Problems solved by technology

At home and abroad, when conditions permit, power outage treatment measures are generally taken. In this way, relevant power-consuming units have to be out of power for maintenance, which will cause huge losses. Live work is a new engineering technology, which requires the protection of the sheath induction cable. current limit

Embodiment

[0041] An improved coaxial cable joint live installation process disclosed in the present invention includes the following steps:

[0042] refer to figure 1 , S1, reduce the induced voltage of the cable sheath: use a vacuum circuit breaker 2, the vacuum circuit breaker 2 used in actual operation is an external portable circuit breaker with a vacuum interrupter, connect the vacuum circuit breaker 2 to the cable sheath, so that The cable sheath is grounded to reduce the potential of the cable sheath.

[0043] refer to figure 2 , S2, cable inner core grounding protection: use the puncture tool 3 to pierce the insulation layer 13 of the coaxial cable 1, and ground the coaxial cable inner core, and the wires include the cable inner core 11 and the cable outer core 12.

[0044] refer to figure 1 The piercing tool 3 includes a mounting frame 31, a needle 32, and a grounding wire 33 connected to the needle 32. The end of the grounding wire 33 away from the needle 32 is connected t...

Abstract

The invention discloses an improved coaxial cable joint live installation process, which includes the following steps: S1, reducing the induced voltage of the cable sheath: using a vacuum circuit breaker to ground the cable sheath to reduce the potential of the cable sheath; S2 , Cable inner core grounding protection: Use a puncture tool to pierce the insulation layer of the coaxial cable, and ground the inner core of the coaxial cable; S3, Coaxial cable joint installation: Use a cable joint to splice and install two coaxial cables together; S4. Anti-theft operation of the transposition box: lock the transposition box on the ground with a locking anti-theft mechanism. In the present invention, the operator does not need to perform power outage operation during the process of installing and splicing the coaxial cables, and has the effect of reducing losses caused by power outages to relevant power-consuming units.

Description

technical field [0001] The invention relates to the technical field of a coaxial cable joint installation process, in particular to an improved coaxial cable joint live installation process. Background technique [0002] In order to serve the transformation of urban construction from quantity to quality, the urban distribution network is gradually transforming from overhead lines to underground cables. my country is still in the process of urbanization. With the continuous expansion of cities, the proportion of underground cables in the distribution network is increasing. [0003] As the cable conversion rate is getting higher and higher, more and more cables are used for EHV power transmission, and EHV cables use single-core cables, which requires transposition of the sheath to reduce the stress on the sheath. Inductive current, it is necessary to set the cable grounding wire and sheath transposition box. [0004] At the same time, due to the emergence of a large number o...
