寒冷地区某长距离引水式电站防冰冻设计

Anti-freezing design of a long-distance diversion type hydropower station in cold region

某工程为寒冷地区长距离明渠引水式电站,采取水库蓄冰增温、渠道防冰、前池排冰、金属结构防冰冻等防冰措施,为工程冬季安全运行提供了保障,为同类工程设计提供了参考。

The anti-freezing design of a diversion type hydropower station with long-distance open channel in cold region is described herein, in which the anti-freezing measures such as raising temperature by impounding ice in reservoir, ice-proof of chan- nel, ice-discharge of forebay, freeze-proof of metal structures, etc. are adopted therein, and then not only the safety of its operation in winter is ensured, but a reference is also provided for the similar projects.
