GGD-type low-voltage switch cabinet

Abstract

The invention discloses a GGD-type low-voltage switch cabinet, which comprises a cabinet body, wherein an activated carbon moisture absorption layer is arranged on the inner wall of the cabinet body; a rubber insulating layer is arranged on the lateral wall, far away from the cabinet body, of the activated carbon moisture absorption layer; dense moisture absorption holes are arranged in the rubber insulating layer; a beam is arranged at the upper end of the cabinet body; an intake fan is arranged at the upper end of the beam; the lower end of the intake fan is connected with a first intake pipe; and the first intake pipe is introduced into the cabinet body. The intake fan and an exhaust fan are arranged, so that the air liquidity in the cabinet body is strengthened; and the heat is not accumulated. When the heat cannot be timely conducted, a second intake pipe is opened and a condenser cools the air and then introduces the air into the cabinet body to cool the cabinet body, so that the problem of an electrical fire generated at a high temperature is solved. The activated carbon moisture absorption layer is arranged on the periphery in the cabinet body to absorb moisture, so that the cabinet body is always in a dry environment; and the problem of the fire generated by a short circuit caused by moisture condensation is solved.

AI Technical Summary

Problems solved by technology

[0003] However, when the GGD switchgear is used for a long time, electrical fires are prone to occur, which will cause a lot of property losses to the users. One of the reasons for the electrical fires is that a large amount of heat is generated when the electrical components in the cabinet are working. Conducted out of the cabinet in time, due to the accumulation of heat, the electrical components are prone to spontaneous combustion and cause a fire. Another reason is that the moisture inside the cabinet is accumulated and condensed due to the temperature difference between day and night and the change of its internal temperature. Causes a short circuit at the connection of electrical components and a fire
