What is the function of Ring Main Unit?

The Ring Main Unit has the most basic function of breaking the integrated operational amplifier and solving the electric isolation. In this case, it expands to disconnect other floating buttons such as AC current, electromagnetic energy collection signal, and remote control detection.

Secondly, the meaning of Ring Main Unit is that all electromagnetic energy from the power station to the transmission and transformation to the power supply system is not an independent route, so if one stage is out of order, an integrated op amp will not work. Up. It is like a piece of Internet. To transmit electricity from A to G, a ring network cabinet like BCDEF is required. Even if a certain Ring Main Unit fails, or a certain route fails, or a certain route is maintained and protected, Carry out power transmission and transformation from other routes to further improve the reliability and credibility of power transmission and transformation.
