Abstract

The invention discloses an intelligent electric charging pile transformer, and relates to the technical field of charging piles. The intelligent electric charging pile transformer comprises a transformer body, a gland, an oil injection cavity, an oil injection hole, an oil injection plug, a sleeve, a pin, a high-voltage bushing, a copper cap, a lead connector and a wiring board; the gland is arranged at the periphery of the high-voltage bushing at the upper end of the transformer body, the oil injection cavity is formed between the gland and the transformer body, the oil injection hole communicated with the oil injection cavity is formed in the gland, and the oil injection plug is arranged at the upper end of the oil injection hole; the sleeve is inserted into the center of the gland, thehigh-voltage bushing is inserted into the sleeve, and the high-voltage bushing is connected with the sleeve through the pin; the copper cap is arranged on the high-voltage bushing, and the lead connector inside the high-voltage bushing is in circuit connection with a terminal board. The intelligent electric charging pile transformer is good in sealing performance, no water enters the high-voltagebushing, the fault rate is lowered, use is safer, wiring is convenient, and the transformer has the advantages of being simple in structure, reasonable in setting, low in manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to an intelligent electric charging pile transformer. Background technique [0002] Charging piles can be fixed on the ground or walls, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. [0003] The transformer is used in the open air for a long time, and the high-voltage bushing in the transformer will cause the main insulation to age and the insulation level will decrease after the water enters it; the breakdown voltage of the transformer oil is low; or it is caused by the expansion of other faults, such as inter-turn short circuit or gro...
