Longitudinal rotary type function composite type vacuum isolation circuit breakers
2006
The present invention relates to a vertical screw-functional complex vacuum isolation breaker, three-phase pole, and the actuator trolley frame assembly, longitudinally aligned phase pole by a rotatable integrally attached stringers, the pole vacuum interrupter chamber is occluded by an epoxy resin as a composite body of insulating material (solid) seal, may be coupled with the main circuit of the electric pole at both ends of the fixed contact, stringers hinged in handcart frame, a drive is provided in the stringer vacuum interrupter moving contact link, the operating device containing a circuit breaker, disconnector operating means and mechanical interlock integrated actuator means and control means mounted on the front of the trolley frame it can drive link means rectilinearly movable contact driven vacuum interrupter breaking and closing a circuit, and can make a positive pole three-phase, reverse rotation shuttle 90 °, both ends of the driving electrical connection contacts head or isolating the circuit. Products with a compact, easy to maintain, run the operating safety, etc., especially suitable for use with the switchgear.
