Abstract

PURPOSE: When the A-C power of the stationary type frequency transformer that transforms the direct current in the middle is not obtained due to the power failure, the reactor of the direct current circuit is short circuited and the striking pulse of each transformer is obstructed to prevent the failure of current branching and prevent the accedent of overflowing current when the A-C power is restored.
