Description
Technical field
The utility model belongs to power transmission lines overhauling technical field, and in particular to ± 500kV DC power transmission line simply connected lists
It hangs V-type composite insulator string and replaces wing type clamp apparatus.
Background technology
At present, ± the 500kV that Yunnan Power System has put into operation rich DC power transmission lines forever, have that conductor load is big, span is big, electricity
The features such as gas gap is big, gold utensil, big insulator tonnage, and there are the fitting assembly pattern of various structures, traditional 500kV exchanges
Power transmission lines overhauling technology cannot meet live practical.In ± 500kV, rich DC transmission line road has largely used tangent tower forever
Simply connected list hangs V-type composite insulator string structure, and there are no a set of fixtures to match with the structure gold utensil to transport for branch company at present
For replace simply connected list hang V-type composite insulator string, to DC line service work bring larger impact in addition to direct current it is defeated
Electric line safe and reliable operation brings certain influence.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model provides, one kind is simple in structure, easy for installation ±
500kV DC power transmission line simply connecteds list hangs V-type composite insulator string and replaces wing type clamp apparatus.
Its technical solution is：
± 500kV DC power transmission line simply connecteds list hangs V-type composite insulator string and replaces wing type clamp apparatus, including wing type clamp apparatus
Body, wing type clamp apparatus mounting groove, wing type clamp apparatus flank, yoke plate construction plate, the wing clamp is especially by threaded hole and bolt and connection
Plate construction plate connection, the wing type clamp apparatus flank are connect with screw, and the screw is connect with insulation pull-rod, and the insulation pull-rod leads to
Connector is crossed to connect with tower head construction plate.
Further, the wing type clamp apparatus flank is two.
When hanging V-type composite insulator string wing type clamp apparatus using ± 500kV DC power transmission line simply connecteds list, wing type clamp apparatus installation
It is connected at slot with yoke plate construction plate, the specific two wing type clamp apparatus flanks of wing clamp are connect with screw, screw and insulation
Pull-rod connects, and insulation pull-rod is connect by connector with tower head construction plate, completes a whole set of load supporting system tool assemble.
The utility model is rational in infrastructure, stress science, and is made of high-strength aluminum alloy, can meet operation completely
It is required that.The wing type clamp apparatus of offer is fully able to satisfaction ± 500kV DC power transmission line simply connecteds list and hangs the replacement of V-type composite insulator string
Service work, this method greatly reduce operating personnel's labor intensity.It is the utility model design science, simple in structure, easy for installation.
± 500kV DC power transmission line simply connecteds list is carried out using the utility model and hangs the replacement of V-type composite insulator string, operation effect can be improved
Rate reduces security risk.
