Double power automatic switching distribution cabinet equipment

The dual power automatic switching device is applicable to the switching between two power supplies (common power supply and standby power supply) with the rated voltage of AC no more than 1000v and DC no more than 1500v and below due to the abnormality of one power supply, so as to ensure the safety and reliability of * * * power supply. Product features

1: Two electrically operated circuit breakers are equipped with electrical interlocking devices and mechanical interlocking devices, which are accurate and reliable when one circuit breaker is used.

2: The device uses a circuit breaker with high breaking capacity, and has overload and short circuit protection.

3: The device can be provided with manual switching and automatic switching. The automatic transfer switch is divided into two forms: automatic switching and automatic recovery and automatic switching and non automatic recovery. During operation, the three-phase voltage of two power supplies (common power supply and standby power supply) shall be tested at the same time. In case of overpressure, undervoltage (including phase loss), power failure and other faults in any phase, the power supply can be switched from the normal power supply side to the normal power supply in a delayed manner and output with * * * power supply without fault.
