Lightening proof system for alternating current charging pile

Abstract

The invention discloses a lightening proof system for an alternating current charging pile and belongs to the field of alternating current charging piles. According to a technical solution of the lightening proof system, the lightening proof system comprises a lightning protection system, a high voltage inlet wire and a voltage transformer, wherein the lightning protection system is electrically connected with the voltage transformer via the high voltage inlet wire, one end of the voltage transformer is electrically connected with a low voltage outlet wire, and an electric surge protection device is fixedly mounted on a middle part of the high voltage inlet wire; an ammeter is fixedly mounted on one end, positioned far away from the voltage transformer, of the low voltage outlet wire; oneend, positioned far away from the low voltage outlet wire, of the ammeter is electrically connected with a non-vehicle-mounted charging device; one side, positioned away from the ammeter, of the non-vehicle-mounted charging device is electrically connected with an alternating current circuit; a lower end of the alternating current circuit is electrically connected with an electric automobile, anda vehicle-mounted charger is fixedly mounted on a front end of the electric automobile. Lightening proof effects can be effectively reached via the lightening proof system for the charging pile, current protection effects can be exerted, and current stability can be increased.

Description

technical field [0001] The invention relates to the field of AC charging piles, in particular to a lightning protection system for AC charging piles. Background technique [0002] The device used to charge power-consuming electrical appliances installed in public buildings is a charging pile, including a cabinet body, a cabinet door, and a charging system, which can effectively charge electrical appliances to achieve convenience. In this case, it is easy to cause the charging pile to be struck by lightning, resulting in serious accidents. [0003] The Chinese patent with the authorized notification number CN207082758U discloses a charging pile. The structure of the invention is reasonable. The cold air outside the cabinet is drawn into the cabinet through the vent through the exhaust fan, and the cold air drawn into the cabinet is then combined with the inside of the cabinet. The electronic devices are used for heat exchange, and the air after heat exchange is discharged fr...

[0003] The Chinese patent with the authorized notification number CN207082758U discloses a charging pile. The structure of the invention is reasonable. The cold air outside the cabinet is drawn into the cabinet through the vent through the exhaust fan, and the cold air drawn into the cabinet is then combined with the inside of the cabinet. The electronic devices are used for heat exchange, and the air after heat exchange is discharged from the cabinet through the air outlet to cool down the inside of the cabinet. However, in thundercloud weather, it is easy to cause the charging pile to be struck by lightning. The high-voltage current causes the charging pile to be destroyed, and the protection effect on the current is poor
