed transformers. , Epoxy resin casting type; the disadvantage of oil-immersed transformer is that it is easy to leak oil, insulation is difficult to guarantee, and often fails; the disadvantage of epoxy resin casting type transformer is that epoxy resin is easy to age and crack when exposed to wind and sun, causing power outages ACCIDENT
