Controllable rectification separated type reactor

Abstract

The invention discloses a controllable rectification separated type reactor which is composed of a reactor consisting of four column iron cores, a main winding, controllable silicon and a control winding, wherein the main winding is immersed into an oil tank, and the controllable silicon and the control winding which is connected with the controllable silicon are arranged in a control box outside the oil tank; and the main winding is connected with the controllable silicon and the control winding in the control box through cables. With the adoption of a separated type scheme, the fault possibility of the main winding part is lower; the main winding is placed into one oil tank and necessary protection measures such as gas protection and temperature protection are carried out; the controllable silicon is easy to have faults and the maintenance convenience is considered, so that a rectifying circuit of the controllable silicon and the control winding is independently placed into one controllable silicon box, a reactor body is prevented from being opened and the maintenance amount is reduced. The reactor body is connected with the controllable silicon box through the cable simply.

Description

technical field [0001] The invention relates to a reactor, in particular to a controllable rectification separate reactor. Background technique [0002] The structure and principle of the magnetic valve controllable reactor is as follows: figure 1 shown. The reactor is composed of four-column iron core and winding. The two core columns in the middle are the working iron core, and the main winding N and the control winding N are symmetrically wound on it. K , the control winding is electrically isolated from the main winding. The control winding of each middle leg has a tap ratio of The taps are connected between them with a thyristor T 1 , T 2 ; The upper and lower main windings of different cores are cross-connected and then connected in parallel to the power supply. Since the thyristor is connected between the taps of the control winding, the voltage on it is very small, only about 0.5% of the rated voltage of the system, which ensures the reliability of operation. ...

AI Technical Summary

Problems solved by technology

[0003] At present, the magnetic valve type controllable reactor generally connects the thyristor directly in series in the circuit, puts it together with the main winding and the control winding, and puts it in an oil tank. This kind of structure is relatively simple, but the maintenance is complicated.
