However, in occasions with high requirements for the working environment, the power distribution cabinet made of traditional metal plates cannot shield strong electromagnetic interference, which affects the work of precision power equipment installed inside; in high-temperature environments, traditional metal plates conduct heat Fast, the temperature of the cabinet body rises rapidly, affecting the normal operation of power equipment
In addition, when a fire breaks out in the cabinet, the existing power distribution cabinet cannot be effectively flame-retardant, which will easily lead to the spread of the fire source, resulting in increased losses

Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] Such as figure 1 As shown, the present invention is used for the panel of the cabinet body and cabinet door of the power distribution cabinet, including the interlayer 1, and the interlayer 1 adopts conventional metal materials. Inside the interlayer 1, a shielding layer 2 and an insulating layer 3 are arranged from outside to inside. The shielding layer 2 adopts an electromagnetic shielding film, which can prevent the strong electromagnetic interference in the working environment on the precision power equipment in the cabinet. The shielding layer 2 can also choose different shielding materials according to different interferences.
[0015] The insulation layer 3 is arranged on the inner side of the shielding layer 2, and the insulation layer 3 can slow down the introduction of the outdoors into the cabinet by the interlayer 1. The thermal insulati...

The invention discloses a plate applied to a cabinet body and a cabinet door of a power distribution cabinet, and belongs to the field of power equipment. The plate comprises an interlayer, wherein the interlayer is provided with a shielding layer and a heat preservation layer from outside to inside, and a fireproof layer is arranged on the inner layer of the interlayer. The shielding layer is arranged in a traditional interlayer to avoid influences of electromagnetism on precise electric equipment in the power distribution cabinet in a strong electromagnetic environment and guarantee normal operation of the precise electric equipment. The heat preservation layer is arranged on the inner layer of the shielding layer, can slow down conduction of high temperature outside the cabinet body to the cabinet body by the plate and keeps the temperature of the cabinet body normal and stable; the fireproof layer arranged on the inner side of the interlayer can prevent spreading of a fire disaster happening in the cabinet body. The invention further discloses the power distribution cabinet adopting the plate.
Description
technical field [0001] The invention relates to a board for a cabinet body and a cabinet door, in particular to a board for a cabinet body and a door of a power distribution cabinet and a power distribution cabinet, belonging to the field of electric equipment. Background technique [0002] The power distribution cabinet is a common electrical equipment, usually set in the grid terminal or factory workshop. The existing cabinet body and cabinet door of the power distribution cabinet are usually made of sheet metal, which can be widely used in different environments such as outdoors and workshops. However, in occasions with high requirements for the working environment, the power distribution cabinet made of traditional metal plates cannot shield strong electromagnetic interference, which affects the work of precision power equipment installed inside; in high-temperature environments, traditional metal plates conduct heat Fast, the temperature of the cabinet body rises r...
