Yet, there is following shortcoming in above-mentioned existing track traffic auxiliary power supply system, contactless switch belongs to mechanical device, the switch motion of mechanical device make contactless switch open and disconnect between switch speed slow, need the regular hour, and the fault rate height, the longevity of mechanical switch, reduce power supply reliability, and then influenced the normal use of air-conditioning, illumination even load on the car.
The utility model content
The utility model is to make for the problem that overcomes above-mentioned existence, and the utility model purpose is, obtains the light rail vehicle auxiliary inverse power supply of high reliability.The utility model and the structural identical point of existing light rail vehicle auxiliary inverse power supply parallel device are, all be to constitute by two covers auxiliary inverse power supply in parallel, every cover auxiliary inverse power supply is made up of the peripheral circuit of subordinate inverter, control circuit, realization signal detection, conversion, direct current energy is converted to AC energy, powering load.Difference is, the interchange outgoing side of the auxiliary inverse power supply that two covers are identical, directly connect by lead and carry out parallel operation, the method for this realization parallel connection has replaced traditional light rail vehicle auxiliary inverse power supply parallel device and has connected the method for carrying out parallel connection by contactless switch.
The operation sequential of the utility model control method:
After auxiliary inverse power supply parallel device starts, the control chip of two cover auxiliary inverse power supplies sends synchronizing pulse by optocoupler to the synchronous voltage signal bus respectively, two synchronizing pulses carry out " with " on the synchronous voltage signal bus, form a common synchronization pulse after the logic, this common synchronization pulse inputs to control chip through after the light-coupled isolation again, two cover auxiliary inverse power supplies detect outgoing current respectively simultaneously, one tunnel process light-coupled isolation is input in the control chip, after calculated signals and conversion are carried out through peripheral circuit in another road, obtain the aviation value of two cover auxiliary inverse power supply outgoing currents, the aviation value of this outgoing current is transported on the synchronizing current signal bus, and then the outgoing current aviation value is input in the control chip through light-coupled isolation.
After the control chip of two cover auxiliary inverse power supplies obtains above-mentioned common synchronization pulse and outgoing current aviation value respectively, with the common synchronization pulse is benchmark, the timer value zero clearing of being responsible for the control wave counting, make that the frequency of two cover auxiliary inverse power supply output voltages is identical with phase place, simultaneously, the difference of detected output current value and current average is carried out PI regulates, make that two cover auxiliary inverse power supply output voltage amplitude are identical, at this moment, frequency, phase place and the amplitude of two cover auxiliary inverse power supply output voltages are all identical, have realized the condition of directly moving with lead.
When an auxiliary inverse power supply fault, control chip blocks the drive pulse of fault inverter at once according to the control information of enrolling in advance, stops the operation of fault inverter, but load still can be powered by normal auxiliary inverse power supply, thereby has realized uninterrupted power supply; After the excision of fault auxiliary inverse power supply device, if load is overweight, system can send the overload alarm signal, and the control chip of the auxiliary inverse power supply of normal operation reduces load running by the control information of enrolling in advance, provides the failure-free power supply to load.
Compare with existing light rail vehicle auxiliary inverse power supply parallel device, the advantage of the utility model light rail vehicle auxiliary inverse power supply parallel device is, realized uninterrupted power supply, overcome that existing light rail car auxiliary power supply system is slow owing to the contactless switch switch speed that occurs of existence of expansion consumer unit, fault rate is high, the problem of power supply reliability difference, the reliability of total system is improved.
Description of drawings
Fig. 1 a kind of light rail vehicle auxiliary inverse power supply parallel device circuit diagram described in the utility model
The specific embodiment
At first the structure of described light rail vehicle auxiliary inverse power supply parallel device is described below.
The utility model is made of two covers auxiliary inverse power supply in parallel, and every cover auxiliary inverse power supply is made up of the peripheral circuit of subordinate inverter, control circuit, realization signal detection, conversion, direct current energy is converted to AC energy, powering load.Control chip can adopt digital signal processing chip (DSP), micro controller system and CPLD (CPLD).Peripheral circuit can adopt disclosed circulation detection and treatment circuit in the document " research of SPWM adverser control technology " (1028703 05-0081).The interchange outgoing side of the auxiliary inverse power supply that two covers are identical directly connects by lead and carries out parallel operation, and the method for this realization parallel connection has replaced traditional light rail vehicle auxiliary inverse power supply parallel device and connected the method for carrying out parallel connection by contactless switch.
Action to described light rail vehicle auxiliary inverse power supply parallel device describes below.
After auxiliary inverse power supply parallel device starts, two cover auxiliary inverse power supplies are respectively through light-coupled isolation, send synchronizing pulse to the synchronous voltage signal bus, two synchronizing pulses carry out " with " after the logic, on the synchronous voltage signal bus, form a common synchronization pulse, this common synchronization pulse inputs to control chip through after the light-coupled isolation again, with the common synchronization pulse is benchmark, the timer value zero clearing of being responsible for the control wave counting, make that the frequency of two cover auxiliary inverse power supply output voltages is identical with phase place.
