Motor Network Frequency conversionem refers to the vexillum condiciones, cum C% extra onus intra X% ~ C% extra celeritatem post operationem, temperatus non excedat motricium calibration of liceat. Motricium potest esse intellexit a driving frequency converter diversis gyratoris celeritate et torque, ut ad aptet ad demanda onus mutatio. Frequency conversionem motricium communem, quod ex traditional sciurus, caveam motricium. Fere uti traditional motricium fan refrigerationem fan ad libertatem, et proficit motricium curvis velut corona repugnant munus. Quam ad ponere bonum frequency conversionem motor frequency converter. 1, the differential maintenance to ensure internal fault sensitive differential maintenance action, together to avoid external failure and the motor starting transient unbalance current caused by misoperation, join the frequency conversion motor maintenance device, including differential maintenance frequency and frequency conversion backup maintenance, and then gives the frequency conversion motor running perfect maintenance. 2, backup maintenance for variable frequency operation, have corresponding backup maintenance reflect the various abnormal operating condition of the motor, the setting of demand has a quick break over current, over current and negative sequence maintenance maintenance function, used to detect the locked-rotor and turn-to-turn fault of the machine. Tergum sustentationem realis-vicis deprehendatur frequency conversionem motricium operating frequency, et calculandum correspondentes current RMS, discriminant conditione motricium. Cum electrica mechanicus frequency startup, correspondentes sustentationem functio exits, originale Heald modo eligere motricium praesidio fabrica perficere tergum sustentationem. When the motor frequency conversion operation, if the attack turn-to-turn fault, fault fault current level and the attack time frequency, the size of the negative sequence current maintenance in order to progress to the sensitivity of turn-to-turn fault, set how much period of fixed value, detection of turn-to-turn fault under different frequency.
