3 phase power reactor for capacitor

タイトルまたは説明

.Purpose

With the wide use and development of the power electronics technology,power supply system caused a number of non-linear loads, such as low-voltage low-capacity appliances and high-voltage high-capacity equipment such as industrial rectifier equipment, frequency conversion equipment, which will make current, voltage generate distortion, thus causing grid harmonic "pollution."  the harmonic pollution has seriously affected the reactive power compensation equipment for safe operation. parallel capacitor and reactor with appropriate reactance rate connected in series is to solve harmonic amplification and protect capacitor, it is a effective and feasible method,the main function of our 3 phase reactor is to suppress higher harmonics and capacitor inrush current,to prevent capacitors from harming by harmonics.

1,The ambient air temperature must not exceed +40 °C, but also in the 24 h period the average temperature does not exceed +35 °C,the ambient air temperature not lower than -25 °C.
2,Relative Humidity: clean air, at a maximum temperature of +40 °C, the relative humidity must not exceed 50%. At a lower temperature allows a greater relative humidity. For example, when the temperature is +20 °C the relative humidity allowed be 90%,but this conclusion should take into account changes in temperature may occasionally cause some condensation.
3,Installation location altitude does not exceed 2000 m.
4,Environmental Requirments:Relative strong vibrations and shocks are not allowed, the existence of gas and conducting medium which will corrode metals and destroy insulation are not allowed; no explosion meduim; no conducting dust; no raining and snowing and mycete.
5,The installation location vibration conditions: Vibration frequency range of 10 ~ 150 Hz, the maximum vibration accelerated speed is less than 5 m/s2.
