Aiming at the problem of owing to power grid scale and single unit generating power capacity continuous expanding,causing power grid short circuit current augmenting,By using fast vacuum breaker technology,fast switches the current-limiting reactor on to limit short circuit current deeply,reduces power grid short circuit current. Through the wide application of power grid intermediate voltage system and verification of 330 kV line installation,the results show that using fast vacuum breaker technology to limit short circuit current of power grid can avoid larger operating loss bringing of the conventional current limiting technology,realize the aim of portable structure, low cost,reliable operation for current limiting device of power grid.
