Maintenance serves to preserve trouble-free
operation and achieve the longest possible
working life of the switchgear.In accordance
with DIN 31 051 and IEC 62271-1, it comprises
the following closely related activities:
Inspection: Determination of the actual condition
Servicing: Measures to maintain the specified
condition
Repair: Measures to re-establish the specified
condition
7.1 General
It is essential to observe the following during
all maintenance work:
• The relevant regulations in section 1.2.2
• The notes on safety at work in section 6
• Standards and specifications in the country
where the switch gear is erected
It is recommended that ABB after sales service
personnel be called in to perform servicing and
repair work.
Follow/observe the instructions on SF
6
systems
and the ABB instruction manual on the handling
of insulating gases and procedures for fault
conditions.
• Keep these instructions and manual permanently
on display and available in the switchroom
The inspection and servicing intervals for the
switching devices are determined by fixed criteria
such as switching frequency and number of
short-circuit breaking operations.
The length of the intervals for inspection and
servicing of the control cabinet and its equipment
is influenced by ambient conditions (for instance
pollution and aggressive atmosphere).
7.2 Inspection/servicing
• Under normal operating conditions (see section
1.3), inspection (visual examination) of the
operating mechanisms is to be carried out bya
suitably qualified electrician after 5,000 operating
cycles of the circuit breaker and 1,000 operating
cycles of the three position switch. Attention is
also drawn to instruction manual 1YHA000118
• In exceptional operating conditions (including
adverse climatic conditions) and/or particularly
adverse environments (including heavy
contamination and aggressive atmosphere)
inspection at shorter intervals may be required
• Inspection is first and foremost to be visual
examination for contamination, corrosion
and moisture
• The inspection should however also include
checking of the mechanical and electrical
functions of the following devices
- Switching devices
- Multifunction protection and switchbay
control unit.
• If an incorrect condition is found, the
corresponding repair work is to be initiated
immediately
Cleaning of external surfaces
• Remove dry, poorly adhering dust deposits with
a soft, dry cloth
• Clean off more strongly adhering dirt with slightly
alkaline household cleanser and a moist cloth,
not allowing any liquid to penetrate inside the
low voltage compartment and the operating
mechanism bays. Observe the manufactures
instruc tions for cleaning of the front surfaces
of the equipment installed in the door
7.2.1 Vacuum circuit breaker
• The vacuum circuit breaker has a long service life.
It has a low maintenance operating mechanism
and the breaker poles are maintenance-free
Consult the relevant sections of instruction
manual BA 463/E for further information.
7.2.2 Three-position switch
• The three-position switch is maintenance-free
for 2000 operating cycles
7.2.3 Gas system and gas servicing
• Consult the relevant sections of instruction
manual for further information
• Caution when working in the gas
compartment con cerned! The gas
concentration may causea danger of
asphyxiation!

7 Maintenance/disposal
• Sealed pressure system according to IEC 62271-1
SF
6
gas contained in this system shall be recycled
and not released into the atmosphere.
7.3 Repair
7.3.1 Replacement of drive mechanism parts and
accessories
Only remove and reassemble drive mechanism
parts and accessories when the breaker has been
switched off and the working area is to be isolated
and secured against reclosing. The spring energy
store must be discharged.
All supply voltage sources must be disconnected
and secured against reclosing during the removal
and installation work.
7.3.2 Checking the dimensional accuracy of the
settings (Figure 7/1)
After work which may be necessary on the circuit
breaker or three-position switch when the optional
mechanical interlock is fitted, the following checks
are necessary:
• The distance between lever (1.28) operated bya
link rod and plastic cam (1.26) is to be 2
+1
mm
• There must be space between lever (1.28) and
OFF release shaft (1.25)
• If correction is necessary,tie wire (2.35) is to
be adjusted:
- Release clamping screw (1.30) on clamping
piece (1.29)
- Align flap (2.22) in such a way that the two
bores (2.23) are in alignment
- Fasten tie wire (2.35) with clamping screw
(1.30) in such away that the
abovementioned distance of 2
+1
mm is
achieved. The tie wire must not be tensioned
7.3.3 Touch up of surfaces
• Sheet steel parts, painted
- Remove rust, e.g. with a wire brush
- Grind off paint coat and grease
- Apply anti-rust primer and top coat
- Use top coat paint in the standard colour
RAL 7035, or the relevant special colour
• Sheet steel parts, with aluminium-zinc surface
and passivated functional parts
- Remove white rust with a wire brush or
cleaning pad (e.g. Scotch-Brite white)
- Remove loosely adhering particles with a
dry cloth
- Apply zinc spray or zinc dust primer
• Functional parts, phosphated
- Remove rust with a wire brush or cleaning
pad (e.g. Scotch-Brite white)
- Clean with a dry cloth
- Grease with Isoflex Topas NB 52
