Problems solved by technology

[0004] The purpose of the present invention is to provide a high-current fast charger applied to electric buses, which prevents rainwater from dripping along the outside of the tower insulators in rainy days to form a continuous water film , resulting in electrical conduction between the horizontal bar and the busbar, achieving all-weather strong insulation, effectively solving the problem that the existing DC charging rack cannot be used due to poor insulation in rainy days

Abstract

The invention relates to a large-current quick charger applied to electric buses. The quick charger comprises a charging power cabinet, a foundation, two positive electrode fixing pipes, two negative electrode fixing pipes, a positive electrode busbar and a negative electrode busbar, wherein one end of a positive electrode horizontal rod is fixed on a positive electrode vertical rod and is perpendicular to the positive electrode vertical rod; positive electrode cables are mounted on the positive electrode fixing pipes respectively; negative electrode cables are mounted on the negative electrode fixing pipes respectively; each high-voltage insulator comprises a cylindrical main body, two top umbrella-shaped insulation sheets, two sub-top umbrella-shaped insulation sheets and a middle umbrella-shaped insulation sheet; the corresponding top umbrella-shaped insulation sheets are positioned at the two ends of each cylindrical main body respectively; each middle umbrella-shaped insulation sheet is positioned in the middle of the corresponding cylindrical main body; each sub-top umbrella-shaped insulation sheet is positioned between the corresponding top umbrella-shaped insulation sheet and the corresponding middle umbrella-shaped insulation sheet. Through the adoption of the large-current quick charger disclosed by the invention, the phenomena that on rainy days, rain water drips along outer sides of the tower-type insulators, and continuous water films are formed are avoided, so that all-weather high insulation is realized, and the problem that on rainy days, a conventional direct-current charging rack cannot be used because the conventional direct-current charging rack is poor in insulation is solved.

Description

technical field [0001] The invention relates to a high-current fast charger applied to electric buses, and belongs to the technical field of automatic charging of electric vehicles. Background technique [0002] With the increasing demand for diversified energy sources for vehicles, electric vehicles are increasingly appearing in the automotive market. Different from traditional fuel vehicles, the power system of electric vehicles does not have a fuel engine, but consists of charging modules, batteries and motors, etc. Composition, the battery is connected to the mains through the charging port of the charging module for charging, the battery is the power source of the motor, and the motor rotates to drive the wheels. [0003] The existing problems of electric vehicles are that it is difficult to charge, takes a long time, and the driving distance is short. Generally, it takes 2 to 3 hours to charge once and can travel about 150 kilometers. It cannot be compared with fuel ve...
