Description
Technical field
This utility model is related to a kind of rubber fixture block, relates in particular to a kind of ADSS built-in lining keel formula rubber fixture block.
Background technology
All Dielectric self-support（All Dielectric Self-Supporting Optical Fiber Cable,
Hereinafter referred to as ADSS）ADSS optical cable is that recent two decades to be developed in power system and a kind of wide variety of special despatch
Optical cable, ADSS optical cable utilizes power system power transmission tower bar, and self-supporting hangs on the minimum position of electric field intensity on electric power tower.It is fitted
For built ultra-high-tension power transmission line, because it saves the comprehensive method of investment, decrease the artificial damage of optical cable, safe, no electromagnetism/strong
Electrical interference, span is big, is deeply favored by vast power system customer.Build in the communication of power system urban network restructuring, the upgrading of rural power grids
If in be used widely.It is typically erected at the ground line position of transmission and distribution line line pole tower, plays lightning conducter in system operation
Dual compound action with order wire.OPGW and ADSS optical cable when installing and using, typically using by base shaft, tower is optimum directly connects
The mode on ground, this mode has advantages below：
Direct grounding way, can be when circuit be struck by lightning or system short-circuit occurs, directly will be short to lightning current or system
Road conduct current the earth, improves the reliability of ground connection lightning protection.Due to the electromagnetic field, ground wire and the electric power that produce around electrical lead
Electromagnetism and Electrostatic Field Coupling can be produced between wire.While OPGW and ADSS optical cable is directly grounded, ground wire and ground wire it
Between can by the earth constitute loop, formed two ground wires line between circulation.Additionally, every lightning conducter is again respectively with the earth as loop,
Form faradic current loop, the taking of this mode, its result is exactly to bring substantial amounts of parasitic power wastage for transmission line of electricity.
Another ground wire joint used in some power transmission sequences for the needs of energy-conservation, carried out ground wire for bar,
The insulating mounting of tower.This results in two ground wires on shaft tower top, and resistance to earth difference is very big.When meeting with thunderbolt,
Lightning current selects, because being directly grounded, to cause resistance value less OPGW and ADSS optical cable to carry out earial drainage, cause a lot of OPGW first
With ADSS optical cable because thunderbolt is broken the generation of fine, stranded accident, the safe operation of OPGW and ADSS optical cable is brought huge hidden
Suffer from.
It is obvious that OPGW and ADSS optical cable composite ground wire is carried out after insulating mounting, can effectively solving above-mentioned two problems
Generation.In OPGW and ADSS optical cable composite ground wire insulating mounting, it is considered as construct custom, line maintenance, operation maintenance etc.
The requirement of aspect.This require continue or at steel tower cross-arm can by OPGW and ADSS optical cable composite ground wire carry out rationally,
Reliable insulation is fixed.
Utility model content
For OPGW and ADSS optical cable composite ground wire continue or steel tower cross-arm at insulating mounting fix shortcomings and deficiencies, this
The purpose of utility model is to provide a kind of ADSS built-in lining keel formula rubber fixture block, has clamping and consolidates, be dielectrically separated from reliability, stablize
Etc. characteristic, it is suitable for long-term, field, runs under natural conditions.Described technical scheme is as follows
The utility model proposes a kind of ADSS built-in lining keel formula rubber fixture block, including two rubber fixture blocks, described two rubber folders
It is provided with installing hole, described installing hole both sides are respectively arranged with the groove running through along its side length, when two rubber press from both sides in the middle part of block
During block compression, the groove corresponding formation clip slot of described two rubber fixture blocks, also it is embedded with nonmagnetic in described two rubber fixture blocks respectively
Sheet metal, described sheet metal and rubber fixture block are profile-followed and are smaller in size than rubber fixture block, are provided with through hole in the middle part of described sheet metal,
Described through hole is overlapped with the installing hole of rubber fixture block.
Preferential as technique scheme, described two rubber fixture blocks are made using EPDM.
The utility model proposes a kind of ADSS built-in lining keel formula rubber fixture block, it is embedded with profile-followed nothing in every piece of rubber fixture block
The sheet metal of magnetic, every suit wire clamp can save two external sheet metals compared with the retained part of existing 4 parts composition, tool
Have functions that to save raw material and installation work-hour；This utility model can according to the particular/special requirement of power system, using in 220kV and
In the above insulating mounting of OPGW and ADSS optical cable composite ground wire.
