ZW10-II-12G outdoor intelligent high-voltage dual-power switching device|Hongtuo Transformer Co., Ltd

summary:

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 double-circuit power supply system with AC 50 Hz, rated voltage 12 kV and rated current up to 630A, when one circuit of power supply is powered off or under voltage, switch to another circuit of normal power supply to reliably ensure the continuity of power supply. At the same time, it has protection interlock functions such as short circuit and overcurrent, which effectively avoids unnecessary power supply impact in case of load failure. In case of failure and power failure of the common power supply, the switching device can complete the switching with the standby power supply to ensure reliability and safety. You can also select and switch between two power supplies 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 design, perfect performance, safe and reliable, highly automated, and widely used automatic switching product of the self-switching and self-recovery dual power supply. The product is designed to ensure the isolation of two high-voltage power supplies, and adopts perfect and reliable mechanical and electrical interlocking, so it has very high safety and reliability. This product is applicable to dual-power power users with high requirements for power supply reliability and safety, as the control and protection setting of dual-power supply system.

The products are widely used in 10kV power distribution lines in oil fields, mines, metallurgy, chemical industry, railways, communications, machinery, etc.
