Abstract
The utility model discloses a transformer bushing coil out installation rack which comprises a fixing circular disc, a pulling rope and a coil out fixing head. The front end portion of the pulling rope is fixed with the coil out fixing head. A rope penetrating hole is formed in the middle portion of the fixing circular disc. The transformer bushing coil out installation rack is characterized in that a fixed pulley is fixedly arranged on the fixing circular disc through a bearing, the front end portion of the pulling rope bypasses the fixed pulley and penetrates through the rope penetrating hole, three hinge seats are fixed on the periphery edge of the fixing circular disc in a symmetrical mode, each hinge seat is fixed with a fixed connecting rod through a pin shaft, the lower end of each fixed connecting rod is fixed with a locating plate, an arc-shaped sliding groove is formed in the middle portion of each locating plate, and the shape of each locating plate is one third of a circular ring. The transformer bushing coil out installation rack has the advantages of being simple in structure, low in cost, easy to install and capable of preventing coiling leads from being damaged in the process of installation of a transformer bushing, shortening installation time and improving maintaining efficiency.
Description
Technical field
The utility model relates to the aid of using when a kind of bushing shell for transformer outlet is installed, a kind of bushing shell for transformer outlet installing rack specifically, be beneficial in installation process, keep the level of sleeve pipe lead-in wire and insulator, play the reentrant bushing set-up time and the effect of the damage that prevents from going between.
Background technology
In the installation process of transformer, it is important link that bushing shell for transformer is installed, because bushing for transformer is guided to the fuel tank outside with the terminal of the high-low pressure winding of inside, play insulation against ground and the effect that lead-in wire is connected with external circuit, therefore, insulating sleeve must have electrical equipment intensity and the mechanical strength of regulation, electric conductor in the middle of the sleeve pipe also is the current-carrying original paper simultaneously, the load current that passes through for a long time in service, therefore must have good thermal stability, the moment when also needing to bear short circuit is overheated.In the bushing shell for transformer installation process, traditional mode is to hitch the winding outlet with pull rope one end, when sleeve pipe is in place, by pulling the winding terminal is pulled out, because the high and low pressure side sleeve pipe of 220kV transformer tilts with 45 degree and is installed on the fuel tank, cause winding outlet and internal surface of sleeve pipe friction in the process of pulling, if deviation appears in sleeve pipe angle in place, very easily cause the damage of winding leads, bury major safety risks in the future operation.
Summary of the invention
It is a kind of simple in structure, with low cost, easy and simple to handle that the purpose of this utility model is to provide, and can avoid the bushing shell for transformer outlet installing rack of damage outlet in the mounting sleeve process.
When pulling the winding outlet, relative fixing by the position that makes outlet and sleeve pipe, avoid damaging outlet in the mounting sleeve process.
In order to reach above purpose, the technical scheme that the utility model adopts is: this bushing shell for transformer outlet installing rack, comprise fixed disc, pull rope and outlet gland, the fixing upper outlet gland of the leading section of pull rope, the middle part of fixed disc is provided with lacing hole, it is characterized in that: on fixed disc, be fixed with fixed pulley by bearing, the leading section of pull rope is walked around fixed pulley, penetrate in the lacing hole, three free bearings on symmetrical fixing on all edges of fixed disc, fix upper stationary links by bearing pin on each free bearing, location-plate on fixing in the lower end of stationary links, the middle part of location-plate is provided with arc chute, described location-plate be shaped as 1/3rd annulus.
Described fixed pulley is provided with baffle plate.
The beneficial effects of the utility model are: simple in structure, with low cost, install easily, in the process that bushing shell for transformer is installed, avoided the damage winding leads, and shortened the set-up time simultaneously, improved overhaul efficiency.
Description of drawings
Fig. 1 is that structure master of the present utility model looks schematic diagram;
Among the figure: 1, fixed disc; 2, lacing hole; 3, fixed pulley; 4, free bearing; 5, stationary links; 6, location-plate; 7, arc chute; 8, pull rope; 9, outlet gland; 10, baffle plate.
Embodiment
Make the utility model with reference to accompanying drawing 1.This bushing shell for transformer outlet installing rack, comprise fixed disc 1, pull rope 8 and outlet gland 9, the fixing upper outlet gland 9 of the leading section of pull rope 8, the middle part of fixed disc 1 is provided with lacing hole 2, it is characterized in that: on fixed disc 1, be fixed with fixed pulley 3 by bearing, the leading section of pull rope 8 is walked around fixed pulley 3, penetrate in the lacing hole 2, three free bearings 4 on symmetrical fixing on all edges of fixed disc 1, fix upper stationary links 5 by bearing pin on each free bearing 4, location-plate 6 on fixing in the lower end of stationary links 5, the middle part of location-plate 6 is provided with arc chute 7, described location-plate 6 be shaped as 1/3rd annulus, can be combined into a whole annulus by three location-plates 6 like this, the outlet gland 9 of pull rope 8 front ends can be passed the middle through-hole of the annulus that is comprised of three location-plates 6.
Described fixed pulley 3 is provided with baffle plate 10, deviates from from the groove of fixed pulley 3 to prevent pull rope 8.
When using the utility model; pass the top that 3 arc chutes 7 are fixed on location-plate 6 bushing shell for transformer with bolt; the winding terminal is fixed on the outlet gland 9 of pull rope 8 front ends; pull rope 8 is walked around fixed pulley 3; the outer end of pull rope 8 is held by the operating personnel; after the sleeve pipe lifting beginning; the operating personnel passes sleeve pipe by pulling pull rope 8 with the winding terminal and pulls outward; because the utility model is relative with sleeve pipe fixing; can guarantee that in pulling process winding terminal remains on the centre position of sleeve pipe always; avoid with casing wall friction and extruding occuring, thereby protected the winding outlet to avoid damage.
