Advantages of Vacuum over other interrupting
media:
Highest dielectric strength over a small contact gap
Constant low contact resistance
Fastest recovery strength
Lowest arc energy dissipation
Lowest drive energy requirements
Minimum contact erosion
Least number of moving parts and hence highest
reliability
Construction
consist of three poles incorporating the vacuum interrupters
housed in insulated shell. These poles are then covered
completely enclosed. The moving contacts of the vacuum
interrupter are connected to the drive mechanism through
insulated connecting rods. Operating mechanism is of
stored energy type and suitable for auto reclosing duty.
The operation can be manual/electrical as desired. 3AH03
