Description ：
With the development of society, people have higher and higher requirements for power supply reliability. In many cases, two power supplies are used to ensure the reliability of power supply, which requires a product to switch reliably between two power supplies. The intelligent dual power automatic conversion device produced by our company is mainly composed of a high-voltage vacuum circuit breaker with electric dual isolation and a dual power intelligent backup self-input controller. Applied to AC 50HZ, rated voltage 12KV, rated current up to 1250A dual power supply system, when one power failure or undervoltage occurs, the isolation switch automatically switches to the other, the whole process automatically switches to the other normal power supply. Reliable guarantee of continuity of power supply.
The controller has a variety of protection functions such as short circuit, three-stage overcurrent, single-phase ground, undervoltage, reclosing and prepaid, which effectively avoids unnecessary re-supply shock when the load fails. When the common power supply fails, the switching device can automatically switch with the standby power supply to ensure reliability and safety. It is especially suitable for important places where power is not allowed, as an important electrical control device to ensure continuous power supply, it is a self-throwing self-restoring dual power automatic switching device matching with high voltage vacuum circuit breaker. The products are widely used in 10kV distribution lines in oil fields and mines, and 10kV lines in industrial and mining enterprises to ensure real-time power supply of important loads. It has the characteristics of small footprint, small investment, convenient debugging and maintenance, and is an ideal switchgear for realizing power supply automation.

What is a high voltage dual power switch?
A: The high-voltage dual power switch is a device used to automatically switch between two high-voltage power supplies. When one power supply fails (such as power failure, abnormal voltage, etc.), it can quickly switch the load to another normal power supply to ensure the continuity of power supply.
Where is it mainly used?
A: In hospitals, data centers, large factories and other places where continuity of power supply is highly required. For example, during hospital surgery, a sudden power outage may endanger the patient's life, and the use of high-voltage dual power switch can avoid this situation.
How fast does it switch?
A: Generally speaking, the switching time can reach the millisecond level, which can minimize the time of load power failure and avoid damage to the equipment.
