Abstract: Handling faulty power capacitors should be done by disconnecting the capacitor's circuit breaker, pulling apart the two isolation switches of the circuit breaker, and discharging the capacitor bank through the discharge resistor. After the capacitor bank is discharged through the discharge resistor (discharge transformer or discharge voltage transformer), since some residual charge is not discharged at one time, an artificial discharge should be performed...

Abstract: Intelligent power capacitors have built-in switching switch modules. The switching switch module is composed of a thyristor, a magnetic holding relay, a zero-crossing triggering conducting circuit and a thyristor protection circuit, and realizes a "zero switching" of the capacitor, ensuring no surge current impact during the switching process, and no operation overvoltage. The switch module responds quickly and can be operated frequently...

Abstract: Power capacitors are used in capacitors for power systems and electrical equipment. Any two metal conductors separated by an insulating medium constitute a capacitor. The size of the capacitor capacitance is determined by its geometry and the characteristics of the dielectric between the two plates. When the capacitor is used under AC voltage, it often uses its reactive power. The rate indicates the capacity of the capacitor, and the unit is lacking or lacking...

Abstract: After long-term high-speed development, China's power supply and power grid construction have reached a relatively complete level, and the relevant investment amount is at a historical high level, and the future growth momentum is slowing down. In the power supply segment, the total installed capacity of the 13th Five-Year Plan declined, and the focus shifted to the adjustment of energy structure. The clean energy consumption became a prominent problem. In the power grid, equipment redundancy is increased, the investment in the two networks is slowing down, and the increment is at both ends...

Abstract: In recent years, with the development of the energy Internet, the power and electrical equipment industry seems to be somewhat turbulent. The efficiency of electrical product manufacturers is good and bad, and all fields are in line with the development of the times. The transformation and upgrading of the electrical industry is not only these, but how should the electrical equipment industry grasp the new development trend...

In recent years, the development of the domestic power capacitor industry has been extremely rapid, and the quality and quantity of products have been greatly improved. A considerable number of advantageous enterprises have begun to win the international market and achieved good performance. With the rapid development of the power industry, With technological advancement and the strengthening of reactive power compensation and energy-saving loss management, power capacitor manufacturing enterprises have encountered unprecedented development opportunities to rapidly expand the market for power capacitors. At the same time, it has also triggered a large demand for power capacitors in many fields. The following is an analysis of the development trend of the capacitor industry in 2017.

China's capacitor market is the largest market in the world. At present, both the manufacturing level and the reactive power compensation demand for power system operation have reached the time when the capacitor manufacturing industry is required to carry out the concept of conversion and move forward. Otherwise, it will inevitably Thanks to the strong impact of big international companies, both the capacitor manufacturing industry and the power system users should be given sufficient knowledge. The following is an overview of the 2017 capacitor industry and its current status.
