Technical field
This utility model relates to car electrics, is specifically related to a kind of heavy-duty car accumulator protection circuit.
Background technology
The power supply of heavy-duty car is composed in parallel by electromotor and accumulator, the integrated rectifier bridge of generator.Generally rectification
Bridge negative pole connects battery positive voltage, and cathode rectifier connects battery terminal negative pole, if wrong can cause accumulator and electromotor
Internal short-circuit thus burn electromotor.The positive terminal of the accumulator of automobile application is relatively thick, and negative terminal is relatively thin, accumulator
Come anti-reverse in this way.But this mode is not bery reliable, and once electromotor will be caused serious consequence by both positive and negative polarity wrong.
Utility model content
The purpose of this utility model is to provide a kind of heavy-duty car accumulator anode and cathode reverse connection prevention protection circuit and heavy vapour
Car.
This system comprises accumulator, electromotor, battery main switch, protection diode, buzzer diode, anti-reverse relay
Device, buzzer form.When accumulator anode and cathode correctly connects, accumulator is powered to car load with parallel operation of generator, works as accumulator positive
Negative pole connects inverse time anti-reverse relay and stops accumulator to be connected with electromotor, and has buzzer call to point out, thus protects generating
Machine.This utility model is with a wide range of applications on heavy vehicles.
Accumulator is attached with electromotor by the main power source end of battery main switch and anti-reverse relay.
Battery main switch controls anti-reverse relay, only battery main switch Guan Bi, the control end of anti-reverse relay
Just can be energized, accumulator is just had ready conditions and electromotor is attached.
The control end negative pole of anti-reverse relay connects protection diode, protects diode cathode ground connection.The most correctly connect
When connecing both positive and negative polarity and the battery main switch Guan Bi of accumulator, protection diode just can turn on, the main power source end of anti-reverse relay
Just can be in conjunction with, accumulator just can be connected with electromotor.If the both positive and negative polarity reversal connection of accumulator, protection diode does not turns on, and stores
Battery also will not be connected with electromotor.
Battery main switch controls the connection of accumulator and buzzer, buzzer Diode series buzzer and ground wire it
Between, buzzer diode cathode is connected with ground wire.If the both positive and negative polarity of accumulator correctly connects, buzzer will not pipe prompting,
If the both positive and negative polarity reversal connection of accumulator, buzzer carries out the prompting that pipes.
The technical solution of the utility model is:
A kind of heavy-duty car accumulator anode and cathode reverse connection prevention protection circuit, it is characterised in that
Including accumulator 1, electromotor 7, battery main switch 2, protection diode 6, anti-reverse relay 5；
Accumulator is attached with electromotor by the main power source end of battery main switch and anti-reverse relay；
Accumulator 1 minus earth, accumulator 1 positive pole connects battery main switch 2, and battery main switch 2 connects anti-reverse relay
The main power source of device 5 is rectified pole and controls to rectify pole, and the main power source end negative pole of anti-reverse relay 5 connects electromotor positive pole, counnter attack
The end negative pole that controls of contact relay 5 connects the positive pole of protection diode 6, the minus earth of protection diode 6.
Further, also including buzzer 3, buzzer diode 4, battery main switch controls accumulator and buzzer
Connecting, buzzer Diode series is between buzzer and ground wire, and buzzer diode cathode is connected with ground wire.
Further, buzzer is configured that when accumulator 1 both positive and negative polarity correctly connects, buzzing after battery main switch 2 Guan Bi
Device diode 4 reverse bias does not turns on, and buzzer does not works；When accumulator 1 both positive and negative polarity connects inverse time, and buzzer diode 4 is led
Logical, buzzer 3 pipes and points out accumulator 1 both positive and negative polarity to connect instead.
A kind of heavy-duty car, it uses above-mentioned a kind of heavy-duty car accumulator anode and cathode reverse connection prevention protection circuit.
Accompanying drawing explanation
Fig. 1 is that the electricity of an embodiment of heavy-duty car accumulator anode and cathode reverse connection prevention protection circuit of the present utility model returns
Lu Tu.
Detailed description of the invention
In conjunction with drawings and the specific embodiments, this utility model is described in further detail.
Accumulator 1 minus earth, accumulator 1 positive pole connects battery main switch 2, and battery main switch 2 connects anti-reverse relay
The main power source of device 5 is rectified pole and controls to rectify pole, and the main power source end negative pole of anti-reverse relay 5 connects electromotor positive pole, counnter attack
The end negative pole that controls of contact relay 5 connects the positive pole of protection diode 6, the minus earth of protection diode 6.
When accumulator 1 both positive and negative polarity correctly connects, battery main switch 2 closes after current and flows through anti-reverse relay 5 and control
End and protection diode 6, anti-reverse relay 5 closes, and accumulator 1 is connected with electromotor 7, and the two parallel connection is powered to car load, this
Time electromotor 7 will not internal short-circuit and burn.
If when accumulator 1 both positive and negative polarity connects inverse time, and the ground wire in Fig. 1 all becomes positive pole, if anti-reverse relay 5 is main
Power end engages battery main switch 2 simultaneously and closes, and the internal rectifier bridge diode of electromotor 7 will turn on, and electromotor will burn.
And real-time condition to be accumulator 1 both positive and negative polarity connect inverse time, after battery main switch 2 Guan Bi, owing to the ground wire in Fig. 1 becomes positive pole, protect
Protecting diode 6 reverse bias can't turn on, so anti-reverse relay 5 main power source end will not be in conjunction with, electromotor also will not burn
Ruin.
Accumulator 1 minus earth, accumulator 1 positive pole connects battery main switch 2, and battery main switch 2 is just connecting buzzer 3
Pole, buzzer 3 negative pole connects buzzer diode 4 negative pole, buzzer diode 4 plus earth.
When accumulator 1 both positive and negative polarity correctly connects, after battery main switch 2 Guan Bi, buzzer diode 4 reverse bias will not
Conducting, so buzzer does not works.If when accumulator 1 both positive and negative polarity connects inverse time, and the ground wire in Fig. 1 all becomes positive pole, buzzing
Device diode 4 turns on, and buzzer 3 pipes and points out accumulator 1 both positive and negative polarity to connect instead.
Finally should be noted that: above example is only in order to illustrate that the technical scheme of this case is not intended to limit；Although
Being described in detail this case with reference to preferred embodiment, those of ordinary skill in the field are it is understood that the most permissible
The detailed description of the invention of this case is modified or portion of techniques feature is carried out equivalent；Without deviating from the technical program
Spirit, it all should be contained in the middle of the technical scheme scope that this case is claimed.
