1. The input power of the high-frequency machine is lower than the input power of the power frequency machine. The power frequency machine generally uses thyristor pulse rectification in the input circuit. If the generator is connected to the front, the capacity of the generator must be at least 2 to 3 higher than the capacity of the power frequency machine. Times. If it is a single-phase low-power industrial frequency machine, the capacity of the generator must be at least 5 times the capacity.

The input power factor of any high-frequency machine can be achieved. The capacity of the front-mounted generator is theoretically the same as that of the power-frequency machine, which reduces investment and floor space.
2. The power consumption of the high-frequency machine itself is small. When the power frequency machine and the high-frequency machine have the same capacity, the annual power frequency machine consumes 50,000 kWh more than the high-frequency machine!
3. The external interference of the high-frequency machine is small. The power frequency machine generates electrical noise and mechanical noise. Electrical noise affects the stability of the machine, mechanical noise affects people's physical and mental health, and reduces work efficiency. The high-frequency machine is a frequency that is inaudible to the human ear, which makes the working environment quiet. Due to the input power factor of the high frequency machine, the external interference is almost zero.
4. The high-frequency machine is small in size and light in weight. The power frequency machine has large volume and weight due to the output transformer and the low-frequency components such as the inductor and capacitor.
5. The high-frequency machine has strong adaptability to the power grid. The power frequency machine is not easy to adapt to the change of the input voltage; the high-frequency machine even adapts to the larger change of the input voltage, which greatly prolongs the life of the battery.
6. The high-frequency function attenuates the parallel circuit to almost zero. The parallel connection of the power frequency is the direct parallel connection of the transformer, and the direct parallel connection of the transformer is the most easy to generate the circulation, and the path of the circulation is unimpeded; the high-frequency machine has no output transformer. It can be seen that the obstacle voltage difference is not formed in the circulation path here, and the power frequency machine will form a large circulation in this case.
In short, the high-frequency machine can not only completely replace the power frequency, but also has the advantages that the latter does not have.
High frequency machine is better than power frequency machine
