Abstract
The utility model relates to an adjustable suspension device for shock absorption ring. The technical program is that comprising a suspension support, a fixed contact support, a support cover, a shock absorption ring, an U-shaped bolt and a corona nut, wherein the suspension support and the fixed contact support are respectively attached on the upper and lower parts of the shock absorption ring which are arranged in the suspension support and the fixed contact support, the support caps are respectively added on the lower end of the suspension support and the upper end of the fixed contact support, the U-shaped bolt and the corona preventive nut are used to respectively tighten the suspension support and the fixed contact support with the corresponding support cap and the opening of the U-shaped bolt is arranged inward of the shock absorption ring. The utility model has the advantages that: the end of connection rod on the shock absorption ring is adjusted into the shock absorption ring to ensure that the electric intensity is distributed evenly and protected under shielding of the shock absorption ring, the balling corona bolt is srewed to the exposed screw to effectively eliminate corona and radio interference frequently occurred in the power station, and the resolution plan is simple and feasible, thereby considerably improving performance-to-price ratio of the product.
Description
Technical field
The utility model relates to built on stilts power transmission and distribution power station gold utensil, more particularly, relates to a kind of adjustable weakening ring suspension apparatus.
Background technology
Weakening ring suspension apparatus is the special-purpose gold utensils of a kind of built on stilts power transmission and transformation, is extensive use of in transformer station, and its effect is being connected and utilizing the strain of weakening ring to weaken the stressed and vibration of lead of isolating switch contact head in fixing and the suspention transformer station.Adjustable weakening ring of the prior art adopts overhung construction usually, and the wire clamp that supports gold utensil all is the lead fixed that will play weakening and current-carrying effect by the U bolt.According to the electric armour clamp installation requirement, the screw rod of connecting screw should exceed clamp nut end face 2～3 teeth.The weakening ring all adopts and goes up anti-formula structure at present, and the wedge angle of screw rod the raised area all is exposed to the outer end of weakening ring.Under the application conditions of superhigh pressure, because the electric potential gradient of product surface has surpassed critical value, produce ionization and send the radiance of blue look, it is the corona discharge phenomenon, both consumes energy, also can produce radio interference to environment, be the problem that should avoid in the power construction, but this problem is solved always well.
Summary of the invention
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, a kind of adjustable weakening ring suspension apparatus that design can prevent to occur corona phenomenon too early and be particularly suitable for using under the superhigh pressure state, and it is realized by following technical scheme:
Comprise pipe-hanging hook, stationary contact bracket, bracket cover, weakening ring, U-bolt, wherein in also comprising anti-corona nut, described pipe-hanging hook, the stationary contact bracket up and down both sides of weakening ring that are placed in, weakening ring both end sides up and down places respectively in pipe-hanging hook and the stationary contact bracket, add a cover bracket cover respectively in the lower end of pipe-hanging hook and the upper end of stationary contact bracket, respectively that pipe-hanging hook, stationary contact bracket is fastening with corresponding bracket cover with U-bolt and anti-corona nut, and make the U-bolt openend in the ring of weakening ring.
Described anti-corona nut is the anti-corona nut of ball-type, spins to be included in U-bolt openend two screw rods end, guarantees not have thread to expose.
The outside of described pipe-hanging hook and stationary contact bracket is connected with shading ring respectively.
The beneficial effects of the utility model are: all openends that are connected the U-bolt on the weakening ring are all adjusted in the weakening ring, make pipe-hanging hook and stationary contact headstock all place the weakening ring outside, so both made electric-field intensity distribution even, the generation that has utilized the shielding action of weakening ring to solve corona phenomenon effectively again; While spins for the bolt end that is exposed to the nut outer end in the anticorona nut of ball-type, the thread wedge angle part of bolt end all is included in the anticorona nut of this ball-type, avoid the wedge angle electric discharge phenomena of product, preferably resolved the superhigh pressure (problem of the corona in power station and radio interference particularly＞220KV).Above-mentioned structure regulates and improves simple, the safety and reliability of its product is improved significantly, thereby cost performance of product is improved greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1
Among the figure, the 1st, pipe-hanging hook, the 2nd, shading ring, the 3rd, weakening ring, the 4th, stationary contact bracket, the 5th, U-bolt, the 6th, bracket cover, the 7th, the anti-corona nut of ball-type, the 8th, lead, the 9th, fixed contact, the 11st, bolt.
Embodiment
Below in conjunction with drawings and Examples the utility model and advantage thereof are described further.
Please contrast Fig. 1, Fig. 2, pipe-hanging hook 1, stationary contact bracket 4 place weakening ring both sides up and down respectively, and they are all formed by the aluminium alloy casting.Weakening ring 3 usefulness rope-lay strands are made circular, and both end sides places respectively in pipe-hanging hook 1 and the stationary contact bracket 4 about it, and adds a cover bracket cover 6 respectively in the lower end of pipe-hanging hook 1 and the upper end of stationary contact bracket 4.The two screw rods of U-bolt openend is by direction in the ring exocyclic of weakening ring 35 respective aperture on cross-under pipe-hanging hooks 1, stationary contact bracket 4 and the corresponding bracket cover 6 respectively, use the anti-corona nut of ball-type 7 fastening again, make the U-bolt openend like this in the ring of weakening ring.The two screw rods end of U-bolt 5 openends is held by the pommel bread of the anti-corona nut 7 of ball-type.
The utility model is when mounted: the upper end of the pipe-hanging hook 1 of its upside connects lead 8, and the lower end of the stationary contact bracket 4 of its downside connects fixed contact 9.When the voltage on the lead 8 is connected a shading ring 2 with bolt 11 respectively in the outside of pipe-hanging hook 1 and stationary contact bracket 4 during greater than 220KV, with the electric field that evenly around weakening ring 3, produces by lead 8.
During work, because all connectors on the weakening ring are all adjusted in the weakening ring, make electric-field intensity distribution even, simultaneously, the effect of weakening ring current-carrying produces electric screen to its upper connector, can effectively solve the normal corona phenomenon that occurs of existing product.In addition, its exposed portions serve of two screw rods that is connected on the U-bolt 5 on the weakening ring is all contained by the anti-corona nut 7 of ball-type, and all thread wedge angle parts all are included in the nut of rounding off, have avoided the wedge angle electric discharge phenomena of product.The good electrical characteristics of the anticorona grade of the utility model product are confirmed in the correlation test of being done by State Grid Corporation of China's Wuhan High Voltage Research Institute on April 29th, 2006.Therefore, the utility model product is fine to have solved corona and the radio interference problem that existing power station occurs often, and solution is simple, thereby it adds than improving greatly the property of product.
