HEAVY-CURRENT DISCONNECTING SWITCH

FIELD: indoor disconnecting switches. ^ SUBSTANCE: proposed heavy-current disconnecting switch has rectangular frame that mounts electric insulators. Disposed on the latter are two core-mounted coaxial current-carrying contacts which are insulated from one another and from disconnecting switch. Current-carrying contacts have similar number of contact members symmetrically disposed over circumference. Ends of contact members facing each other are separated by disconnecting-switch discharge gap. This discharge gap is electrically shorted out in ON-position of switch by spring-loaded sections longitudinally disposed on core over circumference. Sections and contact members are made of pins. Ends of contact members free from working contacts are overhanging from current-carrying contact leads. Limiting stops are installed for opposite ends of contact members to prevent their crosswise movement from longitudinal axis of disconnecting switch; segments are installed for crosswise movement toward longitudinal axis of disconnecting switch. ^ EFFECT: minimized inherent power loss as well as mass and size of heavy-current disconnecting switch. ^ 13 cl, 9 dwg
