濟南變頻器維修：軟啟動器有許多的維護作用，如果流、過電壓、過壓保護這些。隨之工控自動化水平的不斷提升，軟啟動器也獲得了十分普遍的運用。
Jinan Inverter Maintenance: Soft starter has many maintenance functions, if current, overvoltage, overvoltage protection. With the continuous improvement of industrial control automation level, soft starter has also been widely used.
變頻器造成漏保跳閘原因這由于軟啟動器的輸出波型帶有高次脈沖電流,而電動機及軟啟動器與電動機間的電纜線會造成泄露電流,該泄露電流比直流驅(qū)動器電動機時變大很多,因此造成該狀況。
The reason of leakage protection tripping is that the output waveform of soft starter has high pulse current, and the leakage current is caused by the cable between the motor and soft starter. The leakage current is much larger than that of the DC driver motor, so this situation is caused.
變頻器操作輸出側(cè)的漏電流大約為工頻操作時的3倍多,外加電動機等漏電流,選擇漏電保護器的動作電流應(yīng)該大于工頻時漏電流的10倍。使用變頻器的地方不適合采用具有漏電保護功能的保護開關(guān)。
The leakage current of the output side of the converter is about three times as much as that of the power frequency operation. When the leakage current of the motor is applied, the action current of the leakage protector should be 10 times as much as that of the power frequency operation. Where the frequency converter is used, it is not suitable to use the protective switch with leakage protection function.
由于變頻器的輸出存有高次脈沖電流，要不是選用的專用型變頻電纜和變頻電動機，那麼泄露電流是難以避免的，通常就會超出30mAh，使漏電保護器跳電。
Because of the high pulse current in the output of the converter, it is inevitable that the leakage current will exceed 30 mAh and make the leakage protector jump if it is not for the special converter cable and motor.
