Abstract
The utility model is an omniseal high pressure transducer with a heat exchanger relating to an electricity shifter widely used in industry and agriculture, and the utility model is applicable to timing of generator. The heat exchanger is provided in the machine cabinet or the outer portion of high pressure transducer, the machine cabinet and a heat receiver of the heat exchanger are omniseal, the environment and the portion of the high pressure transducer which is used to radiate by the heat exchanger only have heat change and don't have the exchange of air in order to avoid flour dust, aggressive gas and effect of ventilating and radiating caused by high temperature environment. If the high pressure transducer is a traditional high pressure transducer with a transformer mechanism, the transformer can be insolated, and the heat exchanger can not radiate to the transformer to reduce the electricity consumed by radiating. A temperature control sensor is arranged in the route of circular wind path in the machine cabinet and can regulate the refrigerating capacity of heat exchanger or the number of operational machine unit according to high and low temperature of circular wind.
Description
Technical field the utility model is a widely used power-converting device in worker, agricultural, is used for electric machine speed regulation.
Background technology is present, and high voltage converter has been widely applied at needs and adjusted operating mode and energy-conservation production link, and for example ZL95119585.9 patent of invention disclosed " a kind of high-voltage power transform method and converting means thereof " has obtained extensive use.But radiating mode still all is to adopt traditional mode, promptly new wind is discharged and sucked to the heat in the high voltage converter, when this method is used in the higher area of ambient temperature, not only increased the required energy consumption of dispelling the heat with blower fan, sometimes it is bad also can radiating effect to occur, the phenomenon that built-in temperature is higher.And temperature is higher for a long time, and it is bad to dispel the heat, just the main cause of the lifetime of power electronic device.Although someone is in order to improve the effect of ventilation and heat, in the aeration radiation system of high voltage converter, increased water cooling plant, but if reach effect with refrigeration, the volume of this water cooling plant is very big, cost is very high, and the operation energy consumption of this water cooling plant is very high, and it is impossible installing the water cooling plant with refrigeration additional for high voltage converter so; Simultaneously for fear of dust particularly charged corpuscle and mordant gas enter in the machine, also the dedusting protector must be installed, not only increased cost, also increased operation energy consumption, sometimes or even can't realize.
The utility model has given the conventional high-tension frequency converter a revolutionary innovation, on the high voltage converter rack or at the inner heat exchanger of installing of high voltage converter rack, its thermoreceptor is contained on the path of circulation wind path in the machine, the radiator of heat exchanger is installed in outside the rack or outdoor being convenient to dispelled the heat, even ambient temperature has been unfavorable for conventional heat radiation, the utility model can guarantee that still the heat radiation of high voltage converter rack inside is good.And reduced the requirement to environment for use, use in the area that is specially adapted to the area that ambient temperature is high and dust is higher, the gas that is corrosive.Because rack is totally-enclosed, not with environment ventilation, dust and corrosive gas are difficult for entering rack, make long-term the maintenance well of electric property of device, have reduced the cost that the dedusting protector is installed, and have also saved the energy consumption of operation.Main is: because employing is the refrigeration mode heat exchanger, high voltage converter rack temperature inside can be controlled in the temperature range that is fit to the power electronic device operate as normal, prolong the useful life of power electronic device and overload capacity is protected.
The summary of the invention the purpose of this utility model is the shortcoming that overcomes above-mentioned conventional high-tension frequency converter, a kind of high voltage converter of hermetically sealed band refrigeration mode heat exchanger is provided, this device can greatly improve radiating effect, make the most effective of heat radiation, and the temperature in the high voltage converter is controlled in the temperature range that is fit to the power electronic device operate as normal, prolonged the useful life of power electronic device and overload capacity is protected.Be specially adapted to the high and dust higher area use of ambient temperature.And reduced the cost that the dedusting protector is installed, also saved the energy consumption of operation.
