Description

Many core insulations control sleeve pipe

Technical field

The utility model is related to for the insulating sleeve in power system, and in particular to a kind of many core insulations sleeve pipe is controlled.

Background technology

In large-scale power equipment, many control lines are generally comprised, control action is played to each several part of equipment.To protect Card electrical safety, will reserve enough air distances during the design of each electrical equipment and wire, or in exposed part addition Insulating materials, it is to avoid high voltage may cause during operation electric discharge, puncture, the unsafe condition such as flashover.Insulation in power system Sleeve pipe is that a kind of inside is electrically conductive and the insulating materials of exterior insulation, is generally used for electrical connection, is conductor (control line) Insulation protection is provided, the normal operation of equipment is ensured.

Guide rod type insulating sleeve is a kind of sleeve pipe of three-decker, and innermost layer is metallic conductor, and conductor outside adds in one layer Insulation, is porcelain insulator in outermost layer.Outgoing cable in equipment is passed through from guide rod type insulating sleeve, more in cable When, one kind is that, using many insulating sleeves, every cable is through an insulating sleeve, but so arrangement meeting of insulating sleeve It is extremely difficult, reduce equipment using space, and cost is very high；Another kind is that multi-cable passes through same insulation sleeve Pipe, so can adopt less insulating sleeve, compact conformation, but the insulation between the multi-cable in an insulating sleeve With regard to becoming problem, and cable is very inconvenient through the wiring after insulating sleeve, needs to install other devices additional in addition, increased Design difficulty.

The content of the invention

The utility model aims to overcome that above-mentioned the deficiencies in the prior art and provides a kind of many core insulations and control sleeve pipe, is somebody's turn to do Sleeve structure is simple, can simultaneously use many conductors, and can guarantee that insulating properties each other, and cost economy.

Realize that the technical scheme that the utility model purpose is adopted is that a kind of many core insulations control sleeve pipe, it includes insulation porcelain Bottle, patchplug and conducting rod, the conducting rod is inserted in interior in the porcelain insulator, and the top of conducting rod is from porcelain insulator Pass；The patchplug is pressed on the top of the conducting rod by aluminium gland；Oil is filled inside the conducting rod, many are led Line is immersed in oil, and the multiple conducting wires are connected through conducting rod with the patchplug.

In above-mentioned technical proposal, the conducting rod is provided with screw thread, and nut check is passed through at screw thread.

In above-mentioned technical proposal, between the porcelain insulator and conducting rod seal gasket is provided with.

In above-mentioned technical proposal, lid, the upper lid and porcelain insulator are additionally provided between the porcelain insulator and nut Between be provided with sealant bead.

The utility model has the advantages that：

1. porcelain insulator quantity is reduced, and compared to existing technology, the utility model only needs a porcelain insulator, reduces production Cost, outward appearance neat appearance；

2. the Insulation Problems between many control cables of single inside pipe casing in prior art are solved, by conducting rod Insulating oil ensure that reliable dielectric strength；

3. the wiring difficulty of many control cables is improved by patchplug.

Description of the drawings

Fig. 1 is the structural representation that many core insulations of the utility model control sleeve pipe.

In figure：1- porcelain insulators, 2- seal gaskets, 3- sealant beads are covered, 5- securing members, 6- patchplugs on 4- porcelain vases, 7- conducting rods, 8- aluminium glands.

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described in further detail with specific embodiment.

As shown in figure 1, many core insulations of the utility model control sleeve pipe, including porcelain insulator 1, patchplug 6 and conducting rod 7, conducting rod 7 is inserted in interior in porcelain insulator 1, and the top of conducting rod 7 passes from porcelain insulator 1；Patchplug 6 passes through aluminium pressure Lid 8 is pressed on the top of conducting rod 7；Oil is filled inside conducting rod 7, during multiple conducting wires (connection cable) are immersed in oil, and many are led Line is connected through conducting rod 7 with patchplug 6.Seal gasket 2 is provided between porcelain insulator 1 and conducting rod 7.

In the present embodiment, tapping on conducting rod 7 is locked at screw thread by securing member (nut shim etc.) 7.Porcelain insulator 1 Lid 4 on porcelain vase are additionally provided between securing member 7, sealant bead 2 is provided with porcelain vase between lid 4 and porcelain insulator 1.

The utility model ensures the insulating properties between the multiple conducting wires in it by the oil in conducting rod 7, meanwhile, many are led Line is connected to the patchplug 6 on the top of conducting rod 7, so as to realize connecting multiple conducting wires in an insulating sleeve, facilitates and connects Line.Compared to existing technology, the utility model simple structure, cost economy realizes multiple conducting wires by a porcelain insulator Connection, and ensure that the insulating properties between wire.
