Abstract
A device for preventing a motor stator slot wedge from moving comprises a stator core; wherein, a groove is arranged on the stator core and is internally provided with a coil; slot insulation is arranged between the coil and the groove; a wedge is arranged at the opening of the groove; binding wires for preventing the slot wedge from moving are respectively arranged at both ends of the wedge and on vertical parts positioned at both ends of the coil and extending the stator core and form an enclosure. Binding units of the binding wires are more than one groove; binding wires of adjacent binding cross in a stagger way; the end of the slot insulation is provided with a downward turned-over edge as high as the wedge. In the invention, binding wires are added at both ends of the wedge and on the vertical parts at both ends of the coil and extending the stator core, thus preventing the slot wedge from moving, avoiding serious safe accidents such as creepage, ensuring reliable running of themotor and improving the degree of safety. The device is characterized by low manufacturing cost and simple process.
Description
Technical field
The present invention relates to the mobile device that prevents of a kind of motor stator slot wedge, particularly a kind of motor stator slot wedge.
Background technology
During the motor long-term work owing to reasons such as electromagnetic shocks, the slot wedge of motor can be moved, and then cause coil insulation bad, can cause serious security incidents such as electric leakage when serious, so the conventional practice is by the mode to the motor stator winding impregnating varnish coil and slot wedge to be fixed, as disclosing a kind of fixed structure for slot part of hydraulic turbine generator stator coil among the Chinese patent literature CN101304189A, comprise the stator core groove, be installed in the coil that is coated with the low resistance grey cloth in the groove, be installed in the coil bottom land filler strip of bottom portion of groove, be installed in two middle filler strips of middle low resistance glass cloth backing plate of groove and coil, be installed in the coil notch filler strip and the low resistance glass cloth backing plate of groove oral area, be installed in the slot wedge of groove oral area, and low resistance glass cloth cushion block and two low resistance glass cloth pads of being installed in coil lashing place, the bottom land filler strip, in ask the suitable type felt pan bar of polysulfones low resistance that filler strip and notch filler strip are dipping low resistance semiconductor lacquer.The low resistance glass cloth cushion block of coil lashing place and pad periphery also are lined with the suitable type felt pan bar of polysulfones low resistance of dipping paulownia horse glue and epoxide-resin glue.The impregnating varnish cost height of this stator coil slot part fixed structure, and need special equipment.
Summary of the invention
Purpose of the present invention aim to provide a kind of simple and reasonable, effectively prevent the mobile device that prevents of slot wedge moves, manufacture craft is simple, cost of manufacture is low, safe coefficient is high motor stator slot wedge, to overcome weak point of the prior art.
The mobile device that prevents by a kind of motor stator slot wedge of this purpose design, stator comprises stator core, stator core is provided with groove, coil is arranged in the groove, be provided with slot liner between coil and the groove, the opening part of groove is provided with slot wedge, it is characterized in that the two ends of slot wedge, stretches out at the two ends that are positioned at coil and be respectively arranged with the wiring that stops slot wedge to move on the upright position of stator core, and wiring constitutes fence.
The colligation unit of described wiring is more than one groove, and the wiring of adjacent colligation unit is staggered to intersect.
The present invention has increased wiring by the upstanding portion of stretching out stator core at the two ends of slot wedge, to the two ends of coil, stoped moving of slot wedge, prevented the generation of the security incident that electric leakage etc. is serious, guarantee the reliability service of motor, improved safe coefficient, on the basis of obtaining with the impregnating varnish effect same, it is low that it has cost of manufacture, the manufacture craft characteristic of simple.
Groove in the colligation unit among the present invention can be one, also can be two, and perhaps three, it has bigger flexibility and adaptability; The cost of material is low for wiring.
The present invention is applicable to single-phase asynchronous motor.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1-Fig. 3, this motor stator slot wedge prevent mobile device, stator comprises stator core 1, coil 2, slot liner 4, slot wedge 5 and lead-out wire 6, stator core 1 is provided with groove 10, coil 2 is arranged in the groove 10, and slot liner 4 is arranged between coil 2 and the groove 10, and slot wedge 5 is arranged on the opening part of groove 10, the two ends of slot wedge 5, stretch out at the two ends that are positioned at coil 2 on the upright position of stator core 1 and be respectively arranged with the wiring 3 that stops slot wedge 5 to move, wiring constitutes fence.The colligation unit of wiring 3 is a groove 10, sees Fig. 4, and perhaps, the colligation unit of wiring 3 is two grooves 10, sees Fig. 5,3 staggered the intersecting of wiring of adjacent colligation unit.
The end of slot liner 4 is provided with flange 4.1 down, sees Fig. 4 and Fig. 5.
Wiring adopts local colligation, and perhaps, colligation becomes a circumference.
