Product Overview
With the development of society, users have higher and higher requirements for power supply reliability. Many occasions with two power supply to ensure the reliability of power supply, which requires a product to be reliable and safe switching between the two power supplies, the company's ZW32-12GG type dual power supply standby self-throwing device is to meet this demand development and design.
ZW32-12GG dual power automatic conversion device is composed of two parts: a single high-voltage vacuum circuit breaker and a double-sided isolation switch. It is used in the dual-channel power supply system of AC 50 Hz, rated voltage of 12KV and rated current to 1250A, when one power supply is out of power or undervoltage, the electric isolation will automatically switch to another normal power supply, so as 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 re-power supply impact when the load fails. In the event of a failure of the common power supply, the electric isolation switching device can complete the automatic switching with the standby power supply to ensure reliability and safety. It is also possible to switch between the two power supplies according to the needs of the load. It is especially suitable for important places where power failure is not allowed, and as an important electrical control device to ensure continuous power supply, it is an electric dual-circuit power switching device matched with a high-voltage vacuum circuit breaker. Novel for new design. Perfect performance, safety and reliability, high degree of automation, wide range of use of dual-channel power supply electric automatic switching products.
The products are widely used in 10kV distribution lines in oilfields and mines, and 10kV lines in industrial and mining enterprises.
