Tools
1.
Overhaul of breaking
chambers
•
Line and transformer
circuit-breakers
•
Capacitor bank circuit-
breakers
•
Reactor circuit-
breakers
•
Filter circuit-breakers
•
All kinds of service.
Not synchronized:
2,500 CLOSE/OPEN operations
with el. load.
Synchronized:
5,000 CLOSE/OPEN operation with
el. load.
Alarming result at diagnostic test.
Gas evacuated, poles/ breaking units
dismounted and transported to a clean
workshop.
Porcelain lift off, contacts and PTFE-
parts replaced with new ones.
See Manual Overhaul Instruction for
actual circuit-breaker.
Standard tools, close fitting dust mask,
long sleeved overall, protective plastic
or rubber gloves.
See Manual Overhaul Instruction for
applicable circuit-breaker.
2.
Major overhaul of
complete circuit-
breaker and operating
mechanism
30 years or 10,000 mech.
CLOSE/OPEN operations.
Circuit-breaker.
Disassembly of the poles and
mechanisms. New contacts and PTFE-
components are to be mounted.
Exchange of outer worn out parts.
If the circuit-breaker and operating
mechanism are overhauled for another
2,000 operations, selected worn out
parts are to be exchanged.
If the circuit-breaker and operating
mechanism are overhauled for another
10,000 operations, in principle all
moving parts are to be exchanged.
Protection against decomposed gas as
standard tools above.
Instructions:
For circuit-breaker, see Manual
Overhaul Instructions for actual circuit-
breaker.
Operating mechanism under
supervision from ABB.
3.
Capacitor
30 years or 10,000 mech.
CLOSE/OPEN operations.
