Heat-dissipation rain-proof power distribution cabinet

Abstract

The invention discloses a heat-dissipation rain-proof power distribution cabinet which comprises a cabinet body, a top cover and a cross-flow fan, wherein the cabinet body is connected with a cabinet door by a hinge; a transparency window is formed in the upper part of the cabinet door; the position of the transparency window is corresponding to that of a circuit breaker in the cabinet body; a self-locking handle connected with the cabinet body is arranged on the cabinet door; a slot is formed in one side of the bottom of the cabinet body; guide rails are arranged at the bottom of the slot; the cross-flow fan is arranged on the guide rails in a sliding manner; air inlets are formed in the right side of the cross-flow fan; fly nets are arranged in the air inlets in a welded manner; an air outlet is formed in the upper end of the cross-flow fan; the top cover is fixedly arranged on the cabinet body; and heat-dissipation fins formed through single-process punching are arranged on the top cover in a relatively inclined manner. The cabinet is provided with the cross-flow fan and is simple in structure; ventilating, water-proof, dust-proof and fly-proof functions of equipment are improved; automatic air supply for equipment cooling or dehumidification can be performed when a climatic condition and a ventilating condition are not ideal, so that normal operation of the equipment is guaranteed.

Description

technical field [0001] The invention relates to a power distribution cabinet, in particular to a heat dissipation and rainproof power distribution cabinet. Background technique [0002] With the continuous deepening of urban and rural power grid transformation, a large number of integrated distribution cabinets for distribution transformers have been used in rural power lines and distribution stations. The distribution transformer integrated distribution cabinet is designed to meet the requirements of standardization, miniaturization and outdoor type of rural low-voltage power distribution equipment. It integrates power distribution, measurement, protection and reactive power compensation of capacitors. A comprehensive power distribution cabinet for distribution transformers currently on the market includes a box body composed of a bottom plate, a side plate, a top plate and a sealing plate. Ventilation shutters are provided, heat absorbing fins and temperature controllers ...

AI Technical Summary

Problems solved by technology

The disadvantage of this kind of distribution transformer integrated distribution cabinet is that the heat dissipation and ventilation structure is complicated, and the processing process is cumbersome. In the case of unsatisfactory climate conditions and ventilation conditions, it cannot better dissipate heat and dehumidify, and has no dustproof and insectproof functions.
