Measures to prevent clearance and ventilation notch groove corona high voltage motor
The gap and the ventilation groove to prevent corona notch high-voltage motor measures are as follows:
1 coil groove is used in the low resistance and the anti corona layer;
2 slot using semiconductor paint (Pen Huotu);
All 3 pad are semiconductor glass panel;
4 the gap should be less than 0.3-0.5mm, or the filling of semiconductor material, tightly, to prevent vibration after loosening;
5 to increase the stability of the anti halo layer and the groove wall contact point.
Process points are:
1 brushing process, the brush before the paint stirring uniform;
2 resistivity to be stable;
3 the anti corona layer and the insulation bond is good.
