Basic Info.

Product Overview
KYN28A-12 indoor AC high-voltage metal removable switchgear is a complete indoor power distribution device with three-phase AC 50Hz, rated voltage 12kV and working current up to 4000A. It is applicable to power plants, substations, industrial and mining enterprises, etc. for receiving and distributing electric energy. It can control, protect and monitor the circuit, and can be used in places with frequent operation.
Executive Standards
GB3906	<3.6-40.5kV AC Metal Switchgear and Control Equipment>
GB/T11022	<Common technical requirements for high-voltage switchgear and control equipment standards>
IEC298	<AC metal switchgear and control equipment with rated voltage above 1kV to 72.5kV>
DL/T404	<Technical Conditions for Ordering Indoor AC High Voltage Switchgear>
Product Features
1	Safe and reliable "five prevention" interlocking device can effectively prevent: 1.Prevent false opening and closing of circuit breaker 2.Prevent pushing and pulling circuit breaker handcart with load 3.Prevent closing the circuit breaker when the grounding switch is closed 4.Prevent false closing of grounding switch during live operation 5.Prevention of entering the live space by mistake
2	Optional ZN63A (VS1), VD4, ZN21, 3AH and VEP vacuum circuit breakers, VC7 vacuum contactor load switch and disconnector, etc.
3	It can be divided into circuit breaker handcart, voltage transformer handcart, metering handcart, isolation handcart, etc. according to the purpose, handcart with the same purpose has good interchangeability.
4	The circuit breaker room and cable room can be equipped with heaters to prevent condensation and corrosion.
5	The enclosure protection level of the switch cabinet reaches IP4X, and the protection level between compartments and when the door of the circuit breaker room is o 5 pened is IP2X.
Product Mix
The product is composed ofacabinet and awithdrawable part(handcart). The cabinet structure is made of aluminum-coated zinc plate. The circuit breaker room(handcartroom), main bus room, cable roomand relay instrument room are separated by metal partitions, and all metal structures are reliably grounded. The main bus room and circuit breaker room areequipped with independent pressure release channels.

Structural Features
Thestructure of the switchgear is shownin the right figure. All-metal modular assembly stnucture.The cabinet body is made ofimported aluminum-coated zincplate with strong corrosion resistance,without surface treatment. It is processed by high-precision equipment, and adopts advanced multiple flanging technology.The connection is connected with rivet nuts and high strength bolts, with high accuracy, light weight and good strength. Thes witchgear can be equipped with QCEI series,VD4series, ZN65series and othervacuum circuit breakers produced by the company, with wide adaptabiity and strong interchangeability. The handcartis equipped with working position, test position and positioning and display device at each position,which is safe and reliable. The cable room can be equipped with up to 9 single-core cables, and the equipment has reliable mechanical and electrical nterlocking devices, fully meetingthe "five prevention" requirements. Each room isequipped with pressure relief channel to ensure personal safety of operators.
