Embodiment 1
As shown in Figs 1-4, the utility model provides a kind of low reactive power and low standby power loss charging pile, including charging pile
Ontology 1, charging pile body 1 are equipped with charging pile pedestal 2, and the front side upper surface of charging pile body 1 is equipped with charge state indicator
4, the top of charge state indicator 4 is equipped with sun-shading rain-proof plate 3, and charging 1 bottom right side of pile body is equipped with cable interface 9, cable
Charge cable 6 is connected on interface 9, the other side of charge cable 6 is connected with charging gun 5, is equipped with radiator-grid above cable interface 9
Plate 8 is equipped with charging gun fixing seat 7 above the web plate 8 that radiates, and charging pile body interior is equipped with circuit, and circuit includes three-phase input, the
Level-one switch, second level controlled switch, AC/DC power conversion module, lightning protection circuit, AC circuit breaker, monitoring unit, three-phase are defeated
The first order that enters to connect switch, first order switch includes but is not limited to AC circuit breaker, A.C. contactor, if first order switch in parallel
Dry second level controlled switch input terminal, each second level controlled switch input terminal series connection AC/DC power conversion module, AC/DC power
Input AC electricity is converted into direct current electricity output by conversion module.Lightning protection circuit is arranged between three-phase input and first order switch.
Second level controlled switch is connected in parallel with monitoring unit, and monitoring unit is used to control second level controlled switch according to human-computer exchange,
Control the switching of access or the isolation of AC/DC power conversion module.Any accessory power supply input that is in parallel in three-phase input, and
