Multichannel is exported ozone generation power supply synchronously

Technical field

The utility model relates to a kind of multichannel and exports ozone generation power supply synchronously, in large-scale ozone generator.

Background technology

In recent years. ozone technology is in medical science. food, sewage disposal, but be used widely in fields such as tap water sterilization and disinfection. when ozone is used for water treatment. secondary pollution is few. represented good prospects for application. the economy of ozonizer operation. be the bottleneck of its popularization. power consumption then is wherein most important parameter. compares with the power frequency ozonizer., high frequency ozone generator has compact construction, ozone concn height and low power consumption and other advantages. therefore. the design of the high frequency inverter of ozonizer seems the particularly important .20 end of the seventies in century. because the integrative development of microelectronics and power electronics. make the turn-off thyristor GTO(Gate Turn-off Thyristor of big electric current), devices such as insulation canopy bipolar transistor IGBT and SPM IPM have obtained development at full speed.Having introduced with IGBT in the paper of " the large-scale ozone generator IGBT inverter power circuit relate to analyze " of He'nan University's Electrical and Mechanical Engineering College is core devices, the inverter of design large-scale ozone generator, introduced the gate driver circuit principle of inverter master loop, pwm control circuit, IGBT, though this design has reduced power supply power consumption, but existing large-scale ozone generator is generally at 5kg/hr ~ 100kg/hr, and power is at 50kw ~ 500kw.When power is excessive, be easy to cause discharge between dielectric impedance reactor inner high voltage anode and damage and produce great undesired signal.Therefore, proposing the synchronous power supply of ozonizer of exporting of a kind of multichannel is necessary.

Summary of the invention

The purpose of this utility model provides a kind of multichannel and exports ozone generation power supply synchronously, and it can synchronously control to the IGBT module with setting pulse, realizes that multiple output high voltage is synchronously strict.

Multichannel of the present utility model is exported ozone generation power supply synchronously, comprise the multirouting rectified three-phase circuit, power factor correction, the IGBT module, resonance reactor, the current supply circuit that the high voltage step-up high-frequency transformer connects successively, it is characterized in that: further comprise a control module, described control module is connected with an IGBT driver module respectively through the optical fiber transceiver module, described IGBT driver module is connected with the IGBT module of current supply circuit respectively, and the output terminal of the high voltage step-up high-frequency transformer of described current supply circuit is connected with a dielectric impedance ozone reactor.

Below in conjunction with drawings and Examples the utility model is described further.

As shown in Figure 1, the utility model provides a kind of multichannel to export ozone generation power supply synchronously, comprise multirouting rectified three-phase circuit 3, power factor correction 2, IGBT module 1, resonance reactor 4, the current supply circuit that high voltage step-up high-frequency transformer 5 connects successively, it is characterized in that: further comprise a control module 7, described control module is connected with an IGBT driver module respectively through optical fiber transceiver module 9, described IGBT driver module is connected with the IGBT module of current supply circuit respectively, and the output terminal of the high voltage step-up high-frequency transformer of described current supply circuit is connected with a dielectric impedance ozone reactor 6.In present embodiment, as shown in the figure, we are example with three road current supply circuits, are noted that this way here not as limit, and it can be provided with multichannel as required, and principle of design is similar.As seen from the figure, be provided with three anode high voltage joints in the described medium impedance ozone reactor 6, negative electrode links to each other altogether, and the utility model utilizes a main control module that control signal is synchronously controlled to the IGBT module by fiber optical transceiver, and is synchronously strict to realize the output high pressure.

In order to allow those skilled in the art better understand the utility model, below principle of design of the present utility model is described further, ozonizer power supply of the present utility model is mainly ozone reactor the high voltagehigh frequency power supply is provided, power supply forms the dc bus high pressure by three-phase electricity after rectification module 3 and power factor correction module 2, magnitude of voltage is the peak value UP of Uin (input voltage).Dutycycle, frequency and the power density (PDM) of this power supply may command output voltage.This power density refers to the high frequency electric source discontinuous operation, and the working hour accounts for the ratio in whole cycle; When adjusting to circuit resonance point, 6 equivalences of ozone reactor electric capacity are elementary to high voltage high frequency transformer 5, and with resonance reactor 4 resonance take place, the formation first step is boosted, after again through high-frequency transformer 5 secondary boosters that boost, form the high-frequency and high-voltage of 4KV ~ 10KV, its operating frequency is in that (waveform of 500HZ ~ 20KHZ) as shown in Figure 2.

Owing to the output control signal will be transferred to each driver module meeting because each module can't be synchronously strict apart from reason and signal high-low pressure isolating problem by electric wire, and long line synchronous signal transmission can be disturbed easily, the utility model not only solves the long distance transmission problem by the optical fiber transceiver module and also solves signal high-low pressure isolating problem, is not subjected to electromagnetic interference simultaneously.Wherein optical fiber not only can the transmitting synchronous actuate signal, and can be with each module overcurrent, overload, and excess temperature signal, and voltage, electric current, temperature signal passes through Optical Fiber Transmission.

The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
