The company IVEP, a. The switching device leaves
the manufacturing plant properly assembled and adjusted condition which guarantees machine
parameters for the whole duration its service life, providing the manufacturer maintenance
recommendations are adhered to. the gearing found satisfactory, only needs re-
greased.
- the current-carrying path needs replaced also the layer the contact surfaces becomes
damaged, the temperatures measured the current-carrying path under operation during a
temperature-rise test exceed the following:
75°C contact
90°C incoming screw-type terminals
The values above represent limit values apply for non-galvanized copper.s. The torque values can found in
dimensional sketches appendix this accompanying documentation.
Upon attaining the limits mechanical service life the user has assess further usage options the
switching device.D0064.
- status check the HF, and RCV gearboxes; assessment the condition spur gearing, angle
transmission and screw-type gearing.
- retightening all terminals the electric drive mechanisms
- verification mechanical operation the disconnector
- tightening screws incoming terminals the switching device.PD.01/2017

cleaning and lubrication, recommend using the "Omnigliss-Spray" from Don Corning that provides
for better ingress the lubricant the bearing slot. the values measured
are per cent excess those entered the documents, the current-carrying path needs to
be replaced.
The manufacturer recommends the following actions carried out:
- measure the resistance the main (power) current-carrying path (voltage drops) and compare these
with the corresponding values entered the accompanying documentation. strongly disadvises any disassembly works and unprofessional
modifications carried out the disconnector main components
