Abstract

The invention discloses a grounding device arranged at the end of a cable, which comprises a cable fixing part, a cable connection fastening piece and a grounding down part, wherein the cable fixing part is composed of a semicircle-type anchor ear and anchor ear connection rings at both ends of the anchor ear; the cable connection fastening piece comprises a chassis composed of a metal connection tip joint and a fixed ring, and chassis connection rings for lengthening both ends of the chassis; the anchor ear connection rings arranged at both ends of the anchor ear in the cable fixing part are closely connected with the chassis connection rings at both ends of the cable connection fastening piece through screws; the grounding down part is composed of a grounding down connection part, a grounding down wire and a grounding pin. The grounding device arranged at the end of the cable can ensure that the ground device is fixed and unloosened, and that the cable induced electricity generated in the construction process has the same potential as the earth, thereby preventing constructors from being electrocuted due to the induced electricity in the power cable construction process, and ensuring the personal safety in the construction process.

Description

Ground wire apparatus for cable end part
Technical field
The present invention relates to a kind of cable construction safety device, particularly a kind of ground wire apparatus for cable end part.
Background technology
Along with urban construction is accelerated, land resource is more and more nervous, and it is fewer and feweri that power circuit is built passage, and power cable is widely used in power grid construction.But along with urban construction is accelerated, power cable is increased by outside destroy gradually, and the maintenance situation of operation cable also increases thereupon.
But the power cable system of laying is more apart from the parallel laying situation with the ditch pipe range, and the capacity effect of cable makes that induced electricity appears in cable inside in the laid processes, and powerful induced voltage threatens maintenance and workmen's personal safety.
For this reason, in " State Grid Corporation of China's electric power safety working regulation ", the work progress of power cable has been formulated clear and definite organiztion measure and technical measures, further clear and definite in technical measures will power failure, electrical verification, installing earth connection, use individual security personnel's line, hang indication plate and installing is blocked.It is clear and definite that safety management in the construction is required also to carry out refinement.
But at present to installing earth connection technical measures; but can't in the cable construction process, overall process realize; reason lacks the earth connection that is suitable in the cable construction process, causes having serious potential safety hazard in the present cable construction, and the personal safety in the work progress can not get reliably protecting.
Summary of the invention
The objective of the invention is to provide a kind of and prevent that the workmen in the power cable work progress from getting an electric shock because of induced electricity, guarantee the ground wire apparatus for cable end part of the personal safety in the work progress for the deficiency that solves above-mentioned technology.
In order to achieve the above object, a kind of ground wire apparatus for cable end part that the present invention is designed, it comprises that cable holder branch, cable connect securing member and ground connection is drawn the lower part composition, cable holder is divided and is made up of the anchor ear connecting ring at semi-circular anchor ear, anchor ear two ends, and anchor ear is fixed on the cable by core through screw rod; Described cable connects securing member and connects the chassis connecting ring that chassis that most advanced and sophisticated joint and retainer ring form and two ends, chassis extends by metal and form, the chassis connecting ring that the anchor ear connecting ring at anchor ear two ends was connected the securing member two ends during cable holder was divided with cable closely connects with screw rod, make metal connect most advanced and sophisticated joint and closely contact with the cable metal core, guarantee grounding wire device fix, loosening; Ground connection is drawn the lower part and is drawn to descend coupling part, down conductor and grounding pin to be formed by ground connection, by splicing ear down conductor being connected securing member with cable connects, and be connected with the earth by grounding pin, thereby, guarantee the cable induction electricity and the earth equipotential of the generation in the work progress with cable metal and earth potential short circuit.
Metal on the chassis in the described cable connection securing member connects most advanced and sophisticated joint, can be on the chassis, to contain three metals to connect most advanced and sophisticated joint, three metals connect most advanced and sophisticated joint and retainer ring component chassis, so that each the cable metal core in the three-core cable is grounded.In addition, described semi-circular anchor ear is by two involutory structures of embracing of semicircle, also can be by relative another profile of tooth structure of embracing of a semicircle.
The resulting a kind of ground wire apparatus for cable end part of the present invention, can guarantee grounding wire device fix, loosening, ground wire apparatus for cable end part connects tight contact the most advanced and sophisticated and the cable metal part, cable metal and earth potential short circuit, guarantee the cable induction electricity and the earth equipotential of the generation in the work progress, thereby prevent that the workmen in the power cable work progress from getting an electric shock because of induced electricity, guarantees the personal safety in the work progress.
