400A Copper Electrical tulip jaw contact 4 Pins For Vacuum Circuit
Breaker
The "vacuum circuit breaker" is named because its arc extinguishing
medium and the insulating medium in the contact gap after arc
extinguishing are high vacuum; It has the advantages of small size,
light weight, frequent operation, and no overhauling of Arc
extinguishing. It is widely used in distribution networks. The
vacuum circuit breaker is an indoor distribution device in the
3-10kV and 50Hz three-phase AC system, which can be used for the
protection and control of electrical equipment in industrial and
mining enterprises, power plants, and substations. It is especially
suitable for use places that require no oily, less overhaul, and
frequent operation. The circuit breakers can be configured in the
middle cabinet, double cabinet, and fixed cabinet as control and
protection of high-voltage electrical equipment.
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.
