山东变频器维修：变频器和软启动器其实是俩种完全不同用途的产品。变频器主要用在电机调速的地方，变频器拥有软起动器以及其他启动器的性能的同时，在启动特性上较其他的启动器装置也有很大的优势。那么相比之下，变频器的优势有哪些呢?

Frequency converter maintenance: inverter and soft starter are two kinds of products of different uses. Frequency converter is mainly used in the place of motor speed regulation. Frequency converter has the performance of soft starter and other starters. At the same time, it has great advantages over other starter devices in starting characteristics. In contrast, what are the advantages of the converter?

1、采用变频器控制的电动机具有良好的动态、静态性能。

1. The motor controlled by frequency converter has good dynamic and static performance.

2、轻载或空载条件下，或启动期间采取减载卸载等措施时，变频器容量可以比电动机容量小。

2. Under the condition of light or no load, or the measures of unloading or unloading during start-up, the capacity of frequency converter can be smaller than that of motor.

3、用变频器拖动多台电动机启动时，即使被拖动电动机的容量有较大差异，也不会影响其启动性能。

3. When several motors are driven by frequency converter to start, the starting performance will not be affected even if the capacities of the motors are quite different.

4、启动转矩大，功率因数高。因为电动机的功率因数与工作频率有关，在电动机低速运行时工频电源下的功率因数远低于低频电源下的功率因数。变频器可以控制电动机从低频起步，且在整个启动过程中在接近额定电流的条件下始终保持比较高的功率因数和接近额定转矩的输出转矩。

4. High starting torque and high power factor. Because the power factor of the motor is related to the working frequency, the power factor of the power-frequency power supply is much lower than that of the power factor of the low-frequency power supply when the motor is running at low speed. The frequency converter can control the motor to start at low frequency, and maintain a relatively high power factor and output torque close to rated torque throughout the starting process under the condition of close to rated current.

5、启动完成后，对电动机而言，需要一个供电切换过程，由变频器供电切换到电网供电。在整个过程中会出现诸如变频器安全、电流冲击。

5. After the start-up is completed, for the motor, a power supply switching process is needed, which is from the converter power supply to the grid power supply. In the whole process, there will be such as frequency converter safety, current shock.
