Description

Laborsaving porcelain insulator null value band electro-detection spark fork instrument
Technical field
The utility model relates to a kind of electric system testing tool, relates in particular to a kind of laborsaving porcelain insulator null value band electro-detection spark fork instrument, is the charged testing tool of ultra-high-tension power transmission line porcelain insulator null value.
Background technology
At present, because transmission line of electricity power failure is planned less, porcelain insulator is carried out to charged testing very universal, band electro-detection generally adopts spark fork method to carry out, utilizing on the sub-sheet of good insulation exists voltage to distribute, to can there is the sound after this sheet insulator short circuit in spark fork, to judge whether null value of insulator.The method is the most effective charged judgement insulator zero method at present.But the method needs the long insulating bar of the workman hand-held 3m-5m of upper tower to operate (220kV-500kV is different according to tower window construction), the force and moment that spark fork produces can make workman tire out, and because of insulating bar long, under fatigue state of driver, insulating bar front end is shaken bad location, tired operation easily becomes dangerous factor, makes staff's personal safety have potential potential safety hazard.
Summary of the invention
In order to overcome large labour intensity that traditional spark fork clearance test brings to workman and the inconvenience of operation, the utility model provides a kind of laborsaving porcelain insulator null value band electro-detection spark fork instrument.Its objective is and provide a kind of simple in structure, safe and reliable, and can reduce the labour intensity that spark fork moment causes to workman, reduce spark fork front end and rock, improve a kind of spark fork instrument of the accuracy of location.
The utility model solves the technical scheme that its technical matters adopts:
Laborsaving porcelain insulator null value band electro-detection spark fork instrument is to be connected with metal sparks fork discharging gap at the leading section of insulating bar; Front portion at insulating bar is connected with set collar; In set collar, passed by insulating cord, and one end of insulating cord is connected with permanent magnet.
Described set collar is arranged on the insulating bar apart from the position of metal sparks fork discharging gap 3cm~5cm.
Described set collar metal set collar.
Described permanent magnet to the absorption affinity of iron between 100N~200N.
Described edge rope is silk insulating cord.
Described edge rope is the silk insulating cord of Φ 5mm~Φ 15mm.
Described edge rope is the silk insulating cord of Φ 10mm.
Described set collar be circular, square, rectangle, ellipse or abnormally-structured in one.
Advantage of the present utility model and beneficial effect are: by conventional insulators band electro-detection is hung to the mode of traction by insulating cord with spark fork front end, reduce the labour intensity causing to operating personnel because of spark fork moment; The problem that simultaneously reduces the shake of spark fork front end, improves the accuracy of location.In addition, adsorb the mode of steel tower with the mode of utilizing hook to hang Comparatively speaking by permanent magnet, the utility model also has easy to operate, and advantage simple in structure.Can improve greatly hot line job personnel's work efficiency, and the security of operating personnel's person is guaranteed.
Brief description of the drawings
Below in conjunction with drawings and Examples to further detailed explanation of the utility model.
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is the transverse part zoomed-in view of front end fixing metal ring.
In figure: insulating cord 1, insulating bar 2, metal sparks fork discharging gap 3, permanent magnet 4, set collar 5.
Embodiment
Embodiment 1:
The utility model is a kind of laborsaving porcelain insulator null value band electro-detection spark fork instrument, and as shown in Figure 1, the utility model is to be connected with metal sparks fork discharging gap 3 at the leading section of insulating bar 2, is connected with set collar 5 in the front portion of insulating bar 2; In set collar 5, passed by the silk insulating cord 1 of Φ 10mm, and one end of silk insulating cord 1 is connected with the permanent magnet 4 of strong magnetic force.The tail rope of silk insulating cord 1 causes workman's operation place and leaves the long nargin of certain rope along insulating bar 2, wants inspection survey insulator situation and determine in the time of concrete operations.
The structure of the set collar 5 described in the utility model is rectangle structure.
Described metal set collar 5 is arranged on the insulating bar 2 apart from the position of metal sparks fork discharging gap 33cm-5cm.Described permanent magnet 4 to the absorption affinity of iron between 100N~200N.
When concrete enforcement, first pitch the insulating bar front end of clearance test instrument at spark, apart from spark fork 3cm-5cm position, set collar is installed, one end is connected to the permanent magnet 4 of strong magnetic force, the Φ 10mm silk insulating cord that this permanent magnet 4 is advisable between 100N~200N to the absorption affinity of iron is through this ring, tail rope causes workman's operation place and leaves the long nargin of certain rope along insulating bar, and inspection is surveyed insulator situation and determined.After upper tower workman first lift bar by magnet adsorption to steel tower cross-arm above tested insulator, and progressively loosen traction rope, make spark fork front end fall to tested porcelain insulator place, workman is with a hand hold with a firm grip insulating bar and tail rope simultaneously, and another hand is controlled spark simultaneously and pitched the operation with electro-detection null value.In operation process, insulating cord, in tensioned state, only, in the time that needs move up and down spark fork, will be tightened up or be loosened by insulating cord.After the end of job, insulating cord is tightened up, spark fork rises near magnet positions, pulls at insulating bar and rope, and magnet comes off from steel tower, fulfils assignment and knocks off.For guaranteeing should to ensure insulating bar and rope insulation well before safety work.
When use, should be noted that, after upper tower workman first lift bar by magnet adsorption to steel tower cross-arm above tested insulator, and progressively loosen silk insulating cord 1, make metal sparks fork discharging gap 3 front ends fall to tested porcelain insulator place, workman controls insulating bar 2 simultaneously and then controls the operation of metal sparks fork discharging gap 3 with electro-detection null value with a hand hold with a firm grip insulating bar 2 and silk insulating cord 1 tail rope, another hand simultaneously.In operation process, silk insulating cord 1, in tensioned state, only, in the time that needs move up and down spark fork, will be tightened up or be loosened by insulating cord.After the end of job, insulating cord is tightened up, spark fork rises near magnet position, pulls at insulating bar and rope, and magnet comes off from steel tower, fulfils assignment and knocks off.
