Problems solved by technology

[0003] However, the existing insulating poles have a single function and can only realize one function. If floating objects such as plastic sheets, kites, and publicity balloons are encountered on the transmission line during maintenance, these floating objects will endanger the safety of the transmission line. Safe to operate, requires processing
Although these floating objects can be moved through the insulating pole to make the floating objects fly away, but in this way, the floating objects will fall on other transmission lines, which is completely a temporary solution, and does not completely remove the floating objects. will continue to jeopardize the safe operation of transmission lines

Embodiment 1

[0037] like figure 1 As shown, the present invention provides a multi-functional insulation holding rod that can replace the high-voltage drop-out fuse with electricity, including an insulation rod 1, a wire locker 2 arranged at the end of the insulation rod, and the insulation rod 1 includes an upper rod 11 and a lower rod. The rod 12, the upper rod 11 and the lower rod 12 are connected by a connecting piece, and the connecting piece includes a clamping piece for fixing the insulating rod on the cross arm, an elastic member for realizing the loosening operation of the clamping piece, and a clamping piece for the clamping piece The limit member that prevents the upper rod and the lower rod from disengaging when loosened. The thread locker 2 is arranged on the upper end of the upper rod 11 and the lower end of the lower rod 12. The advantage of this setting is that the thread locker at both ends of the upper rod and the lower rod The upper and lower lead wires can be locked sep...

Embodiment 2

[0048] The difference between this embodiment and the first embodiment is that it also includes a foreign matter removal flame spraying device that can replace the thread locker.

[0049] In this example, if figure 2 As shown, the insulating pole also includes a foreign matter removal flame spraying device 3 used to replace the thread locker. The foreign matter removal flame spraying device 3 includes a base 31, a control unit located in the base 31, an ignition mechanism and a spraying mechanism, and the base 31 is an aluminum alloy base, the base 31 is provided with a mounting hole 311, the mounting hole 311 is a threaded hole, the upper end of the upper rod 11 is provided with an external thread, and the foreign matter removal flame spraying device 3 is fixed by the cooperation of the external thread and the threaded hole. On the upper end of the upper rod 11, the upper rod 11 and the lower rod 12 are telescopically arranged to adjust the length of the insulating rod. The ...

Embodiment 3

[0059] The difference between this embodiment and the first and second embodiments is that it also includes a wire clip lock used to replace the wire locker.

[0060] In this example, if image 3 As shown, the clamp lock 4 includes a clamp body 41 and a clamp lock plate located on the clamp body 41, the clamp body 41 is provided with a mounting hole 411, and the clamp lock plate includes a first clamp plate 42 and a second clamp plate 43. The second clamping plate 43 is movable relative to the first clamping plate 42 to change the clamping distance between the first clamping plate 42 and the second clamping plate 43. By arranging the wire clamp lock used to replace the wire locker, the insulation holding bar has other functions, that is, a The insulating rod is matched with multiple tool heads, and different functions can be realized when different tool heads are installed, that is, one insulating rod can realize various operations, and there is no need to bring multiple insul...

Abstract

The invention provides a multifunctional insulated holding pole allowing live replacement of a high-voltage drop-out fuse. The multifunctional insulated holding pole comprises an insulating rod and awire locker. The insulating rod comprises an upper rod and a lower rod. The upper rod and the lower rod are connected by a connecting member. The connecting member comprises a clamping member for fixing the insulating rod on a cross arm, an elastic member for realizing the elastic operation of the clamping member, and a limiting member for preventing the upper rod and the lower rod from being detached when the clamping member is loosened. The insulating rod further includes a foreign matter removing fire-spraying device used in the replacement of the wire locker. The foreign matter removing fire-spraying device includes a base, a control unit disposed in the base, an ignition mechanism and a spraying mechanism. The base is an aluminum alloy base. The base is provided with a mounting hole therein. The mounting hole is a threaded hole. The upper end of the upper rod or the lower end of the lower rod is provided with an external thread. The foreign matter removing fire-spraying device isfixed to the upper end of the upper rod or the lower end of the lower rod by the cooperation of the external thread and the threaded hole. The upper and lower rods are telescopically arranged to adjust the length of the insulating rod, thereby realizing the versatility of the insulated holding pole.

Description

technical field [0001] The invention relates to the technical field of power equipment auxiliary tools, in particular to a multi-functional insulating holding rod capable of replacing a high-voltage drop-out fuse with electricity. Background technique [0002] In order to follow the principle of "quick" emergency repairs for distribution network accidents, ensure the reliability of power supply for users, and increase the amount of power supply, the task of emergency repairs for live shifts is becoming increasingly severe. Among them, the insulation holding pole operation method in 10 kV live work has the advantages of wide application range, simple operation and small investment, and is widely used in live work in the electric power industry. [0003] However, the existing insulating poles have a single function and can only realize one function. If floating objects such as plastic sheets, kites, and publicity balloons are encountered on the transmission line during mainten...
