Abstract

The invention provides a power distribution cabinet with internal cyclic heat dissipation. The power distribution cabinet comprises four semicircular-ring fixed frames, eight double-outlet-rod cylinders and the like, and is characterized in that the four semicircular-ring fixed frames are classified into two groups, each of which consisting of two semicircular-ring fixed frames, and the two groups are arrayed on upper and lower layers; the two groups of the semicircular-ring fixed frames on the upper and lower layers are connected together through four first electric cylinders; the rear end parts of the two semicircular-ring fixed frames in each group are hinged together; mounting holes for mounting bolts are formed in the front end parts of the semicircular-ring fixed frames; the two semicircular-ring fixed frames on the identical sides of the upper and lower layers are connected through two of the first electric cylinders; a damaged part of a power pole is repaired by adopting an external cement injection method, so that the service life of the power pole is prolonged.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to an internal circulation cooling power distribution cabinet. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is the general name of the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and the circuit is less. The traditional power distribution cabinet is only equipped with a cooling device on the box shell, which cannot dissipate heat well for the electrical equipment in the box. In the environment where the surrounding environment is too high, these electrical equipment are easily aged or damaged due to high temperature, so a A power distribution cabinet that can dissipate heat inside the cabinet.
