Abstract
The utility model discloses a rotor coil end-to-end joint sleeve, comprising an upper welding beam, a lower welding beam and a cross beam; wherein the upper end of the cross beam is connected with the middle part of the upper welding beam and the lower end of the cross beam is connected with the middle part of the lower welding beam; the cross section of the end-to-end joint sleeve is in H shaped. The rotor coil end-to-end joint sleeve has features of complete welding, good welding quality, reliable welding, and high connection strength of the rotor coil end.
Description
Technical field
The utility model relates to the also headgear that is used for the welded disk rotor end winding.
Background technology
Rotor coil is an important components in the generator, carries out energy converting between mechanical therein, and has rated current to pass through.Can its service behaviour not only is directly connected to generator safe operation, but also influences exerting oneself and efficient of generator.When making rotor, generally rotor coil is embedded in the rotor-body slot, end with two bundles or multi beam rotor coil welds together then, is connected with outer net by lead-in wire, wherein, the welding quality of rotor coil end is extremely important, if welding quality is bad, then ftracture easily in the end of rotor coil, and resistance increases, easily heating, thus useful life of generator influenced.
Traditional welding method is that direct end with rotor coil welds together, then at the end of rotor coil outer wrapping insulating barrier.This welding method, the bonding strength between the rotor coil end is low, therefore, ftractures easily.Subsequently, people utilize a kind of and headgear, with the end of rotor coil put into earlier and headgear in, welding then, the 24-25 page or leaf of 2002 the 01st phases of periodical " fire-proof motor " of publishing on March 21st, 2002 has disclosed rotor and the headgear Welding Structure is improved and the argon arc welding, the also headgear of two kinds of structures is disclosed, wherein a kind of cross section of structure of and headgear is " mouth " font, utilizes process this structure and headgear welded disk rotor overhang to be: earlier and headgear and rotor coil end zinc-plated, then rotor coil is put into and headgear in, squeezing into copper between rotor coil carves, weld then, when welding process, can only from and the two ends of headgear weld, like this, and the middle part of headgear and rosin joint can appear, through welding is poor, weld seam of poor quality, therefore, weld seam ftractures easily, and resistance is big, generates heat easily at weld, like this, the useful life of generator is short; The structure of another and headgear is to have the gap in the side of " mouth " font and headgear, and is just good at the through welding of gap location though this structure through welding is good, and, make easily and headgear ftractures.
The utility model content
The purpose of this utility model is for a kind of rotor coil and headgear being provided, utilizing structure of the present utility model, welding fully, through welding is good, welding is reliable, the bonding strength height of rotor coil end.
For achieving the above object, rotor coil and headgear comprise welded grider, following welded grider and crossbeam; The upper end of described crossbeam is connected with the middle part of last welded grider, and the lower end of crossbeam is connected with the middle part of following welded grider; Cross section described and headgear is " H " type.
Utilize said structure and during headgear welded disk rotor end winding, the rotor coil end is placed in the spatial accommodation of " H " type and headgear and welds, during welding, not only can from and the welding of the end of headgear, and can from and the side of headgear weld, like this, the area of welding is big, the phenomenon that rosin joint can not occur, weld seam are not easy to occur cracking, therefore, welding fully, through welding is good, and welding is reliable, the bonding strength height of rotor coil end.
As improvement, described welded grider, following welded grider and the crossbeam gone up is structure as a whole.The feasible also intensity height of headgear of integrative-structure.
Description of drawings
Fig. 1 is and the structure chart of headgear;
Fig. 2 for rotor coil be welded on and headgear on structure chart;
Fig. 3 is the structural representation of rotor.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Rotor coil as shown in Figure 1 and headgear, comprise welded grider 1, following welded grider 2 and crossbeam 3, the upper end of crossbeam 3 is connected the middle part of welded grider 1, the lower end of crossbeam 3 is connected down the middle part of welded grider 2, the described also headgear of going up welded grider 1, following welded grider 2 and crossbeam 3 formation " H " types, form first spatial accommodation 4 on the left side of crossbeam 3, form second spatial accommodation 5 on the right of crossbeam 3.In the present embodiment, and headgear be structure as a whole.
As shown in Figures 2 and 3, the end 6 of rotor coil is welded to and the process of headgear is: the rotor coil end is placed in first, second spatial accommodation of " H " type and headgear and welds, during welding, not only can from and the welding of the end of headgear, and can from and the side of headgear weld, like this, the area of welding is big, the phenomenon that rosin joint can not occur, weld seam are not easy to occur cracking, therefore, welding fully, through welding is good, and welding is reliable, the bonding strength height of rotor coil end.
Claims (2)
1. rotor coil and headgear is characterized in that: comprise welded grider, following welded grider and crossbeam; The upper end of described crossbeam is connected with the middle part of last welded grider, and the lower end of crossbeam is connected with the middle part of following welded grider; Cross section described and headgear is " H " type.
2. rotor coil according to claim 1 and headgear is characterized in that: described welded grider, following welded grider and the crossbeam gone up is structure as a whole.
