Description
Technical field
The utility model relates in a kind of power industry and keeps in repair tool using, specifically a kind of instrument of dismounting PT insurance.
Background technology
Inductance type voltage transformer (claiming again PT) is the visual plant of transformer station, and it adopts electromagnetic induction principle that the high voltage of electrical network main equipment is converted to low-voltage.For preventing that the PT inductance coil from causing body to damage while internal fault occurring and fault enlarges, need to high pressure P T insurance be set at the PT mains side.The PT insurance is, in an insulating sleeve endoporus, a protective tube is set, and the tube wall of insulating sleeve presents the annular projection of a plurality of rules, forms the multiple tracks groove between projection.The electric conductor place at protective tube two ends is provided with spring, and the end cap of pressing spring is set at the two ends of insulating sleeve.In order better to be connected with end cap, respectively there is the together flange identical with insulating sleeve tube wall bulge-structure at the two ends of insulating sleeve, the inboard of flange is provided with catch, end cap is fastened on the outside of flange, between catch and end cap, be bolted, thereby end cap is fixed on to the two ends of insulating sleeve, and protective tube is compressed.Center at the lateral surface of end cap also is provided with boss with holes, for connecting electric wire.
At present electric power system 35kV equipment still be take outwork as main, and 35kV equipment PT protective tube fusing phenomenon happens occasionally, thereby to change protective tube be still commonplacely to work frequently.In the process of in the past changing protective tube, insulating sleeve vertically is arranged on electric pole, and between end cap and catch, spring is arranged, therefore at least need 2 people to carry out dismounting, people's both hands are held end cap and catch with a firm grip to keep invariant position between the two, another person is by the bolt between screwdriver dismounting catch and end cap, and there is following problem in it: need many people to carry out; Change one and insure mutually approximately 45～60 minutes consuming time; The 35kV of part transformer station voltage transformer framework can't be born many people's weight; Part transformer substation framework area is less, and the staff can't stand firm; Rely on the strength of staff's hand to overcome insurance top cover elastic force, be not easy the maintenance dynamics even, cause the screw unbalance stress, cause mounting process not high, likely cause insurance loose contact, insulating sleeve to enter the problems such as rainwater.
The utility model content
The utility model technical issues that need to address be to provide a kind of one man operation of being convenient to, operating time short, change the PT insurance replacer that efficiency is high.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
PT insures replacer, comprises the link be welded as a whole by mutually perpendicular horizon bar and vertical rod, the outer end of the described horizon bar adjusting screw(rod) parallel with vertical rod that be threaded; The right cutting ferrule of the fixing welding in below of the corresponding horizon bar in described vertical rod lower end, right cutting ferrule comprise the lower end that is welded on vertical rod vertical links, be connected to the right clip that is positioned at horizon bar below of interlinking lever end, right clip is for coordinating the semi arch structure that clamps insulating sleeve tube wall groove; Be flexibly connected a left cutting ferrule on right cutting ferrule, left cutting ferrule comprises the connecting rod parallel with the connecting rod of right cutting ferrule and fastens the left clip for circular semi arch structure with right clip.
Improvement of the present utility model is: the middle part of the connecting rod of described left cutting ferrule is fixedly welded with sleeve, and tie down screw is set in sleeve, and the position welding of the corresponding sleeve in the middle part of the connecting rod of right cutting ferrule locks the locking nut of screw rod.
Further improvement of the utility model is: the outer end of described adjusting screw(rod) and tie down screw is welded with the cross bar handle.
Further improvement of the utility model is: the fixing welding in the outer end of described horizon bar coordinates the adjusting nut of adjusting screw(rod).
Further improvement of the utility model is: the clip inboard of described right cutting ferrule and left cutting ferrule arranges some felt pads.
Further improvement of the utility model is: be welded with the positioner coordinated with left cutting ferrule on the connecting rod of described right cutting ferrule, positioner comprises the both sides up and down of two connecting rods that are vertically welded in respectively right cutting ferrule and hard metal bar or the sheet metal parallel with horizon bar.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
It is parallel with vertical rod by horizon bar that the utility model is established threaded adjusting screw(rod) screw thread, because vertical rod is vertical with horizon bar, adjusting screw(rod) is vertical with horizon bar, the active force that adjusting screw(rod) acts on the end cap of insulating sleeve is vertical single active force, therefore make the screw between catch and end cap stressed evenly, mounting process is high.Left cutting ferrule and right cutting ferrule clip fasten as circular, and right cutting ferrule and the flexible connection of left cutting ferrule, by regulating the tightness of right cutting ferrule and left cutting ferrule, make left cutting ferrule and right cutting ferrule well act on the groove of insulating sleeve tube wall, clamp insulating sleeve effective.By the cooperation of adjusting screw(rod), left cutting ferrule and right cutting ferrule, the screw between installation or removal catch and end cap, simple and convenient, single can completing.
The utility model is provided with through the sleeve at the connecting rod middle part that is welded on left cutting ferrule and the tie down screw that matches with the locking nut at the connecting rod middle part that is welded on right cutting ferrule, distance between the right cutting ferrule of free adjustment and left cutting ferrule, applicable to the dismounting of the insulating sleeve of different tube diameters.
Adjusting screw(rod) of the present utility model and tie down screw outer end are welded with the whippletree handle, and it only needs while using, and less power is rotatable tightens, time saving and energy saving.
The clip inboard of left cutting ferrule of the present utility model and right cutting ferrule arranges felt pad, while making left cutting ferrule and right cutting ferrule act on the groove on the insulating sleeve tube wall, and can the Damage to insulation sleeve pipe.
The connecting rod of right cutting ferrule of the present utility model is welded with positioner, while making cover be subject to tensile force as for the right cutting ferrule of insulating sleeve tube wall groove and left cutting ferrule, right cutting ferrule and left cutting ferrule are all the time in the same face, make left cutting ferrule and right cutting ferrule can, because unbalance stress is out of shape, not affect repeatedly use of the present utility model.
