Problems solved by technology

[0004] Due to the large inductance value of the grounding reactor, the current grounding point reactor is wound in parallel with multiple packages of aluminum round wires, and the final product is composed of 1-8 coils connected in parallel. Due to the large number of parallel wires, The radial deviation is large, which makes the coil impedance and load loss highly dispersed. There is a no-load state in the internal winding of the coil, and the local magnetic flux leakage is too large, which will easily cause the internal overheating of the coil and cause the product performance to be unstable. The overall structure is large and occupies a large area

[0005] In addition, the existing reactors will generate a lot of heat when they are working. Generally, reactors use heat exchange to cool down. However, this cooling method has low efficiency and cannot discharge the internal heat, which is not conducive to ensuring the use of reactors. Life, based on this, now provides a high-voltage grounding reactor for offshore wind power
