Model meaning
ZW10-1I-12G/630-20 high-voltage dual power switching device (hereinafter referred to as the device) is composed of a high-voltage vacuum circuit breaker and an intelligent controller.
Application
In the dual power supply system with AC 50 Hz, rated voltage 12kV, and rated current up to 630A, when one power supply fails or is under voltage, it switches to another normal power supply to reliably ensure the continuity of power supply. At the same time, it has protection interlocking functions such as short circuit and overcurrent, which effectively avoids unnecessary power supply shocks when the load fails. When the common power supply fails, the switching device can complete the switching with the backup power supply to ensure reliability and safety. It is also possible to select and switch between the 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 self-switching and self-replicating dual-channel power supply automatic switching product with novel design, perfect performance, safety and reliability, high degree of automation and wide range of use. The design of the product ensures the isolation of two high-voltage power supplies, and at the same time adopts perfect and reliable mechanical and electrical interlocking, so it has very high safety and reliability. This product is suitable for dual power supply users who have high requirements on power supply reliability and safety, as a control and protection setting for dual power supply systems.
Products are widely used in oil field, mining, metallurgy, chemical industry, railway, communication, machinery and other 10kV distribution lines.
