Embodiment Construction
[0030]The invention relates to a manufacturing method of a vacuum pressure impregnated stator wire rod of an air-cooled water turbine generator. The VPI stator wire rod is composed of a straight part and two ends.
[0031] straight line (such as figure 1 or image 3 shown), including: wire narrow surface insulation pad (1), transposition insulation layer (2), wire composed of magnet wire (3), insulation between wire rows (5), main insulation layer of wire bar (6) , low-resistance anti-corona layer (7), inner shielding layer (8);
[0032] end (eg figure 2 or Figure 4 (shown) includes: wire narrow surface insulating pads (1), two or four rows of wires composed of electromagnetic wires (3), insulation between wire rows (5), main insulation layer of wire rods (6), anti-corona at the end layer(9);
[0033] Wire rod bonding structure (such as Figure 1 ~ Figure 4 (shown) is: wire narrow surface insulating gasket (1) not only fills the transposition pits on the narrow surface...
