OUTDOOR INTELLIGENT HIGH VOLTAGE DUAL
POWER SUPPLY SWITCHING DEVICE

Overview
ZW10- Ⅱ -12G / 630-20 type high voltage dual power supply switching device (hereinafter referred to as device) is composed of a high voltage vacuum
circuit breaker and an intelligent controller. It is used in a dual-channel 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 is switched to another normal power supply to ensure the continuity of power supply. At the
same time, it has short-circuit and over-current protection interlocking functions, which effectively avoids unnecessary power supply impact when the
load fails. When the common power supply fails and the power fails, the switching device can complete the switching with the backup power supply
to ensure reliability and safety. It can also 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-
switching and self-resetting dual-channel power supply automatic switching product with novel design, perfect performance, safe and reliable, high
degree of automation and wide range of use. The design of the product guarantees the complete isolation of the two high-voltage power supplies, and
at the same time uses perfect and reliable mechanical and electrical interlocking, so it has very high safety and reliability. This product is suitable for dual
power users who have high requirements on power supply reliability and safety, as the control and protection settings of the dual power supply system.
The products are widely used in oilfield, mining, metallurgy, chemical industry, railway, communication, machinery and other 10kV distribution lines, and
industrial and mining enterprises 10kV lines.
