Abstract
The invention provides an installation tool for an overhead line fault indicator, which comprises an insulated tube, a spring which is installed in the insulated tube and an ear-shaped support which is fixedly installed on the external side of the insulated tube. A hook is arranged on the ear-shaped support. A conductive metal wire is additionally arranged on the external side of the insulated tube. By adopting the technical scheme, since one conductive metal wire is arranged on the external side of the insulated tube, the installation tool for the overhead line fault indicator has the beneficial effect that the damages caused to equipment and the potential safety hazards caused to operating workers by electric sparks produced during discharge are avoided through the discharge of the metal wire during equipment installation.
Description
Technical field
The invention belongs to the electric power system detection range, especially relate to a kind of overhead transmission line fault detector erecting tools.
Background technology
At the electric power system detection range, line-failure indicator can be installed on the overhead transmission line, on power cable and the switch busbar, be used to judge the circuit failed because.In case the circuit failed because, the line attendant can show by the red alarm of line-failure indicator, confirms short trouble section, branch and fault point rapidly.The retention time of alarm indication (also claiming resetting time) is according to requirement of client, during fabrication through adjustment line-failure indicator inner computer program setting.When the retention time arrives, if circuit has electricity, red alarm will disappear automatically, and line-failure indicator recovers normal condition.
Line-failure indicator erector prodigiosin is in the market realized charged installation simply and is plucked and unload, service free in the use.But in hookup wire line fault indicator process; Owing to be live line working, there are high low potential generation electric discharge phenomena in line-failure indicator and cable in contact process, be easy to generate electric spark; The one, equipment such as lesion wire line fault indicator, the 2nd, the operator is caused potential safety hazard.
Summary of the invention
The purpose of this invention is to provide a kind of overhead transmission line fault detector erecting tools that can protect equipment can protect personal safety again.
Technical scheme of the present invention is: overhead transmission line fault detector erecting tools; The ear shape that comprises insulating cylinder, is installed in the inner spring of insulating cylinder and is fixedly mounted on the insulating cylinder outside is supported; Said ear shape is supported and is provided with hook, and the said insulating cylinder outside also is provided with a conductive wire.
Said wire length is 1m-2m.
Said wire is a brass wire.
Said ear shape is supported for one or two.
Said insulating cylinder skin is an ambroin.
Said insulating cylinder bottom is provided with screwed joint, and said joint is combined with insulating bar.
Advantage and good effect that the present invention has are: owing to adopt the present technique scheme; At conductive wire of insulating cylinder arranged outside; Make in the erection unit process through discharge wiry, avoided because the electric spark that in discharge process, produces causes potential safety hazard to the infringement of equipment with to the operator.

Embodiment
As shown in Figure 1; First kind of execution mode of the present invention: overhead transmission line fault detector erecting tools; The ear shape that comprises insulating cylinder 1, is installed in the inner spring 2 of insulating cylinder 1 and is fixedly mounted on insulating cylinder 1 outside supports 3; Supporting 3 the shape of ear described in this execution mode is one; Ear shape is supported 3 and is provided with hook 4; The side that ear shape is supported close insulating cylinder 1 on 3 is provided with side hook 6, and insulating cylinder 1 outside also is provided with a conductive wire 5, and wire 5 length can be 1m-2m; Insulating cylinder 1 bottom also is provided with screwed joint 7, and joint 7 places are combined with insulating bar 11.As a kind of optimal way, the brass wire of choosing 1m is as conductive wire 5 in this example; Said insulating cylinder 1 skin can be ambroin.
In the installation process, like Fig. 1, Fig. 2, shown in Figure 3:
1) insulating bar 11 of screwing at screwed joint 7 places of insulating cylinder 1 bottom;
2) line-failure indicator is placed in insulating cylinder 1 chamber, 8 on line ball spring places ear shape to support 3 sides;
3) insert under line ball spring 8 front ends with instrument (can choose fork), will choose the fork fulcrum on spring shaft 9 with spring;
4) to choose the fork rear portion together cocked together with the moving plate 10 in loop with line ball spring 8 with defeating slightly, and with linking up with 4 line ball spring 8 hooked; Remove and choose fork;
5) holding insulating bar 11 aims at cable 12 with line-failure indicator card line opening and pushes away on firmly; Originally in cable 12 and line-failure indicator card line opening contact process; Cable 12 contacts with the brass wire top earlier and begins discharge; Electric spark owing to discharge generation in the process of slowly upwards lifting line-failure indicator is more and more littler; The electric spark of discharge generation disappeared basically when both contacted soon when line-failure indicator card line opening part and cable 12; Then line ball spring 8 will be clamped cable 12 with hook 4 disengagements automatically, and the moving plate 10 in loop also will automatically reset;
6) drop-down insulating bar 11 makes insulating cylinder 1 break away from line-failure indicator, accomplishes and installs.
As second kind of execution mode of the present invention: as shown in Figure 4; Overhead transmission line fault detector erecting tools adopts two ear shapes to support 3, and this execution mode is fit to install the line-failure indicator that has moving plate 10 in two pairs of symmetrical loops and spring shaft 9 as shown in Figure 5.In the installation process, like Fig. 4, Fig. 5, shown in Figure 6:
1) insulating bar 11 of screwing at screwed joint 7 places of insulating cylinder 1 bottom;
2) line-failure indicator is placed in insulating cylinder 1 chamber, two moving 10 of plates in loop place two ear shapes to support 3 sides respectively;
3) insert under moving plate 10 front ends in loop with instrument (can choose fork), will choose the fork fulcrum on spring shaft 9 with spring;
4) to choose the fork rear portion cocked with the moving plate 10 in two loops respectively with defeating slightly, and with hook 4 plate 10 is moved in the loop and hook; Remove and choose fork;
5) holding insulating bar 11 aims at cable 12 with line-failure indicator card line opening and pushes away on firmly; Originally in cable 12 and line-failure indicator card line opening contact process; Cable 12 contacts with the brass wire top earlier and begins discharge; Electric spark owing to discharge generation in the process of slowly upwards lifting line-failure indicator is more and more littler; The electric spark of discharge generation disappeared basically when both contacted soon when line-failure indicator card line opening part and cable 12; Then two moving plates 10 in loops will be automatically thrown off with hook 4 and are clamped 12, two loops of cable to move plate 10 heads relative;
6) drop-down insulating bar 11 makes insulating cylinder 1 break away from line-failure indicator, accomplishes and installs.
More than two embodiment of the present invention are described in detail, but said content only is preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
