Description

Technical Field

[0001] The utility model relates to the technical field of electrical tests, and particularly to a wire fixing clamp for electrical tests. Background Art

[0002] At present, when conducting electrical tests on primary and secondary electrical equipment in a substation, the test instrument is directly connected to the electrical equipment under test using a test wire, without any fixing measures in between. First, when the test wire used is thick and heavy, the weight of the test wire will be entirely borne by the wiring terminal of the electrical equipment under test. If the plug-in connection method is used, it is easy to cause deformation and damage to the wiring terminal of the electrical equipment under test. If the alligator clip connection method is used, the clamping force of the alligator clip is insufficient, and the test wire is likely to fall off. Second, when conducting outdoor tests and encountering strong winds, the test wire sways with the wind, and the test wire is likely to fall off during the test, resulting in test interruption and affecting the test results. Third, when conducting live tests in a narrow space, if the test wire falls onto the live equipment, there is a risk of equipment short-circuit burnout and personal electric shock.
