Electrical equipment drainage system and electrical equipment using same

Abstract

The invention provides an electrical equipment drainage system and electrical equipment using the same. The electrical equipment drainage system comprises a shutter structure, ventilation cotton arranged on the rear side of the shutter structure, a pressing plate arranged on the rear side of the ventilation cotton, a water receiving tank arranged below the ventilation cotton, and a drainage pipe; the bottom of the water receiving tank is provided with a water outlet for discharging water in the water receiving tank to the outside of the electrical equipment; and the drainage pipe is provided with a first end communicating with the drainage port and a second end extending out of the electrical equipment, dustproof cotton is arranged in the second end, a bottom cover is further installed, the dustproof cotton is located on the inner side of the bottom cover, and screen holes allowing water to flow out are formed in the bottom cover. According to the invention, water in the water receiving tank is discharged to the outside of the electrical equipment through the drain pipe, so that the cabinet door is prevented from being dirty or rusted due to direct drainage from the cabinet door; the drainage pipe increases the water containing capacity, and the situation that suddenly increased water cannot be drained in time and flows into equipment is avoided; and the dustproof cotton can prevent external dust from entering the equipment, thereby ensuring that the electrical equipment meets the protection grade requirement.

Description

technical field [0001] The invention relates to the technical field of electrical equipment manufacturing, in particular to an electrical equipment drainage system and electrical equipment using the drainage system. Background technique [0002] The charging facility is a charging system that ensures the safe, reliable, and economical supply of electric energy for electric vehicles and the grid, and an outdoor electrical device that uses the charging device as a carrier to realize the interaction between electric vehicles and the grid. The protection level (IP54, IP55) of the shell in the charging equipment and the heat dissipation of the equipment form two contradictory and opposite technical difficulties. Under the premise that the equipment reaches the protection level, the internal heat dissipation of the equipment becomes a technology for the safe and stable operation of the charging equipment problem. [0003] The Chinese utility model patent with the authorized notif...
