METHOD OF HIGH-VOLTAGE BREAKERS CHARACTERISTICS CONTROL AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC G01R31/327 

FIELD: electrical engineering.

SUBSTANCE: method of oil high-voltage breakers (HVB) characteristics control with shunting resistors is executed in accelerated manner without opening of breaker tank and drain of transformer oil and includes synchronous multi-channel digital registration in modes of HVB connection and disconnection by means of electrical values oscillograms, which are proportional to the rate of movement and travel of movable parts of all HVB poles, and also oscillograms of electrical values that are obtained by means of conversion of breaker poles active resistances values with automatic division of oscillograms into several intervals. It allows to simultaneously determine diversity of operation in modes of all poles contacts closing and opening in time as well as in movement of breaker movable parts, to determine speed and travel of breaker movable parts.

EFFECT: device for control of oil high-voltage breakers with shunting resistors provides determination of breaker contact system operation diversity synchronously to the speed of movement and travel of movable contacts in any conditions of environment.
