Abstract

The invention discloses an oil-immersed transformer capable of avoiding dust accumulation. The oil-immersed transformer comprises a transformer, an oil level indicator, a high-voltage wiring terminaland a low-voltage wiring terminal, a mounting base is arranged at the bottom of the transformer, an end cover is arranged above the transformer, the oil level indicator is mounted on the upper surfaceof the left side of the end cover, a rubber sealing ring is arranged on the upper surface of the end cover, an exhaust pipe is inlaid in front of a dustproof cover, a protective cover is installed onthe outer side of the dustproof cover through screws, a first filter screen is inlaid at the rear of the dustproof cover, a second filter screen is installed on the lower portion of the interior of an air inlet pipe, a main shaft penetrates the air inlet pipe, and a protective pipe is installed on the outer side of the air inlet pipe. The oil-immersed transformer capable of avoiding dust accumulation is provided with the dustproof cover and a rubber wiring pipe, a high-voltage wiring terminal and a low-voltage wiring terminal are sealed and protected through the design of the dustproof cover,dust is prevented from being accumulated on insulators on the outer sides of the high-voltage wiring terminal and the low-voltage wiring terminal, and the dustproof performance of the device is improved.

Description

technical field [0001] The invention relates to the technical field of oil-immersed transformers, in particular to an oil-immersed transformer that avoids dust accumulation. Background technique [0002] The oil-immersed transformer is a transformer in which the iron core and windings are immersed together in an oil tank filled with transformer oil. The transformer oil can effectively cool and cool the iron core and windings, increasing the practicability of the device. Oil-immersed The transformer is connected to the external power grid through the high-voltage terminal and the low-voltage terminal. However, there are still certain problems in the existing oil-immersed transformer; [0003] The high-voltage terminals and low-voltage terminals above the existing oil-immersed transformer are exposed to the air. When there is a lot of dust in the air, the dust will accumulate on the insulators of the high-voltage terminals and low-voltage terminals, thus affecting the device. ...
