DETERMINATION OF MOVEMENT CURVE OF CIRCUIT BREAKER DISCONNECTOR Russian patent published in 2016 - IPC G05B15/00 H01H11/00 

FIELD: electricity.

SUBSTANCE: system determining the movement curve of the contacts of the circuit breaker disconnector includes memory for the storage of set information relating to movement distances of the circuit breaker contacts of an HV circuit, and a processor determining the movement curve, that graphically represents the position over time for at least one of the following operations for the circuit breaker contacts: closing, opening or their combination, depending on one or several movement distances of the stored information about the movement distances, and one or several time values corresponding to the state changes of the breakers between the closed and open states. Therein the breakers are secured to the contacts such that they switch from the closed to open state upon the contacts movement between the closed and opened positions.

EFFECT: assurance of reliable monitoring of the breakers operability without the use of the contacts movement transmitter.
