Insect-proof power distribution cabinet and use method thereof

Abstract

The invention relates to the technical field of power distribution cabinets, in particular to an insect-proof power distribution cabinet and a use method thereof. The insect-proof power distribution cabinet is characterized in that the side wall of a power distribution cabinet body is provided with an air inlet groove and a first filter screen, the inner wall of the power distribution cabinet body is fixedly provided with an air inlet box connected with the air inlet groove, the end, away from the first filter screen, of the air inlet box is opened for air exhaust, a plurality of filter screen plates are fixedly arranged in the air inlet box through limiting assemblies in the airflow direction, and an insect killing box communicating with the interior of the air inlet box is arranged at the bottom end of the air inlet box. According to the invention, a plurality of layers of filter screen plates are additionally arranged in the power distribution cabinet, and the filter screen plates can filter air gradually in the operation process so as to prevent filter screens from being blocked; and an insect killing medicine bag is additionally arranged in the insect killing box, so that insects can be effectively killed, damage of the insects to electric elements in the power distribution cabinet body is avoided, and operation stability of the power distribution cabinet is improved.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to an insect-proof power distribution cabinet and a method for using the same. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), metering cabinets (boxes), etc., which are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. [0003] The power distribution cabinet is mainly used in the occasions where the load is relatively scattered and there are few circuits; while the motor control center is mainly used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and contr...

AI Technical Summary

Problems solved by technology

[0005] However, when the door of the power distribution cabinet is kept open for heat dissipation, it is easy for insects to enter the cabinet. When insects enter the power distribution cabinet, it is easy to cause short-circuit damage to the internal circuit of the power distribution cabinet, affecting the safety of power supply, and even causing accidents in severe cases. The current solution is Add a filter in the air intake area, but a single-layer filter with too small spacing can easily block dust, easily lead to blockage of the filter holes, and strongly block the air flow rate. The heat dissipation effect inside the power distribution cabinet is not ideal, and the filter spacing When the size is too large, the anti-insect effect is not ideal, and the insects can still enter the power distribution cabinet and cause circuit damage
