| Abstract | Due to the principle of extinguishing for SF6 high voltage circuit breaker, the throat will be clogged, and the arc energy will be transferred into the puffer chamber to increase the puffer pressure. That makes the arc energy play an important part in pressure character. Based on the first law of thermodynamics, the law of hydrokinetics and the second law of Newton, the mathematic model of pressure character of SF6 high voltage circuit breaker was built. Applying this method associating T100s test duty the gas pressure characters of the 252 kV SF6 circuit breaker were calculated, the pressure build process were obtained and the influences of interrupted arc on gas pressure character, by comparing with the experimental result, the theoretical model can be modified and recalculated. And the influence of throat structural parameters to the characteristic of pressure was analyzed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
