ZW32-12GG/12KV Outdoor Intelligent High Voltage Dual Power Switching Device

>Overview

With the development of society, users have higher and higher requirements for power supply reliability. In many occasions, two power supplies are used to ensure the reliability of the power supply, which requires a product to perform reliable and safe switching between the two power supplies. This kind of demand is developed and designed. The ZW32-12GG dual power automatic conversion device is composed of a single high-voltage vacuum circuit breaker and a double-sided isolation switch. It is used in a dual power supply system with AC 50 Hz, rated voltage 12KV, and rated current up to 1250A. When a power failure or undervoltage occurs in one power supply, the electrical isolation automatically switches to the other 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 electric isolation switching device can complete the automatic 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 an electric dual-circuit power switching device matched with high-voltage vacuum circuit breakers. Novel design, perfect performance, safe and reliable, 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 oil fields and mines, and 10kV lines in industrial and mining enterprises.

>Normal use environment

◆The upper limit of ambient air temperature does not exceed +40C, the lower limit does not exceed -25C, and the average temperature value for 24 hours does not exceed +35°C.

◆The altitude of the installation site is applicable to 3800m.

◆The relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is + 40°C, and it can have a higher humidity at a lower temperature;

When the monthly average lower limit temperature of the wet month is -25C, the average upper limit relative humidity is 90%, and the condensation on the surface of the product due to humidity changes is considered.

◆The pollution level is three.

◆There is no strong vibration and shock in the operating place, no harmful gas that corrodes metal and destroys insulation, no serious dust, no conductive particles and explosive dangerous substances.
