Abstract

AN INSULATING SWITCHING APPARATUS EMPLOYING A GAS-TIGHT SEALED ENVELOPE WHICH ENCLOSES THEREIN A CLOSED-TYPE VACUUM CIRCUIT BREAKER CONNECTED TO AN ELECTRIC LOAD AND A PAIR OF OPEN-TYPE LOAD-BREAK SWITCHES RESPECTIVELY CONNECTED TO A PAIR OF OPEN-TYPE LOAD-BREAK SWITCHES RESPECTIVELY CONNECTED TO A POWER RECEIVING CIRCUIT AND IS FILLED WITH ELECTRICALLY INSULATING GASES, THE SWITCHES BEING ARRANGED ADJACENT TO EACH OTHER, COMPRISES A GAS-FLOW GUIDE FOR INDUCING A DESIGNATED FLOW OF ARCED GASES PRODUCED WHEN AT LEAST ONE OF THE OPEN-TYPE SWITCHES IS CUT OFF TO BLOCK CURRENT FLOW THERETHROUGH SO AS TO PREVENT UNDERSIRABLE ARCED GAS FLOW TOWARDS THE CLOSED-TYPE SWITCH. THE GAS-TIGHT SEALED ENVELOPE INCLUDES A PAIR OF U-SHAPED MEMBERS WELDED TO EACH OTHER IN A GAS-TIGHT FASHION TO PROVIDE A GAS-TIGHT SEALED HEXAHEDRAL TANK, SUCH THAT THE U-SHAPED SECTION OF ONE U-SHAPED MEMBER IS PERPENDICULAR TO THE U-SHAPED SECTION OF THE U-SHAPED MEMBER.(FIG 2)
