Integral-type underground high-voltage transformation equipment

Abstract

The invention discloses integral-type underground high-voltage transformation equipment, comprising a box body and high-voltage transformation equipment arranged in the box body, wherein, the box body arranged in a overall cement pond, the top of the cement pond is covered by a precast cement slab which is provided with a lifting groove, the box body is of an all-welded closed structure, the side wall of the box body is provided with an incoming cable and an outgoing cable, the joint of the incoming cable and the outgoing cable and the box body is sealed through sealing parts, the top of the box body is provided with an air inlet pipe and an air outlet pipe in a sealing way, the parts of the air inlet pipe and the air outlet pipe which enter the box body have altitude difference, a waterproof cap is arranged above the air inlet pipe and the air outlet pipe, and an antenna is arranged above the waterproof cap; the advantages of the invention are as follows: the invention with simple structure, good sealing and cooling effect not only can be used underground or underwater, such as rivers, lakes, ponding and other complex environments, but also can be used for remotely controlling the transformation equipment in the box body through the antenna, and does not occupy ground resources.

Description

technical field [0001] The invention relates to a box-type high-voltage substation equipment, in particular to an integral high-voltage substation equipment that can be buried underwater or underground. Background technique [0002] Existing high-voltage substation equipment such as substations or combined transformers are usually built on the ground, which is easily damaged and occupies ground resources, which not only affects the walking of vehicles or people, but also hinders the beauty of the environment. There is also a kind of substation equipment installed underground or semi-underground, but its heat dissipation structure design is complicated, and an external radiator is required for heat dissipation, or a heat dissipation air passage needs to be left on the ground surface, and the heat dissipation air passage is easy to enter rainwater or be blocked by road dirt Therefore, it cannot effectively solve the heat dissipation problem of underground substation equipment;...

Problems solved by technology

[0002] Existing high-voltage substation equipment such as substations or combined transformers are usually built on the ground, which is easily damaged and occupies ground resources, which not only affects the walking of vehicles or people, but also hinders the beauty of the environment

There is also a kind of substation equipment installed underground or semi-underground, but its heat dissipation structure design is complicated, and an external radiator is required for heat dissipation, or a heat dissipation air passage needs to be left on the ground surface, and the heat dissipation air passage is easy to enter rainwater or be blocked by road dirt Therefore, it cannot effectively solve the heat dissipation problem of underground substation equipment; at the same time, the design of its box structure cannot solve the problem of sealing and water isolation of the box well, so it cannot be applied to rivers, rivers, and lakes. In various complex environments such as low-lying areas, depressions, etc., especially in the south, there are many intrusions by rainwater and floods, and the moisture-proof and waterproof performance of underground high-voltage substation equipment is also relatively high; in addition, the existing underground high-voltage substation equipment is structurally designed. There are defects, and once a fault occurs, it is impossible to enter the box for repairs
