High-heat-dissipation modular transformer substation box body

Abstract

The invention discloses a high-heat-dissipation modular transformer substation box. The transformer substation box comprises a box body, wherein a first water tank is arranged on a lower side of the box body, the box body is supported through supporting columns arranged in a rectangular mode, a temperature sensor is arranged in the box body, the first water tank is connected with a water inlet pipe, a submersible pump and an electronic liquid level meter are arranged in the first water tank, and the submersible pump is connected with a second water tank through pipelines; the second water tankis located at the upper side of the middle part of the box body, and a vertical upward ventilation pipe is arranged in the second water tank, and an upper end of the ventilation pipe runs through thesecond water tank. The ventilation area of the lower side is changed through the shaking plates on the two sides so as to adapt to different heat dissipation effects, water is spread through step plates, the inclined plates and the water absorption layers on the shaking plates, the evaporation area of the water is increased; heat transfer efficiency is improved, and then the local temperature ischanged, the upper side of a semiconductor chilling plate generates heat, a lower side of the semiconductor chilling plate refrigerates, and hot air rises, so the negative pressure is formed in the vent pipe to form air flow, and the lower side of the semiconductor chilling plate refrigerates and enters the box body through airflow and the fan.

[0002] Box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme. It is about high-voltage power receiving, transformer step-down, low-voltage distribution Electricity and other functions are organically combined and installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box, mechanical and electrical integration, fully enclosed operation, especially It is suitable for the construction and transformation of the urban network. It is a brand-new substation emerging after the civil substation. It replaces the original civil construction power distribution room and distribution station, and becomes a new type of complete power transformation and distribution device. The box-type substation is suitable for Residential districts, urban public substations, bustling downtown, construction power supply, etc., the existing box-type substations will generate a lot of heat due to working under high voltage conditions, and the heat dissipation conditions are poor, and often stop working due to high temperature damage to the substation
