Abstract
The utility model relates to an axle hole fixing structure for an external slip ring outgoing line of a double-feed wind-powered motor, which comprises an inclined axle hole fixing cushion block, a cushion block on axle hole bottom, wedge-shaped cushion blocks around the axle hole, an axle hole central fixing cushion block and an axle hole central expansion steel rod, wherein each cushion block is made of epoxy glass fabric plate material having a slot on the center and can be used for clamping the slip ring outgoing line. The epoxy glass fabric cushion block is made of high pressure resistant materials, thereby further increasing the pressure resistance level. The axle hole fixing structure for the external slip ring outgoing line of the double-feed wind-powered motor has a simple, compact and reasonable structure, has obvious action effect, is conveniently detached, can be reused, and can be used for ensuring that the axle hole outgoing line has no fault within twenty years under the condition that the common epoxy glass fabric plate material is used.
Description
Technical field
The utility model relates to the fixed structure of the external slip ring lead-out wire of double-fed type wind power motor in axle, is mainly used in the insulation of the external slip ring lead-out wire of protection wind power motor, the lead-out wire damage in insulation that play causes in axle when avoiding owing to the rotor rotation.
Background technology
Motor is the device that electric energy and mechanical energy are changed mutually, is widely used in modern various machinery and the generating equipment.The double-fed type wind power motor belongs to wire wound asynchronous motor, its external slip ring lead-out wire, and main mode by the embedding armature spindle couples together rotor coil and slip ring, finally with rotor-side variable frequency device serial connection, realizes that rotor-side adds the function of AC excitation.
But the slip ring lead-out wire connects slip ring and rotor coil by the mode that embeds axis hole, in passing the process of axis hole, along with the high speed rotating of rotor and axial wall on every side touch, rub, causes the lead-out wire damage in insulation that the voltage breakdown accident finally takes place easily.
General winding motor cushions the impact between lead-out wire and axis hole wall by filling the suitable shape felt of polyester and wash glass rope clout in axis hole.Though this mode has been slowed down the destruction to insulation, but can't prevent lead-out wire trembling in axis hole, especially at the two poles of the earth, the frequency conversion generator of four utmost points, lead-out wire is thrown to a side of axis hole easily by centrifugal force, make the lead-out wire insulation directly in the face of the wearing and tearing of axis hole wall; Even in the process of filling the suitable shape felt of polyester, can't guarantee that also lead-out wire places the axis hole center, all be subjected to the protection of suitable shape felt all around.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point; thereby a kind of axis hole fixed structure of the external slip ring lead-out wire of double-fed type wind power motor that uses in the double-fed fan motor motor of high speed frequency conversion running is provided, guarantees that fixing of slip ring lead-out wire reaches the reliable of insulation.
The technical solution of the utility model is as follows:
The axis hole fixed structure of the external slip ring lead-out wire of a kind of double-fed type wind power motor, comprise inclined shaft hole fixedly correcting wedge, axis hole center fixation cushion block and axis hole center tensioner steel rod around the cushion block, hole heelpiece piece, hole, described inclined shaft hole fixedly around the cushion block, hole heelpiece piece, hole correcting wedge and axis hole center fixation cushion block combine, form the structure that matches with slip ring lead-out wire outline, the slip ring lead-out wire is clamped wherein; Described axis hole center tensioner steel rod is arranged in the axis hole, and the radial and axial location of slip ring lead-out wire is stuck.
Its further technical scheme is: described inclined shaft hole fixedly around the cushion block, hole heelpiece piece, hole correcting wedge and axis hole center fixation cushion block all adopt the epoxy glass fabric panel material to make.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, reasonable, action effect is obvious; The epoxy resin bonded fiber low price, draw materials easily, be applicable to and be processed into different shape, dimensional accuracy easily guarantees, and processing back quality is hard is not easy distortion, and itself is again high pressure resistant material, has guaranteed that the fixing and insulating effect of lead-out wire is reliable.This structure when assembling, utilize the tensioner effect of central steel rod, can guarantee that lead-out wire axially and radially all can't move, avoided the destruction of insulation; As long as extract steel rod out, total just can freely be fallen apart during dismounting, convenient for maintaining and allow repeatedly to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1 and Figure 2, the utility model combines with armature spindle 1, is used for fixing slip ring lead-out wire 2, comprises inclined shaft hole fixedly correcting wedge 5, axis hole center fixation cushion block 6 and axis hole center tensioner steel rod 7 around the cushion block 3, hole heelpiece piece 4, hole.The inclined shaft hole fixedly around the cushion block 3, hole heelpiece piece 4, hole correcting wedge 5 and axis hole center fixation cushion block 6 combine, form the structure that matches with slip ring lead-out wire 2 outlines, slip ring lead-out wire 2 is clamped wherein.Axis hole center tensioner steel rod 7 is arranged in the axis hole of armature spindle 1, and slip ring lead-out wire 2 radial and axial location are dead.
Except that axis hole center tensioner steel rod 7 is the ganoid round steel, other each cushion block: the inclined shaft hole fixedly around the cushion block 3, hole heelpiece piece 4, hole correcting wedge 5 and axis hole center fixation cushion block 6 be the epoxy glass fabric panel material of center grooved.Because above-mentioned axis hole lead-in wire filler adopts the expoxy glass cushion block to replace original old soft insulating material, reliable in structure is convenient, and effect is obvious, and axis hole lead failure rate can guarantee to be zero in 20 years.
The operation principle explanation: the utility model structure is pushed into hole heelpiece piece 4 the axis hole bottom earlier when assembling; Again correcting wedge 5 around the hole and axis hole center fixation cushion block 6 are clamped slip ring lead-out wire 2, tighten with the alkali-free glass silk ribbon on every side, integral body pushes axis hole.And slip ring lead-out wire 2 drawn from the inclined shaft hole, then with the inclined shaft hole fixedly cushion block 3 the inclined shaft bore portion of slip ring lead-out wire 2 is clamped and fixes; Cushion block is radial and axial in the axis hole at this moment still has living space, and lead-in wire can free play.Because the central part of axis hole center fixation cushion block 6 has been reserved circle hole groove one, available axis hole center tensioner steel rod 7 tips are knocked in, and slip ring lead-out wire 2 axially and radially just all can't move after the tensioner.When dismantling the utility model structure for maintenance, as long as utilize drawing screw in the axis hole center tensioner steel rod 7, just tensioner steel rod 7 can be extracted out, total just can easily be taken out.
Above-described only is the preferred implementation of the utility model structure, and the utility model is not limited to above examples of implementation.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection range of the present utility model.
