Abstract
The utility model relates to an all-solid-state insulation ring network cabinet which comprises a cabinet body, a bus and a solid sealing electrode post which is installed in the cabinet body. The solid sealing electrode post comprises a shell, a vacuum arc-extinguishing chamber arranged in the shell and an isolation earthing switch. The vacuum arc-extinguishing chamber is disposed in the shell in the transverse direction in pouring mode. The shell is made of epoxy resin in pouring mode. The all-solid-state insulation ring network cabinet has the advantages of novel conception, scientific design and reasonable layout. The solid sealing electrode post is made of epoxy resin in pouring mode. A breaker and the isolation earthing switch are integrally designed so that the all-solid-state insulation ring network cabinet has better insulating properties and can be used in various environments.
