Description

A power distribution cabinet for a power system

technical field

The utility model belongs to the technical field of power distribution cabinets, in particular to a power distribution cabinet for power systems.

Background technique

The power distribution cabinet is an important device in the power system. It is the general name of the motor control center. Its function is to distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby charges, and to protect, monitor and control the charges.

There are generally many electrical components installed in the power cabinet. When these electrical components run for a long time and generate high temperature, especially in summer, the temperature of these electrical components rises faster. At this time, it is necessary to cool down the electrical components in the power cabinet. Currently, The heat dissipation structure of the power cabinet is generally air-cooled by a fan installed in the inner cavity of the power cabinet. Due to the lack of a guide structure for the airflow, it is easy to cause the airflow to spiral and accumulate in the inner cavity of the power cabinet. This traditional air-cooled structure has a lower cooling effect. Not obvious, the air-cooled structure of a single fan is easy to accumulate heat in the power cabinet, but cannot effectively discharge the heat in time, reducing the service life of its electrical components.
