摘要

This article provides insights into the latest practices of Siemens Energy eco-friendly Blue switchgear products. Furthermore, operational experience to date globally and in China will be presented. Some research, development and additional tests have been done to ensure that products are of high quality, efficiency and reliability. Clean air specification is given, and different product development status is summarized. Some of the research on X-ray radiation and its protection, verifying the integrity of vacuum interrupters, special applications are explained in detail. Additional reliability tests, like tightness tests with helium vs. SF₆, sea freight with rated filling pressure, vibration tests and seismic tests, are also presented and discussed. In the end, high expectations are provided for vacuum switching technology to be applicable to high voltage levels above 145kV.
