The invention discloses an air isolation switch for a charging pile. The air isolation switch comprises an isolation switch which is fixed on the charging pile, a controller and a water level sensor which is fixed on the bottom of the charging pile. The controller is electrically connected with the water level sensor. The isolation switch is internally provided with an overcurrent circuit breakingassembly, an anti-flooding circuit breaking assembly corresponding to the overcurrent circuit breaking assembly and an isolation assembly. The isolation assembly is arranged at the connection of theisolation overcurrent circuit breaking assembly and the anti-flooding circuit breaking assembly. The isolation switch is also internally provided with two electromagnetic tripping assemblies which areused for controlling the movement of the overcurrent circuit breaking assembly and the anti-flooding circuit breaking assembly. The controller is arranged, and when the water level spreads to a dangerous position, the movement of the electromagnetic tripping assemblies can be controlled so that the anti-flooding circuit breaking assembly can be disconnected from the over-current circuit breakingassembly in use, and the problem that the charging pile leaks electricity and hurts people due to the fact that the worker does not cut off the power supply in time can be effectively avoided.
Description
technical field [0001] The invention relates to the technical field of charging piles, in particular to an air isolating switch for charging piles. Background technique [0002] In recent years, my country has vigorously supported the development of the electric vehicle industry and the construction of charging infrastructure. The number of electric vehicles and charging infrastructure has grown rapidly. According to the "Guidelines for the Development of Electric Vehicle Infrastructure (2015-2020)" issued by the National Development and Reform Commission, by 2020, my country will add more than 4.8 million decentralized charging piles to meet the charging needs of 5 million electric vehicles nationwide. [0003] With the continuous popularization and development of electric vehicles, the construction of charging infrastructure is imminent. The establishment of charging piles has the characteristics of many distribution points and wide dispersion. However, various safety issue...
