How does an outdoor vacuum recloser work?
Normal Operation: The recloser is in the closed position, and the line is supplying power normally. During this time, current flows through the main contacts of the recloser, and the vacuum arc quenching chamber remains in a high-insulation state. The operating mechanism maintains the closed position to ensure stable power transmission.
Fault Detection and Tripping: When a fault such as a short circuit or overload occurs in the line, the current transformer detects the fault current, and the protection device immediately issues a tripping signal. The operating mechanism receives the signal and rapidly drives the main contacts to separate. The vacuum arc quenching chamber instantly extinguishes the arc, cutting off the fault current and protecting the safety of the power system.
Reclosing Operation: After the fault current is interrupted, the recloser automatically performs a reclosing operation after a preset time interval. The operating mechanism re-closes the main contacts to restore power to the line. If the fault still exists, the recloser will detect the fault current again and trip. It will then perform multiple reclosing attempts based on the set number of reclosures and time intervals until the fault is cleared or the maximum number of reclosures is reached.
