Dual Power Source Automatic Cut - in Equipment Gas Insulated Metal - clad Switchgear
Overview:
In order to meet the increasing demand for reliability of power supply , we have developed a new generation of dual power supply Automatic Cut - in Equipment . It can make intelligent judgement according to the state and load state of the main power supply, and automatically switch it so that realize the reconfiguration of distribution network and improve the reliability of power supply.
Product features:
1. Reliable mechanical design ensures that the two power supply will not be closed, and has very high safety and reliability.
2. It can automatically select the main power supply and standby power supply, and automatically switch to the standby power supply when the main power supply is out of power or under pressure.
3. The state of the main power supply and the load condition can be judged intelligently, and the best switching time can be selected to switch the power supply to improve the stability of the system operation.
4.The PT sampling power interface can be reserved in the gas tank, and the power supply of the operation mechanism can be powered by two sides of the PT.
5. fully insulated and fully enclosed structure, high safety and complete operation.
