Abstract
The utility model discloses a tension insulator replacement tool which is characterized in that the tool is provided with a supporting frame which supports a bottom of an insulator and a fixture which is connected to corresponding frame and conductive wire at two ends of the insulator. The fixture comprises a pair of frame fixtures (2), a conductive wire fixture (3) and a pair of insulation adjusting plates (4). The frame fixtures (2) are connected with one end of each of the insulation adjusting plates through tightening screw mandrels (5) with adjustable length. The conductive wire fixture (3) is a wing shape clamp which comprises a left wing (31), a right wing (32) and a clamping part (33) used for holding a conductive wire tightly. The left wing and the right wing are respectively connected with the insulation adjusting plates (4) which are positioned at two sides of the conductive wire fixture. According to the tension insulator replacement tool, a power cut range can be reduced, operation steps are simplified, working efficiency is raised, labor intensity of workers is reduced, the tool is suitable for the replacement of a substation bridge line insulator, and labor cost is greatly saved.
Description
Technical field
The utility model relates to high-tension line power equipment maintaining, upkeep operation instrument, specifically a kind of power tool for changing the overhead high voltage line strain insulator.
Background technology
Along with power consumption progressively increases, the transmission facility load constantly increases, 35 kilovolts, 110 kilovolts, aging, the heavy existing picture such as dirty in a large number appears in 220 kilovolts of insulators that wait transmission line, brings very large potential safety hazard to circuit, and can therefore increase and make an inspection tour and the workload of maintenance.Replacing insulator changes trouble very in many specific positions, thus extended interruption duration, strengthen personnel workload, reduced power supply reliability.
The utility model content
The utility model provides a kind of strain insulator to change instrument, to facilitate the replacing insulator operation for fear of the weak point that prior art exists.
The utility model technical solution problem adopts following scheme:
strain insulator is changed instrument, its design feature is, be provided with the holder flatrack that is supported on insulator bottom and be connected to framework corresponding to insulator two ends and the jig on wire, described jig comprises the framework jig, wire jig and insulation adjustable plate, described framework jig and insulation adjustable plate are a pair of, the framework jig is connected with insulation adjustable plate one end by the length-adjustable screw mandrel that tightens up, described wire jig is wing card, comprise a left side, right flank reaches the clamping part for the wire of holding with a firm grip, a described left side, right flank respectively be positioned at the ambilateral insulation adjustable plate that is connected of wire card and connect.
The utility model design feature also is:
Described tighten up screw mandrel by the screw mandrel one that connects the framework jig, connect the screw mandrel two of insulation adjustable plate one end, and form with screw rod bushing that screw mandrel one, screw mandrel two form threaded engagement, described screw rod bushing is provided with turning handle.
The replacing instrument also comprises a flat ladder, and a described flat terraced end is provided with hook.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model relies on the holder flatrack that the gravity of insulator is alleviated, alleviate the work load of personnel on tower. by jig, wire is fixed, can allow an impetus is arranged when the staff changes insulator on tower, shortened personnel's operating time on the tower, reduce the work high above the ground personnel, improved security performance.
2, the utility model can be changed the insulator of different electric pressures, and is simple and easy.
