Fully SF6 gas insulated single and double busbar GIS switchgears up to 36 kV in accordance

with IEC Standards

IG-137-EN version 03; 24/06/2016

7.7.2 Main busbar earthing

Initial conditions

: feeder disconnectors open,

earthing switches open and circuit breaker

open.

1. First connect the left feeder disconnector by turning

the lever clockwise.

Figure 7.56

Lever turn detail

2. Then connect the right earthing switch by turning the

lever clockwise.

Figure 7.57

Lever turn detail

3. The circuit breaker closes instantaneously on removal

of the driving lever.

Figure 7.58

Circuit breaker closed detail

To open the earthing connection, earth

connection, reverse the sequence of operation:

first, open the circuit breaker by acting on the

bottom pushbutton, then the earthing switches

and lastly open the feeder disconnectors.

The circuit breaker opening operation is always

performed manually.
