7. Commissioning
7.1 General procedures
When commissioning, all operations must be carried out by suitable
qualified customer personnel with in-depth knowledge of the
apparatus and the installation itself.
It is not recommended to open AutoLink under charge using a
common hookstick, as it could cause an arc that might damage the
personnel or the equipment. The AutoLink has horns to be used with a
load break tool. There is also a LoadBreak AutoLink for opening under
load.
8. Maintenance
Test the correct operation of electronic sectionalizer on a regular basis, preferably while
maintenance on head recloser is made:
- Check the closing system.
- Check that the interlocking bolt turns freely. The tensioning device support should move
easily and the spring should be sufficiently tightened so that the support may reset when
the system opens following the operation of the sectionalizer.
- Check that the mobile lever and the lower support of the AutoLink move easily at the joint.
Clean and lubricate the joint surfaces of both pieces.
- Keep contact zones clean and place a thin film of conductive grease on those zones.
- Keep the tripping pin clean.
- Check the upper contact cap is correctly fastened and both the o-ring and the silicon
grease are present.
Test should be carried out on a laboratory with the appropriate equipment to simulate
service conditions. For this operation it is recommended to contact ABB to request the
testing procedure.
