Product Description

10kv 13kv 650A 100A HV Switch Vacuum Circuit Breaker With Fuse

 

 

 

What are the specifications of our FK(R)N12A-12D series indoor HV cacuum circuit breaker?

 

1. Description:

FK(R)N12A-12D/T630-20 type indoor AC HV load switch is an indoor three-phase 50Hz 12KV device. It is used for controlling on and off load current, closed-loop current,no-load transformer, cable charging current and on and off short-circuit current. The earthing switch can support short-circuit current.


FK(R)N12D/100-31.5 type AC HV load switch and fuse combination apparatus (short for FN12-12D.R combination apparatus) is a indoor HV apparatus,it is consists of FN12-12D load switch and S_LAJ-12(XRNT_-12) HV current-limiting fuse. It can break any kind of opposite current caused by short-circuit reliably, such as load switch breaking operating current, fuse breaking short-circuit current, joint breaking operating current and dead-short-circuit current.

Machine feature

No. Item Unit FKN12-12D/630-20 FKN12-12D.R/100-31.5
1 Moving contact travel distance mm 218+8-2
2

Static contact travel distance

mm 58±2
3 Auxiliary contact opening distance mm >155
4 Three phases on/off synchronism ms <3
5 Speed at break moment m/s >2.8
6 Speed at close moment m/s >3.8 2.8+0.4
7 Earthing switch fracture distance mm 14.5±5
8 Primary loop resistance μΩ <120 <300
9 Max. operating torque N.m <160 <180

Note:1. auxiliary opening distance value can be equal to the value after 24mm plus distance value of quiet arcing contact to end face of conductive drum nozzie
2. when measuring primary loop resistance of FKN122D combination apparatus, the fuse is instead by current conducting rod whose impedance can be ignored.
