Embodiment Construction

[0021] As shown in the figure, the dry-type air-core reactor with an interchangeable assembled structure includes a plurality of windings 3 (in this embodiment, three windings) using copper wires (or aluminum wires), a cast stainless steel transition clip 1, The transition clamp fixture 1 is divided into an exposed part and a pre-embedded part, the exposed part of the transition clamp clamp is provided with two clamp installation holes 101 laterally, and the embedded part of the transition clamp clamp is provided with wire connection holes from outside to inside 102 and a transverse circular groove 103. In this embodiment, the wire connection holes 102 are arranged in three rows and arranged up and down, and each row has two wire connection holes. Each wire 5 in the winding 3 passes through the wire connection hole 102 of the transition clamp 1 (passes through one wire connection hole in the same row, passes through another wire connection hole in the same row). The glass fibe...

Abstract

The utility model discloses a dry-type air-core reactor with an interchangeable splicing structure. The reactor comprises a plurality of windings and a transition clamping piece clamp, and the transition clamping piece clamp is divided into an exposed part and a pre-embedded part from top to bottom. The wire of each winding is connected with the pre-embedded part of the transition clamping piece clamp; the windings transversely wind the glass fiber wounded by and soaked in epoxy resin so as to form an independent winding package; the pre-embedded part of the transition clamping piece clamp isfixedly pre-embedded in the winding packaged; an upper star-shaped support and a lower star-shaped support are arranged on the upper surface and the lower surface of the winding package respectively;the exposed part of the transition clamping piece clamp is fixedly connected with the upper star-shaped support and the lower star-shaped support; and incoming and outgoing lines of the dry-type air-core reactor are led out through the star-shaped supports. Each package is independently wound, so that the circumference of the electromagnetic wire is more accurate, and the inductance precision of the reactor can be improved; the paint on the surface of each package can be completely covered, so that the problem that the paint between the surfaces of the package of the traditional structure is not completely covered is solved; and when a single package fails, targeted disassembly and interchange can be performed, so that raw materials is savled and labor cost is reduced.

Description

technical field [0001] The invention relates to a reactor, in particular to a dry-type air-core reactor with an interchangeable assembled structure. Background technique [0002] Dry-type air-core reactors have been widely used in reactive power compensation and filter power systems. With the rapid development of the global power system, the design capacity requirements of dry-type air-core reactors are also increasing. Large-capacity dry-type air-core reactors are often Multiple envelopes and multi-layer windings are required to meet the design temperature rise requirements of dry-type air-core reactors. When a single package in the middle needs to be replaced or damaged, the entire reactor needs to be repaired as a whole, which is inconvenient to process and wastes material and labor costs. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and to provide an interchangeabl...
