HORIZONTALLY TURNING DISCONNECTING SWITCH |
摘要 |
FIELD: high-voltage circuit-opening devices for no-current switching of electric circuits and producing visible open circuit in air. SUBSTANCE: disconnecting switch has frame with one fixed and one turning insulators and lever-type control gear; control-gear operating mechanism; current-carrying system with contact blades; current collector with contact lead for connecting power conductors. Current-carrying system is built up of two parallel moving contact blades interconnected through current-carrying and fixing bushings and fixed phase contact. Ends of blades embracing phase contact are engageable with the latter; spring ensuring contact pressure is mounted on rod inside post which is placed between blades and fixed on upper blade; current collector that has current lead for connecting power conductors is hinged on mentioned fixing bushing by means of U-shaped bracket provided with holes and connected to current- carrying bushing and upper blade through flexible conductor. EFFECT: improved performance characteristics, reduced size and mass, improved reliability and safety in operation. 4 cl, 6 dwg
