Abstract
This utility model is a needle and post composite insulator without being binded, provided with an upper accessory, an insulating mandrel, an umbrella sleeve and a lower accessory, the upper accessory is provided with a pressing line clamp used for fixing high voltage connecting wires, both the upper and lower accessories are provided with seal grooves, the insulating mandrel sleeved fixedly between the upper and lower accessories is a synthetic fiber reinforced plastics rod, the unbrella sleeve covering the upper and lower accessories and the insulating mandrel is a tower-shaped umbrella sleeve made of silicon rubber materials, the lower accessory is provided with screws or bolts, and the umbrella sleeve is complete sulfide press molded. This utility model solving the problems of current porcelain and glass insulators such as being easy to be penatrated, easy to be broken, heavy and inconvinient to be installed, which simplifies the installing process, improves the safety, reliability and antipollution capacity of high voltage transmission, lengthens the service life of products and is suitable for the needle and post composite insulators from 10 to 35 KV.
Description
Technical field the utility model is the bindless needle type line pole type composite insulator that uses on a kind of ultra-high-tension power transmission line.
Background technology is existing produces traditional pin type, the line post insulator of using, and no matter its material is porcelain, glass or organic material, and the mode of their fixing cords all is with little lead the high-voltage line colligation to be fixed; Existing pin type, the line pole type metalwork of producing is connected with plug to be needed to fix with lateral pin, easily loosening; The artificial hand that is sealed into of metalwork and plug junction seals, and the plug moisture-sensitive is easy to make plug and rubber interface because of the punch through damage of making moist.
The goal of the invention the purpose of this utility model be propose a kind of make high-voltage conducting wires easy for installation, safe and reliable, can not puncture design, antifouling property good, light, do not allow bindless needle type line pole type composite insulator frangible and fracture, with the solution the deficiencies in the prior art.
This bindless needle type line pole type composite insulator that summary of the invention the utility model proposes, it has last annex, insulation mandrel, umbrella body cover and following annex, it is characterized in that having on the annex the fixedly line ball folder of high-voltage conducting wires.
The arc groove and the screw that are fit to hold high-voltage conducting wires arranged on the last annex top, constitute the line ball folder with tension disc and line ball bolt.
Upper and lower annex all has seal groove, and the insulation mandrel that closely is socketed on therebetween is the polymethyl methacrylate steel core bar.
The umbrella body of sealing upper and lower annex and insulation mandrel is the tower shape umbrella sleeve that a silastic material is made.
Have on the following annex screw thread, bolt and/or nut, packing ring are installed.
The upper and lower annex of metallicity is connected with the mechanical roll-in of being connected to of insulation mandrel.
The silicon rubber umbrella body cover that is enclosed within on insulation mandrel and the upper and lower annex is whole sulfuration compression molding body.
Invention effect the utility model adopts the line ball clamping to decide the mode of tight socket insulation mandrel between high-voltage conducting wires and metalwork, it is big and the problem of inconvenience is installed to have solved the easily puncture of existing porcelain and glass insulator, easy fracture, weight, simplify installation procedure, improved the fail safe and the reliability of high voltage power transmission; The umbrella body interplanting external insulation of silastic material has strengthened antipollution performance again, makes its breakdown characteristics stronger, longer service life, and the pin type and the line pole type that are suitable for 10-35KV are answered insulator.
In addition, the utility model has attractive appearance generous, and the mechanical strength height almost is to puncture freedom from repairs.
Appended drawings 1 is front view of the present utility model (broken section).
Accompanying drawing 2 is that the installation screw thread is the insulator front view (broken section) of outside screw type.
Accompanying drawing 3 is the vertical views with respect to Fig. 1 and Fig. 2.
As Figure 1-3, the label of each parts is as follows:
The 1-tension disc; 2-line ball bolt; The last annex of 3-; 4-umbrella body cover; The 5-insulation mandrel; Annex under the 6-; 7-installs screw thread.
Embodiment
Example one
As shown in figs. 1 and 3.This form is applicable to that the 33KV circuit uses, and is column support type.Line ball presss from both sides as mentioned above, and the aperture that tension disc and groove constitute is 25MM, last annex column diameter 32MM, insulation mandrel diameter 24MM, long 318MM, the umbrella body portion diameter 106MM of umbrella body cover, umbrella spacing 40MM.Open internal thread on the following annex termination and make to install screw thread, size is identical with existing installation code.
Example two
Shown in Fig. 2 and 3.This form is applicable to that the 11KV transmission line uses, and is pin type and line pole type, and line pole type steel pin can be joined Great Britain and America Australia standard pin.The aperture that tension disc and groove constitute is 20MM, last annex column diameter 24MM, and insulation mandrel diameter 18MM, long 100MM, the umbrella body of umbrella body cover is established three, and two big one is little, and diameter is respectively 100MM and 70MM.Following annex installation external screw thread to the distance of the clamp hole heart is 190MM, and screw thread head length 38MM is installed, and all the other situations as shown in the figure.
Through on probation, more than easy for installation, the weight of two kinds of insulators alleviated 20% than the porcelain like product, waterproof and dampproof and pollution-proof performance is superior, loosening and bending phenomenon are not seen in long-term use, do not need repairing, and do not see punch through damage yet, it is safe and reliable to transmit electricity.This product jolts even fierceness occurs in transportation, also neither one fracture or broken.The trier is very satisfied.
