The difference between switch cabinet and ring network cabinet

Ring network cabinet can form a closed ring power supply trunk, power supply to the ring trunk, from the trunk and then all the way through the high voltage switch to the external distribution. The advantage of this is that each distribution branch can both take power from its left trunk, and can take power from its right trunk. Broke down when the left side of the main line, and it is from the right side of the main power supply will continue, and when there is something wrong with the main line, on the right side it is from the left side of the main power supply, will continue in this way, although the single power supply is the total power, but from each distribution branch was similar to the double road power supply, so as to improve the reliability of power supply.

Generally speaking, you can regard ring network cabinet as a distribution room of power supply bureau! Let your home is not only a power supply cabinet, several lines into a ring network, to achieve two or more lines. Such a line has a problem, there will be no power outage, it is necessary for urban residents and industrial and mining enterprises.

Switchgear is a kind of electrical equipment. Switch cabinet outside first into the cabinet main control switch, and then into the sub-control switch, each branch according to its needs to set. Such as instrumentation, automatic control, motor magnetic switch, all kinds of AC contactor, some also set high voltage chamber and low voltage chamber switch cabinet, with high voltage bus, such as power plants, and some also set low cycle load reduction for the main equipment. The main function is to open and close, control and protect electric equipment in the process of power generation, transmission, distribution and electric energy conversion in the power system. The main components in the switch cabinet are circuit breakers, isolation switches, load switches, operating mechanisms, transformers and various protective devices.

The so-called "ring network cabinet" is each distribution branch set a switch cabinet (outgoing switch cabinet), the switch cabinet bus is also a part of the ring trunk. That is to say, the ring trunk is connected by the busbar of each outlet cabinet. Each outlet cabinet is called "ring network cabinet". In fact, it is impossible to see the meaning of "ring network" by taking out a ring network cabinet alone. The high voltage switches in ring cabinet are generally load switches. Ring cabinets use a combination of load switches to operate normal current and fuses to cut off short-circuit current to replace circuit breakers, of course only within a certain capacity. This switch cabinet can also be used in the distribution system of non-ring network structure, so with the wide application of this switch cabinet, "ring network cabinet" jumped out of the ring network distribution category and generally refers to the high voltage switch cabinet with load switch as the main switch.
