Application
During compensating reactive power, the capacitors will be influenced by harmonic waves, closing surge, operating over-voltage and etc, and may lead capacitors being damaged or power factor decreasing, consequently series-connected reactors shall be used to connect in front of capacitors, to restrict harmonics, protect capacitors, prevent the influences of harmonic voltage, current or surging voltage/current, improve power factor, extend service life of capacitors.
Model and implication
Normal ambient?condition?
Altitude: ≤ 2000m
Working temperature：-25~55℃
Relative humidity: ≤90%
Mounting site has not fire risk, explosion, water?flood, strong chemical corrosion and etc.
Structure?
This product divided into two types: three-phase, single phase, dry type iron core.
The iron core made of high quality cold rolled silicone steel sheet, sheared by high speed punching machine, without furs, even, good piled, to ensure low temperature rise low noise during operating.
Coil made of good insulated conductors, wound by special machine: flat, smoothly, good looking.
During assembling, all clamps are provided with anti-corrosion treatment, the critical clamps made of non-magnetic material, then preheating on oven, vacuum immersed, make coil and core form a tight body, this can reduce temperature rise and noise, improve quality factory and eliminate harmonics.
Outline of reactor has referred to standard panels, small size, easy to connect with cables, save cost.
