Novel safety power distribution cabinet and use method thereof

Abstract

The invention discloses a novel safety power distribution cabinet which comprises the components of a main body unit which comprises a cabinet body, an upper sealing cabinet door and a lower sealing cabinet door which are arranged at one side of the cabinet body, and a flame-retardant thermal baffle which is arranged at the inner side of the cabinet body, and two sides of the cabinet body are provided with strip-shaped ventilation openings; the carbon dioxide gas storage unit comprises storage tanks symmetrically arranged on the flame-retardant heat insulation plate and a communicating pipe connected with the storage tanks, and the communicating pipe is of an L-shaped structure; and the driving unit comprises a gear motor arranged on the top wall of the cabinet body and a screw rod arranged at the output end of the gear motor. The working state of the power distribution cabinet is reasonably sensed through the temperature control switch, when the temperature abnormally rises, the driving unit and the carbon dioxide gas storage unit rapidly correspond to each other, and the gear motor indirectly controls the control valve to be opened, so that carbon dioxide gas is rapidly released, and a fire is timely extinguished.

Description

technical field [0001] The invention relates to the technical field of power distribution, in particular to a novel safety power distribution cabinet and a method for using the same. Background technique [0002] The power distribution cabinet is the final equipment of the power distribution system. The power distribution cabinet is a general term for 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. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. . [0003] In the power distribution cabinet, because the instruments and electrical components are fixed in the box through the mounting plate and bolts, the ar...

AI Technical Summary

Problems solved by technology

[0003] In the power distribution cabinet, because the instruments and electrical components are fixed in the box through the mounting plate and bolts, the arrangement of the instruments and electrical components is relatively concentrated. In order to meet the heat dissipation requirements of the power distribution cabinet, a certain number of cooling holes are required in the cabinet. However, due to the aging of electrical components and lines, a fire occurs in the power distribution cabinet. In the case of better ventilation, it will help the further spread of the fire and greatly reduce the safety of the power distribution cabinet. We propose a new type of safety distribution cabinet and its use method to solve the above problems
