A thermally insulated electric device dedicated to the outdoors

Abstract

The invention relates to special outdoor thermal insulation electrical equipment. The special outdoor thermal insulation electrical equipment comprises a transformer and a power distribution cabinet, wherein the transformer comprises a transformer box body, a transformer box cover, an iron core and a coil winding; the coil winding is wound around the iron core in a wrapping manner; the iron core and the coil winding are both arranged in the transformer box body; the transformer box body is filled with transformer oil; a conservator is arranged on the transformer box cover; a thermal insulation plate is arranged on the inner surface of the cabinet body of the power distribution cabinet; the transformer box cover is fastened on the transformer box body through fastening bolts; an alarm protection structure is arranged between the transformer box cover and the transformer box body; a sealing rubber mat is also arranged between the transformer box cover and the transformer box body; high-voltage wire-outlet sleeve pipes and low-voltage wire-outlet sleeve pipes are also arranged on the transformer box cover; main radiating pipes are arranged on the front and back sides of the transformer box body; auxiliary radiating structures are arranged on the left and right sides of the transformer box body; an anti-theft oil drain valve is arranged at the bottom of the transformer box body; and the transformer also comprises a high-voltage wiring structure, a low-voltage wiring structure and a wire-breaking detection apparatus.

Description

technical field [0001] The invention belongs to the technical field of power systems, and relates to heat-insulating power equipment specially used for outdoors. Background technique [0002] As a kind of power equipment used in the power system, the transformer is an indispensable element in the entire power grid transmission process, and plays a decisive role in the normal operation of the power grid. [0003] With the continuous progress of economic development, power grid construction is spread all over the country; more and more outdoor transformers are installed due to the needs of power grid construction. [0004] Although the installation of outdoor transformers can reduce the cost of grid construction and effectively improve the transmission performance of the grid; however, outdoor transformers are prone to the following problems due to their long-term exposure to the open air: [0005] First, outdoor transformers are very prone to transformer oil leakage due to t...

AI Technical Summary

Problems solved by technology

[0005] First, outdoor transformers are prone to transformer oil leakage due to their long-term exposure to the open air; oil leakage in a single transformer will inevitably lead to a sharp reduction in its own service life, which will eventually affect the normal transmission of power

[0006] Second, outdoor transformers in summer are exposed to the scorching sun for a long time, which not only easily causes damage to the transformer, but also reduces the normal heat dissipation of the transformer oil.

[0007] Third, once the outdoor transformer oil conservator in the prior art explodes, the hot oil in the oil conservator will splash everywhere, which can easily cause surrounding fires

[0008] In addition, outdoor transformers are usually equipped with outdoor power distribution cabinets, and outdoor power distribution cabinets are exposed to sunlight for a long time, causing the internal temperature to be too high, which affects the normal use of internal power components.
