Abstract

The invention belongs to the field of distribution equipment, and discloses a closed low-voltage distribution box. The closed low-voltage distribution box comprises a box body which is prepared according to the following process: step 1) preparation of a component A; step 2) preparation of a component B; step 3) preparation of a component C; and step 4) preparation of the box body. The distribution box provided by the invention has the advantages of large mechanical strength, corrosion resistance and good flame retardant performance.

Description

technical field [0001] The invention belongs to the field of power distribution equipment, in particular to a closed low-voltage distribution box. Background technique [0002] The closed low-voltage distribution box is a large number of parameters in the data. Generally, the low-voltage forest is composed of electrical wiring. It is required to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed metal cabinet to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. The distribution box is used to distribute electric energy reasonably and facilitate the opening and closing operation of the circuit. It has a high level of safety protection and can intuitively display the conduction state of the circuit. Most of the existing closed low-voltage distribution boxes are made of metal, and the exterior is painted. The large-scale distrib...
