MZZ (II) -12/T630-20 outdoor AC high voltage automatic recloser (hereinafter referred to as "recloser") is an outdoor high voltage switchgear with three-phase AC 50Hz. It is mainly used as a 10kV side outgoing switch and 10kV line protection switch in urban and rural substations, which can automatically monitor the operation status of transmission lines, accurately judge instantaneous or permanent faults, and eliminate more than 95% of instantaneous faults. This recloser is a self-contained control and protection function that can automatically perform disconnection and reclosing operations in the AC line according to the predetermined disconnection and reclosing sequence, and then automatically reset or lock afterwards. When used in conjunction with sectionalizers, it can achieve distribution automation without relying on additional control systems. This system minimizes the range and time of power outages to the greatest extent possible, and is also equipped with standard RS232, 485 communication interfaces, and four remote functions, providing strong support for the implementation of comprehensive automation in the power system.

Structural features:
1. The microcomputer control device is equipped with a set of 20 batteries, and the battery capacity can support 50 hours of operation after a power outage.
2. The battery charging adopts electronic PT, AC220V, or CT charging, which is safe and reliable.
3. The device has the function of on-site remote control switch on/off operation, with a remote control distance of 30 meters, and on-site operators do not have the difficulty of climbing power poles.
4. Provide protection setting management function, users can freely modify the tripping current, and the setting value is flexible.
