The new ABB AutoLink electronic sectionalizer provides
an economical solution for sectionalizing overhead
distribution lines, thus improving system reliability and
providing users with unique flexibil ity. Both the number
of counts and the actuation current can be set and reset
on the product to adjust for specific coordination needs.
Additional ly, unlike other products in the marketplace, the
AutoLink does not require any tools for resetting. These
combined features translate into reduced inventory, labor
expenses, and number of power outages.
Description
The device consists of a fuseholder base identical to the
one used for simple fused cutouts. This base is fitted with a
tube that houses an electronic circuit, which discriminates
permanent from temporary faults, thus granting immunity to
symmetrical and asymmetrical inrush currents. The electronic
circuit also sets the mechanical opening of the sectionalizer if
the fault current is determined to be permanent or continuous.
The device’s resetting module is found under the tube’s upper
contact cap. Through this module, the operator can manually
configure and reconfigure the sectionalizer’s actuating currentand number of cycles to obtain the desired combination for
system protection.
When placed in combination with an upstream recloser (or
recloser switch), the AutoLink installed on a downstream
service connection counts the operations and, once it reaches
the preset count (1 to 4 opening operations of the recloser),
it cuts the circuit while the circuit is being opened by the
recloser. The circuit is restored by manually resetting (with no
tools) the mechanical device.
OperationIf a temporary fault occurs, the upstream recloser equipment
opens and the AutoLink sectionalizer counts one opening
operation. Then the recloser closes. Because the fault is
temporary, it is cleared so that both the downstream equip-
ment and the AutoLink are connected and the circuit stays
in operation. After 30 seconds, the AutoLink resets and the
count is completed.
If a permanent fault occurs, the continuous reclosing opera-
tions do not clear the fault. The AutoLink counts the opening
operations and, upon reaching the set count, opens the line
with the permanent fault.
Application
The ABB AutoLink coordinates perfectly with medium voltage
distribution networks. Due to new technology introduced in
the AutoLink sectionalizer, the actuating current and counts of
any single equipment can be reset to the different configura-
tions of the network as many times as necessary, allowing aproper coordination in current and future protection combina-
tions. The use of the AutoLink in branch and service connec-
tions, instead of the fused sectionalizer, allows better coordi-
nation in the event of faults, thus decreasing both operating
costs and the number of power outages.
