Interlock mechanism control equipment with high or medium voltage compactness and improved cost

摘要

Mechanism (Mi) called locking control electrical equipment of high or medium voltage provided with at least one switch, comprising: - a shaft (12) control; - a first element (1, 2, 3) rotating wheel called combined control assembly and opening, integral with the shaft (12) adapted to control and rotate it by a hand lever; - a second rotating element called wheel (4) output / closing mounted free in rotation about the shaft (12) and the control which is fixed a shaft; - two springs (5, 6) of spiral, of which one called spring (5) opening is adapted to open the unit switch distended from a compressed state and the other called spring (6) closing is adapted to close the unit switch distended from a compressed state, each of the inner ends of the opening spring (5) and plugs (6) fixed to the shaft (12) control while the outer end of the spring (5) opening is fixed the mechanism frame and the outer end of the spring (6) closing is fixed to the wheel (4) closing; - locking means lock (8) and opening (7), pivotally mounted between two states, allowing one state lock wheel (4) output / closing and the other of the combined control wheel, Cocking and opening (1, 2, 3) by simultaneous compression of the spring (6) and closing spring (5) opening through the hand lever in rotation in one direction, allowing the other states on the wheel rotation start / end and then the combined control wheel assembly and opening in the opposite direction by successive strains of the closing spring (6) and opening (5); - means (11, 110, 111) coupling between the lever (9) manually and the combined control wheel assembly and opening, joining said coupling means in the thickness (E) of the combined control wheel, Cocking and opening, and designed to provide a decoupling between said wheel (1, 2, 3) and the lever (9) manually to finish the race reinforced.
