Improve electrical equipment power factor

First, the use of frequency conversion energy-saving equipment. With the development of China's frequency conversion energy-saving equipment, frequency conversion energy-saving equipment is more and more advanced, and many high-voltage, low-voltage and large-capacity frequency conversion energy-saving equipments have been developed. It realizes the variable frequency soft start, reduces the impact on the power grid, and can save about 25% of electricity.

The second is the use of compensation devices, both automatically adjusted electrostatic capacitors and automatically adjusted camera sets.

The third is to use low-voltage motor full-phase control technology. Its advantage is that it automatically adjusts the output power of the motor when dragging the load light load and heavy load, so that the motor can achieve the best power saving purpose, and can save about 15%. The fourth is to adopt a green lighting system. Through these technical measures, the power factor of the cement enterprise has been greatly improved, the reactive power demand has been reduced, and the loss of active power has been reduced.

Reasonable arrangement of production order:

The production equipment of cement is usually a high-power motor. The load is large during start-up and operation. Frequent fluctuations in the voltage of the power supply line often affect the quality of the power supply and affect the production of cement. Therefore, a reasonable order of equipment startup must be strictly implemented in cement production. In general, the first is grinding, then the packaging, and finally the feeding system. The starting interval of these three links must be more than 5 minutes, which can effectively ensure the stability of the voltage and improve the utilization of electrical energy resources. At the same time, it is necessary to strengthen scientific management, strengthen the training of grinding machine workers, learn to listen to the grinding sound, adjust the feeding amount according to the grinding sound, match the feeding amount with the grinding body, keep the feeding amount relatively stable, and strengthen the maintenance of the equipment. Maintenance to keep the mill running safely.
