This kind of intelligent AC contactor has features of intelligentization, controllability, benefiting from combining technologies such as electrical equipment, power electronics, microcomputers and sensors. It becomes a reality to break contacts without arc or with less arc by controlling the intelligent AC contactor, particularly by using zero-current interrupt control technology, leading to energy savings, low operating noise, high electrical span, and high operating frequency. The functions and performance of the AC contactor can be substantially improved and to meet the need of smart grid development. Key technologies such as the accuracy and stability of zero-current interrupt of three-phase contactor are also discussed in this paper. We expect this type of intelligent AC contactor to find broad applicability in power distribution systems, especially smart power grids.","PeriodicalId":379448,"journal":{"name":"2011 1st International Conference on Electric Power Equipment - Switching Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114383427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is thus necessary to clarify the breakdown mechanism in a vacuum. It is well-known that these characteristics are influenced by the electrode material and its surface condition[1][2], but the breakdown mechanism has not been clarified. This paper presents measurements of breakdown characteristics and observations of a cross-section after electron beam irradiation. The results are compared with those for no electron beam irradiation. It is thus shown that the breakdown voltage of a CuCr electrode after electron beam irradiation is higher than that for no electron beam irradiation. This is because a fine Cr layer is formed on the electrode surface.","PeriodicalId":379448,"journal":{"name":"2011 1st International Conference on Electric Power Equipment - Switching Technology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134634606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Between two contact-tips, there is a point of contact that is a very small area. Therefore, a current between a fixed-tip and operative-tip flows through a very small area, which is the point of contact. Then, due to current concentration, magnetic flux density between two contact-tips produces the electromagnetic repulsion force. Because repulsion force can improve interrupting ability of MCCB, it is important to analyze the electromagnetic repulsion force, which occurs between two contacts. To analyze electromagnetic repulsion force, the Finite Element Method (hereafter FEM) is adapted. Further, through the interrupting test, correlation between repulsion force and interrupting ability was confirmed. We calculated the electromagnetic repulsion force via five models and tested interrupting ability via one model.","PeriodicalId":379448,"journal":{"name":"2011 1st International Conference on Electric Power Equipment - Switching Technology","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126875424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the multi-objective particle swarm algorithm was proposed and used in the global optimization of cylinder linear induction motor according to its characteristic. Secondly, the mathematical model of multi-objective optimization algorithm was established based on the grain of subgroup algorithm, and the programs were compiled by using the Matlab engineering calculation tool, at the same time the visual interface was developed. Finally, the results indicated that the multi-objective optimization design is obviously better than the single optimization design. The thrust are increased, the structure and size of motor are also reduced. So it can increase the usability of the C-LIM drive mechanism and provide the basis for the design of miniaturization of circuit breaker operating mechanism.","PeriodicalId":379448,"journal":{"name":"2011 1st International Conference on Electric Power Equipment - Switching Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121913014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
