Maintenance
General
The recloser switch unit of the SDR vacuum
recloser is designed to require no
maintenance for 10,000 operating cycles
under ANSI/IEEE C37.60 “usual service
conditions.” Regular monitoring and, if need
be, replacement of the batteries is necessary
for the three-phase type SDR controller.
Regular maintenance is required for
components in the controller, primarily
consisting of checks of cleanliness, tightness
of connections, battery test and similar
activities.
Maintenance plan
The following work should be carried out as
part of regular inspections reflected in Table
3.
Spare parts
Spare parts must be replaced only by
instructed and certified personnel. Refer to
list in Table 4.
Hazardous voltages.
Will cause death, serious injury or property damage.
Always de-energize and ground the equipment and all terminals before
performing any work near high-voltage conductors.
Work on the recloser switch unit or the control cubicle should be
performed only by qualified personnel.
Do not open the inner panel of the control cubicle, as interior parts
energized at voltages higher than 50 V are present.
Do not disconnect control or sensor cables while recloser is energized,
as connectors contain energized parts.
