Example Embodiment

[0025] The present invention will be further described below with reference to the drawings and embodiments.

[0026] The structure and connection of a saturable reactor with a simple structure are as follows figure 1 Shown. Including saturated reactor terminal I 1, saturated reactor terminal II2, saturated reactor closed loop iron core 3, control circuit 4. The saturable reactor closed-loop iron core 3 has at least two iron core legs with the same cross-sectional area and coils; each of the two iron core legs can form at least one magnetic flux closed loop that does not pass through the other core legs. One of the iron core legs has a coil L1 and the other has a coil L2; the number of turns of the coil L1 and the coil L2 is equal.

[0027] The closed-loop iron core 3 may be two closed-loop iron cores with no mutual passage, for example, 1: two square-shaped iron cores. It can also be a one-piece closed-loop iron core with mutual paths; for example 2: three iron core legs, the t...

Abstract

The invention relates to a saturation resistor with a simple structure. The saturation resistor with the simple structure comprises a closed loop iron core, wherein coils are respectively arranged on two iron core limbs of the closed loop iron core; the turns per coil are the same; dotted terminals of the coils in the two iron core limbs are connected with a terminal I, and resistances are respectively connected between opposite terminals of the coils in the two iron core limbs and a terminal II; the resistance values of the resistances are the same; one resistance R1 is connected with a positive thyristor D1 in parallel, and the other resistance R2 is connected with a reverse thyristor D2 in parallel; the control end of each thyristor is connected with a control circuit; the control circuit controls the size of a trigger angle of each thyristor, so that the size of the reactive value of the saturation resistor can be continuously adjusted.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation in power systems, in particular to a saturated reactor with a simple structure. Background technique [0002] Reactors are widely used in power systems. The series reactor can limit the short-circuit current; the shunt reactor can limit the overvoltage; the combination of the reactor and the capacitor can form a filter circuit. In some application fields, the reactance value of the reactor is fixed; in some application fields, the reactance value of the reactor should be adjusted continuously with the change of the power system operation mode. The controllable saturable reactor (also called: saturable reactor, magnetron reactor) whose reactance value can be adjusted continuously is an important research topic. [0003] The saturable reactor uses the saturation characteristics of the closed-loop iron core of the saturable reactor to change the reactance value of the ...
