Submersible or buried box type high-voltage power transformer equipment

Abstract

The invention discloses submersible or buried box type high-voltage power transformer equipment, which comprises a box body and high-voltage power transformer equipment built in the box body, wherein the box body has an all-welded closed structure; the side wall of the box body is provided with an inlet cable and an outlet cable; connecting parts of the inlet cable and the outlet cable and the box body are sealed by seals; an air inlet pipe and an air outlet pipe penetrate the top of the box body in a sealing way; the parts of the air inlet pipe and the air outlet pipe extending into the box body have an altitude difference; a waterproof cap is arranged above the air inlet pipe and the air outlet pipe; and an antenna is erected above the waterproof cap. The box type power transformer equipment has simple structure and good sealing and cooling effects, does not occupy ground resources, can be widely applied to underground or underwater of various complex environments such as rivers, lakes, pits and the like, and can realize the remote control of the power transformer equipment in the box body through the antenna.

Description

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

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
