Problems solved by technology

However, due to the configuration of many switches and instruments in the dust-proof switch cabinet, the heat emitted is relatively large. Therefore, a good heat dissipation effect is required, and in order to ensure the service life of electrical components, a better dust-proof effect is required.

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 , 2 As shown, the present invention is a dust-proof switchgear, including a dust-proof switchgear cabinet 1 and a three-phase electrical device composed of a disconnector, a circuit breaker and a grounding switch, which are arranged in the dust-proof switchgear cabinet 1. The dust-proof switch cabinet body 1 described above is provided with a side-by-side door 2 , and a ventilation hole 3 is arranged above the side-by-side door 2 . The ventilation holes 3 are strip-shaped holes, and a plurality of ventilation holes 3 are arranged in four rows.

[0018] Further, a dust-proof net 4 is provided inside the dust-proof switch cabinet body 1 provided with ventilation holes 3, and the dust-proof net 4 and the dust-proof switch cabinet body 1 are fixed by screws.

[0019] Preferably, a plurality of ventilation holes 3 are provided on the back of the...

Abstract

The invention provides a dust-proof switch cabinet which comprises a dust-proof switch cabinet body and three-phase electrical equipment which is arranged in the dust-proof switch cabinet body and consists of a disconnecting switch, a circuit breaker and an earthing switch, wherein a hinged door is arranged on the front of the dust-proof switch cabinet body; air holes are formed above the hinged door; and a dust screen is arranged above the hinged door. The switch cabinet has the beneficial effects that the switch cabinet is good in heat-dissipation effect, simple in structure, convenient to maintain, low in processing cost and good in dust-proof effect.

Description

technical field [0001] The invention belongs to the field of electromechanical auxiliary equipment, in particular to a dust-proof switch cabinet. Background technique [0002] The dust-proof switch cabinet is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., some also have high-voltage room and low-voltage room dust-proof switchgear, with high-voltage bus, such as power plants, etc., and some are also equipped with protection for main equipment. Low cycle load shedding. However, due to the configuration of many switches and instruments in the dust-proof switchgear, the heat emitted is relatively large. Therefore, a good heat dissipation effect is required, and in order to ensure the service life of electrical components, a better dust-proof effect...
