Instruction of Pole Mounted 31.5KA Combinations FT16 Load Break Disconnect Switch 630A

FT16-40.5,FT16-40.5R is applied in power grid with AC 50HZ,rated voltage of 35Kv.It can be applied in breaking the load current,overload current and short-circuit current.The product is the main element of HXGT16-40.5 indoor AC metal-clad switchgear and DFT16-40.5 outdoor HV cable branch box.HXGT16 is especially designed for 35KV compact substation ,secondary small scale distribution substation.It is particularly the best choice of wind turbine generator system and power transmission gri equipment for control and protection of the transformer terminal.DTW is a transit station for power transmission cable ,used for outdoor cable line control ,contact,tap,branch or conversion.

Feature of Pole Mounted 31.5KA Combinations FT16 Load Break Disconnect Switch 630A

1. In order to arc prevent extinguish chamber and fuse failure to affecting the normal operation of other circuits. The visible isolation fracture is installed in front of the arc extinguish chamber, divided into two parts and installed in a different compartment, when problems arise, you can carry out the security maintenance and repair, other circuits can also be in normal work to improve the user efficiency and easily maintained and repair. And fuses and isolation switch are mounted at each side of the switch, when replacing the fuse, after separating arc extinguish chamber and opening the isolation switch, there will be adequate safety distance between the high pressure and maintenance personnel, it is more convenient and secure.

2. Arc extinguish chamber adopts the solid seal poles, through advanced automatic pressure gel (APG) to directly solid seal the vacuum arc extinguish chamber and other components of the main circuit in epoxy resin, which not only beautify the pole assembly process, but also to prevent the vacuum vacuum arc extinguish charmber conductive circuit connection from loosing the bolts due to the vibration, and improving its reliability, and the vacuum arc extinguish charmber outdoor surface cannot be effected by the external mechanical force and the external situation (such as dust , moisture, contamination, high altitude, small animals), only through this way it will further improve the electric distribution of the pole.

3. Take the load switch and isolation switch to respectively operate, but both have reliable mechanical interlock to prevent the malfunction occurrence.

4. Have installation of special spring mechanic and closing function depends on storage spring, which can operated by motor and manual, it is not only labor-saving and convenient,but also to achieve automatic control.
