Tips: 5 Precautions for installation of series reactor

1. When installing a series reactor, the wiring method of each series reactor should be connected to the bus with a separate flexible wire for students. Do not use hard bus for connection to prevent damage to the bushing of the enterprise series reactor caused by assembly stress analysis. , Oil leakage caused by damage to the seal.

2. Any poor contact in the series reactor circuit may cause high-frequency oscillating arcs, which will increase the working electric field strength of the series reactor and generate heat and cause early damage. Therefore, it is necessary to maintain good contact between the electrical circuit and the grounding part during installation.

3. When low-voltage series reactors are connected to high-voltage series power grids, insulators equal to the working voltage level should be installed to ensure reliable insulation of the shells of each reactor.

4. The series reactor is used for the higher rated voltage after the star connection. When the neutral point is not grounded, the shell of the series reactor should be insulated from the ground.

5. Before installing the series reactor, it is necessary to allocate the primary capacity to balance the phases, and the deviation should not exceed 5% of the total capacity. When equipped with a relay protection control device, it should also fully meet the requirements of balance during system operation and that the current generation error does not exceed the operating current of the relay protection technology.
