Description

A self-dusting high and low voltage power distribution cabinet and dust removal method

technical field

The invention relates to the technical field of power distribution cabinets, in particular to a self-dusting high and low voltage power distribution cabinet, and also relates to a method for using the self-dusting high and low voltage power distribution cabinet.

Background technique

Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in places where the load is relatively scattered and there are few circuits; the motor control center is used in places 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 control of the load. However, the existing dust removal mechanism of the power distribution cabinet cannot guarantee that the dust in the cabinet can be minimized all the time.

Chinese Patent No. CN110911976A discloses an internal dust removal mechanism for power distribution cabinets. The device drives the fan blades to blow toward the inside of the power distribution cabinet through a motor, so that the dust inside the power distribution cabinet is raised, and then the exhaust fan sucks the dust-carrying air into the dust collection box, thereby realizing the dust removal function in the power distribution cabinet.

However, in the actual operation process, the dust in the power distribution cabinet is blown up by the fan blades driven by the motor and then drawn out by the exhaust fan, which will cause a large amount of dust to adhere to the inner wall of the power distribution cabinet. In the long run, it will lead to poor ventilation of the power distribution cabinet.
