Abstract
The utility model discloses a current transformer overhauling device which is characterized in that universal wheels are respectively arranged on corners of an arch bracket; the lower end of a supporting rod is inserted in an inserted hole in the arch bracket; the upper end of the supporting rod is hinged with an overturning framework with a clamping hook; a limit stop lever is arranged on the overturning framework; and a maintainer disassembles auxiliary parts of a current transformer, then the telescopic supporting rod is inserted into the inserted hole of the arch bracket, the length of the supporting rod is regulated to enable the current transformer to be clamped in the overturning framework, a current transformer structure fixing screw is disassembled, the overturning framework is rotated, the limit stop lever is pressed against the supporting rod to enable the overturning framework to be at a horizontal position, a connecting wire on the current transformer is disassembled, the current transformer is replaced with a new current transformer, the connecting wire is installed, the new current transformer is clamped on the overturning framework and is rotated to the original position to be installed and fixed and the auxiliary parts are installed. The current transformer overhauling device has the advantages of convenience in carrying, simpleness and convenience for operation, safety for using and reliability for working.
Description
Technical field
The utility model relates to the power supply unit technical field, specifically a kind of current transformer apparatus for examination and repair of easy to carry, safe in utilization, reliable operation.
Background technology
As everyone knows; Present employed cabinet-type switch equipment; Account for the 10kV electric pressure and use more than 90% of Switch equipment; Current transformer (CT) is loaded on the framework of switch cubicle back, and two kinds of methods of general employing are changed it during damage: a kind of is that current transformer and framework are dismantled together, then current transformer is changed; Another kind is that current transformer is disassembled from framework separately, since general two phases of installing of current transformer, the big (20～25kg of weight own;), no matter be independent dismounting, still dismantle together with framework; Causing current transformer to come off easily hurts sb.'s feelings or self-inflicted injury; Particularly because construction space is limited, more current transformer dismounting causes inconvenience with fitting operation, and not having at present can the Current Transformer dismounting and the special tool utensil of installation; So the replacing of current transformer exists equipment and the great hidden that the person damages, do not meet State Grid Corporation of China's electric power safety working regulation regulation.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, provides a kind of and is easy to carry, the current transformer apparatus for examination and repair of easy and simple to handle, safe in utilization, reliable operation.
The utility model can reach through following measure:
A kind of current transformer apparatus for examination and repair; Be provided with tetragonal arch form support and retractable support bar; It is characterized in that being separately installed with universal wheel on the corner of arch form support, the support bar lower end is inserted in the spliced eye on the arch form support, and the upper end of support bar is hinged with the resupination framework of band grab; Resupination framework is provided with spacing pin, and spacing pin cooperates with support bar can make resupination framework be horizontal location.
The utility model can be provided with locating groove in the middle part of arch form support lower end, and during use, locating groove is stuck on the baffle plate of switch cubicle below, thinks that the arch form support positions.
When the utility model uses, new current transformer is put on the supporting bracket, be transported to below the current transformer that needs to change behind the switch cubicle; The maintainer lies on the supporting bracket current transformer accessory is dismantled; Then retractable support bar is inserted in the spliced eye of arch form support, the length of adjustable support bar is stuck in the resupination framework current transformer, removes current transformer structure fixed screw; The rotation resupination framework; The limiting block masthead makes resupination framework be horizontal level on support bar, and new current transformer and installation connection are changed in the wiring on the dismounting current transformer; To be stuck in resupination framework again and rotate back to original position and install and fix; Extract support bar then and let the maintainer lie on the supporting bracket to accomplish the current transformer appurtenances and install, install the arch form support that is loaded with old current transformer dragged away and get final product, have be easy to carry, easy and simple to handle, safe in utilization, reliable operation etc. advantage.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, a kind of current transformer apparatus for examination and repair is provided with tetragonal arch form support 1 and retractable support bar 2; Be separately installed with universal wheel 3 on the corner of arch form support 1, the structure of above-mentioned kind of part and the mutual downlink connection relation between them are identical with prior art, and this does not give unnecessary details; Support bar 3 lower ends are inserted in the spliced eye on the arch form support 1, and the upper end of support bar 2 is hinged with the resupination framework 4 of band grab, generally is provided with two support bars 3; Resupination framework 4 is provided with spacing pin 7, and spacing pin 7 cooperates with support bar 2 can make resupination framework 4 be horizontal location, also can on support bar 2, be provided with spacing pin 7; Spacing pin 7 can make resupination framework 4 be horizontal location, and the utility model can be provided with supporting bracket 5 on arch form support 1, convenient on the one hand installation, placement current transformer; Another has conveniently improved the bonding strength of arch form support 1 and the stability of work; In addition, the utility model can be provided with locating groove 6 in the middle part of arch form support lower end, during use; Locating groove 6 is stuck on the baffle plate of switch cubicle below, thinks that the arch form support positions.
When the utility model uses, new current transformer is put on the supporting bracket, be transported to below the current transformer that needs to change behind the switch cubicle; The maintainer lies on the supporting bracket current transformer accessory is dismantled; Then retractable support bar is inserted in the spliced eye of arch form support, the length of adjustable support is stuck in the resupination framework current transformer, removes current transformer structure fixed screw; The rotation resupination framework; The limiting block masthead makes resupination framework be horizontal level on support bar, and new current transformer and installation connection are changed in the wiring on the dismounting current transformer; Again new current transformer is stuck in resupination framework and rotates back to original position and install and fix; Extract support bar then and let the maintainer lie on the supporting bracket to accomplish the current transformer appurtenances and install, install the arch form support that is loaded with old current transformer dragged away and get final product, have be easy to carry, easy and simple to handle, safe in utilization, reliable operation etc. advantage.
