Problems solved by technology

Therefore, when making an air-core reactor, a large insulation distance is required between the two sets of coils, but when the insulation distance is increased, the coupling coefficient of the two sets of coils will be reduced, so the technical problem of the dilemma has not been resolved.

Abstract

The invention belongs to the technical field of air core split reactors, and particularly provides a high-coupling air-core split reactor. The transformer comprises a cylindrical first winding and a second winding with the outer diameter smaller than the inner diameter of the first winding. Wherein the first winding and the second winding are concentrically sleeved, a cylindrical insulating barrier is arranged between the first winding and the second winding, the lower end of the cylindrical insulating barrier is longer than the first winding and the second winding, the upper ends of the firstwinding and the second winding are common wire inlet ends, and the lower ends of the first winding and the second winding are split wire outlet ends. Through the arrangement of the cylindrical insulation barrier, the contradiction between the insulation and the coupling coefficient of the air core split reactor is solved.

Description

technical field [0001] The invention belongs to the technical field of air-core split reactors, and specifically provides a high-coupling air-core split reactor. Background technique [0002] High-coupling air-core split reactors can be used to limit short-circuit current, the principle is as follows figure 1 , when the line is running normally, K is closed, at this time L1 and L2 are connected in antiparallel, the magnetic field cancels, and the overall inductance is small; when the circuit is short-circuited, K is broken, and only L1 is running. At this time, the inductance is the inductance value of L1, which limits the short circuit Current, although the absence of current in L2 will not cancel the magnetic field, but the mutual inductance voltage of L2 still exists. There will be a terminal voltage equivalent to the line voltage at the outlet of the X terminal of the inductor L1 and L2. Considering the operating overvoltage of the inductor, the voltage here will be hig...
