Abstract

The invention discloses a super-conducting type controlled reactor with high leakage reactance. Three windings are wound on an iron core (1), a primary copper main coil (2), a secondary super-conducting control winding b (4) and a secondary super-conducting control winding a (3) are sequentially arranged from outside to inside, and the primary copper main coil (2), the secondary super-conducting control winding a (3) and the secondary super-conducting control winding b (4) are independent of one another. The super-conducting type controlled reactor with the high leakage reactance has the advantages of low induced voltage, low winding consumed power and high linearity, a function of limiting secondary arc current can be realized, and the quantity of super-conducting windings in practical application can be configured according to volume regulation of the controlled reactor.

Description

technical field [0001] The invention belongs to a superconducting controllable reactor device in the application field of superconducting technology, in particular to a controllable high-temperature superconducting winding to improve the effective control of the short circuit and open circuit of the secondary superconducting control winding, which can be controlled by the main magnetic flux The control of the cross-sectional area of ​​the loop realizes the adjustment of the reactance value. Background technique [0002] Traditional reactive power compensation devices include synchronous condenser (SC), shunt capacitor, static var generator (SVG) and shunt reactor. Synchronous condenser is a rotating motor, because of its large loss and noise, complicated operation and maintenance, and slow response speed, it is rarely used at present. Shunt capacitors are generally used in power systems together with reactors or resistors as reactive power compensation and filtering devices...
