Different uses, Zhongzhigui is commonly known as KYN28 cabinet, handcart type high voltage switchgear, generally used to protect back-end Transformers, or other high pressure load. The ring net cabinet is mainly used for the distribution of high voltage power supply. The cabinet is mainly used for high pressure load protection. Ring net cabinet with air insulation, and a fully closed filling cabinet? In both cases, the air insulation is connected to a system using a common SF6 load switch through a copper row, while a fully closed filling tank has a special connection device in addition to the power inlet and outlet line, and the cabinet is connected to the cabinet in a complete gas chamber filled with SF6 gases.The use of the cabinet is mainly 10KV system electrical distribution room, circuit breaker and metering unit can be removed, for handcart type structure, line and feed protection is more complete, rated current is 630 ~ 3150A; (1) The use of the cabinet is mainly 10KV system power distribution room, circuit breaker and metering unit can be removed, for the handcart structure, the line and feed protection is more complete, the rated current is generally 630 ~ 3150A, the ring network cabinet is generally used in the medium pressure secondary distribution or box change, the advantage is a fixed structure small volume, most of the vacuum or 6 gas insulation, but the rated 12 circuit breaker is less than the use of the general maintenance of the load, there is gas production of the switch. Mainly used in systems below 1000 KVA Transformers. The ring net ark originally serves as the ring net connection, this is the ring net ark name reason. Because it is the use of the ring network, it only needs to be divided rated current, short circuit current division does not need it(do not understand please consider carefully). So the loop cabinet just needs a load switch, not a fuse.
