Abstract (en)
[origin: EP0424281A1] The invention relates to a device for operating the divided-pole circuit-breaker, having an operating mechanism (26) coupled to an rotary intermediate shaft (54) of a transmission device (52) arranged inside a beam (20) formed into a compartment. At the base of each pole (12, 14, 16) is arranged an individual housing (38) enclosing a first crank (40) connected to the actuating rod (32) of the movable contact, and carried by a semi-shaft (68) passing tightly through the housing (38). A connecting-rod/crank system (72, 74, 76) is arranged between the intermediate shaft (54) and the semi-shaft (68) of each pole. This arrangement makes it possible easily to modify the separation of the poles as a function of the voltage of application of the circuit-breaker. <IMAGE>
