Description

technical field [0001] The invention belongs to the technical field of reactive power compensation equipment testing, and mainly relates to a power electronic reactor performance testing device. Background technique [0002] As an important part of the intelligent harmonic suppression reactive power compensation module, the series reactor's electrical characteristics directly affect the stable operation of the reactive power compensation equipment. According to the requirements of the standard GBT1094.6-2011 and JB54346-1998, the impedance test, temperature rise test, overload capacity test, 1.2 times rated current test with harmonics, etc. are required before the reactor leaves the factory and in the design verification stage. Whether the reactor meets the design index. [0003] When testing reactors in the prior art, most of them use a voltage regulator plus a current booster to test the rated current and reactance rate of the reactance. The most important test item is th...
