Embodiment 1
[0013] Embodiment 1: as figure 1 As shown, a method for avoiding the interference of the stator coil of the hydro-generator, the method includes the following steps: 1) Extract the shape of the stator coil of the hydro-generator, draw the lead line 1 and the nose end 2, and obtain the main outer line of the interference area Dimensions β, β1, β2, B, R0, R1, R2 and R3; 2) Draw extension lines for the stator coil shape, and obtain extension lines a, b, c and a', b', c' and A; 3 ) Through the change of β value, judge whether there is interference or not, and modify β to avoid interference.
[0014] Wherein, in the step 1), β is the bevel angle of the nose of the stator coil, β1 is the angle between the center line of the stator coil slot at the right straight part of the coil and the midpoint of the nose end and the center line of the over rotation, and β2 is the coil The angle between the center line of the left straight part stator coil slot and the middle point of the nose en...

The present invention discloses a method of avoiding hydro-generator stator coil interference. The method comprises the following steps of 1) extracting the appearance of a hydro-generator stator coil, plotting a leading-out wire (1) and a nose end(2), and obtaining the main exterior line sizes beta, beta 1, beta 2, B, R0, R1, R2 and R3 of an interference area; 2) plotting the extension lines of the stator coil appearance to obtain the extension lines a, b and c and a', b' and c' and A; 3) by the beta numerical value change, determining whether the interference occurs. By adopting the above technical scheme, the method of the present invention has the advantages of being simple in operation and less in time consumption. According to the present invention, by extracting the main related appearance size of the hydro-generator stator coil to research and analyze, an oblique angle range of the nose end of the stator coil is controlled, and the interference of the stator coil and the end part leading-out wires of the adjacent coils during an assembly process is avoided. The method is clear in design thinking and concise in design principle.
Description
technical field [0001] The invention relates to a method for avoiding the interference of stator coils of a hydraulic turbine generator. Background technique [0002] The shape of the stator coil of the hydroelectric generator is complex, and it is difficult to predict whether it will interfere with the lead-out lines at the end of the adjacent coil during the assembly process in the traditional two-dimensional drawing design stage; generally, it is necessary to establish a three-dimensional geometric model for the coil to This judgment interferes with the problem, which consumes more time, effort and cost. Contents of the invention [0003] The purpose of the present invention is to provide a method for avoiding the interference of the stator coils of the hydro-generator, which can judge whether there is interference or not by simply drawing a graph. [0004] The purpose of the present invention is achieved through such a technical solution, a method for avoiding the int...
