Abstract

The invention discloses a power distribution box with a novel shell structure and belongs to the electric power technical field. The power distribution box with the novel shell structure comprises a frame; the frame is made of an integrated high-strength glass fiber reinforced plastic material; and an electromagnetic shielding layer, a heat insulating layer, an insulating layer and a fireproof layer are arranged in the frame. With the power distribution box with the novel shell structure provided by the above technical scheme adopted, the problems of high possibility of being etched, in capability of shielding interferences of external environment and electromagnetic environment on an intelligent control device exiting on the shell of a traditional power distribution box can be solved, and a power source can be cut off timely when a short-circuit fire occurs, and personnel security can be ensured.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a distribution box with a novel shell structure. Background technique [0002] The traditional distribution box is made of metal material, and the outer layer of the metal material is coated with anti-corrosion materials for anti-corrosion. Since the control device of the power line is installed in the distribution box, it is often used during the switching process of the circuit. Discharge occurs, which requires the distribution box to have good insulation performance, and the circuit can be cut off in time when a fire occurs in the distribution box to ensure the safety of firefighters. [0003] With the upgrading of intelligent circuits, the control equipment in the distribution box tends to be more sophisticated and integrated. The problem that follows is that these integrated and sophisticated control devices are prone to electromagnetic interference and in...
