Abstract

The invention discloses a multi-shift dry-type air reactor which comprises a reactance winding, a plurality of wiring bars and a rotation mechanism, wherein each wiring bar is vertically arranged on an inner arc wall of the reactance winding in a symmetrical way, the rotation mechanism comprises a driving shaft, the driving shaft is vertically arranged and is movably arranged at the central position of the interior of the reactor in a spiral rotation lifting way, the upper end of the driving shaft is provided with a steering arm extending along a horizontal direction, a copper column is arranged at the axis central position of the driving shaft and the steering arm, a first contact end is led from the outer side surface of the steering arm, a second contact end is led from the bottom of the driving shaft and is connected with the output end of the reactor, the motion path of the first contact end is consistent to the spiral line of the reactance winding, and the first contact end is selectively and electrically connected with one of openings. By the multi-shaft dry-type air reactor, the problems of inconvenience in shift regulation of the reactor, high cost, large occupied area and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electrical equipment, in particular to a multi-shift dry-type air-core reactor. Background technique [0002] In the field of high-voltage power transmission and distribution technology, reactors play a pivotal role. They can be used as reactive power compensation devices for lines, voltage buffer devices, voltage dividing reactors, and other purposes. In practical applications, it is often necessary to adjust the inductance value of the reactor to meet the system requirements. In the prior art, several taps are often arranged at different positions of the reactor, and each tap is connected to the tap changer. For different gear connections, adjust the value of the reactor by adjusting the gear access position of the tap changer. [0003] The disadvantage of the existing technology is that each adjustable reactor needs to be equipped with a separate tap changer, and a large number of connect...
