Abstract
The utility model relates to an insulating cylinder used for high-voltage solid insulating switch equipment, and aims to provide an insulating cylinder which has a simple structure, is reliable, exhibits good electrical performance and enables an upper portion and a lower portion inside the cylinder to be isolated. The insulating cylinder is divided by a vacuum pipe mounting zone (5) of the enclosed insulating cylinder with the upper portion isolated from the lower portion into an upper cavity and a lower cavity, i.e., an upper isolation switch mounting zone (7) and a lower isolation switch mounting zone (2). An upper isolation sleeve pipe mounting hole (8) is communicated with the upper isolation switch mounting zone (7), and a lower isolation sleeve pipe mounting hole (1) is communicated with the lower isolation switch mounting zone (2). A connecting bus (6) is inlaid into a narrow sidewall of the insulating cylinder between the vacuum pipe mounting zone (5) and the upper isolation switch mounting zone (7). An upper end and a lower end of the connecting bus (6) extend into the upper isolation switch mounting zone (7) and the vacuum pipe mounting zone (5), respectively. A central portion of the sidewall, inlaid with the connecting bus (6), of the insulating cylinder, is provided with a rear blocking mounting hole (4). A lower portion of the sidewall is equipped with a grounding column mounting hole (3).

Sealed insulating barrel is the agent structure of high-voltage appliance switch equipment, can realize modularized design, realizes the independent assortment of kinds of schemes.Be widely used in the power supply of the ring network power supply of urban distribution network, each distribution system and terminal, also be applicable to transformer station, power distribution station, have totally-enclosed, all insulation, non-maintaining, compact conformation and reliability high.Traditional insulating cylinder generally only has bottom or top to adopt inlet-outlet sleeve, and only has an isolating switch installing zone, the quiet end connection bus of its vacuum tube, described bus is not embedded on the sidewall of insulating cylinder, and be arranged in parallel with vacuum tube, the mode that is arranged in parallel can cause two electric fields between the electric conductor to influence each other, and then causes internal field inhomogeneous.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, and is reliable and stable, has good electric property, and section can realize the insulating cylinder of isolating up and down within it.
The utility model is isolated up and down sealed insulating barrel, is shaped as cuboid, and the upper middle side part of described insulating cylinder is provided with the first boss, has the disrance sleeve installing hole in the first boss; The lower middle side part of insulating cylinder is provided with the second boss, has lower disrance sleeve installing hole in the second boss.The middle part of insulating cylinder is the vacuum tube installing zone, and the vacuum tube installing zone is divided into up and down two cavitys with insulating cylinder, is respectively isolating switch installing zone, lower isolating switch installing zone.Described upper disrance sleeve installing hole communicates with upper isolating switch installing zone, and lower disrance sleeve installing hole communicates with lower isolating switch installing zone.Be inlaid with connection bus on the narrower sidewall of insulating cylinder between described vacuum tube installing zone and the upper isolating switch installing zone, an end of connection bus reaches in the isolating switch installing zone, and the other end reaches in the vacuum tube installing zone.Be provided with a rear shutoff installing hole at the middle part of the insulating cylinder sidewall that is inlaid with connection bus, the bottom is provided with an earthing rod installing hole.
The utility model is isolated up and down sealed insulating barrel, and the aperture of wherein said rear shutoff installing hole reduces from outside to inside gradually, is shaped as taper shape.
The utility model is isolated up and down sealed insulating barrel, and wherein said insulating cylinder is made by epoxy resin.
The utility model is isolated up and down the sealed insulating barrel difference from prior art and is that the utility model is provided with up and down two isolating switch installing zones, adapt therewith, be provided with up and down two sleeve pipe installing holes in the utility model, and the connection bus that connects vacuum tube is to be embedded in the sidewall of insulating cylinder, so the utility model is simple in structure, reliable and stable, have good electric property, and section can realize isolating up and down within it.
The utility model is isolated up and down the taper shape that is shaped as of rear shutoff installing hole in the sealed insulating barrel, carries out shutoff after being convenient to like this install.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the cutaway view that the utility model is isolated up and down sealed insulating barrel;
Fig. 2 is the left view that the utility model is isolated up and down sealed insulating barrel;
