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, and it is difficult to meet the ambient temperature requirements required for the normal operation of power equipment. Only for power transformers Generally, the method of reducing the capacity is adopted, which does not maximize the function of the equipment, and cannot effectively prevent rainwater and dust from entering the prefabricated substation box under harsh conditions such as storms and sandstorms, leaving behind the normal operation of power equipment.
