Description
Technical field
The present invention relates to a kind of electric operating instrument, specifically is a kind of charged for replacement 220kV straight line insulator string linkage type split-pin device.
Background technology
Along with the continuous growth of power load, regional power grid construction development is rapid, and the shaft tower of various forms model, lead wire and earth wire, insulator string and relevant auxiliary equipment occur in succession immediately.Very big change has taken place such as charged for replacement straight line synthetic insulator etc. to the demand of operation Work tool in high-tension line live line working in the past, and conventional operation Work tool can not satisfy the operation of changing some special shape insulator string and connecting gold utensil.
The ultra-high-tension power transmission line synthetic insulator is suspended on the electric power line pole tower, and cross-arm, lead by bulb, bowl a synthetic insulator and shaft tower link, and synthetic insulator has very high electric and mechanical strength, has guaranteed the reliability service of transmission line.Owing to reasons such as thunderbolt, pollution flashover, deteriorations, need change at any time in the running.For not because changing insulator with line outage, just need carry out live line working at ultra-high-tension power transmission line, directly contact high-voltage conducting wires or carry out operation by means of insulating tool by the operator, the composite insulator replacing of deterioration.Operation process is divided into substantially: 1, jig is installed; 2, line lifter is installed; 3, the spring catch (write off) between taking-up insulator string bulb and the wire clamp bowl head; 4, tighten up leading screw, lead is risen, make insulator string be relaxed state; 5, change.Because pole tower forms is various at present, has just occurred owing to the long action bars that causes the earth potential electrician can't independently use long length of shaft tower cross-arm length carries out the write off operation of above-mentioned steps 3.All be that cross-arm side electrician cooperates with shaft tower side electrician and carries out the write off operation at present, namely shaft tower side electrician is with split-pin device alignment springs pin, and cross-arm side electrician uses insulating bar to knock spring catch, just can fulfil assignment.Operation process is loaded down with trivial details, and has certain potential safety hazard, has prolonged the activity duration greatly.
Summary of the invention
The invention provides a kind of charged for replacement 220kV straight line insulator string coordinated type split-pin device, can make electrician one people independently finish the write off operation.
The present invention is achieved through the following technical solutions: a kind of charged for replacement 220kV straight line insulator string linkage type split-pin device, and it comprises operating head, insulating bar, connecting rod and operating grip, operating head is connected with operating grip by insulating bar, connecting rod; Described operating head comprises housing, is installed in cranking arm in the housing, curved arm rod, push rod and is fixed on to go up fork plate and lower fork plate on the housing one end both sides; The described fork plate of going up is that U-shaped, lower fork plate is L shaped, and a described end of cranking arm by curved arm rod and push rod flexibly connects, and at the front end of described housing jogger hole is arranged, the other end of described push rod pass jogger hole and can be in jogger hole before and after activity;
Described operating grip is made up of movable handgrip and integral cast handle, described movable handgrip elasticity is installed on the insulating bar, and by connecting rod and the flexible connection of cranking arm, described integral cast handle is fixed on the insulating bar, and the insulating bar other end is fixedly connected on the housing.
Principle is: the operating grip by on the control split-pin device action bars, and the push rod in the split-pin device operating head is leant out, spring catch is released tie point.Be used for getting spring catch and compare with action bars with existing, increased interlocking system, the operating personnel needn't be pounded out spring catch with self strength or double cooperation, only needs just spring catch to be released like a cork by the operation linkage.
The invention has the beneficial effects as follows: simple in structure, a people can operate, and is easy to operate, significantly reduced operation labor intensity and activity duration, and is conducive to the fail safe of line maintenance operation.
