发电机

Due to the cooling-water tube diameter of the generator is too small, the velocity of cooling-water is also too low, if we only use the travelling period difference of one emmission and reception, the propagation time will be too small to test. Then, we select ultrasonic circulation method as our concrete plan.

由于发电机冷却水引水管的管径小，冷却水的水流速度低，利用单次发射和接收的时间差检测时，传播时间差极其微小，故作者首次提出利用声循环法来检测大型汽轮发电机定子线棒冷却水流速。

Guangxi Yantan turbine diameter 8m 90s in the 20th century in operation, mainly due to the hydraulic design and manufacturing quality Runner and other reasons, put into operation a serious vibration, cracks, vibration tube into the door crack, power generation Floor Vibration machine layer. 10 years of annual repair cracks, cavitation, multiple blade line has been restored can not be guaranteed, for the more radical change in this situation, has on one desktop PC upgrades, replacement of the old wheel, replaced by a Taiwan new designs, new technology a new wheel, troubled years of generating station floor floor vibration problems are basically solved.

广西岩滩水电站直径达8m的水轮机在20世纪90年代投入运行，主要是由于水力设计和分瓣转轮制造质量等原因，投入运行后振动严重，裂纹产生，尾水管进入门振裂，发电机层楼板振动。10年来年年修补裂纹、空蚀、多次修复后叶片型线已无法保证，为较彻底的改变这种状况，已对其中一台机进行升级改造，更换了老转轮，代之以一台新设计、采用新工艺的新转轮，困扰电站多年的发电机层楼板振动问题得到基本解决。

In the generator, first epoxy covering the coil winding instead of iron core of laminated silicon steel is used to fix the coils in the three-phase synchronous alternator. Since the generator does not induce the cogging torque effect because of the coreless design, it can rotate easily under the breeze situation.

在发电机方面，首先吾等使用的三相同步交流发电机，以环氧树脂包覆线圈，取代矽钢片叠成之铁心来固定线圈，所以不具槽隙转矩效应，因此能在扭力极低的情况下轻易转动。

In the same year that Edison's steam-driven generators were inaugurated, a waterwheel-driven generator was installed in Appleton, Wisconsin.
