Background technology
In electric power system, consider based on electrical safety, each electric component in high voltage electric equipment and enough air distances will be kept between input-output line, or add insulating material at exposed part.Therefore, when designing, generally reducing equipment size as far as possible, making equipment occupation space less, use material more to economize, so, have employed the method for increase insulation in a lot of place to ensure electrical safety.
Insulating sleeve is that a kind of inside can be conducted electricity and the seal of exterior insulation, is applied to electrical connection, for conductor provides insulation protection, effectively can evade electric discharge that high voltage may cause, puncture, the unsafe condition such as flashover.Existing insulating sleeve generally divides two classes: one wears cable formula, and it utilizes the outgoing cable in equipment directly to pass sleeve pipe, convenient and simple, but this method is suitable only for the situation that conductor small current passes through; And electric current larger time, be then suitable for adopting another kind of sleeve pipe, namely guide rod type, guide rod type is a kind of sleeve pipe of three-decker, and innermost layer is metallic conductor, and conductor outside adds insulation in one deck, is porcelain insulator at outermost layer.But the outlet of guide rod type structure is a corresponding insulating sleeve just, when outlet is many time, busbar will be used, line row is come together respectively, and be equipped with more porcelain insulator, cause following two problems: one, the arrangement of busbar itself is compact, and the arrangement of insulating sleeve can be made more difficult; The corresponding insulating sleeve of its two, line, can make cost very high.
Summary of the invention
The utility model object is overcome above-mentioned the deficiencies in the prior art and provide a kind of multicore guide rod type porcelain insulator sleeve pipe for high-voltage electric power system, this insulating sleeve inside can penetrate conducting rod, thus improve the arrangement architecture of its outgoing line busbar, reduce cost.
The technical scheme realizing the employing of the utility model object is: a kind of multicore guide rod type porcelain insulator sleeve pipe for high-voltage electric power system, comprise porcelain insulator, and conducting rod in the outer conducting rod be located in porcelain insulator and at least one first, described outer conducting rod is hollow form, and described outer conducting rod is shorter than conducting rod in described first, in described first, conducting rod is placed in outer conducting rod, and in described first, the two ends of conducting rod are stretched out from the two ends of outer conducting rod respectively; Insulating resin layer is cast with between conducting rod and outer conducting rod in first, the upper end of described insulating resin layer extends in first between conducting rod upper end and outer conducting rod upper end, and the lower end of described insulating resin layer to extend in first between conducting rod lower end and outer conducting rod lower end; In described first, the two ends of conducting rod and outer conducting rod are equipped with screw thread, and described screw thread all passes through nut check; In described porcelain insulator upper end and first conducting rod upper end nut between be provided with seal gasket, gland, sealant bead and porcelain vase upper cover successively; In described porcelain insulator lower end and first conducting rod lower end nut between be provided with lower seal rubber cushion and guide rod guide vane end stop successively.
Further, in described first, conducting rod is hollow form, and hollow space is inserted in conducting rod in one second again, is cast with insulating resin layer in first in conducting rod and second between conducting rod, and in described second, conducting rod is control line or holding wire.
The utility model has following beneficial effect:
1, the effective difficult design improved because input-output line too much causes.
2, reduce the quantity of porcelain insulator, save space, reduce costs, make outward appearance clean and tidy.
