Abstract
The invention discloses an insulating skeleton which is provided with a layered threading structure, wherein a wire inlet and a wire outlet of each threading phase are arranged in a layered manner, and the height between layers is different, i.e. the wire inlet and wire outlet of a tooth part of the insulating skeleton are designed into different height so that the three-phase threading is well layered. Thus, the fire strike of the threaded flexible wire resulting from contact can be avoided, and the reliability of a concentrated coil motor can be improved.
Description
[technical field]
The present invention relates to machine field, refer in particular to a kind of insulation framework that is applied in the stator end of concentrating the volume motor.
[background technology]
Concentrate the volume motor to have simple in structure, reliable with respect to traditional induction machine; Volume is little, and is in light weight; Loss is few, and therefore the efficient height is extensive use of.Insulation framework is the overhang insulation that is used for concentrating the volume motor, and has the moulding of string-passing structure design, and its structural design directly influences the reliability of motor.At present there is the situation of contact friction between the inlet line of each phase and the egress line in the insulation framework of using, cross the also contact sparking easily of line yarn, certain potential safety hazard is arranged, make and concentrate the volume motor aspect reliability, to fail to satisfy the demand, it still has very big room for promotion, in addition, the insulation framework consumptive material that uses is more at present, and production cost is higher relatively.Have again, because of needs are equipped with groove paper in core interior, the structure of existing insulation framework, its cell wall the phenomenon of covering stator groove fully can occur not after covering groove paper, has influenced the insulation effect of stator slot greatly.
Based on above reason, provide a kind of insulation framework safe and reliable, that insulation effect is good, production cost is lower real for necessary.
[summary of the invention]
The object of the present invention is to provide a kind of reliability height, insulation framework that insulation effect is good.
Another object of the present invention is to provide a kind of economical with materials, insulation framework that production cost is lower.For realizing the object of the invention, provide following technical scheme:
A kind of like this insulation framework is provided, and this insulation framework design has the stratification string-passing structure, and the incoming line and the line outlet layering of crossing each phase on the line are provided with, and the height between each layer does not wait.On described insulation framework, be provided with U, the V of three layers of setting of branch, the incoming line and the line outlet of W three-phase power line, described U phase line is arranged at ground floor, described V phase line is arranged at the second layer, and described W phase line is arranged at the 3rd layer, every two-layerly separate by described boss is alternate.Be further clear layering, also designed boss in outer wall differing heights position, it is well arranged to make three-phase cross line.Can avoid line yarn contact sparking like this, improve the reliability of concentrating the volume motor.
For saving material, can design incoming line on the insulation framework wall and line outlet on same opening on the other hand, save the material cost of insulation framework.
Further, be provided with the lead-out wire opening in the lead-out wire position of this insulation framework wall, clamping tool is avoided at when coiling winding lead-out wire that repeatedly rubs, thereby is guaranteed that lead-out wire is not scratched from insulation framework wall opening stretching lead-out wire during coiling.
Further, the cell wall of this insulation framework is provided with groove paper limited step, and to guarantee the position of groove paper, the high unity of notch and cell wall place groove paper is avoided the incomplete covering stator groove of groove paper, improves the insulation effect of stator slot.
The present invention also provides a kind of concentrated volume motor, comprises stator, rotor, also comprises the aforesaid insulation framework that is used for described stator end.
The contrast prior art, the present invention has the following advantages:
Insulation framework design of the present invention had the line hierarchy, made three-phase cross the line stratification, had avoided crossing line yarn contact sparking, increased the protection to enamelled wire, had improved the reliability of concentrated volume motor.In addition, on the basis of satisfying the line requirement,, saved material cost by the improvement of incoming line and the same opening of line outlet.The also design by groove paper limited step, the insulation effect that has further improved.

Fig. 2 is the lead-out wire place schematic diagram of insulation framework of the present invention;
Fig. 3 is the groove paper card bit architecture schematic diagram of insulation framework of the present invention.
[embodiment]
See also Fig. 1, insulation framework of the present invention is provided with at the incoming line of crossing each phase on the line and line outlet layering, and the design of the height between each layer does not wait.Also designed boss in outer wall differing heights position, it is well arranged to make three-phase cross line.
A place opening is the inlet wire and the line outlet of A phase among Fig. 1, B place opening is the inlet wire and the line outlet of B phase, C place opening is the inlet wire and the line outlet of C phase, a1, a2, b1, b2 are the layering boss that A crosses line mutually, b1, b2, c1, c2 are the layering boss that B crosses line mutually, and c1, c2 are the layering boss that C crosses line mutually.
Cross line and see Fig. 1, direction is an example with A from left to right mutually, A crosses line 1 mutually in the superiors, incoming line on the insulation framework wall and line outlet are designed to an opening, and the tooth outer wall is provided with two-layer boss a1, a2, b1, b2, on first tooth after intact, cross line to the four teeth from the line outlet outlet and at the insulation framework wall, enter from incoming line, on the 4th tooth,, cross line to the seven teeth from the line outlet outlet and at the insulation framework wall around intact line, enter from incoming line, behind intact line, finishing on the 7th tooth.Below B cross line 2 mutually and cross line 3 same principles mutually with C and carry out stratification.
Incoming line on the insulation framework wall and line outlet are designed to an opening, 4., 5., 6. locate opening as the 4th, 5,6 teeth sign among Fig. 1, are respectively the inlet wire and the line outlet of A, B, C phase, cross line and enter from the left side of opening, behind intact line again from the right side outlet.Save the material cost of insulation framework.
Lead-out wire position at this insulation framework wall is provided with the lead-out wire opening, see also the lead-out wire opening 4 that Figure 2 shows that A, B, C three-phase, clamping tool is from insulation framework wall opening stretching lead-out wire during coiling, avoids when coiling the winding lead-out wire that repeatedly rubs, thereby guarantees that lead-out wire is not scratched.
See also Fig. 3, the cell wall of this insulation framework is provided with groove paper limited step 5, and to guarantee the position of groove paper, the high unity of notch and cell wall place groove paper is avoided the incomplete covering stator groove of groove paper, improves the insulation effect of stator slot.
The above is preferred embodiment of the present invention only, and protection scope of the present invention is not limited thereto, and anyly all belongs within the protection range of the present invention based on the equivalent transformation on the technical solution of the present invention.
