Power distribution cabinet with good heat dissipation effect

Abstract

The invention discloses a power distribution cabinet with a good heat dissipation effect. The cabinet comprises a power distribution cabinet, bases are fixedly connected to two sides of the bottom ofthe power distribution cabinet; a cavity is formed in the power distribution cabinet body, cooling fans are fixedly connected to the upper portion and the lower portion of one side of the inner wall of the power distribution cabinet, one sides of the two cooling fans penetrate through the power distribution cabinet and extend into the cavity, and fixing blocks are fixedly connected to the two sides of the inner wall of the power distribution cabinet and located between the two cooling fans. The invention relates to the power distribution cabinet technical field. In the power distribution cabinet, a sliding block is arranged on the outer surface of a sliding rail; a first limiting plate and a second limiting plate on the sliding block are matched to limit the variable-frequency product; andthe variable-frequency product can be clamped between the first limiting plate and the second limiting plate by utilizing the elasticity of the connecting spring, so that the fixed connection of thevariable-frequency product is prevented, the structure is simple, the device can adapt to products with different sizes, the installation is rapid, and special tools such as wrenches are not needed.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with good heat dissipation effect. Background technique [0002] 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 there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. Distribute the electric energy to the nearest load. This level of equipment should provide protection, monitoring and control for the load. Since the power distribution cabinet is equipped with a large number of power and communication equipment such as fuses, contactors, residual current action protectors, capacitance meters, Components such as circuit breakers, watt-hour meters, frequency converters, etc., these components will also generate a lot of heat whe...
