First, an overview
In reactive power compensation, capacitor is often affected by harmonic current or harmonic voltage. Caused by capacitor damage and reduce power factor, therefore require the installation of Ruihuang series reactor in front Ruihuang capacitor, to resist and absorb the corresponding harmonic, protect the safe operation of capacitor, avoid harmonic voltage, excitation amplification effect, improve the quality of the power grid, improve power factor of the system.
Two, the implementation of standards
5346-1998 JB "series reactor"
Three, environmental conditions
1, the ambient temperature of -25 to +45 DEG C; relative humidity is less than or equal to 90%RH.
2, altitude is not more than 2000m.
3, no severe vibration and shock, no inflammable and explosive dangerous goods, no conductive dust.
4, around should have good ventilation conditions, such as installed in the cabinet, should exhaust facilities.
5, temperature resistant grade H grade (180 degrees C) above.

Four, technical indicators
1, can be used for 400V, 660V, 690V and other systems.
2, reactance rate XL/XC = 6% (204Hz); 12% (144Hz) and other different reactance rate requirements.
3, rated insulation level 3kv/min.
4. The limit temperature rise of each part of the reactor, the winding is not more than 80K, the iron core is not more than 95K.
5, reactor noise is not greater than 45dB.
6. The difference of any two phase reactor is not more than 3%.
7, can be in the power frequency and harmonic more than 1.35 times the rated current under the long-term operation.
