Zhejiang Bosida Electric Co., Ltd.

The r/3-type high-voltage dual power mutual switching device (hereinafter referred to as the device) is composed of a high vacuum circuit breaker and an intelligent controller. It is suitable for dual-channel power supply systems with cross-hertz, rated voltage of kV, and rated current up to 3. When one power supply fails or is under-voltage, it will automatically switch to the other normal power supply to reliably ensure the continuity of power supply. At the same time, it has short circuit and overcurrent protection interlocking functions, which effectively avoids unnecessary re-power supply shock when the load fails. When a common power supply fails and a power outage occurs, the switching device can complete automatic switching with the backup power supply to ensure reliability and safety. It can also selectively switch between the two power supplies according to the needs of the load, which is especially suitable for applications where power outages are not allowed. In important occasions, as an important electrical control device to ensure continuous power supply, it is a new generation of mutually switching and self-restoring dual-circuit power automatic switching products with novel design, perfect performance, safety and reliability, high degree of automation and wide range of use. The product is designed in It ensures the complete isolation of two high-voltage power supplies and adopts complete and reliable mechanical and electrical interlocking, so it has very high safety and reliability. This product is suitable for dual-power power users who have high requirements for power supply reliability and safety. , as the control and protection setting of the dual power supply system. Products are widely used in oil fields, mining, metallurgy, chemical industry, railways, communications, machinery and other distribution lines, industrial and mining enterprise lines
