Problems solved by technology
[0002]In the prior art, the solid state switch mainly adopts a three-phase integrated structure of epoxy resin, which is too large in size, heavy in parts, low in space utilization, and complex in electric field. The insulation performance is not ideal, and as the switchgear becomes more and more miniaturized, the existing solid switch has limited the development trend of solid insulated ring network switchgear
