技术领域technical field
本发明涉及一种架空线维修工具,特别是涉及一种架空线验电接地环线夹护罩带电安装工具。The invention relates to an overhead line maintenance tool, in particular to a live installation tool for an overhead line electric inspection grounding loop clamp shield.
背景技术Background technique
验电接地环的两端分别裸露,一端裸露部分和被剥开的架空线使用连接块连接,另一端裸露部分用于在安全检查时连接接地线夹。The two ends of the electrical test grounding ring are exposed respectively, and the exposed part of one end is connected with the stripped overhead wire using a connecting block, and the exposed part of the other end is used for connecting the grounding wire clamp during safety inspection.
在目前城市配网的中低压线路中(即10千伏及以下电压等级)一般都采用架空绝缘线铺设,而在检修线路或设备时,为了保证检修人员的安全需要验明线路无电后挂设接地保护线,这就要求在挂接地线时接地线夹与电线必须可靠的接触,而绝缘线没办法挂接地线,所以绝缘架空线路上一般设置有验电接地环,在检修线路或设备时验明线路无电。In the current medium and low voltage lines of the urban distribution network (that is, the voltage level of 10 kV and below), overhead insulated wires are generally used to lay. The grounding protection line is set, which requires that the grounding wire clamp and the wire must be in reliable contact when the grounding wire is hung, and the insulated wire cannot be hung with the grounding wire, so the grounding ring for electrical inspection is generally installed on the insulated overhead line. When it is verified that the line is dead.
在绝缘架空线路发生短路故障过程中,导线之间会产生相互吸引或相互排斥的电动力作用,并使得导线产生扭转变形现象。有些扭转变形超出弹性变形范围,当电动力消失后无法恢复原有形态。这种现象导致安装在导线上的验电接地环以导线本身为中心偏转,也无法恢复到与地面垂直状态,不仅影响线路美观,也给导线增加了附加扭矩。当线路停电作业加挂地线时,导线受到的扭矩破坏更大。During the short-circuit fault of insulated overhead lines, there will be mutual attraction or mutual repulsion electromotive forces between the conductors, and the conductors will be twisted and deformed. Some torsional deformations exceed the range of elastic deformation, and cannot return to their original shape when the electromotive force disappears. This phenomenon causes the electrical testing grounding ring installed on the wire to deflect around the wire itself, and cannot return to the vertical state with the ground, which not only affects the appearance of the line, but also adds additional torque to the wire. When the line is powered off and the ground wire is added, the torque damage to the wire is greater.
为使扭转后的验电接地环复位,需要提供一种架空线验电接地环线夹护罩安装工具,使用它实现带电安装验电接地环的线夹绝缘护罩,实现消除验电接地环扭转产生的扭矩对导线安全运行的影响,提高架空线路的安全性。In order to reset the twisted grounding ring for electrical testing, it is necessary to provide an installation tool for the clamp shield of the grounding ring for electrical testing of overhead lines, which can be used to install the insulating shield of the clamp for the grounding ring for electrical testing with electricity, and to eliminate the torsion of the grounding ring for electrical testing The influence of the generated torque on the safe operation of the conductor improves the safety of the overhead line.
