A simplified model of a solid insulation RMS was setup with or without shielding and Grounded coating of outer surface of the solid insulation RMU. The electric field distribution has been calculated using Ansoft Maxwell 3D. The influence of the grounded coating on the overall insulation performance was studied by analyzing the internal electric field of the vacuum circuit breaker, the busbar chamber and the circuit breaker chamber. When the surface of the solid insulating material is grounded, the electric field intensity in the air gap between the embedded pole of circuit breaker and the metal material is too large. The comparison results are available for reference to optimization design of insulating structure for a 12kV solid insulation RMU.
