Gas-insulated high-voltage conductor

gas insulated busbar elbow, high-voltage sf6 gas insulated busbars, busbars GIL

Connection of two shielded gas-insulated 100 kV lines.

Problem type:
3D-import electrostatics.

Geometry:

Given:
Electric permeability of SF₆ gas ε = 1;
High voltage U = 100 * √2 kV (amplitude)

Task:
Determine the levels of electric field strength.

Solution:
Geometric model is built in a third-party CAD and imported into QuickField.
There is no field inside the metal conductors, so only gas-insulated insulation is included in the model. On the surface of the conductor an electric potential is set.
For convenience the model is dissected along the plane of symmetry.

Results:

Electric field intensity distribution (SF₆ gas electrical strength 89 kV/cm is not exceeded):
