Abstract
The present invention relates to a high voltage cable connection-peg grounding member, which comprises a nut, an insulation outer choke plug and an insulation inner choke plug, wherein, the nut is embedded into one end of the outer choke plug. The central line of the outer choke plug is a through hole having same circle center with the nut. One end of the through-hole is the embedded nut and the other end is provided with a sealing inner choke plug. The present invention is characterized in that: the other end (the end of contact between the outer choke plug and the inner choke plug) of the outer choke plug is further provided with a strengthening choke plug integrally formed with the outer choke plug. The present invention is provided with the strengthening choke plug integrally formed with the outer choke plug on the outer choke plug so that the outer choke plug of the present invention has a large crawling distance. After the inner choke plug is removed, the cable head has no flashing and puncture in grounding or at interval even if having electricity; therefore electricity examination for electrified conductor and grounding operation can be performed directly, thereby overcoming drawbacks of incapability of intuitive electricity examination and connection of ground line of the high voltage cable connection-peg in the prior art.
Description
Technical field
The invention belongs to a kind of high-tension cable connector, particularly a kind of high-tension cable connector earthing component.
Background technology
High-tension cable connector is to rely on the outer plug of stress cone structure to connect with the turnover wire terminal of switch-box at present, with plug in the epoxy resin charged openend is sealed at last, can realize live part is isolated, can not form live part over the ground with alternate discharge (see figure 1), and for the charged state of cable, being to rely on electrification display to monitor at present, is that the reliability that relies on electrification display realizes.Charged as judging whether by the charged display unit of capacitive, be to tap between coming by an intermediate link (instrument), therefore do not get rid of instrument and be out of order, or intermediate link factor such as make mistakes.If think that directly cable is carried out electrical verification to be difficult for realizing, to take down that plug is infeasible in the epoxy resin before not charged because be sure of cable, reason is just in case charged meeting causes discharge breakdown, has the personal safety problem simultaneously; Console switch also is that the reliability that relies on switch just is achieved to the ground connection of cable.There is the defective that can not carry out electrical verification intuitively and can not carry out the operation of hanging earthing conductor in present in a word employed high-tension cable connector.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can directly carry out electrical verification, can carry out the high-tension cable connector earthing component of the operation of hanging earthing conductor again, to overcome above-mentioned deficiency to cable.
To achieve these goals, the present invention is made of plug in nut, the outer plug of insulation and the insulation, wherein nut embeds an end of outer plug, the center of outer plug is a slotted hole with the nut concentric, the nut of one end of slotted hole for embedding, its other end is provided with plug in the sealing, is characterized in: the other end of plug (outer plug contacts an end with interior plug) also is provided with and the one-time formed reinforcement plug of outer plug outside.
Plug and being connected of outer plug are to interconnect by the internal thread that is provided with in the slotted hole in the outer plug and the external screw thread of interior plug one end setting in above-mentioned.
Also be provided with rubber washer between plug and the outer plug in above-mentioned.
Because the present invention's plug outside is provided with and the one-time formed reinforcement plug of outer plug, make outer plug of the present invention that a large distance be arranged, in removing behind the plug, even cable end is charged, can not take place over the ground or alternate flashover and puncture, thereby can directly carry out electrical verification and ground connection operation to energized conductor, overcome the defective that present employed high-tension cable connector can not carry out electrical verification intuitively and can not carry out the operation of hanging earthing conductor.

Among the figure: plug before plug, 9-rubber washer, the 10-sleeve pipe in 1-switch-box casing, 2-switch-box turnover thread casing joint, 3-switch-box turnover line Binding post/stud, 4-cable, 5-cable splicing ear, 6-nut, the outer plug of 7-, 7.1-slotted hole, 7.2-reinforcement plug, the 8-.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
The present invention is made of plug 8 in nut 6, the outer plug 7 of insulation and the insulation, wherein nut 6 embeds an end of outer plug 7, the center of outer plug 7 is the slotted holes 7.1 with nut 6 concentrics, the nut 6 of one end of slotted hole 7.1 for embedding, its other end is provided with plug 8 in the sealing, and the other end of plug 7 (outer plug contacts an end with interior plug) also is provided with and the one-time formed reinforcement plug 7.2 of outer plug outside.
The present invention when mounted, at first need insert in the preceding plug 10 of sleeve pipe by stube cable 4 according to a conventional method, by plug before the sleeve pipe 10 the cable splicing ear 5 on the cable 4 is inserted in the switch-box turnover line Binding post/stud 3, according to a conventional method outer plug 7 is passed in and out in the line Binding post/stud 3 by nut 6 switch-boxes, make cable splicing ear 5 fastening, then rubber washer 9 is inserted in the outer plug 7, fixing in the slotted hole 7.1 with the outer plug 7 of interior plug 8 screw-ins at last, finish installation process.
Using method of the present invention is: when needing repairing (protecting), at first interior plug 8 is pulled down by the special isolation action bars, carry out direct electrical verification with electrical verification bar contact-making switch case turnover line Binding post/stud 3 or nut 6, when nothing to be determined is electric, use the special isolation action bars that earth connection and switch-box turnover line Binding post/stud 3 is fixing, finish the operation of hanging earthing conductor.After finishing the above-mentioned course of work, again switch-box 1 is carried out safe maintenance (protecting).
The content that is not described in detail in this specification belongs to this area professional and technical personnel's known prior art.
