Shunt reactor
-
- Commodity name: Shunt reactor
- Commodity ID: 1362032616638402560
- 类型: Power distribution/switching
- 品牌: Capni
Brand: Zhiyuan New Energy Description: This series of harmonic-resistant reactors is primarily designed to complement 0.4kV system power capacitors, improving the power factor of power systems. They effectively suppress higher-order harmonics in the power grid, reduce overloads on capacitors caused by harmonics, and prevent harmonic amplification. These reactors play a crucial role in ensuring the safe operation of capacitors, enhancing the waveform of network voltage, improving power supply quality, and promoting the safe and economical operation of the power grid. They are suitable for reactive power compensation and harmonic filtering applications involving 3rd, 5th, 7th, 11th, and 13th harmonic loads.
1. Introduction
This series of harmonic-rejection reactors is primarily designed to be used with power capacitors in 0.4kV systems. They help improve the power factor of power systems, effectively suppress higher-order harmonics in the grid, reduce overloading of capacitors caused by harmonics, and prevent harmonic amplification. These reactors play a positive role in ensuring the safe operation of capacitors, improving the waveform of network voltage, enhancing power supply quality, and promoting the safe and economical operation of the power grid. They are suitable for reactive power compensation and harmonic filtering applications involving 3rd, 5th, 7th, 11th, and 13th harmonic loads.
