Abstract
The present invention provides a kind of direct current rush-harvesting and rush-planting charging pile rush-harvesting and rush-planting charging output self-locking protective circuit, including two two hilted broadsword double-gate relays, a hilted broadsword list lock relay, bus high voltage connector two, A rifle high voltage connector two and B rifle high voltage connector five parts.The on-off of control bus, A rifle, B rifle contactor is distinguished by the relay of two hilted broadsword double-gates and a hilted broadsword list lock.When A, B rifle contactor simultaneously close off connection, the self-locking of bus contactor is realized, to completely cut off the voltage circuit of A, B rifle.
Description
Technical field
It charges the present invention relates to direct current rush-harvesting and rush-planting charging pile rush-harvesting and rush-planting and exports self-locking protective circuit.
Background technique
Increasingly depleted with world petroleum resource, the power source of automobile will have to the constraint for gradually getting rid of petroleum resources
And some new energy are used, this pushes directly on an important technical revolution of automobile industry, Future New Energy Source automobile substitution
Orthodox car trend will become inevitable.
Charging core of the automobile charging pile as New-energy electric vehicle, will also grow rapidly, and will expedite the emergence of out Pang therewith
Big industrial economy effect, the huge market space are generally had an optimistic view of in the industry.
Direct-current charging post, since power is big, will can cause many safety issues to automobile charging process.How to subtract
The security risk of small charging is the thing that producer pays high attention to.The end of the year in 2015 has issued new national standard, and new standard is to charging interface
The specification of comprehensive system has been carried out with communication protocol, it is ensured that electric car and charging equipment interconnect.This is conducive to
The general generality of entire electric car charging network.
When rush-harvesting and rush-planting charging pile simultaneously charges to two electric cars, it is possible that one the voltage of rifle, electric current string to separately
On one rifle.
Summary of the invention
The present invention is directed to current electric car rush-harvesting and rush-planting DC charging, and rush-harvesting and rush-planting charging pile simultaneously charges to two electric cars
When, it is possible that voltage, the electric current string to another deficiency on rifle rifle, provides a kind of direct current rush-harvesting and rush-planting charging pile rush-harvesting and rush-planting
Charging output self-locking protective circuit, when rush-harvesting and rush-planting charging pile simultaneously charges to two electric cars, due to the self-locking reason of hardware
The voltage that Bus cutting is prevented a rifle, electric current string are understood to another on rifle.So that equipment has high security, and
It is adapted to new national standard.
The present invention realizes that its technical purpose technical solution is: a kind of direct current rush-harvesting and rush-planting charging pile rush-harvesting and rush-planting charging output self-lock protection
Circuit, including bus contactor KM1 and bus contactor KM2;A rifle contactor KM3 and A rifle contactor KM4;B rifle contactor KM5
With B rifle contactor KM6;It is characterized by also including A rifle control relay S1, B rifle control relay S3 and bus contactor controls
Relay S2 processed;
The bus contactor control relay S2 is hilted broadsword list lock relay;A rifle controls relay S1 and B rifle and controls relay
Device S3 is hilted broadsword double-gate relay;
The common end of the A rifle control relay S1 and B rifle control relay S3 links together, while connecting work electricity
The opened point of pressure, normally closed point and bus contactor control relay S2 that A rifle controls relay S1 and B rifle control relay S3 connects
It is connected together;
The opened point that A rifle controls relay S1 is grounded by the coil of A rifle contactor KM3 or A rifle contactor KM4;B rifle control after
The opened point of electric appliance S3 is grounded by the coil of B rifle contactor KM5 and B rifle contactor KM6;
The normally closed point that bus contactor controls relay S2 is grounded by the coil of bus contactor KM1 or bus contactor KM2.
The present invention is when rush-harvesting and rush-planting charging pile simultaneously charges to two electric cars, since the self-locking reason of hardware can be bus
Cutting prevents the voltage of a rifle, electric current string to another on rifle.So that equipment has high security, and it is adapted to new
National standard.
Below with reference to drawings and examples, the present invention is described in detail.
Detailed description of the invention
Fig. 1 direct current rush-harvesting and rush-planting charging pile rush-harvesting and rush-planting charging output self-locking protective circuit schematic diagram of the present invention.
Specific embodiment
Embodiment 1, the present embodiment circuit diagram as shown in Figure 1, in circuit structure include two hilted broadsword double-gate relays,
It is that A rifle control relay S1 and B rifle control relay S3 respectively, both is hilted broadsword list lock relay, additionally includes mother
Line contactor controls relay S2, it is a hilted broadsword list lock relay, to two bus high voltage connectors: bus contactor
What KM1 and bus contactor KM2 was controlled, there are two A rifle high voltage connectors, is the contact of A rifle contactor KM3 and A rifle respectively
The opened point that device KM4, A rifle controls relay S1 is grounded by the coil of A rifle contactor KM3 or A rifle contactor KM4;The control of A rifle
When relay S1 is directed toward opened point, there is electric current to tide in the coil of A rifle contactor KM3 or A rifle contactor KM4, A rifle contactor
The relay of KM4 or B rifle contactor KM4 is attracted.There are two same B rifle high voltage connectors, is B rifle contactor KM5 and B respectively
The opened point that rifle contactor KM6, B rifle controls relay S3 is grounded by the coil of B rifle contactor KM3 or B rifle contactor KM4;B
When rifle controls relay S1 direction opened point, there is electric current to tide in the coil of A rifle contactor KM3 or A rifle contactor KM4, A rifle connects
The relay of tentaculum KM3 or A rifle contactor KM4 is attracted.
It is direct current rush-harvesting and rush-planting charging pile rush-harvesting and rush-planting charging output protection circuit as shown in Figure 1, A rifle controls relay S1 and B in figure
Rifle control relay S3 is hilted broadsword double-gate relay, and S2 is hilted broadsword list lock relay, and KM1, KM2 are bus contactor, KM3,
KM4 is A rifle contactor, and KM5, KM6 are B rifle contactor.The common end of S1 and S3 links together, while connecting+12V voltage,
The normally closed point of S1 and S3 and the opened point of S2 link together, and thereby realize the circuit of control+12V voltage.When A rifle controls
When relay S1 and B rifle control relay S3 are simultaneously closed off, the opened point connection of relay S1, S3 shut off control at this time
+ 12V the voltage circuit of bus relay, to realize the hardware self-locking function and A rifle and B rifle output loop of bus contactor
Isolation.It greatly ensure that the safety of rush-harvesting and rush-planting charging.
Distinguish by the relay of two hilted broadsword double-gates and a hilted broadsword list lock control bus, A rifle, B rifle contactor
On-off.When A, B rifle contactor simultaneously close off connection, the self-locking of bus contactor is realized, so that the voltage for having completely cut off A, B rifle returns
Road.
