Protective device for outdoor transformer

Abstract

The invention relates to a protective device for an outdoor transformer. The protective device comprises a transformer box and a transformer box cover; transformer oil is filled in the transformer box; an oil conservator is arranged on the transformer box cover; the transformer box cover is fastened on the transformer box through an anti-theft bolt; an alarm protective structure is arranged between the transformer box cover and the transformer box; a sealing rubber gasket is also arranged between the transformer box cover and the transformer box; a high-voltage lead-out bushing and a low-voltage lead-out bushing are also arranged on the transformer box cover; a main heat dissipation pipe is arranged at the front and rear sides of the transformer box; an auxiliary heat dissipation structure is arranged at the left and right sides of the transformer box; an anti-theft oil drain valve is arranged at the bottom end of the side wall of the transformer box; a buffer shock absorption structure is arranged at the bottom of the transformer box; the transformer further comprises a high-voltage wiring structure and a low-voltage wiring structure; and the transformer further comprises a line disconnection detection device.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and relates to equipment for an outdoor power system, in particular to a protection device for an outdoor transformer. Background technique [0002] As a distribution and transformation 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 power grid construction and effectively improve the power transmission performance of the power grid; however, due to the expensive parts of outdoor transformers, there is a major hidden danger of being stolen. Once ...

[0004] Although the installation of outdoor transformers can reduce the cost of power grid construction and effectively improve the power transmission performance of the power grid; however, due to the expensive parts of outdoor transformers, there is a major hidden danger of being stolen. Once the outdoor transformer is stolen, it will inevitably affect the normal operation of the entire power grid. operation, the loss to economic development and residents' life is immeasurable. In addition, one

[0005] Second, outdoor transformers are very 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] Third, 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] Its four, once the outdoor transformer oil conservator in the prior art explodes, the hot oil in the oil conservator is caused to splash everywhere, which can easily cause surrounding fires
