200型18盘捻股机变频改造

Frequency conversion transformation of 200 type 18 reels strander

针对老式200型18盘捻股机存在故障率高、电机内部电流加大、维修成本较高,影响生产效率等问题,利用变频器对老式捻股机进行改造,充分利用变频器的软启动功能和防堵转功能,并对原有控制电路进行优化。变频器改造选用E5-H系列变频器,功率为11 k W,并对变频器参数进行设置。调试过程中启用变频器的转矩提升功能,提升了捻股机性能,降低了故障率,实现了老设备的改造利用。

Aiming at the existing problems of old-fashioned 200 type 18 reels strander, such as high failure rate, current increase inside the motor, high maintenance cost and affecting production effecieney, to use frequency converter to transform old-fashioned strander, make full use of soft-start function and anti-blocking function of the frequency converter, and opti- mize original controlling circuit. E5 -H series converter is selected to transform converter, the power is 11 kW, and set converter parameters. The torque increase function was started to use during the debugging, improve the strander property, decrease the failure rate, and accomplish the transformation and utilization of old device.
