Electrical cabinet with high temperature early warning system

Abstract

An electrical cabinet with a high temperature early warning system disclosed by the present invention comprises a cabinet body, a side plate is fixedly connected to the side surface wall in the cabinet body, a top plate is fixedly connected to the upper end surface of the side plate, a shell is fixedly connected to the upper end surface of the top plate, a cavity is formed in the shell, and metal mercury is arranged in the cavity. The inner wall of the cavity is slidably connected with a piston rod, and the lower end of the piston rod is fixedly connected with a rack. According to the invention, when the temperature rises, the pressure in the cavity is increased by utilizing thermal expansion and cold contraction of liquid metal mercury, the piston rod is driven to move downwards, and two control valves are opened through rack transmission, so that a sodium bicarbonate solution and an aluminum sulfate solution enter the reaction kettle to react, a large amount of gas is generated, and a rotating block is pushed to rotate; and a pendulum bob is driven to knock the bells through transmission of the rotating shaft, a reset mechanism is arranged, the pendulum bob swings back and forth to knock the bells at the two sides, and a better warning effect is achieved.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to an electrical cabinet with a high temperature early warning system. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of components. The electrical cabinet is widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. Wait. [0003] Most of the existing electrical cabinets used indoors lack the corresponding high temperature early warning mechanism, and there are many kinds of electrical components inside the indoor electrical cabinet, which will generate a lot of heat during operation. If you are reminded, the electrical components will be in a high temperature environment for a long time, which will easily cause damage to the electrical components and cause unnecessary...
