【正文】 Even more faces the user, further enhances the workability and Maintainability: Turns towards, the featherweight development small, as well as reduces the cost and so on. (2) Intellectualization Including two aspects: Reduces the hardware as far as possible, realizes the hardware software。 Reduces frequency changer own loss, the realization high efficiency。t reduce, the electrical machinery power factor can obtain the enhancement. B:Moves is reliable, is stable. In the system core part frequency conversion velometer itself reliability is very high, in the ordinary circumstances may the longterm usage 100,000/Above h. The system also selects the soft start method, does not have the electrical impact, does not pollute the electrical work, moreover frequency changer bringing owes presses, the pressure, the overflow, the overload, superheat as well as loses speed and so on each kind of protection function. The system adopts damping filter processing to the pipe work fluctuation of pressure, the water supply constant pressure precision is high, usually can control in the scope. C:The structure is simple, the operation is simple. The installment control system uses the integration rate to be high, necessary plan nimble diverse, obtains water pump movement each kind of bination by the programmable controller. The velocity modulation scope is broad, to water volume change adaptiveness. D:The service life is long, the automaticity is high, does not need the human to safeguard, maintains the quantity to be few. Above system the effect is remarkable in the actual application, if brings in PLC and the frequency changer the programmer the function integration, potential bees some specialpurpose frequency changers, such system reliability and the toughness big enhancement, the application is simpler, the system total cost also can drop. May foresee: The future frequency conversion technology will be able to develop to the below direction: (1) high performance Thus including internal leveling circuit, the contravariant electric circuit all use the high frequency PWM electric circuit to cause the input, the output all are sine waves。 From the hardware interface considerations, Single Chip Micro controller circuit slightly plex。 Transducer in the water control system applications Currently, the water level control in a large part of the electrical pumps are not towing gear shift system, no gear shift most of the electrical energy consumed in the water supply to the frequent changes in the pumps stopped. This not only makes the electrical work in inefficien
