Description
Technical field
The present invention relates to high voltage direct current field, in particular to a kind of combination tool for replacing direct current grounding pole route suspension string
And method.
Background technique
D.C. high voltage transmission has its unique in terms of remote, high-power conveying electric energy relative to ac transmission mode
Advantage, therefore be widely used in the point-to-point power Transmission of large capacity, overlength distance, Jiangsu, Shanghai are sent in such as western water power east
Etc. ground take the mode of D.C. high voltage transmission extensively.And the livewire work of DC transmission system is concentrated mainly on high direct voltage at present
Route and converter station lack direct current grounding pole route and further investigate, therefore DC earthing line live-line work had both lacked reason
By basis, also lack practical experience.When ground electrode circuit needs replacing suspension string, power failure operation can only be generally used, at this time
The operation of direct current system can be produced bigger effect, directly reduce power supply reliability.
Moreover, direct current grounding pole route current potential is ground potential when hvdc transmission line is under bipolar mode of operation, and in list
Ground electrode circuit then has a high voltage under the operational mode of pole, be generally considered as ground electrode circuit voltage class in actual job ±
50kV.Direct current grounding pole route is because voltage class is lower, and insulation configuration is similar to distribution line, and its current-carrying capacity
Much larger than distribution line, conducting wire is again dramatically different with distribution line.Therefore, when replacing suspension string, direct current grounding pole route band
The Work tool of electric operation can not simply continue to use the Work tool and method of distribution line or hot line maintenance.
Summary of the invention
The purpose of the invention is to overcome the shortcomings of above-mentioned background technique, it is outstanding to provide a kind of replacement direct current grounding pole route
The combination tool and method of vertical string.
In order to achieve the goal above, a kind of combination tool for replacing direct current grounding pole route suspension string provided by the invention,
Including fixture main body, pedestal and connecting screw；The pedestal is the type structure that can be installed between two suspension string hanging point angle steel,
The pedestal is mounted on the bottom surface of the fixture main body by the connecting screw, and the bottom is run through in the connecting screw lower end
Seat simultaneously extends downwardly, and is set on the lower end extended segment of the connecting screw compressible in described two suspension string hanging point angle steel
Clamping plate on bottom surface, the position that the clamping plate bottom surface is corresponded on the connecting screw are equipped with clamp nut, the fixture main body
Both ends are fitted with an anti-torsion wire bar respectively, and an insulated pull rod is respectively connected on each anti-torsion wire bar, and every described exhausted
The conducting wire that one can hook suspension string side of wire is respectively connected on edge pull rod mentions line suspension hook.
Fixture main body is fixed on suspension string shaft tower side by clamping plate and pedestal, and line suspension hook will be mentioned and hooked in suspension string conducting wire
On the conducting wire of side, the tension on suspension string can be transferred to fixture main body, anti-torsion wire bar, insulated pull rod in this way and mention line suspension hook
On, so as to realize the replacement of suspension string；Meanwhile by the way that fixture main body and pedestal are designed to two components so that it is convenient to
The transport of this combination tool, also reduces production cost.
In the above scheme, the bottom surface of the fixture main body is equipped with the fixture bottom surface spiral shell for installing the connecting screw
Hole, the interior pedestal screw hole being equipped with through the pedestal of the pedestal, the pedestal is run through in the connecting screw upper end from bottom to up
Screw hole is simultaneously inserted into the tool bottom surface screw hole to be fixed on the pedestal on the bottom surface of the fixture main body.By screw thread side
Formula connects fixture main body and pedestal, simple and convenient in this way and at low cost.
In the above scheme, corresponded on the side wall of the fixture main body connecting screw upper end position be equipped with it is described
The fixture side wall screw hole of fixture bottom surface screw hole connection, is equipped with for fixing the connecting screw in the fixture side wall screw hole
Screw rod tightening pin.The screw rod tightening pin added can be effectively prevented connecting screw and get loose.
In the above scheme, the position that the connecting screw upper end corresponds to the screw rod tightening pin is equipped with tight with the screw rod
The screw rod tightening slot that rationed marketing matches.The screw rod tightening slot added can prevent from connecting in this way with screw rod tightening pin-shaped at detent
Screw rod is deviate from out of fixture bottom surface screw hole.
In the above scheme, the height h in the clamping portion of the pedestal is less than the height H of the suspension string hanging point angle steel, institute
The space D stated between the width d in the clamping portion of pedestal and described two suspension string hanging point angle steel matches.By by the card of pedestal
The height h in dress portion is designed to the height H less than suspension string hanging point angle steel, in this way, pedestal and clamping plate can tightly be clamped in two
At the upper and lower ends of suspension string hanging point angle steel；Meanwhile by the way that the width d in the clamping portion of pedestal is designed to hang with two suspension strings
Space D between point angle steel matches, and pedestal can be prevented to be subjected to displacement in this way.
