The invention relates to a telescopic grounding resistance test wire and belongs to the technical field of electric power testing. The left end of a left shaft and the right end of a right shaft are connected with a box body through first bearings, the right end of the left shaft and the left end of the right shaft are connected with a support rod through second bearings, and the support rod is fixedly connected with the box body; a left wire coil is arranged on the left shaft, a right wire coil is arranged on the right shaft; one end of each spring is connected with the corresponding second bearing, and the other end of the spring is connected with the outer side of the corresponding wire coil. According to the telescopic grounding resistance test wire, the telescopic design is adopted, so that manpower can be saved; and when a front-line worker encounters inspection and acceptance of a large batch of transformers, time waste caused by winding of a grounding resistance test wire is avoided. Due to the simple structure, the manufacturing and using cost of the telescopic grounding resistance test wire is low, and the economical efficiency of the telescopic grounding resistance test wire is good.
Description
technical field [0001] The invention relates to the technical field of electric power testing, in particular to a retractable grounding resistance testing line. Background technique [0002] The test line of the currently used grounding resistance tester needs to be manually wound up after the measurement, which wastes a lot of time and is easy to cause line confusion when coiling the line, and brings a lot of unnecessary troubles when it is used for the second time. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention proposes a retractable ground resistance test line. Simple structure, convenient operation, high efficiency grounding resistance test line. [0004] The invention provides a retractable grounding resistance test line. Two wire holes are arranged on the side of the box body (5), one is the wire hole for the ground wire end (2), and the other is the wire hole for the test wire end (6). ; [0005] T...
