Abstract

Aiming at the insulation problems of 40.5 kV contact box

this paper takes the plug-type contact box as the research object.The computation model of 40.5 kV gas insulated switchgear has been established.And the influence of busbar

cabinet bushings

circuit breakers to the electric field distribution of contact box has been considered.The potential and electric field distribution of plug-type contact box has been computed not only in working situation

but also in test situation.The influence of double shield structure on the internal electric field distribution of contact box has been investigated.The structure of double shield has been optimized and the electric field distribution that inside the 40.5 kV contact box has been effectively improved.The research results of this paper can provide computation and analysis basis for the design and manufacture of 40.5 kV plug-type contact box

and improve the safety and reliability of 40.5 kV gas insulated switchgear operation.
