Cheng Feifeng areas) the different voltage of railway contact line or with the double branch additive wires of voltage, the double branch additive wires of different circuit are arranged vertically,
Windage yaw can occur during operation causes insulation distance not enough.In nor'wester area or inshore railway AT powering modes similarly hereinafter bridge
If positive feeder and protective wire between vibrate frequently often occur two additive wires significantly vibrate and the opposite situation of amplitude frequency,
Easily cause between additive wire insulation distance not enough and trip accident, have a strong impact on locomotive and normally run.
When common area Chinese yeast line section runs into wind effect, suspension arrangement horizontal path direction swings larger, it is also possible to
Cause positive feeder with protecting wire spacing not enough and short circuit tripping operation, such accident Zheng Xi high ferros, Lanzhou-Xinjiang high ferro once occurred.Amplitude of oscillation mistake
Greatly, frequency height adds relative motion region and abrasion timeliness between parts, accelerates abrasion between connection parts, can the company of causing
Accumulated fatigue is broken connecting to neutral part in a short time.
Common fixed conductor spacer, installed in being arranged vertically two additive wires such as positive feeders and protective wire or the confession of double branch
Between electric wire, when clue along line direction because the swollen difference of line caused by the temperature difference, or wind effect direction have angle with line direction
When, common fixed conductor spacer can twist, and bent repeatedly with wire fixing end and cause wire fixing point fatigue fracture.
The Northwest's natural conditions are severe, and the signs of human habitation are few, and gobi is more；Wind area wind direction is stable, blows fast；Wind-force is strong, very big wind
Speed is more than 60m/s；Wind phase length, more than 8 grades strong wind number of days were average more than 100 days；The strong wind duration is long, 12 grades and above strong wind
Process duration is most long 40 hours；Coastal area, has sea wind, cyclone and logs in often, wind direction and its unstable, easily produces
It is raw to reverse so that sharp transition occurs for vertically arranged positive feeder and protective wire vibration frequency, it may occur that wire winding, stranded etc.
Accident.
The content of the invention
It is an object of the invention to provide a kind of contact net additive wire slidingtype insulation gap bar device, wind area is solved high
The significantly swing of the additive wire of fast electrification contact network vertical arrangement and thus insulation distance between caused two open traverse
The problem of not enough and short circuit, the vibration amplitude of oscillation is effectively reduced, alleviates wire fatigue and connection parts wear, slidingtype design is effective
Avoid double branch different sizes it is not collinear it is swollen caused by the problems such as reverse caused by difference shifting amount.
The purpose of the present invention is achieved through the following technical solutions：
A kind of contact net additive wire slidingtype insulation gap bar device, on preformed shield lines 5, lower end is installed attached
Plus wire 4, for the insulation being spaced between wire, including directive wheel group 1, insulation gap rod 2 and pre-hinged catenarian cable cleat 3；
Described directive wheel group 1 is hung on preformed shield lines 5 and slided, and the upper end of insulation gap rod 2 is cut with scissors with directive wheel group 1
Connect, the lower end of insulation gap rod 2 is hinged with pre-hinged catenarian cable cleat 3, pre-hinged catenarian cable cleat 3 clamps additive wire 4.
Described directive wheel group 1 includes framework 11, two top sheaves 12, two lower sheaves 13, four pulley pin shafts 14；Two
Individual top sheave 12 and two lower sheaves 13 are left and right symmetrically arranged in framework 11 by four pulley pin shafts 14；Preformed shield lines
5 pass through between two top sheaves 12 and two lower sheaves 13.
The described lower end of framework 11 is hinged by upper bolt pin 6 with the upper end of insulation gap rod 2.
The described middle part composite organic insulator 21 of insulation gap rod 2, two ends are metal forging part 22.
As seen from the above technical solution provided by the invention, a kind of contact net provided in an embodiment of the present invention is additional leads
Line slidingtype insulation gap bar device, solves the additive wire of wind area electrification contact networks of rapid transit railway vertical arrangement significantly
Swing and thus insulation distance is not enough between caused two open traverse and the problem of short circuit, effectively reduces the vibration amplitude of oscillation, alleviates wire
Tired and connection parts wear, slidingtype design is effective to avoid the not collinear swollen caused difference shifting amount of double branch different sizes
Caused by the problems such as reverse.
