Cutoto-Mounted Reclose

Ang TripSaver II Cutout-Mounted Recloser nagpadayon sa mga utilities nga mapabulag sa pagpahimulos sa overhead lateral circuit protection sa 15 kV ug 25 kV pinaagi sa pagkombinado sa labing maayo nga bahin sa fuse-saving ug fuse-blowing. Ang mga reclosers sa TripSaver II nagpanatili sa kuryente sa mas daghan pa nga mga customer ug nagsugyot sa costly truck rolls para sa utilities. Kini nga estratehiya nagdugang og additional reclosing device as close as possible sa pinaghugnoan sa problema, mao nga ang tanging mga customer sa faulted lateral lang ang naapektuhan. Ang kuryente mahimo mosubay sa automatic sa temporary faults, ania ang giwasay sa sustained outages ug namaliksi sa momentary outages sa feeders pinaagi sa "blinking" tanging mga customer sa faulted lateral. Ang utilities makita ang immediate reduction sa frequency sa sustained outages sa ilang sistema ug dramatic improvement sa reliability scores.

Punong Katangian sa Cutout-Mounted Reclosers

1. Automatic Distinguishes & Handles Temporary/Permanent Faults, Enabling "Self-Healing"

• Kinahanglan ang mga faults (e.g., short circuits, overloads) nga mogrow sa line, quick interrupt sa fault current (response time in milliseconds) aron mapigilan ang pagkalat sa fault.

• Para sa higit sa 80% sa temporary faults sa power systems (e.g., lightning strikes, momentary tree contact, brief bird-caused short circuits), automatic attempt ~3 reclosure cycles (configurable count). Kon ang fault clear, ang kuryente mopauli bisan walay manual intervention.

• Kon ang fault permanent (e.g., line breakage, equipment damage), automatic "lock out" (forming a visible circuit gap) human sa failed reclosures. Kini completely isolate ang faulty section aron mapigilan ang pagapekto sa tanang line, samtang nakatabang sa maintenance personnel nga mapabilis ang paglocate sa fault point.

2. Directly Adapts to Existing Lines, No Additional Infrastructure for Installation

• Walay modification sa existing lines ang gikinahanglan. Kini mahimo direkta i-install sa fuse base sa distribution lines (replacing traditional fuses), utilizing the original line's installation space and wiring.

• Compact in size, walay complex wiring o independent cabinets. On-site installation kinahanglan lamang standard electrical tools ug mahimo mopasabot sa 1-2 maintenance staff. Kini support mainstream low-voltage distribution line voltage levels (e.g., 15kV/25kV).

3. Significantly Improves Power Supply Reliability, Reducing Outage Impact

• Namaliksi ang unnecessary outage duration: Temporary faults resolved automatically within seconds, eliminating the need to wait for manual repairs (e.g., avoiding prolonged blackouts across an area after a lightning strike).

• Namaliksi ang outage frequency: By isolating permanent faults, tanging ang branch line sa fault ang naapektuhan (dili ang entire main line), minimizing the outage scope.

• Industry data shows it can reduce the distribution line's SAIDI (System Average Interruption Duration Index) by 80% and SAIFI (System Average Interruption Frequency Index) by 60% especially effective for fault-prone branch lines.

4. Safe Arc Extinction + Visual Fault Identification, Reducing Maintenance Risks

• Adopts vacuum interrupter technology: Arc extinction occurs internally during fault interruption, eliminating sparks and high-temperature debris (common with traditional fuses) to prevent fires or burns.

• After locking out due to permanent faults, it forms a visible mechanical gap (e.g., the physical gap after contact disconnection). Maintenance personnel can judge the fault status visually without live testing, reducing electric shock risks.

5. Low-Cost Maintenance, Reducing Labor & Resource Consumption

• No frequent on-site replacements: Traditional fuses require staff to travel to the site for replacement after faults. This device handles temporary faults automatically, and only one on-site reset is needed for permanent faults—reducing over 90% of "unnecessary maintenance trips".

• No additional energy consumption: It does not require batteries or external power, relying on the line’s own electricity to power the internal microprocessor—lowering long-term operating costs (e.g., a device from a leading brand can recover its cost after just 4 avoided maintenance trips).

6. Supports Smart Grid Integration, Compatible with Remote Monitoring

• Equipped with remote communication interfaces (supporting mainstream protocols DNP3), it can upload real-time device status (e.g., "open/closed", "locked-out", "fault type") to monitoring platforms.

• Maintenance personnel can remotely configure parameters (e.g., reclosure count, interrupting current threshold, reclosure interval) via the backend—no on-site adjustments required. This is particularly suitable for maintaining lines in remote areas
