Novel solid ring main unit

The utility model discloses a novel solid ring main unit. The ring main unit comprises a housing body, a vacuum circuit breaker arc-distinguishing chamber arranged in the housing body, an isolation switch moving end moving touch seat and an isolation switch static end. The vacuum circuit breaker arc-distinguishing chamber is horizontally arranged. The left end of the vacuum circuit breaker arc-distinguishing chamber is connected with a cable port via an insulating sleeve, and the right end is connected with the isolation switch moving end moving touch seat via a conductor. A movable isolation conductive rod is arranged on the isolation switch moving end moving touch seat. Closing operation can be achieved between the isolation conductive rod and the isolation switch static end. The isolation switch static end is connected with an expendable bus via a bus insulator. According to the utility model, a high-voltage electrified body can be completely wrapped in the housing body at a time, and the bus is in an inserted connection with the cable, so whole sealing and whole insulating of the whole ring main unit are achieved.
