High pressure rotor frequency converter, in the time choosing, is all generally that user provides load and the parameter of electric machine,Manufacturer is according to parameter specific design, because frequency converter internal structure is all by discrete component structureBecome, product integrated level is low, and make to manufacture every rotor-side variable frequency device and all will carry out primary production design,Time-consuming taking a lot of work.
In high pressure rotor frequency converter equipment, core component is copped wave module. Generally all use 1000The above IGBT of volt forms copped wave module. More than 1000 volts IGBT base in the marketThis is dependence on import all. High pressure rotor frequency converter copped wave module is selected 1200V/800A conventionally,These three kinds of 1700V/800A and 3300V/800A. The withstand voltage of frequency converter inner member is all complied withDesign according to the voltage at copped wave module two ends. In view of conventional IGBT model fewer, weHigh pressure rotor frequency converter can be divided into several different types according to the withstand voltage difference of copped wave moduleNumber. Rectifier small and exquisite volume, chopper, inverter, driver module. Communication detection mouldPiece is all incorporated in a casing, and the too fat to move filter reactor of volume, vacuum circuit breaker passes throughBusbar interface reserved on casing is connected in main circuit.
With reference to the low voltage frequency converter product on market, the main power electronic devices of low voltage frequency converterAll be integrated in a casing, according to different control requirements, user only need design once peripheralCircuit just can well be realized every control function, lower to user's technical requirement, also fullFoot the diversified demand of user. With reference to low voltage frequency converter product, we need to produce a kind of bodyLong-pending small and exquisite, the high pressure rotor frequency converter of programmable control, after product export, user only need to pressRequire a peripheral circuit of design just can realize every control function according to different control. Give userThe more space of selecting.
