Abstract
PURPOSE: To accomplish trip control of a breaker by constant breaking characteristic, free from any time lag set in the breaking circuit through self-retention of identifictation for respective trouble detection relays by means of a self- retaineing circuit.
CONSTITUTION: It is the same with the conventional controller that in response to internal troubles developing in two circuits of No.1 and 2 transmission lines 1 and 2, protective relays 1R and 2R starts working. But, the transmitssion line protective relay 1R and 2R respectively provided with self-retaining auxiliary relays 1X and 2X so that self-retention may be formed through normally open contacts 1CB2 and 2CB2 of breakers 1CB and 2CB in the respective circuits. With such an arrangement, the breaking characteistic can be maintained at the same level both in No.1 and 2 lines as when under the self-retention. If there is no difference in the working time between the auxiliary relays 1X and 2X, the breaking characteristic can be maintained at the same level, thus made free from difference in the settling time of the time relays 1T and 2T.
