With the development of society, the electricity security is required to be more by people, HVCB burdens the dual-control and protection in electric system, whose performance relates to the operation of electric system . mechanic parameter is one of indispensable parameter in analyzing the performance of breaker. The comprehensive characteristic tester of high-voltage switch , namely, the mechanic characteristic tester, is according to the latest version of < high-voltage AC circuit breaker> GB1984-2003 as design model, referring to the third part of PRC’s power industry standards <Genera technical specifications for high voltage test equipment>, and designing based on DL/T846.3-2004, which inspect various grades of voltages in high-voltage circuit breaker’s mechanic dynamic characteristic parameters about oil lack, oil excess, vacuum and sulfur hexafluoride, to provide convenience to many kinds of breakers.
