Description
Technical field
The utility model relates to a kind of sliding support, specifically, relates to a kind of electric power system mesohigh SF that is used for
6The bracing or strutting arrangement of gas-insulated sealed tube bus belongs to electric power transmission support technology field.
Background technology
At present, state's inner high voltage SF
6Gas-insulated sealed tube bus is when installing and fixing support; Be connected between bus shell holder and the mounting bracket and mounting bracket and ground between be connected the general bolt that adopts and connect; Support perforate centre-to-centre spacing there is requirement; Poor to neutrality, unadjustable, be unfavorable for being connected between bus shell holder and the mounting bracket and mounting bracket and ground between be connected; Key is for high pressure SF
6Gas-insulated sealed tube bus is changed by ambient temperature and expanding with heat and contract with cold of producing almost do not have adjustable surplus, possibly cause bus structure when receiving variations in temperature, to be broken, and has potential safety hazard, reduces the security reliability of bus in electric power system.
The utility model content
The above-mentioned deficiency that exists to prior art, but the purpose of the utility model provides a kind of simple, good stability with low cost, rational in infrastructure, the big bidirectional modulation of install adjustment surplus, sliding support easy to wear, not easy for installation.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
A kind of sliding support comprises mounting bracket and bus shell holder, and mounting bracket is provided with four blocks, and its bus shell holder bilateral symmetry is provided with briquetting and two pads; Contact site with pad on said mounting bracket and the briquetting is provided with bond layer; Horizontal, vertical centering of said mounting bracket and bus shell holder; Be equipped with the hole on said briquetting and the mounting bracket, the position of opening of briquetting aligns with the position of opening of mounting bracket, clamps through screw bolt and nut between bus shell holder and the mounting bracket.
As further preferred version, described pad adopts polytetrafluoroethylene to process.
As further preferred version, described bond layer is the epoxy resin adhesive layer.
As further preferred version, described mounting bracket is fixed on the ground.
As further preferred version, be provided with packing ring between described bolt and the briquetting.
Compared with prior art, the utility model is confirmed the height of briquetting by the thickness of bus shell holder base plate, when making briquetting and mounting bracket fastening, can guarantee to clamp bus structure base plate and two pads; During the design of the axial width of bus structure base plate, consider the maximum displacement when bus is changed by temperature rise, bus shell holder base plate and briquetting, the pad above the mounting bracket are reliably contacted.But the sliding support that the utility model provides has simple, good stability with low cost, rational in infrastructure, the big bidirectional modulation of install adjustment surplus, advantage such as not easy to wear, easy for installation; The potential safety hazard that can effectively avoid bus structure when receiving variations in temperature, to be broken has improved the security reliability of bus in electric power system.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
To shown in Figure 8, a kind of sliding support that the utility model provides comprises mounting bracket 1 and bus shell holder 8 like Fig. 1, and mounting bracket is provided with four blocks 7, and its bus shell holder 8 bilateral symmetry are provided with briquetting 2 and two pads 3; Contact site with pad 3 on said mounting bracket 1 and the briquetting 2 is provided with bond layer; Horizontal, vertical centering of said mounting bracket 1 and bus shell holder 8; Be equipped with the hole on said briquetting 2 and the mounting bracket 1, the position of opening of briquetting 2 aligns with the position of opening of mounting bracket 1, clamps through bolt 4 and nut 5 between bus shell holder 8 and the mounting bracket 1; Said pad 3 adopts polytetrafluoroethylene to process, and bond layer is the epoxy resin adhesive layer; Said mounting bracket 1 is fixed on the ground, is provided with packing ring 6 between bolt 4 and the briquetting 2.
Be to smear epoxy resin adhesive in the scope between mounting bracket and the briquetting boss block 7 with the teflon gasket joint face earlier, so that fixing teflon gasket difficult drop-off is convenient to assemble with mounting bracket and briquetting; Again with horizontal, the vertical centering of mounting bracket and bus shell holder; Then the briquetting position of opening is alignd with the mounting bracket position of opening, connect with bolt and clamp bus shell holder and mounting bracket; Last mounting bracket is on ground, and good looking appearance, adjusting surplus sliding support big, wear-resistant, that frictional resistance is little, coefficient of safety is high have been accomplished like this.
The utility model is confirmed the height of briquetting by the thickness of bus shell holder base plate; When making briquetting and mounting bracket fastening, can guarantee to clamp bus structure base plate and two teflon gaskets, the bus structure bilateral symmetry is placed briquetting and teflon gasket; When the axial width of bus structure base plate designs; Consider the maximum displacement when bus is changed by temperature rise, bus shell holder base plate and briquetting, the teflon gasket above the mounting bracket are reliably contacted, owing to teflon gasket belongs to low-friction material; Sliding-frictional resistance is little, helps the bus shell holder and in sliding support, is free to slide.Teflon gasket makes to produce electrical isolation between bus shell holder and the mounting bracket for insulation, anti-aging material, thereby when the bus charging operation, making does not have induced current to flow through on the mounting bracket, has reduced the thermal losses of steel construction.High pressure SF like this
6Gas-insulated sealed tube bus is changed by ambient temperature and expanding with heat and contract with cold of producing can realize bidirectional modulation through sliding tray when normal charging operation, is broken to avoid bus structure.
Visible in sum: but the sliding support that the utility model provides has simple, good stability with low cost, rational in infrastructure, the big bidirectional modulation of install adjustment surplus, advantage such as not easy to wear, easy for installation; The potential safety hazard that can effectively avoid bus structure when receiving variations in temperature, to be broken has improved the security reliability of bus in electric power system.
Be necessary at last to be pointed out that at this; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also is not limited to above-mentioned giving an example, and those skilled in the art is in the essential scope of the utility model; The variation of having done, remodeling, interpolation or replacement all will belong to the protection range of the utility model.
