4 S&C Serie 2000 Circuit-Switcher Outdoor Tranmiion (69 kv through 230 kv) GENERAL Interrupter Serie 2000 Circuit-Switcher employ ingle-gap SF 6 puffer-type interrupter deigned to cloe the circuit in 6 cycle, interrupt the circuit in 6 cycle, and maintain rated dielectric trength when open. Thee dual-function interrupter are factory-filled to full preure under controlled condition and then permanently ealed. Field filling i neither neceary nor poible, thu eliminating the rik of contaminating the interrupting medium. Operator The interrupter are driven by a ingle tored-energy mechanim located at ground level in a 48-volt dc, 125-volt dc, or 115-volt 60-hertz operator furnihed with the Circuit-Switcher. Refer to the STANDARD FEATURES table on page 6, and alo Figure 15 and 17. Thi operator include the following feature: Trip and cloe puh button located inide operator encloure. Manual trip lever, for tripping interrupter in the event control voltage ha been lot. Manual charging handle, for opening diconnect after interrupter have been manually tripped open in the event control voltage ha been lot. Charged and dicharged indicator for tored-energy mechanim. Non-reet electric operation counter. Eight nonadjutable ingle-pole double-throw auxiliary-witch contact which follow the interrupter. Weatherproof, dutproof encloure. Decoupling mechanim which allow decoupling and locking of diconnect-blade power train in the open poition, permitting operational checkout of interrupter, tored-energy mechanim, and relaying equipment without cloing the high-voltage circuit. Two individually adjutable auxiliary-witch contact which follow the diconnect-blade power train and operator when coupled, operator only when decoupled. The mechanim in the operator ha an intantaneou trip-free capability: hould the Serie 2000 Circuit- Switcher be inadvertently cloed into a fault ened by Model 2010 With Horizontal Interrupter and Vertical-Break Power-Operated Diconnect uer-furnihed relaying, the mechanim will trip immediately. To accomplih trip-free operation, the mechanim utilize two pring aemblie: one for cloing, one for opening. Both pring are charged by the operator motor before the Serie 2000 Circuit-Switcher can be cloed. Recharging time after a trip operation i approximately 5 econd for Circuit-Switcher rated 69 kv through 138 kv, and approximately 10 econd for Circuit-Switcher rated 161 kv and 230 kv. Power Train The operator directly drive the interrupter open and cloed through a imple high-peed power train leading from the top of the operator, through a horizontal interphae linkage encloed in a teel-heathed box-type bae, to reciprocating-action inulated operating rod which pa through the center of inulating upport column. A tranfer linkage at the top of each inulating upport column convert the vertical reciprocating motion of the operating rod into horizontal reciprocating motion, to drive the interrupter. The operator alo drive the diconnect open and cloed through a low-peed power train which rotate the inulating upport column. The diconnect on model rated 69 kv through 138 kv i capable of opening and cloing without heitation under ³ ₄-inch ice formation. The diconnect on model rated 161 kv and 230 kv i capable of opening without heitation under ³ ₄-inch ice formation and of cloing without heitation under ¹ ₂-inch ice formation. A decoupling mechanim allow decoupling and locking of the diconnect-blade power train in the open poition, permitting operational checkout of the interrupter, the tored-energy mechanim, and the relaying equipment without cloing the high-voltage circuit. Permanently lubricated bearing are ued throughout both the high-peed and low-peed power train. The inulating upport column are filled with a lubricated dielectric filler which prevent contamination from affecting the dielectric integrity of the column or the inulated operating rod. An aerator i utilized at the upper end of each inulating upport column to eliminate water being pumped-in due to preure differential caued by temperature cycling. Page 4 of 26
