Knowledge sharing of series resonant reactors

Series resonant reactor

The reactor is designed with a hollow structure, enameled copper wire winding, oil immersed self cooling type, and adopts a fiberglass insulated cylinder shell, which has sufficient electrical and mechanical strength, necessary heat dissipation capacity, and margin for oil thermal expansion and contraction. The reactor is equipped with reliable lifting specialized facilities. The shell is sprayed with red insulation paint and uses 25 # transformer oil.There is no deformation or leakage during work.The independent insulation chassis shell has non-magnetic insulation materials for the upper and lower cover plates and flanges. The middle voltage equalization ring considers the voltage equalization when 2 high-voltage reactors are stacked, and the top voltage equalization ring considers the voltage equalization when 5 high-voltage reactors are stacked.Aluminum alloy material is used, and measures are taken to prevent the equalization ring from heating up when short-circuit circulating current occurs under strong magnetic fields; The size of the voltage equalizing ring shall ensure that it does not produce corona under rated voltage; The equalizing ring is easy to disassemble and assemble, the metal bracket of the reactor base has sufficient stability, can adjust the level, is easy to disassemble and assemble, has a lifting device, and measures are taken to prevent eddy current heating under strong magnetic fields

The internal structure of the reactor remains in the same position after normal railway and road transportation, and the fasteners are not loose. The reactor has a nameplate that complies with national standards. The nameplate is made of corrosion-resistant materials, with clear and durable words and symbols. The installation position of the nameplate is clearly visible during normal equipment operation, and the nameplate contains data such as rated voltage, inductance, operating frequency, weight, etc.

1. High voltage end: connected to the test end of the test sample and the high voltage end of the voltage divider

2. Low voltage end: connected to the output high voltage end of the excitation transformer

When the test voltage is higher than the rated working voltage of the reactor, multiple reactors should be used in series, and the bottom of the reactor at high potential should be equipped with a special insulation base!

When the test current is greater than the rated working current of the reactor, multiple reactors should be used in parallel. Unless otherwise permitted, reactors of different specifications should not be connected in series or parallel.
