  • Insulating cylinder and a main circuit structure using the same
    Patent number: 9269515
    Abstract: An insulating cylinder and a main circuit structure using the insulating cylinder includes a main cavity, a secondary grounded insert connected with the main cavity, an arc-distinguishing chamber connected with the main cavity, and an outlet terminal insert connected with an end of the arc-distinguishing chamber. An observation window is provided at a side of the main cavity. A main circuit structure using the insulating cylinder, which further includes a main grounded rod and a main grounded contact positioned in the main cavity, an arc-distinguishing chamber insulating pole, an isolated insulating pole, an isolated conductive block, an isolated rod and an isolated contact, and a main bus-bar bushing connected with the isolated contact. A flexible connection is provided between the main grounded contact, the arc-distinguishing chamber and the isolated conductive block.
