High-voltage inverters are electrical equipment used in high-voltage power systems, which have the function of regulating voltage, frequency and power. Its main application areas include but are not limited to the following eight aspects:
1. Oil and gas drilling industry: Inverters are used in the oil mining industry, mainly for motors of load types such as oil extraction machines (nodding machines), water injection pumps, submersible pumps, oil pumps, gas compressors, etc., mainly for motor energy saving.
2. Metallurgical industry: The application of high-voltage inverters in the metallurgical industry mainly includes rolling mills, coilers, fans, slurry pumps, etc. for plates and wires, mainly for motor energy saving.
3. Power industry: The power industry is also one of the important application areas of inverter products. Inverter products are mainly used to change the amount of coal, powder, water, etc. to adapt to the changes in load, and finally achieve the purpose of saving energy and improving the control process level, which 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 and sewage treatment systems in public 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: 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. Frequency converter products are mainly used in blowers, crushers, belt conveyors, exhaust fans, rotary kilns and other equipment in the building materials industry.
7. Coal industry: Frequency conversion speed regulation technology can play a good energy-saving role in mine hoists in the coal industry. At present, developed countries have widely used frequency converters for speed regulation of belt conveyors or starting control of belt conveyors, fan speed regulation (including main fans and partial fans) and water pump speed regulation. Equipping the motors in the above equipment with frequency converters can not only improve the transmission function, but also save energy.
8. Medical equipment: In the medical field, high-voltage inverters are used in high-voltage power supply systems of medical imaging equipment (such as CT, MRI, etc.) and medical devices to provide stable power supply and precise voltage regulation to ensure the safety and stability of medical equipment.
In general, high-voltage inverters are widely used in power systems, industrial production, power testing, equipment driving, energy management and other fields, which are of great significance to improving energy utilization efficiency, optimizing production processes and ensuring stable operation of power systems.
