Description
Technical field
The present invention designs the transmission line technical field, particularly a kind of assembly type suspension bridge outgoing line device.
Background technology
In recent years, along with the increase day by day of electricity needs and the development of technology of transmission of electricity, UHV transmission lines such as 800kV, 1000kV have begun to build at home and put into operation.At gradation for surface pollution than the important place district; Adopt composite insulator to dodge ability, prevent and contain that the generation of pollution flashover accident all can play positive role, and composite insulator has advantages such as cost is low, non-maintaining improving the transmission line resistant; In the ultra high voltage engineering, apply remarkable benefit.
But conventional strain insulator string generally adopts glass insulator (or porcelain insulator); When the staff need carry out the outlet operation; Can climb to the enterprising line operate of lead from transmission tower through directly trampling climbing conventional glass (or pottery) insulator string.
After the ultra high voltage strain insulator-string adopts composite insulator,, can not bear operating personnel's climbing and trample because composite insulator material resources intensity is relatively poor, fragile.This just makes also that in UHV transmission line the staff can't carry out the outlet operation through the climbing insulator string, for work such as maintenance have brought great inconvenience in the conventional mode.
Above-mentioned technical problem present stage a part adopted in the ultra-high-tension power transmission line of electric pressure below 500kV of compound inslation substring also and existed.But because the transmission line electric pressure of this part 500kV is lower, thus composite insulator length less (generally in 5 meters), so can solve through the mode that whole suspension bridge is installed.But in UHV transmission line, the length of compound inslation substring is generally more than 10 meters.The whole suspension bridge of well imagining 10 meters spans of installation in the high-altitude is and is loaded down with trivial details, is difficult to realize; Even realize that reluctantly fail safe and practicality also can't guarantee, and cost is too high at all.
So present stage lacks a kind of outgoing line device, can be implemented under the prerequisite of not damaging the compound inslation substring, help the staff to accomplish out line process.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of assembly type suspension bridge outgoing line device, be implemented under the prerequisite of not damaging the compound inslation substring, help the staff to accomplish out line process.
For realizing above-mentioned purpose, the present invention has following technical scheme:
A kind of assembling suspension bridge outgoing line device, said device concrete structure is following: said device comprises, two hold-down supports and a plurality of assembly type standard knot; Said hold-down support is fixed on the gold utensil at compound inslation substring two ends, forms the assembly type suspension bridge by the assembly type standard knot between two hold-down supports; Link to each other with drift bolt through draw-in groove between the assembly type standard knot or between assembly type standard knot and the hold-down support; Said assembly type standard knot comprises two hangers, and said two hangers are suspended on adjacent two and meet on the insulator string.
Said hold-down support is the L type, and an end is fixed on the triangle yoke plate of compound inslation substring one end, and the other end assembles the formula standard knot through draw-in groove and drift bolt.
Said assembly type standard knot is a stripe shape, and the assembly type standard knot is connected hold-down support or connects other assembly type standard knots through draw-in groove with drift bolt.
The assembly type standard knot that is connected with hold-down support is provided with the lengthening bolt hole, is used to regulate the length of assembly type suspension bridge.
The selection of said assembly type standard knot is fiberglass, aluminium alloy or stainless steel.
Said hanger has anchor ear, and said hanger is suspended on the compound inslation substring through anchor ear.
Said anchor ear has the anchor ear liner, and the material of anchor ear liner is an ethylene-vinyl acetate copolymer.
Can know through above technical scheme; The beneficial effect that the present invention exists is; Utilize the hold-down support of assembly type suspension bridge outgoing line device according to the invention to be fixed on the gold utensil at compound inslation substring two ends, between two hold-down supports, utilize the assembly type standard knot to constitute the assembly type suspension bridge, the assembly type standard knot utilizes hanger to be suspended on the compound inslation substring simultaneously; The staff can pass through on said assembly type suspension bridge and accomplish out line process, has avoided trampling and climbing for the compound inslation substring; In addition, said hanger has utilized the design of anchor ear and liner when suspension, more effectively protected the compound inslation substring, can not cause the damage of compound inslation substring.
