FERREED CONTACT |
摘要 |
electrical engineering. SUBSTANCE: ferreed contact with breaking contact pair in which overlapping centers of normally open and normally closed pairs are offset over longitudinal axis of cylinder and three contact members are not overlapping has optimal angle between loose end of normally closed pair stop brought in contact with movable member ranging within 0°<alpha°<=15° and initial value of normally open pair gap in absence of external magnetic field is found from equation where X1 is initial gap of normally open pair; C2 is stiffness of normally closed pair stop; a is amount of normally closed pair overlapping; alpha° is angle between movable contact member surface and loose end of normally closed pair stop; l1 is length of movable contact member ensuring change-over operations; C1 is stiffness of movable contact member; l2 is offset of overlapping centers of normally open and normally closed pairs over longitudinal axis of cylinder. EFFECT: enhanced reliability of ferreed contact. 2 cl, 4 dwg
