Problems solved by technology

[0003] In an environment with high temperature, excessive heat generation of electrical components may cause fire, and it is necessary to use fire extinguishers in time to extinguish the fire. However, due to the wide distribution of power cabinets, it is difficult for personnel to detect and extinguish the fire in time, which brings more serious problems. Big security risks, but also cause certain property losses

Abstract

The invention discloses a power cabinet with a fire extinguishing function, comprising a cabinet body, an electromagnet, a sleeve, a first movable rod, a second movable rod, a first wedging block, a second wedging block, a fixed plate, and a guide column and movable plate; when a fire occurs inside the cabinet, the electromagnet is energized through the action of the temperature sensor and the smoke sensor, and the second wedge-shaped block and the first wedge-shaped block are separated from each other through the attraction of the electromagnet to the iron block. At this time, due to the effect of the first coil spring, the movable plate moves down and resets. At this time, the first cooling hole and the second cooling hole no longer overlap, so that the outside air enters the cabinet, and at the same time the solenoid valve is opened, then The nitrogen in the nitrogen tank enters the cabinet, thereby reducing the oxygen in the cabinet rapidly, which has the effect of quickly extinguishing the fire. When the cabinet returns to normal, pull the movable plate upwards, and the first heat dissipation hole and the second heat dissipation hole overlap at this time , It is convenient for the usual ventilation inside the cabinet, and the operation is simple and fast.

Description

technical field [0001] The invention relates to the technical field of power cabinets, in particular to a power cabinet with a fire extinguishing function. Background technique [0002] Power cabinets are divided into power power cabinets, lighting power cabinets, and metering cabinets, and are the final equipment of the power distribution system. The power cabinet is a general term for the motor control center. The power 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 an environment with high temperature, excessive heat generation of electrical components may cause fire, and it is necessary t...
