Abstract

The reactor winding, containing turns of stranded wire equipped with general insulation in the form of a silicone box of square cross section and tightening elements, characterized in that for a stranded wire with a cross section of 100 ÷ 180 mm, the side b of the silicone box lies within b = (6, l ÷ 6.3 ) d, where d is the diameter of one core.

Description

The utility model relates to the electric power industry, namely to reactors used, for example, to limit short-circuit currents in electric networks.

Known selected as a prototype reactor, containing a winding of turns of an insulated wire, bonded by means of a tightening element [RU 107639]. The insulated wire of the winding is made in the form of a multi-wire core, covered with general insulation in the form of a rectangular (in the particular case of a square) silicone box.

The disadvantage of the prototype is that with loose or too dense filling of the internal cross section of the silicone box with wires of a multi-wire core, the cross section of the windings covered by the tightening elements (ties) deviates from the square shape, providing rigidity and dynamic stability of the structure with a minimum number of ties .

Utility Model Essence

The technical result of the utility model is to increase the rigidity and dynamic stability of the design of the reactor winding without increasing the number of couplers.

The subject of a utility model is a reactor winding containing coils of a stranded wire equipped with general insulation in the form of a silicone box of square cross section and tightening elements, characterized in that for a stranded wire with a cross section of 100 ÷ 180 mm ^{2, the} side b of the silicone box is within

b = (6, l ÷ 6.3) d (one),

where d is the diameter of one core.

Utility Model Implementation

In FIG. 1 presents a stranded wire of the proposed winding, in FIG. 2 - section of a stranded wire.

The figures show: 1 - wire core, 2 - insulating coating of the core (silicone varnish or enamel), 3 - general silicone insulation of the stranded wire.

The reactor winding contains turns of stranded insulated wire and tightening elements. Each core 1 of a stranded wire may or may not have a coating 2. All core 1 of a stranded wire is covered by a common silicone insulation 3, the thickness of which is determined by the voltage class of the reactor.

General insulation 3 is made in the form of a silicone box of square cross section. The winding turns of a stranded insulated wire with insulation 3 can be tightly laid on each other and tightly covered by ties. At the same time, the design of the reactor winding is more rigid with fewer couplers. However, when tightening the turns of the winding, the outer section of the box deviates from the square shape.

In order to minimize these deviations, a technologically advanced and preferable from the point of view of stiffness is empirically determined 3

windings, the ratio of the internal dimensions of the square cross section of insulation 3 and the diameter of the core 1. This ratio for a stranded wire with a cross section of 100 ÷ 180 mm ² lies within the limits specified in expression (1).

Claims (1)

Reactor winding comprising turns of the core wire, provided with a common insulated box silicone square cross section, and tightening elements, characterized in that the cross section of the core wire 100 ÷ 180 mm ² b side of the silicone conduit lies within b = (6, l ÷ 6.3) d, where d is the diameter of one core.
