Background
The existing dry-type air reactor has the advantages of uniform initial voltage distribution, good linearity, low loss, low noise, convenient installation, simple maintenance and the like, and is widely applied to a power system. However, the dry-type air reactor has no closed magnetic loop, so that the dry-type air reactor generates a large magnetic field around the dry-type air reactor, the magnetic leakage is very serious, and the dry-type air reactor has strong penetrating power, thereby not only influencing other surrounding electrical equipment, but also forming potential harm to occupational exposure.
Aiming at the problem of magnetic leakage of the dry hollow reactor, the influence of a power frequency magnetic field on the health of a patrol worker is reduced only by increasing the distance between the patrol worker and the reactor in the conventional power department, but because the distance between the conventional dry hollow reactor and a patrol channel is limited by the floor area of a transformer substation and is often short, the ground power frequency magnetic field of the patrol channel is often larger than the national contact limit standard (namely 100 mu T).
In conclusion, the technical problem to be solved urgently by technical personnel in the field is that the power frequency magnetic field generated by the existing dry-type air-core reactor is large and cannot meet the contact limit standard.
