KYN61-40.5 Armoured removable AC metal-enclosed
switchgearProduct description: Suitable for three-phase AC 50Hz,
35KV single-bus and single-bus section power systems, it is mainly
used in power plants, substations, and industrial and mining
enterprises, as well as in high-rise building power distribution
for accepting and distributing power, and for controlling,
protecting, and monitoring circuits, and can also be used in
frequently operated places. The product design meets the
requirements of GB3906, IEC60298, DL404 and other standards, and
has a complete "five-proof" function.service condition:1. Altitude:
no more than 2000 meters;2. Ambient temperature: the upper
limit +40°C; the lower limit -15°C;3. Relative humidity: the daily
average value no more than 95%, and the monthly average value
no more than 90%;4. Earthquake intensity: no more than 8
degrees.5. There is no risk of fire and explosion, and there is no
serious pollution such as severe vibration and chemical
corrosion.Product Features:Adopting heat-shrinkable insulating
materials and epoxy coated insulation technology, optimizing
electrode shape, compacting cabinet structure and reducing occupied
area.The cabinet body of the switch cabinet is made of high-quality
cold-rolled steel plate or flated aluminum-zinc plate processed by
CNC sheet metal processing, and is connected by high-strength bolt
nuts and rivet nuts.It can be equipped with domestic TEP-40.5 type
3TH (ZN85-40.5) VD4 vacuum circuit breaker and SF1, SF2, HD4 type
sulfur hexafluoride circuit breaker to meet the needs of different
users.Each functional compartment of the switch cabinet is
separated by metal partitions and has an independent pressure
relief channel.Circuit breaker, grounding switch, etc. can be
operated with the switch cabinet door closed, which can realize
door-closing operation.The switch cabinet is highly adaptable, with
main connection schemes exceeding 198, to meet the needs of
different users.There is a mechanical interlocking device to
prevent misoperation between hand wheel, circuit breaker, grounding
switch, and rear cabinet door, with complete "five protections"
functions and safe and reliable.Equipment Parameters
