Aimed at the difficulty of calculating moulded case circuit-breaker contact breaking speed, a quantitative arithmetic method was proposed.
针对塑壳断路器触头分断速度计算难的问题，提出了一种定量计算触头分断速度的方法。

This requirement has brought about the development of breaker operating mechanisms that are not only high-speed opening, but are also high-speed reclosing.
这种要求已促使研制出具有不仅能快速分闸而且也能快速重合闸的断路器操动机构。

If the capsule's quality can't meet the demand, the excessive rapid release speed of the breaker would lead to the fracture fluid viscosity premature descending and inducing the failure of work.
