Abstract
Provided is a method for inverse climbing cross arm replacement for a live line, wherein according to the method, power outage operation is not needed, vertical bottles are replaced quickly, and normal power supply is guaranteed. The method comprises the steps of first installing a high voltage cross arm on a wire pole through a U-shaped bolt, installing a first inverse climbing cross arm at one end of the high voltage cross arm, arranging a first vertical bottle group on the first inverse climbing cross arm, enabling a wire to be wound around the first vertical bottle group; installing a second inverse climbing cross arm on the high voltage cross arm, installing a second vertical bottle group on the second inverse climbing cross arm; unwinding the wire wound around the first vertical bottle group and enabling the wire to be wound around the second vertical bottle group; replacing a new first inverse climbing cross arm and a new vertical bottle group; unwinding the wire wound around the second vertical bottle group and winding the wire around the new first vertical bottle group; finally dismantling an insulating package blanket and a wire shielding cover, and enabling the first vertical bottle group and the second vertical bottle group to be respectively connected with the first inverse climbing cross arm and the second inverse climbing cross arm respectively through built-in bolts on the vertical bottles.
Description
Technical field
The present invention relates to a kind of alive circuit and change the method for climbing cross-arm.
Background technology
Insulation can not be ensured after vertical bottle on alive circuit bursts, due to the corrosion of vertical bottle nut, change very difficult.Existing replacing options to carry out replacing process after line outage again, can not realize quick-replaceable vertical bottle like this, can not ensure again power supply.
Summary of the invention
The present invention is the deficiency solving the existence of existing replacing options, provides a kind of alive circuit to change the method for climbing cross-arm.Can realize not needing power failure operation, quick-replaceable vertical bottle, ensure normal power supply.
Alive circuit changes a method of climbing cross-arm, and its step is as follows:
1, first install on utility poles by high pressure cross-arm by U-bolt, high pressure cross-arm one end is on utility poles installed and is climbed cross-arm I, and this is climbed on cross-arm I and is provided with vertical bottle group I by connecting bolt, and each vertical bottle on this vertical bottle group I is wound around a wire respectively;
2, use charged insulating bucket arm vehicle operator to be delivered to the position of the vertical bottle group I that will change, operator wears insulating gloves and uses insulating bag blanket and wire mask to be wrapped up by the electrified body closed on;
3, be positioned on high pressure cross-arm climb install that an insulating material makes by fixture inside cross-arm I climb cross-arm II, climb cross-arm II and climb cross-arm I distance >=400mm, being provided with vertical bottle group II climbing on cross-arm II;
4, again the electric wire be wrapped on vertical bottle group I is taken off respectively on the vertical bottle group II being wrapped in correspondence respectively with it;
5, then by climb cross-arm I unload and more renew climb cross-arm I and vertical bottle group I;
6, again electric wire is taken off from vertical bottle group II and be wrapped on new vertical bottle group I respectively corresponding with it;
7, finally to dismantle insulating bag blanket and wire mask, utilize aerial lift device with insulating arm for live working that operator is placed on ground and fulfil assignment.
Described vertical bottle group I, vertical bottle group II respectively with climb cross-arm I, climb cross-arm II and be connected respectively by the built-in bolt in vertical bottle.
The invention has the beneficial effects as follows: on utility poles by a U-bolt installation high-voltage cross-arm, high pressure cross-arm one end is installed and is climbed cross-arm I and vertical bottle group I; That climbs cross-arm I by using interim replacement climbs cross-arm II by wire intertwist thereon, and achieve and do not need to have a power failure, quick-replaceable vertical bottle, ensure that normal power supply.
Accompanying drawing explanation
Fig. 1 is operation chart of the present invention.
Embodiment
As shown in the figure, this alive circuit changes the method for climbing cross-arm, and its step is as follows:
1, first on utility poles by U-bolt installation high-voltage cross-arm, install in high pressure cross-arm one end and climb cross-arm I, this is climbed on cross-arm I and is provided with vertical bottle group I by connecting bolt, and each vertical bottle on this vertical bottle group I is wound around a wire respectively;
2, use charged insulating bucket arm vehicle operator to be delivered to the position of the vertical bottle group I that will change, operator wears insulating gloves and uses insulating bag blanket and wire mask to be wrapped up by the electrified body closed on;
3, be positioned on high pressure cross-arm climb install that an insulating material makes by fixture inside cross-arm I climb cross-arm II, climb cross-arm II with climb cross-arm I distance in 400mm(actual mechanical process >=400mm, to ensure safe distance), be provided with vertical bottle group II climbing on cross-arm II;
4, again the electric wire be wrapped on vertical bottle group I is taken off respectively on the vertical bottle group II being wrapped in correspondence respectively with it;
5, then by climb cross-arm I unload and more renew climb cross-arm I and vertical bottle group I;
6, again electric wire is taken off from vertical bottle group II and be wrapped on new vertical bottle group I respectively corresponding with it;
7, finally to dismantle insulating bag blanket and wire mask, utilize aerial lift device with insulating arm for live working that operator is placed on ground and fulfil assignment.
Described vertical bottle group I, vertical bottle group II respectively with climb cross-arm I, climb cross-arm II and be connected respectively by the built-in bolt in vertical bottle.
