Dual power automatic conversion
◆Adopts double-row composite contacts, cross-connection mechanism, micro-motor pre-energy storage and< br/> Microelectronic control technology basically achieves zero arc flashover (no arc extinguishing cover)
◆Adopt reliable mechanical interlocking and electrical interlocking technology
◆Adopt zero-crossing technology
◆ With obvious on-off position indication and padlock function, it can reliably realize the isolation between the power supply and the load. High reliability, with a service life of more than 10 times
◆Mechatronic design, switch conversion is accurate, flexible, reliable, good electromagnetic compatibility, and strong anti-interference ability , no external interference, high automation program
◆ Fully automatic type does not require any external control components, beautiful appearance, small size, light weight. The logic control board manages the motor directly installed in the switch with different logic. The action of the gearbox is operated to ensure the position of the switch.
The motor is a polychloroprene rubber insulated humid-heat type motor equipped with a safety device that will trip when the humidity exceeds ℃ and the over-current condition occurs.
It will automatically start working after the fault disappears. The reversible reduction gear adopts spur gear.
① Cut off the circuit breakers of the mains power supply (including the circuit breakers of the control cabinet in the power distribution room and the mains power supply breaker of the dual power supply switching box), open the double-throw anti-reverse switch to the side of the self-prepared power supply, and keep the dual The self-contained power supply circuit breaker in the power switching box is disconnected.
② Start the backup power supply (diesel generator set). When the standby unit is operating normally, sequentially close the generator air switch and circuit breakers in the self-supplied power supply control cabinet.
③Close each backup power circuit breaker in the power switching box one by one to deliver power to each load.
④ During the operation of the backup power supply, the operating personnel on duty are not allowed to leave the generator set, and the voltage, plant frequency, etc. should be adjusted in time according to the changes in the load, and any abnormalities should be dealt with in a timely manner.
When the mains power supply is restored, the power conversion work should be done in time, the backup power supply should be cut off, and the mains power supply should be restored.
