Description
Technical field
The utility model relates to a kind of high-voltage electric power circuit service kit, relates in particular to carrying out a kind of instrument that 220kV transmission line V-type insulator string more changes jobs.
Background technology
In transmission line construction,, prevent to cause that because windage yaw causes conductor galloping line tripping fault, circuit have adopted V-type insulator string (as shown in Figure 1) in order to reduce phase windage yaw in the lead.Establish progressively perfectly along with the transmission line network, use the quantity of V-type insulator string also more and more in the 220kV transmission line.For improving power supply reliability, after thunderbolt, bird pest etc. cause the line insulator flashover, all need in time to change insulator, and because the V-type insulator string has certain angle, in promoting the lead process, insulator string is influenced by self gravitation to cause bunch of insulator to be deformed into arc and can't break away from upper and lower hanging point, and this carries out the hotline maintenance operation for the V-type insulator string and has brought sizable difficulty, and a lot of shaft tower V-type insulator strings are changed and must be adopted the power failure operating type.In the time of need changing the V-type insulator string when breaking down,, have to take the methods such as replacing or equal potential working that have a power failure, cause circuit reliability to descend and the security risk increase owing to there is not an instrument or an equipment that overlaps special use can realize charged for replacement.If adopt live line working, must make new tool.
Summary of the invention
The purpose of this utility model is to provide a kind of 220 kilovolts of jigs that transmission line charged for replacement V-type insulator string is used, and this jig provides advantage for realizing safe live line working.
To achieve these goals, the technical solution of the utility model is: 220 kilovolts of jigs that transmission line charged for replacement V-type insulator string is used, it is characterized in that it comprises the card body, the left part of card body has first notch, have first bolt hole with the first notch vertical direction, first bolt hole is connected with first notch; The right part of card body has second notch, has second bolt hole with the second notch vertical direction, and second bolt hole is connected with second notch; The bottom of card body has the yoke plate slot, has pin hole with yoke plate slot vertical direction, and pin hole is connected with the yoke plate slot.
The beneficial effects of the utility model are: adopt on the card body first notch, second notch, yoke plate slot are set; Insert in first notch, by bolt the lower end of first screw mandrel; Insert in second notch, by bolt the lower end of second screw mandrel; The upper end of first screw mandrel, second screw mandrel connects the cross-arm card respectively; During use, yoke plate inserts in the yoke plate slot of card body, passes eyelet (two eyelets are arranged on the yoke plate) on the yoke plate by latch then, and card body and yoke plate are fixed; Two cross-arm cards are separately fixed on first cross-arm, second cross-arm of iron tower, and the cross-arm card is that displacement is adjustable, and yoke plate is sling, and insulator string is relaxed; Make circuit operation maintenance band bit strip electricity operating personnel adopt the live line working mode to finish replacing, reduce the line outage time, improve the transmission line reliability 220kV transmission line V-type insulator string.The utility model provides advantage for realizing safe live line working.
