Description
Technical field
The present invention relates in a kind of power industry and keep in repair use instrument, the instrument of a kind of dismounting PT insurance specifically.
Background technology
Induction type voltage transformer (also known as 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.Causing body to damage and failure propagation when there is internal fault for preventing PT inductance coil, needing to arrange high pressure P T insurance at PT mains side.PT insurance arranges a protective tube in an insulating sleeve endoporus, and the tube wall of insulating sleeve presents the annular projection of multiple rule, forms multiple tracks groove between projection.The electric conductor place at protective tube two ends is provided with spring, arranges the end cap of pressing spring at the two ends of insulating sleeve.In order to better 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 inner side of flange is provided with catch, end cap is fastened on the outside of flange, be bolted between catch and end cap, thus end cap is fixed on the two ends of insulating sleeve, and protective tube is compressed.Boss with holes is also provided with, for connecting electric wire at the center of the lateral surface of end cap.
Current electric power system 35kV equipment is still based on outwork, and 35kV equipment PT protective tube fusing phenomenon happens occasionally, and thus changing protective tube is still commonplacely to work frequently.Changing in the process of protective tube in the past, insulating sleeve is vertically installed on utility poles, and have spring between end cap and catch, therefore 2 people are at least needed to carry out dismounting, people's both hands hold 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 it exists following problem: need many people to carry out; The caliber of insulating sleeve is not quite similar, and needs different dismantling devices; Change about 45 ~ 60 minutes consuming time of a phase insurance; Part transformer station 35kV voltage transformer framework cannot bear the weight of many people; Part transformer substation framework area is less, and staff cannot stand firm; Rely on the strength of staff hand to overcome insurance top cover elastic force, it is even to be not easy maintenance dynamics, causes screw unbalance stress, causes mounting process not high, likely cause insurance loose contact, insulating sleeve enters the problems such as rainwater.
Summary of the invention
The technical issues that need to address of the present invention are to provide one and are convenient to that one man operation, operating time are short, to change efficiency high, and the PT being applicable to different insulative sleeve pipe caliber insures replacer.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
PT insures replacer, comprises the link be welded as a whole by mutually perpendicular horizon bar and vertical rod, and the outer end of described horizon bar is threaded the adjusting screw(rod) parallel with vertical rod; The right cutting ferrule of the fixing welding in below of the corresponding horizon bar in described vertical rod lower end, right cutting ferrule comprises the vertical links of the lower end being welded on vertical rod, is connected to the right clip be positioned at below horizon bar of interlinking lever end, and right clip is coordinate the arcuate structure clamping insulating sleeve tube wall groove; Right cutting ferrule is flexibly connected a left cutting ferrule, and left cutting ferrule comprises the left clip of the connecting rod parallel with the connecting rod of right cutting ferrule and the arcuate structure equal with right clip radian;
The middle part of the connecting rod of described left cutting ferrule is fixedly welded with sleeve, arranges tie down screw in sleeve, and the position welding of the corresponding sleeve in middle part of the connecting rod of right cutting ferrule locks the locking nut of screw rod.
Improvement of the present invention is: the outer end of described adjusting screw(rod) and tie down screw is welded with cross bar handle.
Further improvement of the present invention is: the adjusting nut of welding cooperation adjusting screw(rod) is fixed in the outer end of described horizon bar.
Further improvement of the present invention is: arrange some felt pads inside the clip of described right cutting ferrule and left cutting ferrule.
Further improvement of the present invention is: the connecting rod of described right cutting ferrule is welded with the positioner coordinated with left cutting ferrule, positioner comprise two both sides being up and down vertically welded in the connecting rod of right cutting ferrule respectively and hard metal bar or sheet metal.
Further improvement of the present invention is: the clip also comprising the connecting rod of connecting rod for clamping right cutting ferrule and left cutting ferrule.
Another kind of the present invention improves and is: the clip of described left cutting ferrule and right cutting ferrule is fasten mutually as circular semicircular arc structure.
Owing to have employed technique scheme, the technological progress that the present invention obtains is:
It is parallel with vertical rod that the present invention establishes threaded adjusting screw(rod) to be threaded through horizon bar, because vertical rod is vertical with horizon bar, then 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 uniform force between catch and end cap, mounting process is high.Right cutting ferrule is flexibly connected with left cutting ferrule, by regulating the tightness of right cutting ferrule and left cutting ferrule, making left cutting ferrule and right cutting ferrule well act on the groove of insulating sleeve tube wall, clamping 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, singlely can to complete.
The present invention is provided with sleeve in the middle part of through the connecting rod being welded on left cutting ferrule and the tie down screw matched with the locking nut in the middle part of the connecting rod being welded on right cutting ferrule, distance between the right cutting ferrule of free adjustment and left cutting ferrule, is applicable to the dismounting of the insulating sleeve of different tube diameters.And due to the structure of left clip and right clip be arcuate structure, for being applicable to the dismounting of the insulating sleeve of different tube diameters, when regulating the distance between right cutting ferrule and left cutting ferrule, it is better that the clip of arcuate structure and the groove of insulating sleeve contact effect.
The connecting rod of right cutting ferrule of the present invention is welded with positioner, make to overlap when being subject to tensile force as the right cutting ferrule of insulating sleeve tube wall groove and left cutting ferrule, right cutting ferrule and left cutting ferrule are in the same face all the time, left cutting ferrule and right cutting ferrule can not be out of shape because of unbalance stress, affect and of the present inventionly repeatedly to use.
Adjusting screw(rod) of the present invention and tie down screw outer end are welded with whippletree handle, only need less power and rotatablely to tighten when it uses, time saving and energy saving.
Inside the clip of left cutting ferrule of the present invention and right cutting ferrule, felt pad is set, when making left cutting ferrule and right cutting ferrule act on the groove on insulating sleeve tube wall, can not Damage to insulation sleeve pipe.
The present invention is provided with the clip of the connecting rod of connecting rod for clamping right cutting ferrule and left cutting ferrule, when the arcuate structure of left cutting ferrule and right cutting ferrule is installed on insulating sleeve tube wall groove, clip and tie down screw double action are in cutting ferrule, and cutting ferrule better acts on insulating sleeve, clamping good fixing effect.
