Abstract
The invention discloses a kind of methods for avoiding water hydro-generator stator from interfering, described method includes following steps: 1) extracting water hydro-generator stator shape, lead-out wire (1) and nose (2) mapping are carried out, the main outside line size beta of interference region, β 1, β 2, B, R0, R1, R2 and R3 are obtained；2) extension line mapping is carried out to stator coil shape, obtains extension line a, b, c and a ', b ', c ' and A；3) by β numerical value change, whether judging interference.With the above mentioned technical proposal, the present invention has the advantages that easy to operate, time-consuming less, the present invention is researched and analysed by extracting the main relevant outer dimension of water hydro-generator stator, control stator coil nose angle of bevel range, it avoids it from being formed in assembling process with adjacent coil ends lead-out wire to interfere, this method mentality of designing is clear, and design principle is concise.
Description
Technical field
The present invention relates to a kind of methods for avoiding hydraulic turbine generator stator coil from interfering.
Background technique
Water hydro-generator stator is complex-shaped, is difficult to estimate it in assembling process in the conventional two-dimensional layout design stage
In whether will form interference between adjacent coil ends lead-out wire；It generally requires and 3-D geometric model is established with this to the coil
Judge interference problem, more time, energy and cost can be expended in this way.
Summary of the invention
It is an object of the invention to provide a kind of can to judge to avoid hydrogenerator whether interference by simply mapping
The method of stator coil interference.
It is realized the purpose of the present invention is technical solution in this way, one kind avoids water hydro-generator stator from interfering
Method, described method includes following steps: 1) extracting water hydro-generator stator shape, carry out lead-out wire and nose and make
Figure, obtains the main outside line size beta of interference region, β 1, β 2, B, R0, R1, R2 and R3；2) stator coil shape is extended
Line mapping, obtains extension line a, b, c and a ', b ', c ' and A；3) β is repaired whether judging interference by β numerical value change
Change, avoids interference with.
Wherein, in the step 1), β is stator coil nose angle of bevel, and β 1 is the right straight partial stator coil slot of coil
Center line and cross nose midpoint and cross the angle between rotation centerline, β 2 be the left straight partial stator coil groove center line of coil with
It crosses nose midpoint and crosses the angle between rotation centerline, B is nose thickness, and R0 is stator inner circle, and R1 is the right straight part of coil
The distance at bottom center to left straight portion top surface center, R2 are the left straight portion bottom surface center of coil to rotation center distance, and R3 is
The right straight portion bottom surface center of coil is to rotation center distance.
Wherein, in the step 2, stator coil nose and the direction lead-out wire thickness B is extended, extension line is obtained
A, b, c, while left side adjacent stators coil nose and lead-out wire thickness direction are extended, a ', b ', c ' are obtained, to extraction
The point in the line lower left corner is determined as A.
Further, in the step 3), by stator coil nose angle of bevel β numerical value change, A point meets at extension line
A ' is judged as interference, modifies, avoids interference with to nose oblique angle.
By adopting the above-described technical solution, the present invention has the advantages that easy to operate, time-consuming is less, the present invention is by mentioning
It takes the main relevant outer dimension of water hydro-generator stator to be researched and analysed, controls stator coil nose angle of bevel
Range avoids it from being formed in assembling process with adjacent coil ends lead-out wire and interferes, and this method mentality of designing is clear, and design is former
Reason is concise.
Detailed description of the invention
Detailed description of the invention of the invention is as follows:
Fig. 1 is stator coil outline drawing of the present invention；
Fig. 2 is that stator coil of the present invention extends line chart.
Specific embodiment
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing, but the present invention does not limit to
In these embodiments, any improvement or substitution on the present embodiment essence spirit still falls within the claims in the present invention and is wanted
Seek the range of protection.
Embodiment 1: as shown in Figure 1, a kind of method for avoiding water hydro-generator stator from interfering, the method includes such as
Lower step: 1) extracting water hydro-generator stator shape, carries out lead-out wire 1 and nose 2 is mapped, it is mainly outer to obtain interference region
Linear dimension β, β 1, β 2, B, R0, R1, R2 and R3；2) extension line mapping is carried out to stator coil shape, obtains extension line a, b, c
With a ', b ', c ' and A；3) it modifies, avoids interference with to β whether judging interference by β numerical value change.
Wherein, in the step 1), β is stator coil nose angle of bevel, and β 1 is the right straight partial stator coil slot of coil
Center line and cross nose midpoint and cross the angle between rotation centerline, β 2 be the left straight partial stator coil groove center line of coil with
It crosses nose midpoint and crosses the angle between rotation centerline, B is nose thickness, and R0 is stator inner circle, and R1 is the right straight part of coil
The distance at bottom center to left straight portion top surface center, R2 are the left straight portion bottom surface center of coil to rotation center distance, and R3 is
The right straight portion bottom surface center of coil is to rotation center distance.
As shown in Fig. 2, extending to stator coil nose and the direction lead-out wire thickness B, being prolonged in the step 2
Line a, b, c are stretched, while left side adjacent stators coil nose and lead-out wire thickness direction are extended, obtains a ', b ', c ', it is right
The point in the lead-out wire lower left corner is determined as A.
In the step 3), by stator coil nose angle of bevel β numerical value change, A point meets at extension line a ', is judged as
Interference, modifies to nose oblique angle, avoids interference with.
The present invention is not greater than the control of maximum permissible value to the nose oblique angle of stator coil, that is to say, that as long as nose is oblique
Angle beta value is less than the value, the interference situation between stator coil would not occurs.
