KYN28 indoor metal-clad switchgear is a complete power distribution device for 3.6~24kV,3-phase AC50/60Hz,single-bus and single-bus sectionalized system. It is mainly used for power transmission of middle/small generators in power plants; power receiving, transmission for substations in power distribution and power system of factories, mines and enterprises, and starting of large high-voltage motor, etc.,so as to control, protect and monitor the system. The switchgear meets IEC298,GB3906-91.In addition to be used with domestic VS1 vacuum circuit breaker, it can also be used with VD4 from ABB, 3AH5 from Siemens domestic ZN65A, and VB2 from GE, etc.,it is truly a power distribution device with good performance.
In order to meet the requirement for wall mounting and front-end maintenance, the switchgear is equipped with a special current transformer, so that the operator can maintain and inspect it in front of the cubicle.
The SF6 insulated switchgear is suitable for middle voltage power distribution system with a rated voltage of 12kV. It could be used as RMUs in a power supply network, fault isolating switches and sectionalizing switches. If equipped with distribution automation devices (FTU/DTU) and communication devices, the SF6 insulated switchgear could communicate with the control center, measure the cable voltage, current, etc, and monitor the working status of switches.
BKRM6- 40.5 series of ring main unit is SF6 gas- insulated metal common tank enclosed switchgear, consisting of load break switch unit, load break switch fuse combination electrical unit, vacuum circuit breaker unit, and the incoming line unit of bus. It adopts a range of advanced technologies and materials, with excellent electrical and mechanical properties, less affected by environment and climate, in small size, easy to install easy to operate, with no need of maintenance, and can be flexibly combined. Its clear and intuitive design ensures simple and direct operation, the feeder's connection capacity is large, suitable for a variety of wiring systems.
Besides,we can replace the SF6 gas with nitrogen(N2 gas) that it will become a environment protection green gas insulated switchgear. The green gas insulated switchgear safer and environmentally friendly more than SF6 GIS and it will replacing SF6 GIS in the future.
KYN28-12 removable AC metal-clad switchgear (short for panel as below) is a new product. It will be a substitute for old fashioned metal-enclosed switchgear, such as KYN-12, JYN-12, GFC-12, etc.
The panel applies to 3.6~12kV 3 phase AC 50Hz network for receiving and distributing power energy and also for control, monitor and protection. It accords with standard of IEC62271-200, IEC60694, GB3906.
The newly introduced and developed large current and high breaking switchgear can also be used as a high- voltage generator export.

Application:
HV test shielding room (faraday cage) are Widely used in power cable, transformer, transformer switch, transformer substation and other High voltage levels of partial discharge test or impulse test.
For HV testing shielding room, as a HV test place, it should has good electromagnetic
shielding condition. And its electromagnetic compatibility always is of great importance.
Firstly, it should restrict electromagnetic wave into inside shielding room caused by
discharge when making HV test to weakening interfere to outside, especially on
electronic and communication system. Secondly, it should prevent outer
electromagnetic wave intruding into shielding room to cause measurement error of
partial discharge and wireless. Thirdly, it should reduces open circuit voltage and
closed current to restrain common-mode interference so that to avoid equipment
damage and to improve accuracy of impulse measurement.
For GIS HV test shielding room, design area is 500 m2ï¼?Length 25mã??Width 20m).
From provided information , we find that steel structure have been completed
already with one set of 20T crane indoor, crane supporting corbel also completed, the
height is 17.9m from ground to upper part of corbel. Main door height 13m,width 10m,
locates at downward of the west side, the door open direction towards to north .
According to ILJIN drawing, three side of structure column has already, but western
structure column still missing yet. however, as the main door will be located in this side,
the western side also should have steel structure , and this structure position still should
be unified considered with main door installation. We will be able to submit suggested
design diagram with position & size of this structure column for reference. in order to
save construction cost, the construction engineering will be carried out by ILJIN
team.
