The working principle of the ATS control cabinet is to monitor the status of two power supplies, usually including main power supply (such as mains power) and backup power supply (such as generator). When the main power supply is normal, the ATS cabinet connects the load to the main power supply; once the main power supply is interrupted or fails, the ATS cabinet automatically switches the load to the backup power supply to ensure the continuity and reliability of power supply. When the main power supply returns to normal, the ATS cabinet will automatically switch the load back to the main power supply and stop the backup power supply.
The main components of the ATS cabinet include control components and circuit breakers, which can achieve fast and smooth power conversion and avoid power interruption caused by power switching. This kind of equipment is particularly important in power systems with strict requirements on power interruption, such as critical facilities such as hospitals and data centers, because these places require uninterrupted power supply to ensure normal operation and safety.
The ATS cabinet is simple in design and easy to operate, and can realize unattended automatic switching function. Depending on the application requirements, ATS cabinets can also be equipped with manual operation options to allow for human intervention in special circumstances. In addition, to ensure safe and reliable operation, ATS cabinets are usually equipped with short-circuit protection devices and other safety features.
