Applications
To ensure continuity and reliability of power supply, automatic reclosing is widely used in every link of the power system. Here are some common applications:
1.Transmission lines: In transmission lines, automatic reclose can quickly restore power supply and reduce the time of outages due to faults. It can detect a faulty line and automatically close it, and then automatically re-open the line when the fault has been rectified.
2.Power distribution system: In the power distribution network, automatic re-closure allows rapid restoration of branch circuits. It can monitor and isolate failed circuits, and restore normal circuits through auto-reset actions.
3.Power equipment: Automatic reclosing is used to protect equipment from overload, short circuit and other faults in power equipment such as generators, transformers, etc. It can disconnect the faulty circuit in time and automatically reclose after the fault has been removed.
4.Industrial automation: Automatic reclosing can improve production line stability and continuity in industrial automation systems. It reacts quickly to power outages and restores power by auto restart to reduce downtime.
