摘要

对实验数据进行了分析,以确定防止真空灭弧内闭合Cu-Cr触点在0.5s至4s内通过20kA (r.m.s)时焊接所需的闭合触点力。将表明,如果这些闭合触点在电流通过期间具有多个接触区域以及触点体的加热,则数据可以解释。讨论了在短路电流通过时要求保持闭合的真空断路器中所使用的真空断流器的分析意义。

The contact force to prevent large area, closed, vacuum interrupter contacts from welding when passing high fault currents of up to 4 seconds duration
An analysis is performed on data from an experiment to determine the closed contact force required to prevent the welding of closed, Cu-Cr contacts inside a vacuum interrupter passing 20kA (r.m.s) from 0.5s to 4s. It will be shown that the data can be explained if these closed contacts have more than one region of contact together with the heating of the contact's body during the passage of the current. The implication of this analysis for vacuum interrupters used in vacuum circuit breakers when required to stay closed during the passage of short circuit currents is discussed.
