Overview of dual power switch backup power supply

To be precise, if the dual-power switch backup power supply is always in the energized state, we can call it a hot backup, which is usually used for more important users. Another thing is that when the backup power supply uses the engine to delay power generation, then the dual power switch at this time will play its due role. It will immediately cut off the mains circuit and also generate power for the generator. Good access preparation.

Overview of dual power switch backup power supply

Especially when the dual power switch cuts off the mains circuit, it is very important. First, it can effectively prevent the phenomenon of self-generation from being reversed to the mains grid, and then it can also prevent the formation of self-generation when the mains power comes on suddenly. The unsynchronized grid connection situation caused both parties to trip. The working principle of the dual power switch is that when both sides are in a state of power, but only one can be turned on, that is to say, this automatic conversion can be divided into two ways.

The simple mode is that when both of them are in the state of no electricity, the double power switch will turn on which side comes first. If there is a phenomenon of electricity, you need to see which system has a faster response speed. Therefore, at this time, there will always be one that turns on first and cuts off the other startup circuit at the same time.

There is also the working principle of the dual power switch that uses the switching action of Three-Phase three-wire and three-phase four-wire. First of all, its configured controller will detect the voltage on the two circuits at the same time. When it exceeds the rated value by 110% (can be When the power supply voltage is adjusted, it can be judged that this situation is overvoltage, and when it is less than 80% of the rated value (adjustable), it will be judged as under (or loss) voltage phenomenon, so the micro-control device feedbacks the circuit The above-mentioned data detection results are logically judged.

That is to say, the processing result will use the delay (adjustable) circuit to drive the corresponding instruction, and send the opening and closing instructions to the voltage operating mechanism. At the same time, the above detection results can be displayed on the LCD on the dual power switch intelligent controller panel. The Screen can clearly see the data Display. If the backup power supply fails at this time, the alarm will immediately alert the relevant staff to repair the backup power supply as soon as possible, and will also provide relevant cause clues so that it can be in a short period of time. Repair the faulty circuit within the time and ensure that the dual power switch can supply power normally. One thing to note is that if you want to see if the backup power supply has power, you must first see whether the power supply uses an uninterruptible power supply. If the power source is all intermittent, even if you use a dual power switch or any other switch, the power supply cannot be guaranteed. normal.
