Description

Charged the tearing open of a kind of 10kV taken cable buttock line arc suppression reactor
Technical field
The utility model relates to a kind of distribution line live working instrument, relates in particular to charged the tearing open of a kind of 10kV and takes cable buttock line arc suppression reactor.
Background technology
Now, overhead transmission line go into ground speed constantly accelerate, cable line was the trend of growth in the electric company's scope that has in recent years.In order to improve power supply reliability, following need of work uninterrupted operation: one, the needs of circuit variation; Two, need to dwindle the power failure scope in the power cut construction; Three, the needs of distribution system supply power mode temporary variations; Four, the needs of cable unit equipment change.More than work all to relate to and tear, take the outlet cable open.
Owing to there is capacitance current, can produce certain electric arc charged when tearing, taking the outlet cable open, and 10kV line unit complexity, phase spacing is little, and the phase spacing of cable end is littler, if carry out extinguishing arc with the extinguishing arc rope simply as power transmission sequence, is easy to cause phase fault or single-phase earthing, and the operating personnel is nearer from arcing distance, and the flash burn accident easily takes place.Therefore before tearing, take the outlet cable open, need arc arrester is installed earlier, and lead is connected by arc arrester with cable, can play the arc extinguishing effect effectively when dismounting or spliced cables go between like this, guaranteed operating personnel's personal safety.
In view of the foregoing, then drainage thread need be used on arc arrester, in addition, if drainage thread adopts plain conductor, then it is withstand voltage, dielectric strength is not enough, must install other insulation measures additional to lead-in wire during operation, extremely inconvenient, and brought hidden danger to safety work.Yet do not have supporting drainage thread on the arc arrester of the prior art, so prior art more and more can not satisfy the requirement of distribution line live working in the electric power system.
The utility model content
In order to overcome the deficiency that above-mentioned prior art exists, the utility model aims to provide charged the tearing open of a kind of novel 10kV and takes cable buttock line arc suppression reactor, used existing arc arrester and lead when tearing, taking the outlet cable tail open with solution, the problem that can not meet the demands when cable is connected.
Charged the tearing open of a kind of 10kV described in the utility model taken cable buttock line arc suppression reactor, comprise insulating bar, arc-control device, extinguisher switch and plug-in strip, it also comprises a drainage thread and a single ditch wire clamp, wherein, described drainage thread comprises core, be rolled in the outer insulating barrier of this core and be connected to the connecting ear at described core two ends, described single ditch wire clamp comprises hook binding clip, cardan and the short insulating bar that connects from top to down, and the two ends of described drainage thread link to each other with the hook binding clip with described plug-in strip by connecting ear respectively.
Owing to adopted above-mentioned technical solution, the utility model is by installing supporting drainage thread and single ditch wire clamp additional, solved the problem that lead-in wire connects in the arc suppression reactor use, industrial frequency withstand voltage reaches 45kV*min, easy to connect, safe and reliable, tear, take outlet cable buttock line for the 10kV circuit is charged open necessary condition is provided.
Description of drawings
Fig. 1 is a kind of charged structural representation of taking cable buttock line arc suppression reactor of tearing open of the utility model;
Fig. 2 is the A-A view of Fig. 1.
Embodiment
As shown in Figure 1, the utility model, be that a kind of charged tearing open taken cable buttock line arc suppression reactor, comprise insulating bar 1, arc-control device 2, extinguisher switch 3, plug-in strip 4, drainage thread 5, single ditch wire clamp 6 and link up with 7, wherein, drainage thread 5 comprises core 51, be rolled in the outer insulating barrier 52 of this core 51 and be connected to the connecting ear 53 at core two ends, single ditch wire clamp 6 comprises hook binding clip 61, cardan 62 and the short insulating bar 63 that connects from top to down, and the two ends of drainage thread 5 link to each other with hook binding clip 61 with plug-in strip 4 by connecting ear 53 respectively.
Drainage thread 5 insulating barriers 52 voltage endurance capabilities are 45kV*min, meet GB/T18037-2000 and electrical safe working order promulgated by the ministries or commissions of the Central Government electrical test standard-required about insulating tool.
Arc suppression reactor described in the utility model should check that before installation extinguisher switch 3 and plug-in strip 4 are in unzipped positions.Single ditch wire clamp 6 is suspended on the outlet cable joint, insulating bar 1 by link up with 7 hang up lead after, earlier plug-in strip 4 is closed, then extinguisher switch 3 is placed on closed position, constitute an interim path.If remove the outlet cable tail, then there are two current paths simultaneously between two tie points this moment---line route, drainage thread path, this moment, the open-circuit line lead-in wire can not produce electric arc; If then there has been the drainage thread path in overlap joint outlet cable tail between two tie points this moment, when the overlap joint lead-in wire, can not produce electric arc.Lead-in wire remove finish or overlap finish after, earlier extinguisher switch 3 is adjusted in unzipped positions, and then is drawn back plug-in strip 4, single ditch wire clamp 6 is taken off from cable end, and hangs on the insulating bar 1, at last insulating bar 1 is taken off from lead.
The utility model should be positioned in the special-purpose chest in transportation, and separate with metal tools and to deposit, prevent that grazing from damaging insulated part, reduces dielectric strength, and every year must carry out the test of preventative, inspectability to drainage thread, prevent that insulation damages from causing operating accident.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.
