Abstract
The utility model discloses a magnetic choked flow device comprising a magnetic core and a buckle-type annular body. A pluggable encircling lead is disposed in a folding port in the annular body, and the folding port of the annular body is provided with a buckling lock. The magnetic core adopts the nanometer magnetic material. The magnetic choked flow device is buckled with a power transmission line in a non-electric contact manner. No access loss is generated during the working of the power frequency. When the impact of the overvoltage occurs, a tremendous change of the magnetic flux of the nanometer magnetic material of the magnetic choked flow device can be caused by an impact current of the power transmission line, the magnetic choked flow device is suitable for the change of the lightning current strong magnetic field, and can be used for filtering and flow choking of the lightning current, therefore the effective attenuation and loss of the lightning current can be effectively generated, the action of the overvoltage like the lightning current on the leading edge gradient and the amplitude of the supporting frame can be reduced, and the influence of the impact overvoltage on the line can be reduced. The magnetic choked flow device has advantages of simple installation, convenient use, no requirement of maintenance, and abilities of reducing maintenance workload of power transmission line greatly, saving a lot of costs for later maintenance, and facilitating popularization and use.
Description
Technical field
