Technical field
This utility model relates to a kind of passenger vehicle electric heating wind electric system, particularly relates to a kind of novel high-pressure electric heating wind Electrical System
System.
Background technology
At present, country greatly develops new-energy automobile, and city bus field integral new-energy passenger the most gradually substitutes tradition
Passenger vehicle enters the arena of history.
The water-heating system that tradition passenger vehicle uses is inapplicable on integral new-energy passenger, the product needed of high pressure PTC electric heating sheets
Replace traditional hot-water heating fin for integral new-energy passenger.Unlike traditional hot-water heating fin, PTC electrothermal radiating fin
Temperature is higher, and warning time control electrically heated for high pressure and temperature are higher is required for electric system and is analyzed opinion
Card.Warning message etc. when control that PTC electric heating sheets high pressure powers on, the control of cooling fan, temperature are too high is required for carrying out
Reasonably control, the reliability application of integral high pressure electric heating wind can be realized.
Utility model content
This utility model is for the shortcoming solving above-mentioned prior art, it is provided that a kind of novel high-pressure electric heating wind Electrical System
System, this system can accurately control the electrically heated power on/off of high-tension electricity warm braw electrical equipment, working time of cooling fan and different
Overtemperature alarm information in the case of Chang.
This utility model is achieved in that a kind of novel high-pressure electric heating wind electric system, and this system includes low-voltage direct
Loop, HVDC loop, control loop and high temperature alarm circuit, wherein, low-voltage dc power supply and cooling fan series connection are formed
Low-voltage direct loop, high-voltage DC power supply, the normally opened contact of high voltage connector and the series connection of PTC fin form HVDC and return
After road, the coil of high voltage connector and the coils from parallel connection of coils of relay, formed source-series with temperature switch and low-voltage DC is controlled again
Loop processed, high temperature alarm circuit is provided with the switch of relay.
Described low-voltage dc power supply is 24V DC source.
Described high-voltage DC power supply is 600V DC source.

Relative to prior art, the beneficial effects of the utility model are:
This utility model provides a kind of novel high-pressure electric heating wind electric system, by low-voltage direct circuit controls radiation air
The operation of machine, this low-voltage direct loop also controls to control work and the stopping of PTC fin by controlling high voltage connector, should
With temperature switch, the alarm signal of abnormal work situation is exported for client.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of novel high-pressure electric heating wind electric system, this system includes low-voltage direct loop, HVDC
Loop, control loop and high temperature alarm circuit, wherein, low-voltage dc power supply 1 and cooling fan 2 series connection form low-pressure direct and flow back to
Road, high-voltage DC power supply 3, the normally opened contact of high voltage connector 4 and PTC fin 5 series connection form HVDC loop, high-voltage connecting
Formation of connecting with temperature switch 7 and low-voltage dc power supply 1 again after the coil of tentaculum 4 and the coils from parallel connection of coils of relay 6 controls back
Road, high temperature alarm circuit is provided with the switch of relay 6.
Described low-voltage dc power supply 1 is 24V DC source.
Described high-voltage DC power supply 3 is 600V DC source.
Described cooling fan 2 is by two cooling fan parallel connections.
In use, electric heating wind is opened, by low-voltage direct circuit controls electric heating wind-powered electricity generation device internal heat dissipating blower fan 2
Running, temperature switch 7 controls powering on of PTC fin 5 by high voltage connector 4, also can control and high voltage connector 4 simultaneously
The relay 6 of coils from parallel connection of coils, thus control high temperature alarm circuit.Under normal circumstances, electric heating wind passes through low-voltage direct circuit controls
The operation of internal heat dissipating blower fan, controls the adhesive of high voltage connector simultaneously, and high-voltage DC power supply 3 ensures that PTC fin 5 work carries
Heating load.Meanwhile, the Guan Bi of relay 6 can be supplied to an outside Continuity signal by high temperature alarm circuit, represents that electricity adds
Hot internal work is normal.Under abnormal conditions, PTC fin 5 heat dissipates does not goes out, and after continuous heating, temperature switch 7 will disconnect,
And high voltage connector 4 is disconnected, and then the high voltage supply of PTC fin 5 is just disconnected, PTC fin 5 quits work.With
Time, relay 6 disconnects, and high temperature alarm circuit becomes the state of disconnection, in client can judge electric heating wind according to this signal
Portion's whether high temperature alarm.
Embodiment described above, the simply one of this utility model more preferably detailed description of the invention, the skill of this area
The usual variations and alternatives that art personnel are carried out in the range of technical solutions of the utility model are intended to be included in guarantor of the present utility model
In the range of protecting.
