Product Description

++++General
FLBS an indoor high-voltage SF6 load switch, an switchgear with the rated voltage of 12kV/24kV, adopted with SF6 gas as an arc-extinguishing and insulation medium, including the three contactors for switching-on and switching-off and to-ground, and is characteristic in its small volume, its convenient installation and operation and its the great adaptability with surroundings.
FLBS of an indoor high-voltage SF6 load switch and FLBS of SF6 load switch plus fuse combination can function to protect and control the electric equipments for power supply and transformer substations especially being suitable for ring net cabinet, cable branch cabinet and distribution switching substation.
FLBS of an indoor high-voltage SF6 load switch and FLBS load switch plus fuse combination are complied with the standards of GB3804-1990, IEC60256-1,1997, GB16926, IEC60420 etc..

++++Installation, Maintenance & Service.

++++Installation, Adjustment

FLBS type load break switch has been strictly tested before outgoing from the factory, and fully meet the technical standards, must carefully read the installation manual and prepare as below before the installation and adjustment.
Check the external appearance, any damage product is not allowed to use.
Clean the equipment and get rid of the dust and dirt may cause by the transportation or other causes.
After installation, be sure the load break switch is turned off, insert the handle to the earthing operating hole in the up part of operating panel, and rotate the handle clockwise in 180o to earth the switch, rotate counterclockwise in 180o to switch off the earth.
For switching on, turns off the load break switch firstly, insert the handle to the load break switch operating hole in the lower part of panel and turn on the load switch.
From the switch on to switch off, for K type mechanism, insert the handle to the load switch operating hole and rotate it in 180o to switch off; for A type mechanism, press the "switch off" button to switch off the load break switch, observe from the winder to confirm it, check whether the on/off indication plate works properly.
Notice: only when the load break turns off, can turning on and earthing operation be done !


++++Maintenance & Service
On condition of installing in environment as this manual required and normal operations, product guaranteed to be fault free for 10 years and has a running life of 25 years, but regular check per 6 months is required.

Keep the external appearance away from dust, dirt and damp.
Lubricate and operate the mechanism for 3-5 times, check whether it acts properly.
Check with the pressure meter regularly, in case of meter data lower than 0.01MPa, should reload gas.
When the malfunction happens in the load break switch and fuse combination, and one of the three phase immediately, gas charging should be done by professional personnel from or trained by the manufacturer. uses burns out, all three fuses should be replaced at one time, must earth the switch before the replacement.


++++Matters need attention
It is NOT allowed to disassembly the self-sealed valve in front of switch( connecting end of meter).
It is NOT allowed to unload the seal screws on switch at any time.
