The yoke plate realizes live replacement of 220 kV double-bundle conductor tension insulators, saves time and labor in work, and is safe and reliable.
Description
Technical field
Utility model belongs to electric power transmission line maintenance tool technical field of structures.
Background technology
The transmission line long-time running is in the field, the insulator of circuit is because of the effect of bearing power-frequency voltage, atmospheric over-voltage, switching overvoltage and mechanical load for a long time and the influence of external environment, null value, low value in various degree can occur or dodged by thunderbolt etc., reduce the insulation level of circuit, influence safety, the stable operation of transmission line.For this reason, in the maintenance of transmission line, often need to change insulator.In recent years, 220kV circuit employing double bundle conductor has become the main wire laying mode of 220kV circuit, and when changing the 220kV double bundle conductor strain insulator, the power failure operation of need operating a switch usually influences the normal operation of transmission line.But the means of still not having charged for replacement 220kV double bundle conductor strain insulator at present.
Summary of the invention
But the purpose of this utility model is the instrument that a kind of charged for replacement 220kV double bundle conductor strain insulator is provided in order to solve the deficiencies in the prior art, guarantees transmission line safety replacing insulator under the situation of normal operation that do not have a power failure.
The purpose of this utility model is achieved by the following technical solution.
But the yoke plate of charged for replacement 220kV double bundle conductor strain insulator, this yoke plate comprise arm-tie and the screw mandrel that laterally is coupled to each other; Outer end at arm-tie and screw mandrel is symmetrically installed with relative connecting plate, offers connecting hole at the free end of connecting plate.
Connecting plate described in the utility model is a L type connecting plate.Arm-tie, screw mandrel, connecting plate are insulator.
When changing the insulator operation, can be installed on the utility model on two yoke plates that insulator is installed on the transmission line earlier by connecting hole, tighten up screw mandrel tension connecting plate by adjusting, thereby two yoke plates of insulator are installed in tension, the horizontal loading of the insulator that need are changed shifts, and keep the bigeminy Board position stable, with this understanding, change insulator.
The utility model has been realized the charged for replacement of 220kV double bundle conductor strain insulator, and operation process is time saving and energy saving, and is safe and reliable.
Further set forth content of the present utility model below in conjunction with Figure of description and embodiment.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram when utilizing the utility model to change the insulator operation.
Embodiment
As shown in Figure 1, the utility model comprises arm-tie 1 and the screw mandrel 2 that laterally is coupled to each other; Outer end at arm-tie and screw mandrel is symmetrically installed with relative connecting plate 3, offers connecting hole 4 at the free end of connecting plate.Connecting plate 3 is a L type connecting plate, and the one end is connected by screw 5 with arm-tie, and the other end offers connecting hole 4.Arm-tie 1, screw mandrel 2, connecting plate 3 are insulator.
As shown in Figure 2, by assembly two yoke plates 7 with one group of installing hole 10 are installed on electric power tower cross-arm 6, insulator 8 is installed on two yoke plates, insulator 8 is installed on two yoke plates 7 by insulator pin 9.When needs are changed insulator 8, operation as follows:
(1) electrician, equipotential electrician wear tower on a complete set of qualified screening clothing on the tower, and equipotential electrician enters electric field along insulator string or from insulated flexible ladder;
(2) electrician, equipotential electrician cooperate on ground electrician and the tower, the utility model is hung rise to job position;
(3) electrician cooperates with the equipotential electrician on the tower, the installing hole on the connecting hole on the connecting plate 34 and two yoke plates 10 is aimed at and is connected with bolt, and the electrician finely tunes and tightens up screw mandrel 2 on the tower then, and the yoke plate integral position is aligned;
(4) electrician, equipotential electrician cooperate on ground electrician and the tower, the bottle supporting frame 11 that is loaded with new insulator is winched to job position, and its two ends reliably are installed on two yoke plates 7 by installing hole;
(5) electrician regulates once more and tightens up screw mandrel 2 on the tower, makes the insulator that will change loose, and electrician, isopotential electrical work point are not extracted the insulator pin 9 of insulator both sides on the tower;
(6) electrician, equipotential electrician, ground electrician cooperate the replacing poor insulator on the tower, new insulator is installed on two yoke plates by the insulator pin, and the insulator of changing is positioned on the bottle supporting frame 11.
(7) electrician, equipotential electrician's cooperation are freed the utility model and two yoke plates, and instruments such as the utility model, bottle supporting frame are reached ground on the tower.
(8) tower under electrician, the equipotential electrician on the tower, end-of-job.
Adopt the utility model, the insulation arm-tie is installed in the outside of insulator string, by tightening up screw mandrel, the horizontal loading that insulator is born shifts; Solve horizontal loading with the bottle supporting frame and shift the vertical load that the back own wt produces, controlled tractive effort simultaneously; Insulator disengaging and lead is electrically connected the most at last.Adopt the operational method of the utility model charged for replacement insulator, freeing when being specially adapted to charged for replacement 220kV double bundle conductor strain insulator.
