Abstract
本实用新型涉及输电线路接地线，具体为一种可自由调节输电线路接地线。解决了目前在输电线路高空作业过程中接地线嫩一与引流线相连接的技术问题。一种可自由调节输电线路接地线，包括一个设有呈倒“A”形的钩夹以及与钩夹相连接的绝缘绳的组合式接地线，在组合式接地线的钩夹的末端连接有一个伸缩杆。本实用新型通过一个伸缩杆的简单设计，使得组合式接地线可以通过调节伸缩杆的长度而自由调节钩夹的位置，从而方便的夹住引流线，且能够方便的取下，解决了目前输电线路检修及施工中难以解决的技术问题，且结构简单，成本低廉。
The utility model relates to a grounding wire of a power transmission line, in particular to a grounding wire of a power transmission line that can be adjusted freely. It solves the current technical problem of connecting the ground wire and the drainage wire during the high-altitude operation of the power transmission line. A freely adjustable grounding wire for transmission lines, including a combined grounding wire with an inverted "A"-shaped hook clip and an insulating rope connected to the hook clip. A telescoping pole. Through the simple design of a telescopic rod, the utility model enables the combined grounding wire to freely adjust the position of the hook clamp by adjusting the length of the telescopic rod, so that the drainage wire can be conveniently clamped and removed, which solves the problem of current power transmission Technical problems that are difficult to solve in line maintenance and construction, and the structure is simple and the cost is low.
Description
Technical field
The utility model relates to power transmission line ground wire, and being specially one can free adjustment power transmission line ground wire.
Background technology
Power transmission line ground wire is arranged on shaft tower while being used for line outage operation, can prevent that incoming call, static or thunder and lightning etc. produce unexpected injury to human body suddenly in transformer station both sides.What use at present is composite type earth connection, as shown in Figure 3, this composite type earth connection generally comprises one, and for clamping the hook folder 1 of drainage thread and pressing from both sides 1 insulating cord being connected 2 with hook, insulating cord inside is multiply annealed copper wire, and its end view is roughly down " A " shape.When use, staff stands on shaft tower the hook folder of earth connection is opened, opening is aimed to the drainage thread that is positioned at below, then decontrol hook folder 1, hook presss from both sides 1 middle part and is provided with a contact 4, and for controlling the folding of hook folder 1 and closing, hook folder drops on drainage thread 5(wire) on, contact 4 makes hook folder automatically clamp drainage thread 5 under the effect of impulsive force, and the other end of annealed copper wire is connected with shaft tower 6.After operation completes, catch the upper end of insulating cord, upwards pull earth connection hook folder, just hook folder can be taken off from drainage thread.But in actual use, when staff connects drainage thread on shaft tower, be often difficult to aim at drainage thread, add hook folder and do the movement of falling object, be more difficult to control it and can drop on well realization connection on drainage thread.Therefore need a kind of device that can conveniently earth connection be connected with drainage thread.
Summary of the invention
The utility model is to solve at present earth connection in transmission line high-altitude operation process to be difficult to the technical problem being connected with drainage thread, provides the one can free adjustment power transmission line ground wire.
The utility model is to adopt following technical scheme to realize: one can free adjustment power transmission line ground wire, comprise that one is provided with and is down the hook folder of " A " shape and press from both sides the composite type earth connection of the insulating cord being connected with hook, the end pressing from both sides at the hook of composite type earth connection is connected with an expansion link.
When use, staff stands in the top of drainage thread on shaft tower, and hook folder is opened, and then by expansion link, hook folder is extended near drainage thread, and drainage thread is clamped, and then the insulated wire other end is connected with shaft tower, plays the protective effect to human body; Need to take off hook folder time, as long as catch one end of expansion link, upwards lift, hook folder just can depart from drainage thread.
The utility model is by the simple designs of an expansion link, make length that composite type earth connection can be by adjustable telescopic rod and the position of free adjustment hook folder, thereby clamp easily drainage thread, and can take off easily, solve insoluble technical problem in current power transmission line maintenance and construction, and simple in structure, with low cost.

Embodiment
One can free adjustment power transmission line ground wire, comprises that one is provided with and is down the hook folder 1 of " A " shape and the composite type earth connection with hook folder 1 insulating cord being connected 2, is connected with an expansion link 3 at the end of the hook folder 1 of composite type earth connection.
Described expansion link 3 is the mutually nested structure of more piece connecting rod, and the other end of expansion link 3 is also provided with the handle 6 of ring-type.
Expansion link 3 is that more piece connecting rod is mutually nested, can mutually slide, and free adjustment length scale; The used time can not be set in together, and is easy to carry; Handle 6 is convenient to hold expansion link 3 and is stretched to drainage thread 5 and hook folder 1 is proposed.
Fig. 2 is the schematic diagram of staff 8 while using the utility model.Staff stands on a cross-arm of shaft tower, and it is also a wire that hook folder is stretched to drainage thread 5(by hand-held expansion link) upper, and the other end of insulating cord 2 is connected on shaft tower 7.
