Product Desciption

Product Profile:

Shunt reactor is mainly connected with shunt capacitor in parallel, which can adjust the operation voltage by adjusting the number of shunt reactors.The low voltage shunt reactor has many functions to improve the reactive power of the power system:(1) the capacitive effect on the light load or light load lines to reduce the power frequency transient overvoltage.(2) improve the voltage distribution of long distance transmission line.(3) the reactive power of the line in the light load can be balanced on the spot as possible as possible to prevent the unreasonable flow of reactive power and also to reduce the power loss on the line.(4) reduce the power frequency steady voltage on the high voltage bus when the large unit and the system are juxtaposed, so that the generator can be juxtaposed at the same time.(5) prevent the self excitation resonance generator with long lines possible.(6) when the reactor neutral point is earthed by small reactance, the small reactor can compensate the phase and ground capacitance of the line, so as to speed up the automatic extinction of the secondary supply current and facilitate the adoption of the capacitor.

Technical characteristics:

Our company designs and produces independently, the silicon steel sheet adopts cold rolled oriented silicon steel sheet, the coil is made of foil winding or lead, carrying capacity, good linearity in harmonic environment (flow 1.3 times) reactor is always running in the linear range, reactor parameters remain stable, impregnating medium is F class insulation epoxy resin, viscosity is strong, operation temperature rise is small, the noise is low.With the advanced dipping winding technology, the whole reactor is formed into a compact and solid whole after high temperature curing, so as to improve the overall mechanical strength of the reactor.The noise is low and the noise is less than 65db;The reactor has the advantages of simple structure, small size, no maintenance and convenient installation in the cabinet.The inductance is accurate, the linearity is good, and the temperature rise keeps reasonable allowance.
