Dual power interconnection device

The high-voltage dual power interconnection device (hereinafter referred to as the device) consists of two parts: a high-voltage vacuum circuit breaker and an intelligent controller. Applied in a dual power supply system with AC frequency of 50 Hz, rated voltage of 12KV, and rated current up to 630A, it automatically switches to the other normal power supply when one power supply experiences a power outage or undervoltage, ensuring reliable continuity of power supply. At the same time, it has protection interlock functions such as short circuit and overcurrent, effectively avoiding unnecessary power supply shock in case of load failure. In the event of a power outage due to a malfunction in the common power supply, the switching device can automatically switch to the backup power supply to ensure reliability and safety. It is also possible to switch between two power sources according to the needs of the load. Especially suitable for important places where power outages are not allowed, as an important electrical control device to ensure continuous power supply. Design a novel, high-performance, safe, reliable, highly automated, and widely applicable dual power automatic switching product for the new generation. The product is designed to ensure complete isolation of two high-voltage power sources, and adopts a complete and reliable mechanical and electrical interlock, thus having very high safety and reliability. This product is suitable for dual power users who have high requirements for power supply reliability and safety, as a control and protection setting for dual power supply systems.
