Description

A dustproof high and low voltage switch cabinet

Technical Field

The utility model relates to the field of electrical equipment, in particular to a dustproof high and low voltage switch cabinet.

Background Art

As the name suggests, high and low voltage switchgear is equipment for connecting high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. The low-voltage cabinets are then transferred to distribution boxes for various electricity users. What is inside is nothing more than some protective devices such as switches and circuit breakers assembled into one electrical equipment.

In order to prevent dust from entering the cabinet along with the air, most of the existing switch cabinets will choose to install dust screens on the side with screws or bolts. However, this installation method is not convenient for disassembly, resulting in dust accumulation on the surface of the dust screen if it is not cleaned for a long time. The filter holes are blocked by dust, which will affect the normal ventilation of the switch cabinet and make the internal electrical components unable to dissipate heat normally. Therefore, in view of the above problems, a dustproof high and low voltage switch cabinet is proposed.
