Abstract

The utility model relates to an overhead line drop out fuse fuse inspection tool belongs to power supply maintenance instrument technical field. Technical scheme is: contain main part sleeve pipe (1), draw -in groove (2), spring (3) and detect hook (4), draw -in groove (2) set up in the lower part of main part sleeve pipe (1), and detection hook (4) sets up on the upper portion of main part sleeve pipe (1), and spring (3) set up inside the main part sheathed tube, and between draw -in groove and the detection hook (4), the main part sleeve pipe interconnects through the top of draw -in groove and insulating pull rod. The utility model discloses a top is unciform inspection device, small portable, and the installation is swiftly convenient, and easily the personnel of rushing to repair judge the fault point, can effectively reduce the purpose that the danger coefficient reaches protection personnel, equipment and circuit safety in production during the operation, shorten emergency time in a large number, thereby can effectively avoid promoting operation and maintenance management unit and company's " breaking rate " performance assessment criteria because of the breaking that artificial work led to the fact in reduce loss.

Description

A kind of overhead transmission line fuse switch fuse checking tool
Technical field
This utility model relates to a kind of overhead transmission line fuse switch fuse checking tool, belongs to electric power repair technical field of tools.
Background technology
In distribution line (such as 10kV distribution line) works; it is frequently encountered by when blowing or virtually connect after transformator fuse switch electric fuse shields; owing to fuse is in open air, easy aging corrosion, fuse protective tube does not drop down the situation obvious cut-off point occur. Often this situation not easily passs through observation judgement, it is easy to cause emergency first-aid repair personnel to judge by accident, tends not to very first time discovery trouble point, so can extend emergency repair time in a large number, consume personnel's energy, waste corporate resource.
When repairing teams and groups judge and rush to repair this kind of fault, first, to assemble insulated tension pole, with pull bar by the fall insurance pipe of fuse switch by pulling open whether inspection fuse fuses (virtually connect and not easily check out) mutually. After finding problematic fuse, pull down and be replaced.
The personnel existed when carrying out this operation and equipment potential safety hazard: the first, not easily judge. This fault secure is exactly alike in appearance with the fuse being currently running. The second, complex operation. To be undertaken checking by phase opening and closing fall insurance pipe, judge, to analyze. Longevity of service (ordinary circumstance is on average at 15-20 minute) directly contributes the sale of electricity loss of my company. 3rd, very easily cause danger. The fuse switch having certain degree of aging just there will be fuse opening or virtually connects and fall insurance pipe metallic rod corrosion will not be fallen in draw-in groove, owing to fall insurance pipe fuses with body gold utensil corrosion adhesion, internal fuse or virtually connects, powerful arc light is very easily produced when opening and closing inspection, serious meeting causes single-phase or heterogeneous short circuit grounding fault, transformer body iron core winding persistently can be caused infringement by the dash current that moment produces, and also can impact circuit pole-mounted circuit breaker and make its action expand power failure range.Operation management unit and company is made to sustain a loss in each side such as power failure breaking examinations.
Utility model content
This utility model purpose is to provide a kind of overhead transmission line fuse switch fuse checking tool, by adopting top to be divided into hook-shaped inspection device, when without opening and closing fall insurance pipe, can check from protective tube bottom that the unci of device checks whether electric fuse fuses or virtually connect, and efficiently solves the problems referred to above existed in background technology.
The technical solution of the utility model is: a kind of overhead transmission line fuse switch fuse checking tool, comprise main casing body, draw-in groove, spring and detection hook, described draw-in groove is arranged on the bottom of main casing body, detection hook is arranged on the top of main casing body, spring is arranged on the inside of main casing body, between draw-in groove and detection hook, main casing body is interconnected by the top of draw-in groove with insulated tension pole.
Described draw-in groove is spring steel draw-in groove.
The beneficial effects of the utility model are: adopt top to be divided into hook-shaped inspection device; volume is little to be easy to carry; convenience quick for installation; it is prone to repair personnel's failure judgement point; can effectively reduce danger coefficient during operation and reach the purpose that protection personnel, equipment and line security produce; shortening emergency repair time in a large number, being prevented effectively from because the breaking caused that artificially works thus promoting operation management unit and company's " breaking rate " performance assessment criteria while reducing loss.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
In figure: main casing body 1, draw-in groove 2, spring 3, detection hook 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
A kind of overhead transmission line fuse switch fuse checking tool, comprise main casing body 1, draw-in groove 2, spring 3 and detection hook 4, described draw-in groove 2 is arranged on the bottom of main casing body 1, detection hook 4 is arranged on the top of main casing body 1, spring 3 is arranged on the inside of main casing body 1, between draw-in groove 2 and detection hook 4, main casing body 1 is interconnected by the top of draw-in groove 2 with insulated tension pole.
Described draw-in groove 2 is spring steel draw-in groove.
In actual applications, this utility model is spring steel material, and bottom is divided into spring steel clamp groove, and draw-in groove is stuck in insulated tension pole head by the used time; Top is divided into hook-shaped, the unci checking device can be utilized to check whether electric fuse fuses or virtually connect from protective tube bottom when without opening and closing fall insurance pipe.
