Automatic Circuit Recloser F-ACR
Automatic Circuit Reclosers (ACRs) are outdoor intelligent switch applied in the filed of distribution automation, usually mounted on outgoing line side of substation, tie points of ring network, trunk line of distribution grid, or at the head of important feeder lines, with short-circuit current breaking and making ability, completed with feeder terminal unit (FTU), which can realize multiple reclosing function. When a short-circuit fault occurs on the line, Automatic Circuit Recloser implements cycling operation according to the sequence and time interval. When a permanent fault occurs, after implementing preset cycling operation sequence, Automatic Circuit Recloser is keep opening and block to close to isolate the faulted section. When the fault is removed, a manual reset is needed to release blocking status and implement close operation. When a transient fault occurs, the subsequent opening and closing operations are terminated in the cyclic opening and closing operation, regardless of which reclosing is successful, and initial setting status is restored after a certain delay time. Our company latest development xx series Automatic Circuit Recloser s, cover 15KV, 27KV, 38KV voltage level, reach 1200A maximum rated current, meet IEC62271-111 and IEEE C37.60 international standards.
