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 GB1984-2003 as design model, referring to
the third part of PRC�s power industry standards , 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.
