(一) 改造挖潜势在必行雅安地区太平二级水电站投产于50年代初期。发电机是德国西门子公司40年代的产品,装机容量300kW,水轮机紧固件为英制。经过四十年的运行,发电机绝缘老化,调速器、水轮机磨损严重;拦河坝基脚淘空,坝顶被泥石撞击成缺口;厂房防洪墙基础被冲刷、淘空,发电机地坪产生横向裂缝。总之,电站严重老化,汛期安全尤其令人担心,必须彻底整治改造。1989年,公司决定对其进行改建。由于本站上游建有库容272.5万m。的黄龙水库和峡口电站,能起调节作用,故改造后装机扩大为2×400kW,且无淹没搬迁问题。
(A) the transformation of potential Tapping Potential Ya’an Taiping II hydropower station put into operation in the early 1950s. The generator is a product of the 1940s from Germany’s Siemens with an installed capacity of 300kW and turbine fasteners in imperial. After 40 years of operation, the generator insulation aging, governor, turbine wear and tear; barrage foot barren, the dam crest was hit into a gap; plant flood wall foundation was washed, Amoy sky, the generator floor Horizontal cracks. In short, serious aging power plants, flood safety is particularly worrying, we must completely rehabilitate. In 1989, the company decided to rebuild it. Due to the upstream site has a capacity of 2727000 m. Huanglong Reservoir and Xiakou Power Station can play a regulating role, so the installed capacity after the renovation expanded to 2 × 400kW, and no flooding relocation problem.
