Inspection and maintenance
Summary
After the process of installation and testing, the switchgear
is available to use. Timely and proper maintenance can keep
the switchgear trouble-free and can prolong the life of the
switchgear as long as possible.
The maintenance work must be carried out by certified persons
who are familiar with the related operations of the switchgear
and understand relevant IEC and other local safety rules and
important guides established by other technical departments
as well. Allow a GE representative to assist when the switchgear
and its components need to be repaired. Users should think
about the operating environment and the operation frequency
when developing maintenance rules. Usually the inspection of
some equipment / components (such as wearable parts) and
the maintenance intervals (maintenance period) depend on
the running time, operating frequency and the number of short
circuit cycles. The maintenance period of other parts depends on
the working situation, the degree of the load and environmental
impact (including pollution and corrosive gasses).
Inspection and maintenance interval
The maintenance interval determined by operating conditions of
the switchgear depends on the operating mode, the operating
number of rated current and short circuit current, environment
temperature and pollution.
The recommending maintenance interval is showed in the
following table:
