Inventory of 7 major application areas of high-voltage inverters

Seven major application areas of high-voltage inverters Inverter is an electric energy control device that converts industrial frequency power into another frequency by using the on-off function of power semiconductor devices.

1.Oil and gas drilling industry:

Inverters are used in the oil mining industry, mainly for motors of load types such as oil drilling machines (droving machines), water injection pumps, submersible pumps, oil pumps, gas compressors, etc., mainly for the purpose of motor energy saving.

2.Metallurgical industry:

The application of high-voltage frequency converters in the metallurgical industry mainly includes sheet and wire rolling mills, coilers, fans, slurry pumps, etc., and the main purpose is to save energy on motors.

3.Power industry:

The power industry is also one of the important application areas of frequency converter products. Frequency converter products are mainly used to change the amount of coal, powder, water, etc. to adapt to changes in loads, ultimately achieving the purpose of saving energy and improving the level of control technology. It is of great significance to the energy saving, consumption reduction, emission reduction, safety and stable operation of thermal power plants.

4.Water supply:

water supply and drainage systems, sewage treatment systems, etc. in common projects. These devices are mainly fan and water pump motor loads. The energy-saving effect of using high-voltage inverters is very outstanding, and usually about 30% of electricity can be saved.

5.Petrochemical industry:

Petrochemical industry is the artery of national economic development. Frequency converters are mainly used in various pumps, compressors and common engineering in oil processing (refining) to achieve the purpose of energy saving and control process level.

6.Building materials industry:

The building materials industry is an important material industry in my country. Its products include three categories: building materials and products, non-metallic minerals and products, and inorganic non-metallic new materials. Inverter products are mainly used in blowers, crushers, belt conveyors, exhaust fans, rotary kilns and other equipment in the building materials industry.

7.Coal industry:

Variable frequency speed regulation technology is applied to mine hoists, showing significant energy-saving potential. At present, developed countries have widely adopted frequency converters to adjust the speed of belt conveyors, control the start of conveyors, adjust the speed of fans (including main and auxiliary fans), and manage the operation of water pumps. In these systems, installing frequency converters on motors can not only improve transmission efficiency, but also achieve significant energy-saving effects.
