POWER CIRCUIT BREAKER AND SWITCHING PANEL WITH POWER CIRCUIT BREAKER Russian patent published in 2014 - IPC H01H33/56 H02B13/45 

FIELD: electricity.

SUBSTANCE: multi-phase, in particular, three-phase, high-voltage power circuit breaker in a metal body with gas insulation comprises one pole (11, 12, 28) of a chamber of the power circuit breaker for each phase, which are jointly placed into one common body (21) of the power circuit breaker, and at least two connecting taps for each phase. The body (21) of the circuit breaker has such number of face ends of its chambers, which corresponds to the number of poles (11, 12, 28) of the circuit breaker chambers, in which poles (11, 12, 28) of the circuit breaker chambers are installed. Open face ends of chambers (29, 29a; 30, 30a; 31, 31a) are closed by means of dome-shaped covers (22, 23) so that gas connection between separate chambers (29, 29a; …) is provided via connection spaces formed by covers (22, 23). Also a switching panel is described with a power circuit breaker.

EFFECT: increased compactness of a circuit breaker in respect to required space and place, and also amount of insulating gas.
