Series Reactor, Oil Power Transformer
Series reactor
Quality features:
In recent years, a large number of industrial semiconductor equipment has increased, and circuit harmonic problems have
are becoming more and more serious. In order to suppress various harmonics caused by high-order harmonics in the power system,
obstacles, and the automatic power factor adjustment panel (APFR) is regularly put in
It is recommended that you install a series reactor to reduce the current surge caused by the circuit.
Suppress current surges in circuits to extend the life of capacitors and electromagnetic contactors
life.
| Insulation and temperature | Dry type: H grade, coil temperature rise below 120℃ (resistance method) | ||
| Oil type: coil temperature rise 55℃ (resistance method) | |||
| Installation location | Indoor | ||
| Applicable temperature | -20~+45℃ (24-hour average ambient temperature below +35℃) | ||
| The maximum operating current | The maximum operating current is less than 120% of the rated current (when the reactor gas circuit contains the fifth harmonic current, it has a probability of The basic wave current should be below 35%, the resultant current effective value) | ||
| Capacity allowance difference | Rated capacity-5~+10% | ||

The capacitor is installed in a circuit containing harmonics - a 6% series reactor should be installed
Non-fixed input circuit - 6% series reactor should be installed
Circuits with higher fifth harmonics - 8% series reactor should be installed
Places with third harmonics such as electric arc furnaces - 13% series reactor should be installed
