Abstract
The utility model provides a kind of 110kV double loop Small Distance strain tower drainage thread insulation brace rod, by the insulating bar that middle-end is fiberglass epoxy resin filling foamed pipe processing and fabricating, the moving jaw (1) of front end and the leading screw (5) of end and angle steel fixture (4) combine, for solving the safety problem that live line working electric clearance is too small on the Small Distance strain tower of 110kV double loop, ensure that upper strata drainage thread can keep effective clearance of 2.2 meters with the spacing of the operating personnel being in lower floor's cross-arm, guarantee that live line working personnel can safe and reliable work.
Description
Technical field
The utility model belongs to a kind of high-voltage electric power circuit tools for live working, is specifically related to 110kV double loop Small Distance strain tower drainage thread insulation brace rod.Act on 110kV double loop Small Distance strain tower live line working electric clearance and cross minor issue, ensure that upper strata drainage thread can keep effective clearance of 2.2 meters with the spacing of the live line working personnel being in lower floor's cross-arm, guarantee that live line working personnel can safe and reliable work.
Background technology
110kV double loop Small Distance strain tower vertical arrangement is because of reasons in structure, two-layer cross-arm spacing is about 3.5 meters, upper phase drainage thread is 1.5 meters apart from hitch point vertical height, lower floor's cross-arm distance drainage thread is less than 2.0 meters, deduction live-working safety distance 1.0 meters, in replacing during phase insulator string, need operating personnel at middle phase cross-arm place standing operation.At this moment, human body enters the safe distance requirement that the scope of activities of carrying out operation below electric field can not meet live line working, and only reliable interruption maintenance just can complete defect elimination work.
Summary of the invention
In order to realize the purpose of this utility model, the technical scheme adopted is: a kind of 110KV double loop Small Distance strain tower drainage thread insulation brace rod, it is characterized in that: comprise the insulating bar that middle-end is fiberglass epoxy resin filling foamed pipe processing and fabricating, the moving jaw of front end, with, the leading screw of end and angle steel fixture; Moving jaw is made up of seaming and active tongue, relies on the movement of active tongue in seaming, realizes clamping multi-form catenary; Angle steel fixture is combined by sleeve, bayonet socket and butterfly nut and forms; Leading screw is made up of screw mandrel, nut and the sleeve combination that is connected with nut; Insulating bar can be that the insulating bar of diameter 44 millimeters and the insulating bar of diameter 32 millimeters are socketed to form by specification.
Insulation brace rod adopts high strength glass fiber reinforced plastic epoxy resin filling foamed pipe, be characterized in that intensity high insulation effect is good, surface is moistureproof, lightweight, convenient operation, further scheme is, insulating bar can be respectively two sockets of diameter 44mm and diameter 32mm by specification, be convenient to flexible dismounting and carry.
Insulation brace rod front end moving jaw adopts high-strength aluminum alloy material processing and fabricating, is suitable for multi-form suspension clamp and similar gold utensil thereof in actual track.
The leading screw of insulation brace rod end utilizes leading screw principle, is rotated promote the displacement that insulation brace rod changes wire jumper by shake screw mandrel.
For 110DSN, 110JGU1, 110JGU2, 110JGU3, 1H-SJ1, 1H-SJ2, 1H-SJ3, 1H-SJ4, 1N-SJG1, 1N-SJG2, the strain tower of the double loop Small Distance vertical arrangements such as 1N-SJG4, insulation brace rod is utilized to be provoked by drainage thread to during with cross-arm about 150 degree laterally, namely when upper phase drainage thread outwards supports from during to about 150 degree, the horizontal displacement of drainage thread minimum point is 1.5 meters, vertical height rises 1.2 meters, the minimum range now going up phase drainage thread Middle Phase cross-arm reaches 3.2 meters, deduction live-working safety distance 1.0 meters, the electric clearance of remaining 2.2 meters, be enough to the safe distance of live line working personnel on middle phase cross-arm during operation meeting normal height, effectively complete live line working.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the specific embodiment structural representation of the moving jaw in Fig. 1.
Fig. 3 is strut end screw mandrel specific embodiment structural representation in Fig. 1.
Embodiment
Contrast accompanying drawing to be below described in further detail the utility model embodiment.
Shaft design of the present utility model: as shown in Figure 1, adopt the processing of high strength glass fiber reinforced plastic epoxy resin filling foamed pipe. make, be characterized in that intensity high insulation effect is good, surface is moistureproof, lightweight, convenient operation and carrying, insulating bar is that diameter 44 millimeters of insulating bars 22 and diameter 32 millimeters of insulating bars 21 are socketed to form by specification, multiple spot perforation screw is fixed, and overall length length 2.9 meters-3.6 meters is adjustable, load 50 kilograms.Effective insulated lengths is greater than 2.0 meters.
Strut front end jaw design: adopt high-strength aluminum alloy material processing and fabricating, as shown in Figure 2, moving jaw 1 comprises seaming 11, active tongue 12, tongue handle 13 and active tongue are flexibly connected, and be connected with insulating bar front end by bolt 14, tongue handle 13 is provided with external screw thread, with the screw-internal thread fit on moving jaw, tongue handle 13 rotates and realizes the movement of active tongue 12 in moving jaw, can clamp multi-form catenary; Multi-form suspension clamp and similar gold utensil thereof is suitable in actual track.
Strut tail house designs: angle steel fixture 4 is combined by sleeve 41, bayonet socket 42 and butterfly nut 43 and forms, and bayonet socket 42, for blocking angle steel, holds out against with butterfly nut 43; As shown in Figure 3, leading screw 5 is combined by screw mandrel 52, nut 51 and the sleeve 41 that is connected with nut and forms.Insulating bar 22 is placed in sleeve 41, utilizes leading screw principle, swinging handle 53, thus promotes the displacement that insulation brace rod changes wire jumper, thus ensures 2.2 meters, the air gap that earth potential working personnel are enough, completes live line working.
Operation using method of the present utility model is as follows:
1) use the resistance value of pre-test insulation brace rod, be greater than 800 megaohms;
2) tower is fixed angle steel fixture;
3) with the main suspension clamp of strut front end jaw clamp card, hypomere is fixed on leading screw;
4) rotary screw rod, makes jumper string produce angle displacement;
5) measure earth potential working effective and safe distance, be greater than 1.3 meters, start live line working.
