Description
Technical field
The present invention relates to the leakage protection structure of a kind of charging pile, for the safeguard protection of charging pile.
Background technology
Electric automobile is little to surrounding air and noise pollution, is rapidly developed, and becomes city, rural preferred traffic work
Tool.In order to adapt to the fast development of electric automobile, needing to build substantial amounts of charging pile, the safety problem of charging pile mentions discussion day
Journey.In order to prevent charging pile from leaking electricity, general employing installs earth leakage protective device, by detecting the small electric leakage of charging pile body, logical
Cross controller and cut off charging pile power supply, prevent the generation of security incident.This protection device has the drawback that: to charge cable
Electric leakage not there is defencive function, safety coefficient is the highest.
Summary of the invention
The present invention proposes the leakage protection structure of a kind of charging pile, with solve that prior art exists to charge cable
Electric leakage does not have defencive function, the problem that safety coefficient is the highest.
The technical solution adopted in the present invention: the leakage protection structure of a kind of charging pile, including charging pile body and charging
Cable, the outfan of charging pile intrinsic charging pile power supply is connected with charge cable, it is characterised in that at described charging wire
The outside of cable is provided with flexible cable shielding layer, is provided with insulating barrier in the outside of this cable shielding layer, this cable shielding layer with
One detection of electrical leakage module connects, and the outfan of this detection of electrical leakage module and the input of a microprocessor connect, this microprocessor
Outfan be connected with the control end of the chopper being connected between charging pile power supply and charge cable.

One input connects.
The invention has the beneficial effects as follows: by increasing screen layer in charge cable, and this screen layer is carried out detection of electrical leakage,
Cut off the electricity supply in time when charge cable exists small electric leakage, effectively prevent from preventing the generation of security incident；It addition, in charging
The housing bilayer earth leakage protective measure of stake, further increases reliability and safety.Simple in construction, low cost, easily realize,
Using effect is good, its popularization and application.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic block diagram of one embodiment of the invention；
Fig. 2 is the overall structure schematic block diagram of another embodiment of the present invention.
Detailed description of the invention
Seeing Fig. 1, the first embodiment of the leakage protection structure of a kind of charging pile of the present invention, including charging pile body and filling
Electric wire cable 3, the outfan of charging pile intrinsic charging pile power supply 1 is connected with charge cable 3 by chopper 2.Described
The outside of charge cable 3 is provided with the cable shielding layer 6 of metal gauze composition, is provided with insulating barrier 7 in the outside of this cable shielding layer 6
(rubber layer), this cable shielding layer 6 is connected with a detection of electrical leakage module 4, the outfan of this detection of electrical leakage module 4 and microprocessor
The input of 5 connects, and the outfan of this microprocessor 5 is connected with the control end of chopper 2.
Seeing Fig. 2, the second embodiment of the present invention is on the basis of a upper embodiment, at the machine of described charging pile body
Shell is externally provided with insulating barrier, sets casing screen layer 8 in the outside of this insulating barrier, this casing screen layer 8 and another detection of electrical leakage module 9
Connecting, the outfan of this detection of electrical leakage module 9 is connected with another input of described microprocessor 5.
The detection of electrical leakage module 4 of the present invention and detection of electrical leakage module 9 can use the leakage current of conventional earth leakage protector to examine
Survey part.
The operation principle of the present invention is, have between charge cable 3 and cable shielding layer 6 small electric leakage (such as several microamperes, can
To set) time, the leakage current signal of detection is sent to microprocessor 5 by detection of electrical leakage module 4, and the output of microprocessor 5 controls
Chopper 2 cuts off charging pile power supply 1.Due to the fully wrapped around charge cable of cable shielding layer 63, as long as therefore charge cable 3 is any
There is electric leakage in position, all can control chopper 2 by microprocessor 5 and cut off charging pile power supply 1, and safety is greatly improved.For
Second embodiment, casing screen layer 8 too increases detection of electrical leakage, controls process identical with first embodiment, adds one peace
Full guard measure, further increases safety.
