A distribution cabinet for power system

Abstract

The invention relates to a heat dissipation-efficient intelligent power distribution cabinet for a power system. The cabinet comprises a base, a cabinet, a cabinet door and two heat dissipation mechanisms; each heat dissipation mechanism comprises a ventilation assembly and a cleaning assembly; the ventilation assembly comprises a ventilation pipe, a first filter screen, a lifting unit and a limiting unit; and the cleaning assembly comprises a water supply assembly, a cleaning box, a water draining pipe, a return pipe and a filtering assembly, wherein the filtering assembly comprises a secondfilter screen, a connecting rod, a first motor, a dust-removing assembly and a moving assembly. According to the heat dissipation-efficient intelligent power distribution cabinet for the power systemof the invention, the ventilation pipe in the heat dissipation mechanism can realize air circulation; the first filter screen is adopted to filter out dust in the air; after the first filter screen operates a period of time, the first filter screen is cleaned through the cleaning assembly, and the ventilation and heat dissipation capacity of the ventilation pipe can be recovered; an aqueous solution which has been used for cleaning is filtered and then is returned to a storage tank, and therefore, the consumption of water resource can be decreased, and the practicability of the power distribution cabinet can be improved.

Description

technical field [0001] The invention relates to the field of intelligent power equipment, in particular to a power distribution cabinet for a power system. Background technique [0002] Power distribution cabinet is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch, and the circuit can be cut off or alarmed by means of a protective device in case of failure or abnormal operation. The power distribution cabinet can also display various parameters in operation with the help of measuring instruments, and can also adjust some electrical parameters, and prompt or send out signals for deviations from normal working conditions through indicator lights and speakers. [0003] In order to make the circuit components inside the ...

Problems solved by technology

[0003] In order to make the circuit components inside the power distribution cabinet work in a suitable temperature environment, there are usually several cooling vents on the side panels of the power distribution cabinet for ventilation and heat dissipation. At the same time, it is easy to inhale the dust in the external air into the cabinet, resulting in poor air circulation and reducing the heat dissipation performance. Even if a fan or filter is added to the opening of the ventilation pipe, after long-term operation, the dust is easily adsorbed on the ventilation pipe. Openings, leading to a decrease in ventilation performance, reducing the heat dissipation capacity and practicality of the power distribution cabinet
