    dry-type semi-core reactor


    I.Introductionto dry-type semi-core reactor
    Dry-typesemi-core reactor is the original patent product of Xi’an Zhongyang ElectricCo., Ltd. in the worldwide and integrates the structure characteristics ofdry-type air-core reactor and dry-type iron-core reactor. The new idea that theiron core can be placed into the air core of the dry-type air-core reactor tomake the reactor is realized for the first time, and the great breakthrough isachieved in the whole structure of the reactor, and the technology is in the internationaladvanced level. The product has remarkable energy conservation effect and thecharacteristics of low noise, high mechanical strength, good linearity, strongresistance to short-circuit impact, and pollution-free, conforms to theelectrical products’ development trend of “oil-free, minimization, energyconservation and environmental protection” and has outstanding economic valueand extensive social benefit. The original energy conservation informationcenter of State Economic and Trade Commission selects it the best energyconservation case for nationwide popularization.
    II. Characteristics ofdry-type semi-core reactor
    1.The electric energy loss reduces 25 to 40% under the same specification andcapacity;
    2.Diameter shrinks 20 to 30% under the same specification and capacity;
    3.Floor area is saved 20 to 45% under the same specification and capacity;
    4.Volt-ampere characteristic is still linear within the scope of twice ratedoperating voltage;
    5.Lowoperating noise;
    6.Able to long-time operate in outdoor environment;
    7.It has other virtues of the dry-type air-core reactor;
    8.It has excellent cost performance.
    III. Classification andfunction of dry-type semi-core reactor product


    1.Dry-typesemi-core series reactor

    It is the reactor serially connected with the shunt reactor in theelectrical power system to inhibit the wave distortion of power grid voltage,control the harmonic component flow-through capacitor and limit the combinationlock surge of capacitor. (DL462-92)

    2.Dry-typesemi-core shunt reactor
    It is thereactor connected between the phase and ground, phase and neutral points orphases to compensate the capacitive current. (GB1094.6)
    Dry-typeSemi-core Shunt Reactor
    3.Magnetically-shieldedreactor
    Themagnetically-shielded reactor is formed by adding an annular magnetic shieldingencapsulation on its coil exterior on the basis of dry-type semi-core reactor,so, it not only has low loss, small size, and able to operate in outdoor etcadvantages, and has the unique magnetic field shedding characteristic, whichmakes the leakage magnetic field surrounding the coil and magnetic pollutionlargely reduce under the same capacity; it is able to satisfy the indoor andoutdoor places with high installation space requirements; its cost performanceis better than iron-core reactor and air-core reactor.
