Abstract
The utility model relates to a cable line grounding based on metal sleeve. The cable line comprises a plurality of successively serially connected cable bodies, wherein each coaxial cable is serially connected between every two adjacent cable bodies; the two ends of each coaxial cable are in parallel connection with one transposition case; the first cable body and the last cable body are respectively connected with a first grounding case; and second grounding cases are arranged between the cable bodies and the coaxial cables. Compared with the prior art, the metal sleeve grounding-based cable line has the advantages of high safety and good reliability.
Description
Technical field
The utility model relates to a kind of cable line, especially relates to a kind of cable line based on metallic sheath ground connection.
Background technology
In recent years, China 110KV, 220KV extra-high-tension cable are used in electric power system widely, and the extra-high-tension cable circuit is also more and more longer.Because extra-high-tension cable dead weight, the restriction of production and transportation and big length line influence voltage can have the extra-high-tension cable of the big length of use of placing restrictions on, therefore need and to be spliced than short cable, but spliced safety problem and integrity problem become urgent problem instantly.
The utility model content
The purpose of this utility model is exactly to provide a kind of cable line based on metallic sheath ground connection for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of cable line based on metallic sheath ground connection, it is characterized in that, comprise the cable body that multistage is connected successively, be serially connected with coaxial cable between the adjacent segment cable body in twos, these coaxial cable two ends are parallel with the transposition case, all be connected to the first ground connection case on first section cable body and the final stage cable body, be provided with the second ground connection case between described cable body and the coaxial cable.
Be provided with the first measuring voltage table between described transposition case and the coaxial cable.
Be provided with the second measuring voltage table between the described first ground connection case and the cable body.
Be provided with the 3rd measuring voltage table between the described second ground connection case and the cable body.
Compared with prior art, the utlity model has safe, good reliability, solved spliced induced voltage problem well, thereby improved safety of construction.
