Auxiliary heat dissipation device for ring main unit

Abstract

The invention discloses an auxiliary heat dissipation device for a ring main unit, and the device comprises a box body which is provided with an opening, wherein the opening part is hinged with a boxdoor, and the box door is flush with the outer side wall of the box body after being closed; a fan assembly arranged along the inner side wall of the box body, wherein the fan assembly comprises a plurality of fan blades capable of revolving; a cooling assembly arranged in the inner cavity of the box body and comprising a plurality of cooling fins, wherein the cooling fins are arranged along the outline of the inner side wall of the box body, and the cooling fins form a U-shaped cooling fin module; and a driving module arranged in the inner cavity of the box body and used for driving the fan blades to rotate. The fan assembly is arranged, the fan blades can revolve around the central axis of the outer ring while rotating, it is guaranteed that in the heat dissipation process, the blowing area of the fan blades can cover the side face of the ring main unit, and the cooling and heat dissipation speed is increased; when rapid cooling is needed, cooling liquid is provided for the cooling pipe through the external container, the heat conduction area is increased by arranging the multiple sets of cooling fins, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a ring network cabinet, in particular to an auxiliary cooling device for a ring network cabinet. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has a structure Simple, small size, low price, can improve power supply parameters and performance, and power supply security and other advantages. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. When the ring network cabinet is working, once the internal temperature is too high, it is very easy to cause a short circuit and cause a fire. The inventors found tha...

AI Technical Summary

Problems solved by technology

When the ring network cabinet is working, once the internal temperature is too high, it is easy to cause a short circuit and cause a fire.

The inventors found that the existing ring network cabinets have the following defects: the heat dissipation effect of the ring network cabinet equipment is average, the internal heat cannot be dissipated efficiently, and the demand for rapid heat dissipation of the equipment cannot be met
