Oil-immersed controllable reactor

Abstract

The invention provides an oil-immersed controllable reactor which comprises an A phase, a B phase and a C phase, and four windings are wound on an iron core column of the A phase, an iron core column of the B phase and an iron core column of the C phase respectively. A second winding, a first winding, a fourth winding and a third winding are sequentially arranged on the iron core column of each phase from inside to outside, and an iron core insulator is arranged between the second winding and the iron core column; a first insulator is arranged between the second winding and the first winding; a second insulator is arranged between the first winding and the fourth winding, and a third insulator is arranged between the fourth winding and the third winding; and the current passing through the TCT high-voltage winding is effectively reduced, so that the loss of the reactor is reduced.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to an oil-immersed 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. Although the TCR can compensate the dynamic reactive power of the power system, reduce the 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 use The air-core reactor has a large magnetic leakage, and the overall equipment occupies a large area. At the same time, the connection between the traditional reactor and the capacitor branch has a large area. SUMMARY OF THE INVENTION [0003] The purpose of the present invention i...
