Embodiment Construction

[0024] The embodiment of iron core type split reactor in the present invention is such as Figure 1-5 shown. The iron-core split reactor includes a bracket and three reactor units arranged on the bracket in a "one" shape along the left and right directions, with phase A, phase B and phase C being equal. Each reactor unit includes two coaxial split coils extending along the up and down direction, the split coil located on the outside is the outer split coil 3, the split coil located on the inside is the inner split coil 2, and the inside of the inner split coil 2 is provided with Iron core 1 coaxial with the split coil. Each of the split coils includes an incoming wire end for being connected to the same main circuit and an outgoing wire end for connecting to the corresponding branch circuits respectively. There are two outgoing wire rows connected, and the two outgoing wire rows are symmetrically arranged on the front and rear sides of the bracket through the upper insulator...

Abstract

The present invention relates to an iron core-type split reactor. The iron core-type split reactor comprises a rack; the rack is provided with at least one reactor unit; the reactor unit comprises at least two coaxially arranged split coils with axes extending vertically; each split coil comprises a wire inlet end used for and provided in a same main circuit and a wire outlet end used for connecting to a corresponding branch circuit respectively; and an inner side of an innermost split coil is provided with an iron core being coaxial with the split coil. The wire inlet ends of the split coils are disposed in the same main circuit, the outlet ends are connected to the corresponding branch circuits respectively to limit a short circuit current, and the inner side of the innermost coil is provided with the iron core, so that the iron core-type split reactor is low in loss, small in flux leakage and small in volume.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to an iron-core split reactor. Background technique [0002] The reactor is essentially an inductive element. The reactor essentially provides the inductance value on the electrical circuit. The function of the current-limiting reactor is to limit the short-circuit current. Reactors are connected in series in the electrical circuit. When a short circuit occurs, the existence of the reactor increases the short-circuit impedance and limits the short-circuit current. At the same time, the voltage drop on the reactor is large, so the reactor also plays a role in maintaining the voltage level of the electrical circuit. The function makes the voltage fluctuation of the electrical circuit smaller, and ensures the stability of the operation of the electrical equipment on the non-fault line. In order to satisfy the electrical circuit with branch lines, split reactors are usu...
