The insulating cylinder comprises a cylinder body, wherein symmetrically distributed connecting blocks are convexly arranged on the end parts of the two ends of the cylinder body; and a plurality of uniformly distributed fixing holes are formed on the connecting blocks. The symmetrically distributed connecting blocks are arranged at the two ends of the cylinder body; the fixing holes are formed on the connecting blocks; the two ends of the cylinder body are respectively provided with an insulating top cover and a bottom plate through the connecting blocks and the fixing holes; mounting through holes in the cylinder body are formed into a sealed test cavity through the bottom plate and the insulating top cover; a global information system (GIS) terminal is arranged in the test cavity; and a shielding electrode is sleeved on the GIS terminal, so that the electric field distribution of the GIS terminal and the electric field distribution of a practical circuit are ensured to be the same; an outlet rod is arranged at the other end, which is provided with the GIS terminal, of the cylinder body; and the outlet rod is electrically connected with the GIS terminal. A corresponding test can be performed on the GIS terminal by loading a test voltage on the outlet rod. The insulating cylinder has a simple structure, is convenient to mount and use, and is good in insulating effect, safe and reliable because the insulating cylinder is made from an epoxy glass fibre reinforced plastic.
Description
Technical field
The utility model relates to a kind of cylindrical shell, especially a kind of insulating cylinder, and specifically a kind of cylindrical shell that is used for GIS terminal experimental rig belongs to the technical field of power equipment.
Background technology
Employing GIS(Gas Insulated Switchgear) the cable form of terminal has two kinds of situations usually: first kind of situation is that an end is the GIS terminal, and the other end is an outdoor terminal; Second kind of situation is that two ends are the GIS terminal.At present, no matter adopt which kind of GIS terminal form,, the insulation of GIS terminal is difficult to effective solution all the time when needs during to the GIS terminal; Simultaneously, during to GIS terminal test, need guarantee that insulator arrangement takes corresponding hydraulic pressure and air pressure.
