Abstract
The utility model relates to a secondary winding of an electromagnetic type current transformer for GIS (gas insulated switchgear), which aims to solve the problem that second windings are in comprehensive stress in the prior art. A wire is wound on a winding section of the secondary winding, at least three insulation pad groups are uniformly fixed on the circumference of an iron core and positioned on portions outside the winding section, and each insulation pad group comprises two insulation pads correspondingly arranged on the upper end face and the lower end face of the iron core. By the aid of the scheme, the insulation pads are stressed during assembly, transport and storage of the second winding, and pressure is averagely allocated on the insulation pads, so that the winding and the iron core are prevented from pressure action.
Description
Technical field
The utility model relates to the secondary winding of GIS with electromagnetic current transducer.
Background technology
GIS uses electromagnetic current transducer, in a highly fixing GIS cylindrical shell, is assembled together by several secondary winding stacks, and in the case, each secondary winding will be born the fastening pressure and the self gravitation of bolt, and long-term the use can the infringement secondary winding.In the prior art, mainly be between coil, to increase insulating barrier or resilient coating, to reduce the coup injury of secondary winding and to insulate.But this mode can make the coiling and the iron core of the winding of below bear bigger comprehensive stress owing to increased insulating barrier or resilient coating, and coiling and iron core possibly influence its electric property and electromagnetic property under extruding.
The utility model content
The purpose of the utility model provides the secondary winding of a kind of GIS with electromagnetic current transducer, receives the problem of comprehensive stress in order to secondary winding in the solution prior art.
For realizing above-mentioned purpose; The scheme of the utility model is: a kind of GIS is with the secondary winding of electromagnetic current transducer; At secondary winding coiling section winding lead; Iron core circumferentially evenly is fixed with at least three group cross-over block groups, and the cross-over block group is in the part outside the said coiling section, and every group of cross-over block group comprises that correspondence is arranged on two cross-over blocks on the iron core upper and lower end face.
Two cross-over blocks of said every group of cross-over block group are up and down over against setting.
Said cross-over block group is four groups.
Adopt the scheme of the utility model, in assembling, transportation and stressed because of cross-over block when storing, with the pressure mean allocation on cross-over block, thereby make coiling and iron core avoid the pressure effect.After several same specification products are assembled the GIS cylindrical shell of packing into together, each other also because of cross-over block stressed but the coiling and iron core avoid stress.Can not influence the ferromagnetic property of iron core and the electric property of coiling, its technical parameter remains unchanged basically after reaching GIS instrument transformer secondary winding assembling and accomplishing.
Description of drawings
Fig. 1 is the secondary winding vertical view of the utility model;
Fig. 2 is the end view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
As shown in Figure 1; 800,1000kV GIS Current Transformer secondary winding is big because of its volume, and sole mass is bigger, is protection product self; Assurance properties of product stability; On the iron core 1 of secondary winding, circumferentially evenly be fixed with four groups of cross-over block groups, the cross-over block group is in the non-coiling section (part outside the coiling section) of iron core, and every group of cross-over block group comprises that correspondence is arranged on two cross-over blocks 2 on the iron core upper and lower end face.Eight cross-over blocks of each secondary winding design receive comprehensive stress through cross-over block protection secondary winding coiling and secondary winding iron core.
Adopt the scheme of the utility model, in assembling, transportation and stressed because of cross-over block when storing, with the pressure mean allocation on cross-over block, thereby make coiling and iron core avoid the pressure effect.After several same specification products are assembled the GIS cylindrical shell of packing into together, each other also because of cross-over block stressed but the coiling and iron core avoid stress.
