Problems solved by technology

Although TCR can provide dynamic reactive power compensation for power systems, reduce voltage fluctuations, stabilize system voltage levels, and solve problems such as charging power and reactive power transfer; however, the two ends of the TCR thyristor valve group directly bear the system voltage, and the air-core reactor used The magnetism is large, and the overall equipment occupies a large area; and the traditional reactor and capacitor branch circuit occupy a large area

Abstract

The invention provides a three-phase core type controllable reactor which comprises a phase A, a phase B and a phase C. Two windings are wound on an iron core column of each phase. The two windings are respectively a first winding and a second winding, and the head and tail ends of the first winding of each phase are sequentially connected to form triangular connection; the tail ends of the second windings are connected and led out to form star connection with a center line; and the problem of large occupied area of the whole equipment is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to a three-phase core type controllable reactor. Background technique [0002] SVC includes Thyristor Controlled Reactor, TCR for short, Megnetic Controlled Reactor, MCR for short, etc. Among them, each phase of TCR adopts a pair of anti-parallel thyristor valves and a linear hollow reactor. Composed in series. Although TCR can compensate the dynamic reactive power of the power system, reduce voltage fluctuation, stabilize the system voltage level, and solve the problems of charging power and reactive power reversal; but the two ends of the TCR thyristor valve group directly bear the system voltage, and the air-core reactor used leaks The magnetic field is large, and the overall area of ​​the equipment is large; and the traditional reactor and capacitor branch circuit covers a large area. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is ...
