Product Overview:
An auto recloser maintains grid reliability by automatically isolating transient faults caused by environmental factors like lightning or debris.
If the fault clears quickly, the device restores power within milliseconds through a programmed reclosing sequence. If the fault persists after 0 to 3 attempts

Key Structural Features of the LR32 Auto Recloser:
Vacuum Circuit Breaker:
The core component is a vacuum circuit breaker mounted on a pole.
Power Distribution Terminal:
Equipped with a DLXCLS51 power distribution terminal for enhanced control and monitoring.
Power Voltage Transformer:
Includes a power voltage transformer for accurate voltage measurement and control.
Modular Design:
The recloser features a modular design, with components connected via outdoor control cables and hermetically sealed aviation plugs, ensuring easy installation and maintenance.
Stainless Steel Housing:
The housing is made of high-quality stainless steel, providing rust resistance for long-term outdoor operation.
Permanent Magnet Mechanism:
Utilizes a reliable three-phase monostable permanent magnet mechanism with a mechanical life of up to 10,000 operations.
Automatic recloser is widely used in every link of power system to ensure the continuity and reliability of power supply. Here are some common applications:
1.Transmission lines: In transmission lines, automatic reclosing can quickly restore power supply and reduce the time of outage caused by failure. It can detect and automatically close faulty lines, and automatically re-close them when the fault is eliminated.
2.Power distribution system: In the power distribution system, automatic reclosing enables rapid recovery of branch circuits. It can monitor and isolate faulty circuits, and restore normal circuits through automatic reclosing operations.
3.Power equipment: In power equipment, such as generators, transformers, etc., automatic reclosing is used to protect equipment from overload, short circuit and other faults. It can cut off the fault circuit in time, and automatically re-close after the fault is removed.
4.Industrial automation: In industrial automation systems, automatic reclosing can improve the stability and continuity of the production line. It responds quickly to power system failures and restores power through automatic reclosing operation, reducing downtime.
Vacuum interrupter technology is safer, eco-friendly, and requires almost zero maintenance compared to older oil-based recloser models.

The LR32 series integrates with SCADA systems, allowing remote monitoring and remote control of the unit from a central station.
An automatic recloser is intelligent and reusable, unlike drop-out fuses that require manual replacement, and the auto recloser significantly improves operator safety.
The LR32 series is designed for outdoor installation with weather-resistant materials and an IP65 ingress protection rating to handle harsh environmental conditions.
An auto recloser automatically restores power after temporary faults (like lightning or tree branches) and “locks out” if the fault is permanent, ensuring grid protection.
