TZW10-12 XDG, high voltage dual power supply mutual investment device (hereinafter referred to as the device), consists of a high voltage vacuum circuit breaker and intelligent control part. It is suitable for dual power supply system with 50Hz, rated voltage of 12KV and rated current up to 630A. When one power supply is out of power or under voltage, it will automatically switch to another normal power supply to ensure the continuity of power supply. At the same time, it has the functions of protection and interlocking such as short circuit and over current, which effectively avoids unnecessary re-power supply shock when the load failure happens. When the common power supply fails, the switching device can complete the automatic switching with the standby power supply to ensure reliability and safety. It is also possible to switch between two power sources according to the needs of the load. It is especially suitable for important places where power failure is not allowed, as an important electrical control device to ensure continuous power supply. It is a new generation of self-returning dual-channel power supply automatic switching products with novel design, perfect performance, safety and reliability, high degree of automation and wide application range. The product is designed to ensure complete isolation of the two high-voltage power supplies, while using a complete and reliable mechanical and electrical chain, so it has a very high degree of safety and reliability.
This product is widely used in oil field, mine, metallurgy, chemical, railway, communications, machinery and other 10KV distribution lines, industrial and mining enterprises 10KV lines.
