Abstract

The invention relates to the technical field of machinery. An electrical cabinet with a built-in inert gas protection mechanism comprises an electrical cabinet body, wherein the electrical cabinet body is a sealed electrical cabinet body, an air inlet is formed in the electrical cabinet body and is connected with a gas storage cavity, an inert gas is stored in the gas storage cavity, a first solenoid valve is arranged between the air inlet and the gas storage cavity and is used for controlling an air path to be connected and disconnected, an air discharging hole is formed in the electrical cabinet body and is used for discharging gas, the air discharging hole is connected with an air suction pump, a second solenoid valve is arranged at an air outlet of the air suction pump, the electricalcabinet body is provided with a temperature sensor, the temperature sensor is connected with a miniature processor system, and the miniature processor system is connected with and controls the air suction pump, the first solenoid valve and the second solenoid valve. By monitoring a temperature condition of the electrical cabinet body, the working safety of a component in the electrical cabinet isconveniently ensured, and the corrosion of an external fire is prevented.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an electrical cabinet. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of components. When the converter in the cabinet fails, or the converter is short-circuited due to improper operation, the discharge arc generated in the cabinet is likely to cause an open flame, and in severe cases, an explosion will occur. [0003] The existing electrical cabinets are not strong in flame retardancy, and are still in the weak link of design in terms of reducing the impact of explosions or open flames. Contents of the invention [0004] The object of the present invention is to provide an electrical cabinet with a built-in inert gas protection mechanism to solve at least one of the above technical problems. [0005] The technical problem solved by the present invention can adopt following technical scheme to realize: [0...
