Don't mislead the people upstairs, okay? Power distribution cabinets and switch cabinets are the same thing. Switchgear is divided into high voltage and low voltage. There are ring network cabinets, central cabinets, GG 1A and so on. There are also many kinds of ring network cabinets. Next, I will introduce that the ring network of the lower ring network and the ring network cabinet refers to the ring distribution network, that is, the power supply trunk line forms a closed ring, and the power supply supplies power to this ring trunk line, and then distributes power from the trunk line to the outside through the high-voltage switch. This has the advantage that each distribution branch can obtain power from its left and right trunk lines. When the left trunk line fails, it will continue to get power from the right trunk line, and when the right trunk line fails, it will continue to get power from the left trunk line. In this way, although the total power supply is unidirectional, it will get benefits similar to bidirectional power supply from each distribution branch, thus improving the reliability of power supply. The so-called "ring network cabinet" means that each distribution branch is equipped with a switch cabinet (outlet switch cabinet), and the bus of this switch cabinet is also a part of the ring trunk line. That is to say, the ring trunk line is composed of buses of various outlet cabinets connected together. Each outlet cabinet is called "ring network cabinet". In fact, it is not meaningful to take out a ring network cabinet alone. These ring network cabinets are not large, so the high-voltage switch of ring network cabinets generally adopts a simple high-voltage load switch with a high-voltage fuse, rather than a circuit breaker with complex structure. In other words, the high voltage switch in the ring network cabinet is generally a load switch. The ring network cabinet uses the load switch to operate the normal current and the fuse to cut off the short-circuit current, and the two are combined to replace the circuit breaker. Of course, this can only be limited to a certain capacity. This kind of switchgear can also be used in the distribution system without ring network structure, so with the wide application of this kind of switchgear, "ring network switchgear" jumped out of the category of ring network distribution, generally referring to high-voltage switchgear with load switch as the main switch.
