Description
Technical field
The utility model relates to a kind of electrician's instrument, specifically is the jig of suspension insulator in the middle of a kind of poling board method charged for replacement 500KV atypia tangent tower.Be particularly suitable for the middle suspension insulator of charged for replacement 500KV ultra-high-tension power transmission line atypia tangent tower.
Background technology
Along with the high speed development of power grid construction, the tower in the ultra-high-tension power transmission line emerges in an endless stream.In the design of circuit, take all factors into consideration the factors such as design feature of the residing geographical conditions of shaft tower, meteorological condition and shaft tower, often be not able to sometimes and adopt the atypia tower.The employing of atypia tower has brought certain difficulty to upkeep operation.
The lead list insulator string string of ultra-high-tension power transmission line is suspended on the electric power line pole tower.Insulator string is formed by multi-disc dish-type insulator head (bulb) tail (the steel cap of dribbling nest) serial connection, and insulator string 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; Owing to the variation of environment, the insulator string creep distance can not meet the demands simultaneously, also needs to change.For not because of changing insulator with line outage, just need on ultra-high-tension power transmission line, carry out live line working, directly contact high-voltage conducting wires or carry out operation by the workman by means of insulating tool, deterioration insulator is wherein changed, must use a kind of intermediate insulation, two has the special mould clamp of tightening device, and wire tension is transferred on the lifting tool, makes insulator string become relaxed state from tension (because of some tons weight of suspension lead makes insulator string be in tensioned state).Because the distribution of tower material is different with typical tangent tower on the atypia tangent tower cross-arm, causes on the cross-arm lifting tool to take root, thereby can't finish lifting.
Summary of the invention
The utility model provides the jig of the middle suspension insulator of a kind of poling board method charged for replacement 500KV atypia tangent tower, adopt novel jig that lifting tool is taken root on cross-arm, realize that two suspension centres carry out live line working and change the middle suspension insulator of 500KV atypia tangent tower.
The utility model is realized with following technical scheme: the jig of suspension insulator in the middle of a kind of poling board method charged for replacement 500KV atypia tangent tower, feature is made up of jig A and the jig B that matches with jig A, jig A comprises pedestal, dop, dop is vertically mounted on above the pedestal, the screw mandrel installing hole is arranged on pedestal and be fixed with the screw rod that stretches out to a side; Jig B matrix is a U-shaped, and the bottom of matrix is provided with the screw hole that matches with screw rod on the jig A.
The beneficial effects of the utility model are: simple in structure, easy to use, realize that two suspension centres carry out live line working and change suspension insulator in the middle of the 500KV atypia tangent tower, and protection each other, earth potential electrician operation be convenient, do not need the reinforcement of iron tower cross-arm.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 and Figure 2, the jig of suspension insulator is made up of jig A and the jig B that matches with jig A in the middle of the poling board method charged for replacement 500KV atypia tangent tower, jig A comprises pedestal 1-1, dop 1-2, screw rod 1-3, dop 1-2 is vertically mounted on above the pedestal 1-1, and screw mandrel installing hole 1-4 is arranged on pedestal, and screw rod 1-3 stretches out and is fixed on the pedestal 1-1 to a side.
As shown in Figure 3, Figure 4, jig B matrix 1-5 is a U-shaped, and the bottom of matrix is provided with the screw hole 1-6 that matches with screw rod on the jig A.
As shown in Figure 5, the concrete method of operation of using is: at first, the operating personnel is stuck in the dop 1-2 among the jig A of jig 1 at seam place on the angle steel of cross-arm on the tower, and the screw rod 1-3 among the jig A passes the working hole reserved on the cross-arm and the screw hole 1-6 among the jig B, and tightens fixing with nut.Leading screw installing hole 1-4 place among the jig A installs leading screw 2; To work the insulation pull-rod 4 that hangs up subsequently and four line devices 6 connect by screw.Equipotential electrician enters electric field along insulated flexible ladder 5, and equipotential electrician installs four line devices 4, and each sub-thread of conductors on quad bundled is entered in the hook of four corresponding line devices 4.The earth potential electrician begins to lift by crane leading screw 2, stops lifting after lifting by crane to a certain degree, makes insulator string lower end hanging point loose, and equipotential personnel extract the hanging point screw, begin to change insulator.
The step of changing the insulator operation is as follows:
1) the equipotential electrician enters electric field: the lifting insulated flexible ladder, the equal potential working personnel carry out electric field along rope ladder.The lifting insulated flexible ladder is fixed on the cross-arm insulated flexible ladder one end, and the other end ties up on the tower leg after straining by the insulation rope, and equal potential working personnel slowly enter in the highfield along insulated flexible ladder.
2) lifting lead: earth potential the electrician lift by crane by leading screw, and the earth potential electrician installs jig on cross-arm, and itself and lifting tool are linked together (lifting tool is leading screw and insulation pull-rod, four line devices); Under equipotential electrician's cooperation, determine to begin to use the leading screw stringing after lead enters in the hook of four line devices, make the porcelain vase string lax.
3) pluck screw: equipotential electrician pulls out the screw under the porcelain vase string, makes the porcelain vase string break away from lead.
4) pluck screw: the earth potential electrician will be insulated and be transmitted rope and tie up between first insulator of insulator string and second insulator, and the ground staff transmits by the insulation of strand grain and restricts, and makes the screw at insulator and cross-arm hanging point place loose.The earth potential electrician extracts the screw at cross-arm hanging point place.
5) the porcelain vase string that falls: the ground staff is by motor-driven strand mill loose insulator string slowly.
6) insert the insulation plate: the deterioration insulator in equipotential electrician's insulator string of etc.ing arrives lead when neighbouring soon, and the plate that will insulate rapidly is inserted in the insulator place below the deterioration insulator, and plate rests on the lead.
7) change the deterioration insulator: equipotential electrician unclamps deterioration insulator and whole connecting of going here and there, and takes the deterioration insulator, the connection of changing new insulator and recovering bunch of insulator.
8) recover connecting of insulator string and cross-arm: the ground staff has ground insulator string by motor-driven strand, and until the cross-arm place, the earth potential electrician recovers the Bolt Connection of itself and cross-arm.
9) recover connecting of insulator string and lead: the isopotential electrical union connects the bolt between insulator string lower end and yoke plate.
10) finish operation.
