MV KYN28C-12 Metal-clad Movable Switchgear - Miniaturization
MV KYN28C-12 metal-clad movable switchgear.
MV KYN28C-12 metal-clad movable switchgear is the modification of MV KYN28A-12 metal-clad movable switchgear,
so it not only has the advantages of MV KYN28A-12 metal-clad
movable switchgear, but it also has other features shown below.
- The cabinet size: width: 650 mm, depth: 1200 mm, height: 2200 mm.
And this kind of switchgear is smaller than other standard
- It is equipped with ZN63K solid sealed polar pole type vacuum
circuit breaker, and insulation performance is perfect. And this
design solves the vacuum circuit breaker environment tolerance
problem and it makes circuit breaker miniaturization and
high-reliability come true.
- The rated current is 1250 A when the width of switchgear is 650 mm.
If the rated current is larger than 1250 A, the width of switchgear
should be larger than 650 mm.
- Both of current transformer and voltage transformer are
manufactured of miniaturization and technical indicators meet
standard requirements. And they can be installed in cabinet body
- Pressure relief cover is designed of heat dissipation function,
which is beneficial to in-time ventilation & heat dissipation.
This design can also prevent dust effectively.
- Small bus-bar terminal and small bus-bar are our patented products,
and their installation and overhaul are simple and convenient.
Normal working conditions:
- Temperature range: -25 °C to +40 °C.
- The maximum daily average relative humidity: 95%.
- The maximum monthly average relative humidity: 90%.
- Altitude1000 m.
- Seismic intensity8 degree.
Note: if the working condition is beyond the normal working conditions,
please contact us before goods ordering.
Special matters needing attention:
The temperature of many regions in our country is high, and
temperature fluctuation is fast, so switchgears are faced with the
risk of condensation running in this kind of environment.
Therefore, there are some matters needing attention in switchgears
- Heaters should be put into operation as early as possible after
switchgears are installed.
- Ensure heaters at running condition all day during switchgears
standing by and running.
MV KYN28-12 intelligent metal-clad switchgear and its main switches
