Installation and Mounting
Preparation of the Supporting Structure
The VersaRupter can be applied in vertical or horizontal
operations. The design of a supporting structure shall
consider the geometrical configuration of the VersaRupter
and minimal clearances to both earthed and live parts.
The supporting structure shall be rigid enough to prevent
deformation of the VersaRupter base. All of the mounting
surfaces of the frame shall remain in the same plane. It is
recommended to use U-iron or angle iron components in
the construction of the supporting structure. The Ver-
saRupter should be mounted using four M12 bolts through
the mounting holes in the frame.
Installation of the VersaRupter
Use caution not to deform the base of the VersaRupter
during installation. This could lead to the following prob-
lems:
1. Increased moment of force on the VersaRupter shaft.
2. Contacts not operating simultaneously. Contacts
should not exceed 3 mm in normal conditions.
3. Deterioration of contacts in the closed position.
4. Displacement of the symmetry plane of moving con-
tacts in relation to the pole symmetry plane which
results in asymmetrical contact of the fixed contacts
and moving contacts.
To avoid these defects mentioned above, it is recom-
mended to only tighten three of the mounting bolts when
installing the VersaRupter. The fourth bolt can be
shimmed with additional washers if needed to prevent any
deformation while tightening the fourth bolt.
Do not use the lower or upper insulators for support
during mounting. This may cause misalignment in the
insulators and catastrophic damage during operation.
Note
The VersaRupter should not be installed in an inverted
vertical position with the hollow insulators at the bottom
if it will be subject to water deposition or condensation
on the switch or elements (bus or cable) connected to it.
The switch should be protected against water dripping on
its insulating parts. This situation may cause a deteriora-
tion of the dielectric strength of the switch.
