Description
Technical field
The utility model is related to a kind of anti-short-circuit generator stator core insulation structures.
Background technology
In each component of generator, stator core is an important component.The effect of stator core is to make the total magnetic of generator
It is logical to obtain the magnetic circuit of low magnetic resistance, while playing a part of fixed stator winding, in order to reduce eddy-current loss, iron core is divided into very
More thin slices (iron-core lamination), and it is insulated from each other between piece, to prevent from flowing through electric current between stack piece.During iron core closed assembly, yoke
Portion is generally fixed using support bar, and punching is likely to be broken with the insulation of support bar contact area, makes punching outside by support bar
Circle short circuit, so short-circuit between any place of stator core inner circle does not allow piece, when otherwise running, powerful main field is in iron core
Prodigious short circuit current is inside will produce, localized hyperthermia is caused to overheat and scaling loss iron core.In generator manufacture and operational process, due to
Thermal stress in technique dispersibility and operational process, mechanical oscillation influence, cause short circuit between iron core inner circle piece, cause iron core
Failure or even compressor emergency shutdown are scrapped, and loss is larger.Therefore, core inductance structure how is designed, short circuit between iron core inner circle piece is prevented
Caused by hot-spot, be core inductance design an important problem.
Since iron core outer circle is short-circuit by support bar, short circuit between any place's piece of inner circle can cause iron core short-circuit.
In generator product manufacturing and operational process, iron core inner circle can bear various stress, easy to produce short-circuit risks, cause
It is formed into a loop between lamination, causes iron core failure.
Invention content
The purpose of this utility model is to provide a kind of anti-short-circuit generator stator core insulation structure, to reduce iron core short circuit
Risk improves iron core reliability.
In order to achieve the above object, the utility model provides a kind of anti-short-circuit generator stator core insulation structure,
It is characterized in that, including stator core and support bar in stator core outer rim is set, be arranged between stator core and support bar
There is L-type insulation spacer.
Preferably, it is insulated by L-type insulation spacer between the stator core and support bar.
Preferably, the inner circle-line ring recess surface of the stator core is equipped at least one layer of insulated paint, the outside of insulated paint
Equipped at least one layer of low-resistance paint.
Compared with prior art, the utility model has the beneficial effects that：
The utility model structure is reliable, easy to operate, can be adapted for different grades of core inductance structure.This practicality is new
Type can overcome core inductance structure in current industry to be easy the short-circuit wind for causing hot-spot to cause iron core failure between interior disk
Danger, it is simple in structure, easy to operate, it is at low cost, improve product reliability.

Fig. 2 is enlarged drawing at A in Fig. 1；
Fig. 3 is enlarged drawing at B in Fig. 1.
Specific implementation mode
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
Embodiment
As shown in Figure 1, the anti-short-circuit generator stator core insulation structure of the present embodiment, including stator core 1 and set
The support bar 2 in 1 outer rim of stator core is set, as shown in Fig. 2, it is exhausted to be provided with 2 L-types between stator core 1 and each support bar 2
Edge gasket 3 is insulated between stator core 1 and support bar 2 by L-type insulation spacer 3.As shown in figure 3, the inner circle of stator core 1
Coil rooved face is equipped with one layer of insulated paint 4, and the outside of insulated paint 4 is equipped with one layer of low-resistance paint 5.
During iron core closed assembly, L-type insulation spacer 3 is arranged between stator core 1 and support bar 2, prevents stator core 1
It is short-circuit between outer circle vane；In interior round wires ring recess (teeth portion) surface spraying insulated paint 4 after the completion of closed assembly, 1 inner circle of stator core is prevented
It is short-circuit between punching, then low-resistance paint 5 is sprayed, ensure to be electrically connected between coil and punching.
By arranging L-type insulation spacer 3 between stator core 1 and support bar 2, it is ensured that have between 1 outer circle vane of stator core
There is good insulation performance.It under the conditions of this, even if generating short circuit between 1 punching of stator core, will not be formed into a loop, generate whirlpool
Stream loss, causes iron core failure.
