Outdoor waterproof and dustproof switch cabinet

Abstract

The invention discloses an outdoor waterproof and dustproof switch cabinet, which comprises a cabinet body, wherein supporting legs are arranged at the bottom end of the cabinet body, a switch opening is formed in one side of the cabinet body, a switch door is arranged at the switch opening, the switch door is hinged to the cabinet body, a plurality of ventilation openings are formed in side walls at two ends of the cabinet body, a matching groove is formed in the middle of the switch door, a sealing ring is arranged in the matching groove and makes contact with the side edge of the matching groove, a sealing plate is arranged in the cabinet body along the side wall of the switch opening, the cross section of the sealing plate is in an L shape, and the sealing plate and the side wall of the switch opening define a sealing cavity used for containing a sealing ring. According to the scheme, through the arrangement of the matching groove in the middle of the switch door and the sealing ring in the matching groove, the sealing plate at the switch opening can be matched to seal the position of the switch opening, so that external rainwater is prevented from permeating into the switch cabinet through a gap, the moisture-proof performance is ensured, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of power control equipment, in particular to an outdoor waterproof and dustproof switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the touch switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. [0003] When the existing switchgear is used outdoors, when encountering rainy weather, the external rainwater easily enters the inside of the switchgear, causing humid gas to be generated in the switchgear, which affects the normal use of the switchgear. In addition, in windy weather, the switchgear The air intake from the vent will directly blow the internal connectors, affecting the power connection effect. At the same time, the dust carried can easily affect the normal ...

Problems solved by technology

[0003] When the existing switchgear is used outdoors, when encountering rainy weather, the external rainwater easily enters the inside of the switchgear, causing humid gas to be generated in the switchgear, which affects the normal use of the switchgear. In addition, in windy weather, the switchgear The air intake from the vent will directly blow the internal connectors, which will affect the power connection effect. At the same time, the dust carried will easily affect the normal use of internal components and affect the service life of the switchgear.
