Insulating cylinder and a main circuit structure using the same

摘要

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.

1. An insulating cylinder, comprising:
an insulating cylinder body; a main cavity; a secondary grounded insert connected with the main cavity; an arc-extinguishing chamber connected with the main cavity; and an outlet terminal insert connected with an end of the arc-extinguishing chamber, wherein an outgoing line of the secondary grounded insert is extended from a side of the insulating cylinder; and an observation window is provided at a same side of the main cavity as the outgoing line of the secondary grounded insert; wherein the arc-extinguishing chamber is provided between the main cavity and the outlet terminal insert in a height direction, and wherein an outlet terminal of the outlet terminal insert connected with a lower end of the arc-extinguishing chamber is on a same side as the outgoing line of the secondary grounded insert.
