When a *2kV overhead distribution line (Line T) is connected to a branch line or if an internal user fault occurs, improper adjustment of the timing between the line switch protection and the substation outlet switch protection can cause the substation outlet switch to trip. If the fault is permanent, any attempt by the substation to restore power will fail, leading to a power outage along the entire *2kV distribution line in a medium-voltage user community.
Installing an outdoor junction
breaker at the T-junction or at the customer's boundary (the
responsibility demarcation point) can prevent this issue. This
breaker will localize faults, such as overcurrent, short
circuits, or single-phase grounding, ensuring that faults in
specific areas do not result in outages across the entire
distribution line.
Â
When the user boundary is clearly defined and faults are automatically isolated, users in unaffected areas can continue to receive power without interruption. The ZW****2F outdoor high-voltage intelligent demarcation vacuum circuit breaker (watchdog) is suitable for *2kV feeder overhead lines to prevent unnecessary disconnections of unaffected lines. This approach reduces the scope of power failures, minimizes outage durations, and protects the main network for safe operation.
The breaker offers fault detection,
protection control, and communication functions, enabling
automatic disconnection of single-phase ground faults and
isolation of phase-to-phase short circuits. It is installed at
the responsibility demarcation point, where the user connects to
the *2kV distribution line, and can also be applied at branch
line connections that meet installation requirements.
