狮子滩电站原使用瑞士出产的波纹管档板式示流信号器,由于长期使用后,波纹管发生疲劳损坏,又无合适的备品更换,而且,此信号器电气接点密封欠佳,容易造成误动作(仅1973～1975年,我站3~#机由于该电气接点受潮,造成误停机达10次之多,使该装置无法继续使用。国产SX—50型浮子式示流信号器使用起来也不够理想(磁环的行程偏小)。为此,我们于78年12月～79年3月将4台机组水轮机轴承润滑水示流器改为磁 Lions Beach power station original use of Swiss bellows baffle type flow indicator, due to the long-term use, the bellows fatigue damage, there is no suitable replacement of spare parts, and the signal electrical contact sealing poor, likely to cause malfunction (Only 1973 ~ 1975, I stand 3 ~ # due to damp electrical contacts, resulting in downtime of up to 10 times, so that the device can not continue to use domestic SX-50-type float-type annunciator is not enough to use Ideal (magnetic stroke is too small) .To this end, we December 78 ~ March 79 will be four sets of turbine bearing water flow indicator to magnetic
