Description
Technical field
This utility model relates to a kind of charging pile safety guard class technical field, especially charging pile grounding device.
Background technology
Along with electric automobile charging station and a large amount of of charging pile build and application, its safety increasingly comes into one's own, especially
It is that direct-current charging post power is big, volume is big, voltage is high, and is often furnished with accumulator and carries out energy storage, and structure is complicated, works as direct current
The when that side insulation being the best, device damage, fire, and the person can be caused to get an electric shock, owing to DC side leak current fault cannot make friendship
The earth leakage protective device action of stream side, so, increase DC side Insulation monitoring and earth-fault protection be particularly important,
Getting an electric shock for the person, the general the most only shell at charging pile body of current charging pile sets grounding device, at direct current negative pole, direct current
Positive pole and charging gun and automobile junction the most do not set grounding device, and in charging process, people touches the direct current negative pole of electric leakage, straight
Stream positive pole, automobile case all can cause person electric shock, owing to charging pile is installed on outdoor, caused equipment to enter by clashing into, raining
Water or humidity, cable failure equally likely possibility are varied, being all easily caused insulation and declining, and power station internal may install a large amount of
Accumulator carries out energy storage, and the insulation decline of accumulator anode and cathode also can constitute loop and threaten personal safety.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide charging pile grounding device, including charging pile
Body, grounding device one, insulation against ground detection device, charging gun, crown cap, spring, charging wire one, grounding device two, charging
Line two, grounding device three, charging pile this most internal sets insulation against ground detection device, shell connects grounding device one, divide into charging wire one,
Charging wire two, charging wire one shell sets grounding device two, and charging wire two shell sets grounding device three, charging wire one, charging wire two
Another terminates charging gun, and charging gun head sets crown cap, and described crown cap sets spring with charging gun and is connected, and this utility model fills
Electricity stake body housing, positive and negative charging wire shell an ancient unit of weight set grounding device, and charging gun head sets flip-shell crown cap, rechargeable metal
Lid is connected with automobile metal shell, and connects with grounding device, carries out comprehensive ground connection, when insulation against ground detection device detection electricity
When flowing dew more than setting value, automatically cutting off power supply, eliminate danger hidden danger.
For reaching above-mentioned purpose, the technical solution of the utility model is: charging pile grounding device, including charging pile body,
Grounding device one, insulation against ground detection device, charging gun, crown cap, spring, charging wire one, grounding device two, charging wire two,
Grounding device three, described charging pile this most internal sets insulation against ground detection device 2, shell connects grounding device one, divide into charging wire one,
Charging wire two, described charging wire one shell sets grounding device two, and described charging wire two shell sets grounding device three, charging wire one,
Another termination charging gun of charging wire two, described charging gun head sets crown cap, and described crown cap sets spring with charging gun and is connected.
The beneficial effects of the utility model are: this utility model charging pile body housing, positive and negative charging wire shell an ancient unit of weight set and connects
Ground device, charging gun head sets flip-shell crown cap, and rechargeable crown cap is connected with automobile metal shell, and with grounding device even
Logical, carry out comprehensive ground connection, when insulation against ground detection device detection leakage of current is more than setting value, automatically cuts off power supply, disappear
Except dangerous hidden danger.
