| 正确使用变频器的注意事项 Proper use of the frequency converter's attention 1、环境温度对变频器的使用寿命有很大的影响。环境温度每升10℃，则变频器寿命减半，所以周围环境温度及变频器散热的问题一定要解决好。 Ambient temperature has a great effect on the life of the frequency converter. Per liter 10 ℃, environment temperature converter longevity by half, so the surrounding environment temperature and the inverter heat dissipation problem must be solved. 2、正确的接线及参数设置。在安装变频器之前一定要熟读其手册，掌握其用法、注意事项和接线;安装好后，再根据使用正确设置参数。 Correct wiring and parameter setting. Before installing the converter, be sure to read the manual and master its usage, notes and wiring. Once installed, the parameters are set according to the correct setting. 3、注意转速与扬程的关系。电机的选择及其最佳工作段是比较重要的问题。如果变频器长时间运行在5HZ以下，则电机发热成了突出问题。 Pay attention to the relationship between speed and lift. The choice of the motor and its best working segment are important issues. If the converter runs below 5HZ for a long period of time, then the heat of the motor becomes a prominent problem. 4、V/f控制属于恒转矩调整。而矢量控制使电机的输出转矩和电压的平方成正比的增加，从而改善电机在低速时的输出转矩。 V/f control is a constant torque adjustment. The vector control increases the output torque of the motor and the square of the voltage, thereby improving the output torque at low speed. 5、若系统采用工频/变频切换方式运行，工频输出与变频输出的互锁要可靠。而且开停泵、工频/变频切换都要停变频器，再操作接触器。由于触点粘连及大容量接触器电弧的熄灭需要一定时间，上述切换的顺序、时间要考虑周全。 If the system is running in the mode of operator frequency/frequency conversion, the interlock of the output and frequency output is reliable. In addition, the pump, operator/frequency converter switch must stop the converter and then operate the contactor. Due to the need for a certain amount of time, the order and time of the switch should be considered. |
