Novel multi-gear tuning electric reactor

Abstract

The invention discloses a novel multi-gear tuning electric reactor, which comprises an electric reactor shell, an electric reactor body and a transmission structure, wherein the electric reactor shell covers the electric reactor body; the electric reactor body comprises an iron core and a coil; a movable structure is adopted by the iron core; the iron core is located in the middle of the electric reactor body; the electric reactor body is connected with a screw rod; the screw rod drives the iron core to move; the screw rod is located in the transmission structure; and the transmission structure further comprises a motor, a speed reducer and a chain wheel. The iron core of the electric reactor is driven to move up and down through the screw rod; an inductance value of the electric reactor can be adjusted; the output accuracy of the inductance value can be ensured; and the local discharge test requirement of the electric reactor is further met. A rectifier module is arranged between power supply equipment and a motor, so that the change amplitude of the inductance value of the electric reactor can be accurately changed; the module is powered by a booster and the pressure reducer; and the interference in local discharge caused by a silicon controlled rectifier can be avoided.

Description

technical field [0001] The invention relates to a reactor, in particular to a novel multi-block tuning reactor. Background technique [0002] In the current test system, most of the existing parallel compensation uses compensation reactors with fixed inductance. Because there is no transmission mechanism, the inductance cannot be changed. This kind of compensation can only partially compensate and cannot achieve resonance. The capacity ratio is small, the energy-saving effect is not obvious, the voltage level is fixed, and the output voltage can only be changed by a single voltage regulator, which is only suitable for a single capacitor of the specification. And a very small number of adjustable compensating reactors only rely on several compensating reactors of the same specification to adjust the total inductance through series and parallel connection, which is time-consuming and costly. Different, leading to the occurrence of heating phenomenon of individual compensation...

[0002] In the current test system, most of the existing parallel compensation uses compensation reactors with fixed inductance. Because there is no transmission mechanism, the inductance cannot be changed. This kind of compensation can only partially compensate and cannot achieve resonance. The capacity ratio is small, the energy saving effect is not obvious, the voltage level is fixed, and the output voltage can only be changed through a single voltage regulator, and only a single capacitor of the specification is applicable

And a very small number of adjustable compensating reactors only rely on several compensating reactors of the same specification to adjust the total inductance through series and parallel connection, which is time-consuming and costly. Different, leading to the occurrence of heating phenomenon of individual compensation reactors, the accuracy of the test data cannot be well guaranteed, the linear part of the inductance is difficult to ensure stability, and the energy consumption of the reactor is large, which does not meet the requirements of energy saving and emission reduction
