漫湾电厂一期工程总装机容量1250MW,自1993年6月30日第一台机组发电以来,至1996年6月30日止累计发电量114亿千瓦时,1995年发电量占系统年发电量的1/3,为缓解云南电力紧张局面和经济发展做出了突出的贡献。 三年来,由于设计、制造、安装遗留的缺陷以及产品性能差等原因,机电设备存在一些隐患,严重威胁着机组的安全稳定运行。为此,我厂对原设备进行了技术改造,引进了一些先进技术和设备,取得了较大的经济效益。 一、新投产主、辅设备存在的主要问题
The total installed capacity of the first phase of Manwan Power Plant is 1,250 MW. Since the first unit was produced on June 30, 1993, the accumulated power generation amounted to 11.4 billion kWh as of June 30, 1996. The amount of electricity generated in 1995 accounted for the annual power generation of the system. 1/3 of them made outstanding contributions to alleviating tension and economic development in Yunnan. In the past three years, due to the defects in design, manufacturing, installation, and poor product performance, electromechanical equipment has some hidden dangers, which seriously threatens the safe and stable operation of the unit. For this reason, our factory has carried on the technological transformation to the original equipment, introduced some advanced technology and the equipment, has obtained the bigger economic efficiency.
