Abstract
The utility model relates to a column synthetic insulation metal oxide arrester which is composed of a metallic oxide core, electrodes, an insulating sleeve, and a metallic sealed cap, and the utility model can be used for power circuits. The utility model is characterized in that the high-strength insulating sleeve 3 and a rubber buffer layer 2 are inlaid outside the metallic oxide core 1, both ends of the outermost layer insulating sleeve 7 and the core 1 are provided with convex cylinder electrodes 6, end surfaces of electrodes are provided with pile head double nut holes 9, the metallic seal cap 8 is provided with circular holes which are concentric with the pile head double nut holes, the circular holes have the same diameter with the pile head double nut holes, and positioning pins 5 are installed between electrodes 6 and the insulating sleeve 3. The utility model can bear a bending moment and torsional force, the utility model can be vertically installed, and is suitable for horizontally installation. The utility model can be used as a lightning arrester, and can be used as a stanchion insulator. The utility model has the advantages that the utility model can simplify the device, save space, and reduce cost.
Description
The utility model discloses a kind of column support type composite insulation metal oxide arrester, is applicable on the power circuit, belongs to the protective device in the electric power transmission ﹠ distribution.
Common valve type band gap lightning arrester FS-2 can only do vertical installation, even the no gap silicon rubber synthesizing zinc oxide lightning arrester HYW-12.7/50 that is just promoting the use of at present, can not level install, anti-twist property is poor, can not bear bending moment and torsion, lightning arrester and post insulator can not be united two into one, promptly not only make lightning arrester but also make post insulator and use.Have to increase other element for satisfying lightning-arrest mounting condition, make whole arrester device complexity, it is bigger to occupy the space, and expense is higher.
The purpose of this utility model, a kind of column support type composite insulation metal oxide arrester is provided, it has solved lightning arrester mounting condition requirement harshness, especially can level install and double as post insulator and can bear certain bending moment and torsion, thereby simplified arrester device, save the space, reduced expense.
The utility model is to realize like this, its heart core is made up of the well behaved metal oxide valve block 1 of volt-ampere, outer edge high strength insulating sleeve 3,3 of valve block 1 and sleeve pipes are filled synthetic rubber resilient coating 2, outermost layer is an insulating barrier 7, be made up of synthetic rubber, two ends are electrodes 6, are provided with the two screwed holes 9 of pile crown on the electrode.Make the lightning arrester over-voltage better performances of valve block with metal oxide, and the high strength insulating sleeve is difficult for deforming, and can bear bigger bending moment and torsion, makes lightning arrester can bear deadweight when level is installed, can bear certain external force bending moment.When making lightning arrester be subjected to torsion, relative rotation does not take place with sleeve pipe in electrode, and correspondence has been installed a pair of pilot pin 5 between every electrode and sleeve pipe.For preventing that metal oxide valve block pressure is excessive in the sleeve pipe, on sleeve pipe, be provided with a pair of pressure relief opening.For solving the whole possibility that rotation takes place of lightning arrester, and can bear certain torsion, two bolt metal pile heads are all adopted at the utility model two ends, rotation can not take place when adopting this pile crown that lightning arrester is installed, and the spacing that fixation can not take place to cause because of rotation is yet changed.For making synthetic rubber and electrode contact position not have aqueous vapor to infilter, added a cover the stainless steel metal lid at the end face of lightning arrester, push in the synthetic rubber lateral, Qi Gai edge and fixedly seal.Because the utility model column support type synthesis of metal oxide lightning arrester intensity height is not yielding, therefore under the situation that is subjected to bending moment and torsion, can keep the electric property of lightning arrester constant.The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing is the orthogonal view of column support type synthesis of metal oxide lightning arrester.
With reference to the accompanying drawings, the utility model column support type synthesis of metal oxide lightning arrester is made up of outpacking rubber 7, two ends are metallic sealed cover 8 and two bolt pile crown, electrode 6 is convex cylindrical bodies, on the screwed hole 9 of two bolt pile crowns is arranged, pile crown bolt one end passes metallic sealed cover, closely be connected on the electrode by screwed hole, electrode normally is made up of aluminium or other metal, and the utility model inside is multi-disc cylinder metal oxide valve block 1,3rd, the high strength insulating sleeve, the 4th, the pressure relief opening that is provided with on the sleeve pipe, the 5th, the pilot pin of fixed electrode and sleeve pipe, the 2nd, the resilient coating between sleeve pipe and valve block is filled synthetic rubber.Length, diameter and the relative position of the length of this lightning arrester, diameter and pile crown bolt is also different according to different needs specifications.
Claims (3)
1, a kind of by metal oxide valve block heart core, electrode, the column support type composite insulation metal oxide arrester that uses on the power circuit that insulating case and metal cover are formed, it is characterized in that metal oxide valve block heart core 1 outer edge high strength insulating sleeve 3,3 of heart core 1 and sleeve pipes are filled synthetic rubber resilient coating 2, the two ends of outermost layer insulating case 7 and heart core 1 are convex cylindrical body electrodes 6, electrode 6 and insulating case 3 and 7 cooperate for the face of cylinder, electrode end surface is provided with the two screwed holes 9 of pile crown, have on the metallic sealed cover 8 outside the electrode and the concentric circular hole of the two screwed holes of pile crown with the footpath, electrode 6 and insulating sleeve 3 cooperate installing and locating bolt 5
2, column support type composite insulation metal oxide arrester according to claim 1 is characterized in that the line of centres of the two screwed holes 9 of pile crown on the two end electrodes 6 can horizontal or vertically be arranged mutually,
3, column support type composite insulation metal oxide arrester according to claim 1 and 2 is characterized in that high strength insulating sleeve 3 has pressure relief opening 4.
