Abstract
The utility model relates to a tool for repairing power transmission line, particularly to an operating rod for grounding wire. The operating rod for grounding wire comprises an insulating rod and a connecting piece installed at the top end of the insulating rod, wherein two or more connecting holes for installing a wire clamp are disposed on the connecting piece, and the included angles between the axes of the connecting holes and the axis of the insulating rod range from 0 to 90 degrees. The technical scheme disclosed by the utility model is an improvement for the connecting piece on the present operating rod for grounding wire, namely, an increase from one to multiple is realized on the quantity of the connecting holes located on the present connecting piece and connected with a wire clamp, and the included angles between the axes of the connecting holes and the axis of the insulating rod range from 0 to 90 degrees, so that installation and detachment for rectangular lead wires, electricity transformation lines and the grounding wires of outdoor lines can be conveniently realized by only utilizing a double-spring bayonet-type wire clamp. The operating rod for grounding wire has the characteristics of being multifunctional and convenient in operation.
Description
Technical field
The utility model relates to a kind of transmission line maintenance tool, particularly a kind of earth connection hook stick.
Background technology
When power transmission lines overhauling, short-circuit grounding wire must be installed, the installation and removal short-circuit grounding wire is to utilize the earth connection hook stick to operate at present.General earth bar is made up of insulating rod, insulating rod and connector, and connector is a tubulose, the wire clamp plug-in mounting in the top, insulating rod is inserted into its lower end, the form that wire clamp is commonly used has plain end screw compression type and two-man act bayonet type.The plain end screw compression type is mainly used in that wire clamp is connected with the busbar of charging equipment in indoor busbar, the power transformation busbar; Like JDX-NL type plain end screw compression type earth rod and flat mouthful of hand held earth rod of JDX-NS type; Be earth connection closely to be contacted with indoor high voltage bus copper bar, have little, the easy to operate advantage of conductive resistance through rotating insulated bar; But the installing ground wire time is long, influences the maintenance progress of equipment.The two-man act bayonet type is mainly used in power transformation circuit and outdoor circuit, and it has easy to operate, only needs that two-man act is connect electricity folder one and hangs one and draw and get final product ground connection, connects advantages such as firm, but can not use on the parallel rectangle lead-in wire of equipment such as transformer.Like this when the parallel rectangle of equipment such as maintenance transformer goes between; Just need to use plain end screw compression type earth bar, and when maintenance power transformation circuit and outdoor circuit, just need to use two-man act bayonet type earth bar; So just need to prepare the earth rod of various ways, to satisfy the needs of different conductor form.
Summary of the invention
In order to overcome defective and the deficiency that prior art exists, the purpose of the utility model provides and a kind ofly can conveniently connect and remove the earth connection hook stick of different conductor form.
The utility model solves the technical scheme that its problem adopted: a kind of earth connection hook stick; Comprise insulating rod and the connector that is installed in the insulating rod top; It is characterized in that having on the connector two or more that connecting hole of wire clamp is installed, the angle of the axis of above-mentioned connecting hole and the axis of insulating rod is 0 °-90 °.
Above-mentioned connecting hole is provided with the fixture of fixing clamper.
The fixture of said fixing wire clamp is the radially fixing hole of opening on the hole wall of connecting hole.
The technical scheme of the utility model is the improvement to existing earth connection hook stick upper connector; Increase to a plurality of by one the connecting hole that is connected with wire clamp on the existing connector; And the angle between the axis of connecting hole and the axis of insulating rod is at 0 °-90 °; So just can only adopt two-man act bayonet type wire clamp just can conveniently realize the installation and removal of the earth connection of rectangle lead-in wire, power transformation circuit and outdoor circuit, have multi-use and convenience operation.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment 1;
Accompanying drawing 2 is the structural representation of the utility model embodiment 2.
Embodiment
Embodiment 1:
As shown in Figure 1, connector 2 is the threeway shape, and wherein the hole of lower end links to each other with the upper end of insulating rod 1, and other two connecting holes 5 are 0 ° and 90 ° of distributions with the axis of insulating rod respectively.When two-man act bayonet type wire clamp 4 be installed in the coaxial hole of insulating rod on the time; Just being 0 ° with the axis of insulating rod is to be prior art; When being installed in insulating rod, two-man act bayonet type wire clamp is on the connecting hole of 90 ° of distributions; Just can be used as the earth connection that the rectangle lead-in wire is installed and use, so just can not adopt plain end screw compression type wire clamp.
Embodiment 2:
As shown in Figure 2,4 connecting holes are arranged on the connector 2, wherein the hole of lower end links to each other with the upper end of insulating rod 1, and the axis of 3 connecting holes 5 and the axis of insulating rod are 90 °, 30 ° and 0 ° of distribution in addition.According to the situation at scene, can wire clamp 4 be installed in the hole in above-mentioned 3 connecting holes.
In above-mentioned two embodiment, the fixture between wire clamp 4 and the connecting hole can adopt existing connected mode, also can be employed in the form that fastens rationed marketing in the radially fixing hole of opening on the hole wall of connecting hole 3, and wire clamp is fixed.
Claims (3)
1. earth connection hook stick; Comprise insulating rod and the connector that is installed in the insulating rod top; It is characterized in that having on the connector (2) two or more that connecting hole (5) of wire clamp (4) is installed, the angle of the axis of above-mentioned connecting hole and the axis of insulating rod is 0 °-90 °.
2. earth connection hook stick according to claim 1 is characterized in that above-mentioned connecting hole is provided with the fixture of fixing clamper.
3. earth connection hook stick according to claim 2, the fixture that it is characterized in that the said fixing wire clamp are the radially fixing hole of opening on the hole wall of connecting hole (3).
