750kV交流输变电工程设备的国产化

Localization of 750kV AC Transmission and Distribution Engineering Devices

文章介绍了750 kV输变电设备国产化的意义、必要性和可行性。对国家电网公司第1个750 kV输变电示范工程中,变压器、电抗器、开关等主要输变电设备的国内制造商依托国家重点工程,在技术引进、产品研发等方面所做的工作和取得的成果做了较为全面的论述。并介绍了国家电网公司在后续750 kV工程中推动开关设备国产化的情况。最后简要地说明了750 kV输变电设备国产化对特高压设备研制、开发的影响。

The paper introduces the meanings, necessity and feasibility of localization of 750 kV transmission and distribution devices. It also illustrates the 1^st 750 kV transmissiou and distribution demonstration project of the State Grid Corporation of China, including the transformers, electric reactor, switches and other main equipment manufactured by the domestic manufacturers, relying on the key projects of the nation to carry out technical import and development of products as a whole. The authors describe in the paper the conditions for localization of switching device in the following 750 kV projects and influence of localization of 750 kV equipment on study and development of EHV equipment briefly.
