Embodiment 1
[0022] Embodiment 1: The linear solidification process of the stator bar of the large-capacity air-cooled turbogenerator includes the following steps:
[0023] 1). According to the requirements of the drawing, put the insulation between the rows along the length of the slot, that is, the length of the stator core slot, and use 1 / 3 of the release tape to wrap, that is, overlap 1 / 3 of the bandwidth when wrapping the tape;
[0024] 2). Put the stator bar into the linear curing mold;
[0025] 3). Pressurize 2N / mm on the wide surface of the stator bar 2 , Narrow surface pressure 3N / mm 2 ;
[0026] 4). Use a heating plate to heat the stator bar, start heating from room temperature, and perform the following operations according to the temperature value;
[0027] 5). When the temperature is 90°C, keep warm for 5 minutes, and pressurize the wide surface of the wire rod to 8N / mm 2 , pressurize the narrow side of the wire rod to 9N / mm 2 ;
[0028] 6). When the temperature is 130°C...
Embodiment 2
[0037] Embodiment 2: Different from Embodiment 1:
[0038] 3). Pressurize 3N / mm on the wide surface of the stator bar 2 , Narrow surface pressure 4N / mm 2 ;
[0039] 5). When the temperature is 90°C, keep warm for 5 minutes, and pressurize the wide surface of the wire rod to 9N / mm 2 , to pressurize the narrow side of the wire rod to 10N / mm 2 ;
[0040] 6). When the temperature is 130°C, pressurize the wide surface of the wire rod to 11N / mm 2 , pressurize the narrow side of the wire rod to 13.5N / mm 2 ;
[0041] The rest are the same and will not be repeated here.
Embodiment 3
[0042] Embodiment 3: Different from Embodiment 1:
[0043] 3). Pressurize 4N / mm on the wide surface of the stator bar 2 , Narrow surface pressure 5N / mm 2 ;
[0044] 5). When the temperature is 90°C, keep warm for 5 minutes, and pressurize the wide surface of the wire rod by 10N / mm 2 , pressurize the narrow side of the wire rod to 11N / mm 2 ;
[0045] 6). When the temperature is 130°C, pressurize the wide surface of the wire rod to 12N / mm 2 , pressurize the narrow side of the wire rod to 14N / mm 2 ;
[0046] The rest are the same and will not be repeated here.
