Abstract

The utility model discloses a phase modulation stator goes out notch fixed knot and constructs, it comprises notch cushion, sloping block, ligature rope, pressure finger, gumming dacron felt, through compressing tightly the both sides line stick with the sloping block wedge between two notch cushion, becomes a whole with notch cushion and sloping block ligature through ligature rope, is convenient for support the end with notch cushion support on the boss cushion through add the boss cushion on the pressure finger, has prevented the radial drunkenness of notch cushion. The utility model discloses simple reliable, with low costs, convenient to use can effectively improve the line stick integral rigidity and the reinforcing that go out the notch position and bear the ability of electromagnetic force under the accident.

Description

Stator notch outlet fixing structure of phase modulator

The technical field is as follows:

the utility model relates to a phase modulation stator goes out notch fixed knot and constructs.

Background art:

the stator winding end part can vibrate when a large-scale steam turbine generator operates, particularly when the generator is subjected to frequent impact load or short-circuit accidents and the like, the vibration can possibly cause the stator winding end part to generate mechanical damage under the action of powerful electromagnetic force, the normal operation of the generator is influenced, the most easily damaged parts are always positioned at the slot outlet of a coil bar, the stator slot and the stator end part can be better fixed, the stator coil bar at the slot outlet is in a suspended state, the structure is relatively thin, once the generator has an accident, mechanical damage often occurs at first. Generally, a large generator reinforces a stator bar at a slot outlet of the stator bar, improves rigidity between the bars at the slot outlet, and enhances the capability of bearing electromagnetic force under an accident.

The invention content is as follows:

the utility model aims at disclosing a phase modulation machine stator goes out notch fixed knot and constructs, technical scheme is: by the notch cushion, the sloping block, tie up the rope, the pressure indicates, the gumming dacron felt is constituteed, the notch cushion is the insulating part, the section is fluted, the sloping block is the insulating part, the shape is trapezoidal, it has welded the boss cushion to indicate to press, the sloping block is installed between the recess of two notch cushion cross-under, the support end of notch cushion supports on the boss cushion, the gumming dacron felt is installed between notch cushion and stator bar, prop open and compress tightly both sides stator bar with two notch cushions through the wedging sloping block, it is fixed with the sloping block ligature to tie up the notch cushion through tying up the rope.

The technical effects are as follows:

the utility model discloses a compress tightly both sides line stick with the sloping block wedge between two notch cushions, become a whole with notch cushion and sloping block ligature through tying up the rope, be convenient for support the end with notch cushion support on the boss cushion through add the boss cushion on the pressure indicates, prevented the radial drunkenness of notch cushion, can effectively improve the line stick global stiffness who goes out the notch position and the reinforcing ability of bearing the electromagnetic force under the accident after using this structure between all adjacent line sticks of play notch position.

FIG. 2 is a side view of a slot outlet fixing structure

FIG. 3 is a pocket block diagram

FIG. 4 is a side view of a pocket block

FIG. 5 is a perspective view of the inclined block

The specific implementation mode is as follows:

as shown in fig. 1, fig. 2 shows a stator notch outlet fixing structure of a phase modulator, which is composed of notch cushion blocks 1, an oblique block 2, a binding rope 3, a pressure finger 4 and a gumming polyester felt 5, wherein a boss cushion block 7 is welded on the pressure finger 4, the oblique block 2 is installed between grooves 6 buckled oppositely by the two notch cushion blocks 1, a supporting end 8 of the notch cushion block 1 is supported on the boss cushion block 7, the gumming polyester felt 5 with the compression deformation characteristic is installed between the notch cushion blocks 1 and stator bars 9, the two notch cushion blocks 1 are supported and pressed tightly by the wedging oblique block 2, and the notch cushion blocks 1 and the oblique block 2 are bound and fixed by the binding rope 3.

As shown in fig. 3 and 4, the slot block 1 is an insulating member and has a groove 6 in a cross section.

As shown in fig. 5, the swash block 2 is an insulating member and has a trapezoidal shape.

By applying the structure between all adjacent stator bars at the slot outlet position, the integral rigidity of the stator bar at the slot outlet position can be effectively improved, and the capability of bearing electromagnetic force under accidents is enhanced.

Finally, the scope of protection of the present invention is not limited to the embodiments described above. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
