For any type of motor product, there will be a technical condition of the product, in which the efficiency and power factor of the motor will be determined.And other performance indicators parameter values to make specific provisions Customized AC power Motor should also take these factors into account.
Power factor refers to the ratio of active power to apparent power of ac circuit.Under certain voltage and power, the higher the efficiency is, the better the power generation equipment can be fully utilized.To put it simply, each motor system consumes two large powers, active power and reactive power.Power factor is the ratio of active work to total power, expressed as a decimal number.The higher the power factor is, the greater the ratio of useful work to total power will be, and the more efficient the system operation will be.
The motor in the power grid is an inductive load, and the inductive equipment needs to absorb not only active power but also reactive power into the power system during operation.Therefore, the installation of shunt capacitor reactive compensation equipment in the grid can provide the reactive power consumed by compensating the inductive load and reduce the reactive power provided by the lateral inductive load of the grid power supply and transmitted by the line.Due to reducing the flow of reactive power in the grid, the power loss caused by transmission of reactive power in transformers and bus lines in transmission and distribution lines can be reduced, which is the benefit of reactive power compensation.
From the point of view of the power supplier and the power user, the high power factor can reduce the power loss, and at the same time can effectively reduce and control the input of the compensation component in the supply system.For motor users, a higher power factor can reduce the voltage drop to ensure the stability of motor operating voltage;From the perspective of system safety analysis, the interference of compensation elements may generate interference harmonics, cause abnormal power waveform, and cause adverse effects on the electrical equipment, especially for high-voltage and high-power motors, it is very possible to have axial current problems.
Necessarily improve the power factor of the economic benefits of the country's energy use, the enterprise play an effective role in promoting, is to ensure that the power system power quality, voltage quality, reduce network losses, and safe operation of the indispensable conditions should take corresponding
