Abstract
The utility model provides a stator wire rod fastening structure. A wire rod is arranged in a groove of a stator iron core, a common groove wedge is arranged in the groove of the stator iron core, and an elastic corrugated packing strip used for preventing the wire rod from being loosened is arranged between the common groove wedge and the wire rod. Furthermore, a sunken-stopping groove wedge is arranged on the wire rod; the stator iron core is provided with a ventilation groove, and the sunken-stopping groove wedge is clamped in the ventilation groove of the stator iron core by a bayonet. The stator wire rod fastening structure has the following beneficial effects: the elastic corrugated packing strip is arranged between the common groove wedge and the wire rod, which can effectively prevent the wire rod from being loosened; the sunken-stopping groove wedge is arranged at a rabbet of the wire rod, which can effectively prevent the wire rod from being sunken.
Description
Technical field
The utility model technology relates to a kind of fastening structure of stator bar.
Background technology
Stator bar will bear electromagnetic force in generator operation and starting, stopping process, the comprehensive function of thermal effect and mechanical stress also will be born the vibration and the impact that take place under serious short-circuit conditions, and distortion and displacement may appear in stator bar.Therefore require the line rod to fix and do not produce problems such as the sinking of line rod, wearing and tearing and corona, galvano-cautery in reliable and the long-time running.Line rod straightway embeds in the iron core slot, and must make between line rod surface and the iron core cell wall has favorable mechanical contact, and the while, must make again between excellent outer surface of line and the iron core cell wall had good electric contact in order to prevent corona.The tightness of slot wedge is directly connected to the fastening of line rod, and therefore effectively line rod fastening system is very necessary.Stator bar fastening method comparatively commonly used in the tradition has: filler strip, auxiliary fixed form under slot wedge (comprising rise as high as the banks wedge and skewed slot wedge), the silicon rubber wedge.But these traditional stator bar fastening means all can not make stator bar keep permanent elasticity under the long-term pressurized and the effect of expanding with heat and contract with cold, and their compensation rate all is limited.Therefore hydraulic generator is after long-time running, and stator bar and slot wedge may produce loosening.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of stator bar fastening structure that is lined with elastic corrugated filler strip between common slot wedge and line rod is provided, and can prevent the loosening of stator bar effectively.
The utility model solves the technical scheme that its technical problem adopts: this stator bar fastening structure comprises the line rod, this line rod is located in the groove of stator core, be provided with common slot wedge in the groove of stator core, be lined with between common slot wedge and the line rod and be used for the loosening elastic corrugated filler strip of anti-principal vertical line rod.
Further, the line rod is provided with only deep gouge wedge; Stator core is provided with ventilation slot, ends the deep gouge wedge and is stuck in the ventilation slot of stator core by bayonet socket.
The effect that the utility model is useful is: the utility model fills up elastic corrugated filler strip between common slot wedge and line rod, can prevent effectively that the principal vertical line rod is loosening; Online rod goes out the notch setting and ends the deep gouge wedge, can prevent effectively that the principal vertical line rod sinks.

The structural representation that Fig. 1 looks for the utility model master;
Fig. 2 is the structural representation of the utility model side-looking.
Description of reference numerals: 1-line rod 2-ends the elastic corrugated filler strip 5-of the common slot wedge 4-of deep gouge wedge 3-stator core 6-ventilation slot 7-bayonet socket.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this stator bar fastening structure comprises line rod 1, ends deep gouge wedge 2, common slot wedge 3, elastic corrugated filler strip 4, stator core 5, ventilation slot 6 and bayonet socket 7.Stator bar 1 is embedded in the wire casing of stator core, and online excellent 1 goes out the notch place is provided with only deep gouge wedge 2, ends deep gouge wedge 2 and is stuck in by bayonet socket 7 in the ventilation slot 6 of stator core 5, can prevent effectively that principal vertical line rod 1 sinks; The elastic corrugated filler strip 4 of pad between 3 ends of common slot wedge and top bar 1 can prevent effectively that principal vertical line rod 1 is loosening.
The utility model technical pattern is simple, easy for installation, reliable; In the generating set long-time running, it is loosening that slot wedge occurs, and can come the retention wire rod to be in tightening state by flexible (thickness direction) compensation automatically of elastic corrugated filler strip.Obviously, elastic corrugated filler strip can keep permanent elasticity under the long-term pressurized and the effect of expanding with heat and contract with cold.This mode improves the generating set safe operation and has crucial meaning strengthening stator bar groove internal fixation.This mode can be widely used in the stator bar fastening means of large turbo-type generator and large-sized water turbine generator.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
