Abstract
The utility model discloses an insulating cylinder structure of a solid insulation breaker. The insulating cylinder is a flat quadrilateral sleeve formed in one. The insulating cylinder is equipped with a cavity for holding a ground switch, a main switch and an isolation switch. A main switch arc extinguish chamber is arranged inside the insulating cylinder. The contact end of the main switch arc extinguish chamber extends into the above cavity and is located in a corresponding position corresponding with the main switch. A bus cable sleeve and an observation window are extended from the insulating cylinder and arranged to be parallel to each other, and the distance A between the bus cable sleeve and the observation window is 230.5mm. The bus cable sleeve and the observation window are formed through all-in-one casting with the insulating cylinder. In the insulating cylinder structure, a cavity is used for holding a ground switch, a main switch and an isolation switch, that three independent switches are combined into one is achieved, a whole body is formed through epoxy casting, phase distance is decreased, cabinet width is decreased, and position accuracy of assembly of three phase switches is raised.
