High Voltage Switchgear and RMU is any difference between the ring finger ring distribution network, namely the supply mains to form a closed loop, power supply to the ring mains supply, then all the way from the trunk all the way to distribution out through the high-voltage switch Such advantage is that each distribution branch either to the left with its trunk to take power, they can take it on the right by the mains supply. When the left side of the trunk out of trouble, Xiping low voltage switch cabinet principle, it to continue to receive power from the right side of the trunk, and when the right side of the trunk out of trouble, it will continue to receive power from the left side of the trunk, so since, although the overall power supply is a single power supply, but for each distribution branch but get benefits similar to the dual power supply, thereby improving the reliability of power supply. The so-called "RMU" is to set up a branch in each distribution switchgear (switchgear outlet), this switchgear bus at the same time is part of the ring main line. That is, the ring mains outlet cabinet by each bus connecting together thereof. Each outlet cabinet called "RMU." In fact single out one can not see the RMU "Ring," the meaning of these RMU is not large, so RMU high voltage switches are typically taken by high voltage switches simple structure with high-voltage fuse breaker without using complicated structure. In other words, RMU in the high-voltage switches are generally load switch. RMU with load switch operating normal current, low voltage switch cabinet Wugang principle, but with the removal of short-circuit current fuse, the two combine to replace the circuit breaker. Of course, This can only be limited to a certain capacity. Such switchgear and distribution systems can be used completely non-ring structure, so with the widespread use of such switchgear, "RMU" jumped out of the ring with and refers to the scope of power load switch the main switch of high voltage switchgear.
