Abstract
Dry-type air-core reactor component loosing-proof device, including upper starframe (1), lower starframe (2), coil (3), upper and lower starframe and coil (3) are attached by pull rod (4) and dry-type air-core reactor reinforced to prevent the upper and lower starframe of air reactor to be loosened with coil three parts, makes this three parts into being integral；The utility model loosens reason, harm and processing, product structure or production technology defect for dry air core reactor star frame, airway strip, and at runtime, vibration and coil temperature expand with heat and contract with cold when changing to be caused product.This project solves the problems, such as that reactor airway strip loosens using new material research, the function that should have when making dry-type air-core reactor that should meet operation requirement after safeguarding, and reaching manufacture.
Description
Technical field
The utility model category power industry scene runs dry-type air-core reactor locking device, can thoroughly prevent airway strip
It comes off, avoids the reactor accident caused by airway strip comes off, improve reactor reliability of operation, reduce the maintenance of reactor
Number improves the service life of reactor.
Background technology
Transformer substation reactor airway strip loosens and comes off resets and fixes the influence and harm to reactor not in time, with
Reactor is vibrated by the electrodynamic impact of switching and operation, and the airway strip of reactor is gradually loosened and come off.It may cause：Electricity
Anti- device operation noise becomes larger；Reactor airway strip comes off excessively, and the supporting point between encapsulating is reduced, and relative position becomes between causing encapsulating
Change and the close sharp increase of indivedual branches electricity occur in lead head rupture, destruction Reactor Branch balance, local temperature rise is higher, causes insulation
There is turn-to-turn short circuit after aging and burn；The inductance of reactor changes, and changes reactance Rate, leads to reactor capacity and electric current
Change, very big hidden danger is brought to the safe operation of reactor.Cause to loosen between encapsulating and starframe, each weld bond of starframe is split
It opens, aggravates coming off for airway strip, rubbing between starframe and coil leads to insulation harm, ultimately causes reactor and burns；Such as closed assembly
Reactor product may result in product and collapse.When airway strip comes off, if one end is leaned against on aluminium row, the other end leans against another phase aluminium
It (closed assembly product) or is fallen on the ground on row, rainwater can lead to phase fault or short over the ground along airway strip toward flowing down when raining
Road.
Invention content
A kind of intend using new construction is provided the purpose of the utility model is to overcome the problems of the above-mentioned prior art
To starframe loosening processing, the device so as to prevent airway strip from loosening.
The utility model is realized by following technological means：
The anti-hidden danger device of dry-type air-core reactor superstructure loosening, including upper starframe, lower starframe, coil, upper and lower star
Frame and coil are attached by pull rod and dry-type air-core reactor are reinforced to prevent the upper and lower star of air reactor
Frame and coil three parts loosen, and make this three parts into being integral；Wherein, upper starframe structure is：Center is set there are one aluminium axis
Set is uniformly distributed in the slot on the outside of aluminum sleeve and is fixedly connected with six pieces of aluminium rows, and aluminium row is in vertical structure, and one of aluminium row is slightly
It is long, offer connecting hole in the slightly long section；Lower starframe structure also arranges bottom in addition to identical with upper starframe structure in every block of aluminium
Bottom plate is respectively fixedly connected with, every piece of bottom plate is located at aluminium row both sides and offers mounting hole；
The structure of pull rod is：Including a single u-shaped insulating bar, it is tight that a U-shaped stainless steel is cased in the ring on U-shaped insulating bar top
Firmware distinguishes tapped section in two openends of U-shaped stainless steel support, and a fluting and with holes is cased on the thread segment
Cross-over block, be threadedly coupled on cross-over block with thread segment using nut.
The beneficial effects of the utility model are that processing starframe loosens, and thoroughly prevents coming off for airway strip, avoids because of air flue
Reactor accident caused by item comes off, improves reactor reliability of operation, reduces the maintenance number of reactor, improves reactor
Service life.
Description of the drawings
Fig. 1 is the utility model dimensional structure diagram；
Fig. 2 is drawbar structure diagram front view；
Fig. 3 is drawbar structure diagram left view.
Specific embodiment
Utility model is described further below in conjunction with the accompanying drawings.
See Fig. 1-Fig. 3, the anti-hidden danger device of dry-type air-core reactor superstructure loosening, the utility model it is characterised in that it includes
Upper starframe 1, lower starframe 2, coil 3, upper and lower starframe and coil 3 are attached by pull rod 4 and to dry-type hollow reactance
Device is reinforced to prevent the upper and lower starframe of air reactor and is loosened with coil three parts, makes this three parts into being integral；
Wherein, upper 1 structure of starframe is：Center is set there are one aluminum sleeve 7, is uniformly distributed and is fixedly connected in the slot on the outside of aluminum sleeve
Six pieces of aluminium rows 8, for aluminium row in vertical structure, one of aluminium row is slightly long, and connecting hole 9 is offered in the slightly long section；Lower 2 knot of starframe
Structure also arranges 8 bottoms in every block of aluminium and has been respectively fixedly connected with bottom plate 10, every piece of bottom plate 10 in addition to identical with upper 1 structure of starframe
8 both sides, which are arranged, in aluminium offers mounting hole；
The structure of pull rod 4 is：Including a single u-shaped insulating bar 4.1, it is U-shaped in the ring on U-shaped 4.1 top of insulating bar to be cased with one
Stainless steel support 4.2 distinguishes tapped section 4.3, in the thread segment in two openends of U-shaped stainless steel support 4.2
On be cased with a fluting and cross-over block 4.4 with holes, using nut 4.5 on cross-over block 4.4 with 4.3 screw thread of thread segment connect
It connects.
The utility model carries out corresponding insulating bar and U-shaped stainless steel support, so according to dry-type air-core reactor size
Scene takes insulating bar to catch lower starframe bottom end and is transmitted to starframe lower end, then pass through U-shaped stainless steel in coil inner cylinder afterwards
Fastener entangles insulating bar and is transmitted to starframe upper end, finally puts on cross-over block and tightens fixation by nut.
