Description
技术领域technical field
本发明涉及力系统防雷接地领域，尤其是涉及一种快速连接式电力系统接地测量接线装置。The invention relates to the field of lightning protection and grounding of power systems, in particular to a fast-connection type power system grounding measurement wiring device.
背景技术Background technique
电力系统中的接地网是保证整个电系统安全稳定运行的重要保障，其中，接地系统的接地电阻是否合格直接关系到变电站运行人员、变电检修人员人身安全。The grounding grid in the power system is an important guarantee to ensure the safe and stable operation of the entire power system. Among them, whether the grounding resistance of the grounding system is qualified is directly related to the personal safety of substation operators and substation maintenance personnel.
对于运行中的输电线路杆塔，较低的杆塔接地网接地电阻是保证其过电压防护的基本措施。实现杆塔接地网接地电阻的定期检测是输电线路运维的基本工作内容之一。For transmission line towers in operation, the lower grounding resistance of the tower grounding grid is the basic measure to ensure its overvoltage protection. It is one of the basic tasks of transmission line operation and maintenance to realize the regular detection of the grounding resistance of the tower grounding grid.
此外，在变电站接地网、输电线路杆塔接地网建设之前，通过地质、地形勘探、土壤电阻率测量等一系列测量工序才能确定接地网的设计方式。而接地网测量点的地质、地形勘探、土壤电阻率测量等工作均需要接地电阻测试仪进行精确测量。In addition, before the construction of the substation grounding grid and the transmission line tower grounding grid, the design method of the grounding grid can be determined through a series of measurement procedures such as geology, topographical exploration, and soil resistivity measurement. The geology, terrain exploration, soil resistivity measurement and other work of the grounding grid measurement point all need grounding resistance tester for accurate measurement.
长期的电力系统防雷接地领域实践经验表明：现行的接地电阻测量仪自身配备的接地探棒、测量导线并没有设计专门的连接工具，现场测量只能将测量导线的线芯剥开，将铜绞线分别连接接地电阻测试仪与接地探棒。The long-term practical experience in the field of lightning protection and grounding of power systems shows that the grounding probes and measuring wires equipped with the current grounding resistance measuring instrument do not have special connection tools, and the on-site measurement can only be performed by stripping the core of the measuring wire and removing the copper. The twisted wires are respectively connected to the ground resistance tester and the ground probe.
目前这种连接方法存在如下的不足之处：There are following deficiencies in this connection method at present:
第一、连接不牢固，极易松动；由于在测量时受转接头与探测棒的有效接触面积干扰，并且接地探棒表面比较光滑，在接地探棒上面直接环绕裸铜线将极易滑动和松动，使得测量结果往往发生很大的飘移现象；First, the connection is not firm, and it is easy to loosen; due to the interference of the effective contact area between the adapter and the probe during measurement, and the surface of the ground probe is relatively smooth, it will be very easy to slide and touch the bare copper wire directly surrounding the ground probe. Loose, so that the measurement results tend to drift a lot;
第二、每次接地电阻测量都需要剥开测量导线进行连接，不仅破坏导线结构，还会造成材料的严重浪费；Second, every time the grounding resistance is measured, the measuring wire needs to be stripped for connection, which not only destroys the structure of the wire, but also causes a serious waste of materials;
第三、测量效率低，测量时往往需要大量的时间连接各个测量装置，并且每更换一次接地探棒的位置，都需要重复剪线、剥线等繁琐的接线工序。Third, the measurement efficiency is low. It often takes a lot of time to connect various measurement devices during measurement, and every time the position of the grounding probe is changed, tedious wiring procedures such as wire cutting and stripping need to be repeated.
