Abstract
The utility model discloses a sliding type insulation supporting structure for telescopic hardware which is used in DC valve hall of the electric system. The sliding type insulation supporting structure is formed by arranging an insulation supporting rod which passes through a clamping head and is fixedly connected with an insulation disc arranged in a tubular bus, adding an insulation sleeve outside the insulation supporting rod at a part where the insulation supporting rod corresponds to the clamping head, and connecting the insulation sleeve with the clamping head to form an integrity through a fastening member. According to the insulation supporting structure, the clamping head can slides along the axial direction of the insulation supporting rod freely when the telescopic hardware completes the mechanical support of the tubular bus, the axial expansion and retraction of the tubular bus caused by factors such as thermal expansion and earthquake is overcame, and the electrical connection between an existing supporting rod of the telescopic hardware and the clamping head is cut off, thereby avoiding the accidents caused by possible overheat of the supporting rod of the telescopic hardware, and achieving the purpose of the utility model reliably; and the sliding type insulation supporting structure has the advantages of scientific and reasonable design, simple and practical structure, attractive and elegant appearance, stable and reliable performance, reduced maintenance cost, being suitable for industrial promotion and the like.
Description
Technical field
The utility model relates to a kind of supporting construction of flexible gold utensil.Be particularly related to a kind of insulating supporting structure that is applied to the flexible gold utensil that uses in the electric power system straight-wavy valve Room.
Background technology
Flexible gold utensil (also claiming expansion joint) is as a kind of link, it is bearing two electrical connection and mechanical connections between arrangement terminal in use, gold utensil is wanted to support the weight of institute's bonding conductor and the part weight of gold utensil itself, also will eliminate the displacement that causes due to reasons such as heat expansions simultaneously.The flexible gold utensil that now adopts is mainly by strutting piece, conductor and the deadweight of part gold utensil to be supported, and diversion function should be completed by flexible conductor.Strutting piece directly contacts with conductor, because strutting piece (metal parts) is the good conductor of electricity, and the structure of gold utensil and around electric field all very complicated, be subjected to the impact of " kelvin effect ", probably cause gold utensil strutting piece electric current excessive, cause that support temperatures exceeds standard, is out of shape, cause transformer station or current conversion station interruption of service to occur time and again.Cause power failure, bring great loss and inconvenience for user's productive life.
Summary of the invention
The utility model is to provide a kind of slidingtype insulating supporting structure of flexible gold utensil, after purpose is to solve flexible gold utensil and is subjected to the impact of " kelvin effect ", the accident that causes the excessive temperature exceeding standard distortion of gold utensil strutting piece electric current to cause, and bring the problem of great loss and inconvenience for user's productive life.
Scheme of the present utility model is as described below: it comprises tubular bus, chuck, pole and securing member, the insulation strut that passes chuck and be fixedly connected with set insulation cake in tubular bus by setting, and set up insulating case in the insulation strut outside of described insulation strut and chuck corresponding part, described insulating case is linked into an integrated entity through securing member and chuck realize.
The beneficial effects of the utility model: the supporting construction of having taked insulation cake and insulation strut composition due to this utility model, make flexible gold utensil that chuck is free to slide at the insulation strut axis direction, overcome the pipe bus axial stretching that the factors such as heat expansion, earthquake produce, and the electrical connection between the existing pole of the flexible gold utensil of cut-out and chuck, guarantee that the electric current of flexible gold utensil is without flexible gold utensil pole, avoid the overheated accident that causes of flexible gold utensil pole possibility, realized reliably goal of the invention.Have simultaneously that design science is reasonable, simple and practical, good looking appearance is generous, stable and reliable for performance, reduce maintenance cost, be fit to the advantages such as industry popularization.
Description of drawings
Fig. 1 is the utility model overall structure figure;
Fig. 2 is the local structure for amplifying schematic diagram of Fig. 1.
Embodiment
By Fig. 1, flexible gold utensil slidingtype insulating supporting structure shown in Figure 2, it is a kind of New insulated supporting construction that designs on the prior art basis.It has kept existing tubular type mother 1, chuck 4, securing member 5 and pole, but existing pole is conductive rod and directly fixing with chuck 4.The utility model is made as insulation strut 3 with pole, and former pole is extended and is fixed into one with the interior set insulation cake 2 of tubular bus 1 through securing member 5.Insulation strut 3 outsides at described insulation strut 3 and chuck 4 corresponding parts are provided with insulating case 6, and described insulating case 6 is connected to form one through securing member 5 and the outside chuck of insulating case 6.Simultaneously chuck 4 is connected by bolt with tube type bus.this supporting construction can make insulation strut 3 and insulation cake 2 be free to slide in insulating case 6 endoporus and tubular bus 1 respectively, when bearing mechanical load, remain insulation strut 3 and chuck 4, the insulation of insulation strut 3 and tubular bus 1, 6 liang of insulation cake 2 and insulating cases are located the strong point and have been fixed two degrees of freedom perpendicular to tubular bus 1, but decontroled the degree of freedom of tubular bus 1 axis direction, when insulation strut 3 and chuck 4 are realized mechanical support, guaranteed that insulation strut 3 and chuck 4 are at the free-extension of tubular bus 1 axis direction and both electric insulations, the reliable purpose that realizes invention.
