Rain-proof, dust-proof and ventilated heat dissipation device of preassembled substation box

Abstract

The invention provides a rain-proof, dust-proof and ventilated heat dissipation device of a preassembled substation box, which is characterized by comprising a ventilated heat dissipation device and a dust filtering device, wherein the ventilated heat dissipation device is arranged at the outer side of a door plate of the preassembled substation box, and the dust filtering device is arranged at the inner side of the door plate of the preassembled substation box; the ventilated heat dissipation device comprises a frame and a bent plate which is arranged in the frame and is oblique and downward; the dust filtering device comprises a filtering screen bracket and a filtering screen which is arranged in the filtering screen bracket; and the frame, the door plate and the filtering screen bracket are connected through screws and fasteners. The device provided by the invention has the advantages of novel principle, simple structure, high generalization degree, high production efficiency, scientific and reasonable structure and good ventilated heat dissipation and dust-proof effects, is suitable for batch production, is convenient to assemble, and better achieves the purposes of ventilated heat dissipation, dust prevention and protection.

Description

technical field [0001] The invention relates to a rainproof, dustproof, ventilation and heat dissipation device for a prefabricated substation box body, which is used for ventilation and heat dissipation in a functional room (such as a transformer room) with a large calorific value in the box body during the use of prefabricated substation products The invention belongs to the technical field of ventilation and heat dissipation of prefabricated transformer substation boxes. Background technique [0002] Prefabricated substation products are substations that integrate high-voltage and low-voltage switchgear, power transformers, and many other power equipment. Because of their advantages such as small footprint, low investment cost, high integration, and flexible solutions, they are widely used in power systems. be more and more widely used.

Problems solved by technology

[0003] In prefabricated substation products, it has always been important to effectively dissipate the heat of main power components such as power equipment (such as primary power switchgear, power transformers, etc.) assembled in it from the box of prefabricated substation products to the outside. A difficult point in its manufacturing process is generally to use the method of opening ventilation holes on the box body. The ventilation volume and heat dissipation effect are generally limited, an
