Introduction of mechanical tests on intelligent high voltage switchgear

With the development of the Smart Grid, the research on the intelligent high voltage switchgear, as the basis of the Smart Grid, has developed a growing concern. Nowadays, the application of online monitoring technique and equipment makes the high voltage switchgear become an intelligent one. However, because of lacking the test standard, the research on the test method and test equipment is far more behind. It has become an obstacle for the research-and-development and operation of the intelligent high voltage switchgear. This paper is inspired during the construction project of “National Intelligent Electrical Equipment Quality Supervision and Inspection Center”. By analyzing the function and the structure of intelligent high voltage switchgear, and combining with the existing standards of high voltage switchgear, an equipment is developed for the mechanical characteristic testing equipment of the intelligent high voltage switchgear. The equipment can be used for both the intelligent and the traditional high voltage switchgears. The study described in this paper, can help the test center and manufacturing enterprises to establish the test conditions, to improve the reliability and competitiveness of the product design, and to provide strong support for optimizing the development of intelligent switches. It fills the blank of mechanical performance verification tests for intelligent high voltage switchgear. It is worth to popularize.
