Explosion-proof distribution cabinets are mainly used in hazardous places such as petrochemical facilities. To prevent the impact of harsh environments, they must not only have dustproof and waterproof functions but also acid and alkali resistance, with relatively high protection level requirements. The fundamental purpose of using explosion-proof distribution cabinets is to prevent explosions during the operation of electrical components, further improving operational safety.

Therefore, during use, it is necessary to start from the source to ensure the safety of the explosion-proof distribution box itself, perform daily maintenance and care of explosion-proof motors, and promptly resolve problems that may arise during use.。This enables the explosion-proof distribution box to fully exert its working effect and be better applied in flammable and explosive locations.。

Since the actual service environment of explosion-proof distribution boxes is extremely harsh, and outdoor-installed explosion-proof distribution boxes are exposed to sun and rain year-round, problems of inadequate sealing in explosion-proof distribution boxes are prone to occur.。

Once an explosion-proof distribution box has a sealing problem, it not only seriously affects the explosion-proof performance, but can also cause water ingress into the box, leading to short circuits in the internal wiring and tripping of circuit breakers.。

Generally, inadequate sealing of explosion-proof distribution boxes is mainly manifested in two aspects: insufficient sealing at the cable entry and exit points, and poor sealing between the box cover and the box body.。So how to solve the sealing problem?？

Explosion-proof distribution boxCabinet Body的AdvancedOutgoing Line Generally divided intoTop Inlet Top Outlet、Top Inlet Bottom Outlet And Bottom Inlet Bottom OutletThreeVariousform。They are generally composed of sealing rubber rings, metal rings, and compression nuts. Aging of the sealing rubber rings or loosening of the compression nuts can cause inadequate sealing of the explosion-proof distribution box. Especially for distribution boxes using the top-in top-out wiring method, once sealing is inadequate, flammable gases or rainwater can easily enter the box body.。
