Electronic control power distribution cabinet with heat dissipation function

Abstract

The invention relates to an electronic control power distribution cabinet, which comprises a cabinet body and an impact assembly, a mounting groove is formed in the rear end face, close to the bottom, of the cabinet body, a mounting shell is fixedly mounted on the mounting groove, sealing is formed between the mounting shell and the cabinet body, a torsion feeding assembly is mounted on the mounting shell, and a gas production part is mounted on the torsion feeding assembly; the impact assembly is installed in the mounting shell and used for impacting the gas production part so as to generate gas used for blowing the interior of the cabinet body. When a temperature sensor detects that the temperature in the electronic control cabinet is higher than the temperature in the temperature sensor, a controller drives a hydraulic cylinder to push a fan-shaped impact head to impact a sodium azide disc, the fan-shaped sodium azide subjected to violent impact is rapidly decomposed to generate a large amount of nitrogen, the generated nitrogen enters a heat dissipation pipe fitting through an exhaust pipe, and the heat dissipation pipe fitting is used for blowing air to elements and instruments on an assembly frame, so that internal airflow flows more intensively, and internal hot air can be exhausted quickly, thereby accelerating the radiating rate.

Description

technical field [0001] The invention relates to the technical field of electric control power distribution, in particular to an electric control power distribution cabinet for low-voltage electrics. Background technique [0002] Electric control distribution cabinet is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, its arrangement should meet the requirement of normal operation of power system, is convenient for maintenance, A control cabinet (box) that does not endanger the safety of people and surrounding equipment. Including (distribution cabinet) (distribution box) (electrical control cabinet), etc., the circuit can be connected or disconnected by manual or automatic switch during normal operation. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in op...

AI Technical Summary

Problems solved by technology

[0003] At present, the electric control cabinets on the market will have heat dissipation windows on both sides for the cooling and dust-proof functions. Although it has the function of cooling and cooling, it will also bring new problems, such as dust easily entering the electric control cabinet. It is impossible to perform dust-proof treatment while achieving the heat dissipation function, which greatly affects the practicability of the electric control cabinet, and because the installation frame of the existing electric control cabinet is set inside the switch cabinet, the field of view of the entire installation frame is limited. The openness is poor, and the operating range of the staff is narrow, making it uncomfortable for the staff to operate when installing or maintaining instruments and components on the mounting frame
