High pressure air core reactor

Summary

UEG high pressure air core series reactor Americaelectrical production, with damping reactorcapacitor used and high pressure filter reactor, theproduct of design by analysis, new world computingsoftware product design, reasonable design,excellent quality, maintenance free and easy to mount.

* damping reactor: damping reactor and capacitorseries, can limit the transient parallel capacitorgroup switch transition process and the inrush current, compared with series reactor of the reactance value is low, but the voltage strengthrequirements are higher.

* filter reactor: harmonic filter can provide reactive power and harmonic filter in fundamentalfrequency. In the harmonic frequency required,harmonic filters in phase or phases impedance is very low, so the harmonic current will flow into thefilter and can not flow into the power grid. Usually each particular harmonic frequency of the filterneed to be installed separately, for the high frequency harmonic waves using broadband filter.Acor method to manufacture filter reactor and capacitor according to customer requirements specification. Harmonic filter reactor we can provide no load tap, the required frequency for more precise and accurate tuning.

* shunt reactor: capacitive shunt reactor is used to compensate for long distance transmission linegenerated during light load reactive power. Third winding shunt reactor is usually connected to the main transformer, circuit breaker to input or removal, up to a maximum of 36KV voltage class of 100MVA reactor.

* neutral grounding reactor: neutral grounding reactor is connected between the three-phase systemneutral point and the ground, its purpose is tolimit direct relative grounding grid current, orreduced to small current grounding low pass line to ground fault current value, in order to protectequipment set.

* current limiting reactor: current limiting reactoris mainly used to limit the short-circuit current,fault current is too high to avoid damage to theequipment, or use normal type circuit breaker,cables and other electrical equipment can use the flow reactor, without the need for more high short circuit of fixed value of the equipment, that is to say it can save cost.

* the thyristor controlled reactor: thyristor controlled reactor, TCR reactor, used in staticreactive power compensation system. The TCR reactorand the shunt reactor is similar, but the current can be composed of a thyristor control continuous.Three phase reactor is delta connected, each phasereactor is divided into two windings, the thyristoris connected in series between the two windings. TCRreactor capacity is 36KV voltage grade, 180MVA.
