According to the delivery, handover and preventive test regulations of electrical equipment, a large number of high-voltage tests are carried out annually in the power industry. The electrical equipment is connected to the test instrument through the test wire, one end of the test wire is a test clamp, the other end of the test wire is a test column, the test clamp is connected with the tested electrical equipment, and the test column is connected with the test instrument. Currently, most commonly used test clips in the industry are crocodile clips, test clamps and the like, and the reliability of the joint is determined by the biting force of the test clip. In the case of developing a high-voltage test, the test wire clamp is disconnected and falls down, and the high voltage can cause damage to equipment and personnel.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a test wire clamp convenient to fix, and the reliability of connection between the test wire clamp and a tested device conductor is improved.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a test fastener of convenient fixed, includes the crocodile clamp, the clamping mouth both sides of crocodile clamp are equipped with the rivet, and the fixed line both ends are connected with two sets of rivets respectively, and the fixed line twines in the outside of the clamping mouth of tested conductor and crocodile clamp.
In a preferred embodiment, the fixing line is an elastic rope.
In the preferred scheme, fixed ring is equipped with to fixed line one end, and fixed ring suit is on the nail pole of one of them group rivet, and the other end is equipped with the split ring, is equipped with the opening that supplies the nail pole of another group rivet to penetrate on the split ring.
In the preferred scheme, the opening of split ring is equipped with the connection piece, and the connection piece is connected with the fixed line, is equipped with the "L" shape import with the opening intercommunication on the connection piece.
According to the test wire clamp convenient to fix, the crocodile clamp can be prevented from being opened to fall off through winding of the fixing wire, and meanwhile, the connection strength of the test wire clamp and a tested conductor can be improved, and falling is further prevented. The test wire clamp can effectively resist falling of the test wire clamp caused by wind power, human factors, lead gravity and the like, ensure the safety of equipment and test personnel, and ensure the safety completion of high-voltage electric test.
Drawings
The utility model is further described below with reference to the accompanying drawings and examples of implementation:
FIG. 1 is a schematic illustration of the placement of rivets;
FIG. 2 is a schematic view of a structure of a fixing line;
in the figure: crocodile clip 1, rivet 2, fixing wire 3, fixing ring 4, split ring 5, connecting piece 6, opening 501, and "L" shaped inlet 601.
Detailed Description
As shown in fig. 1-2, a test wire clamp convenient to fix comprises a crocodile clamp 1, wherein the crocodile clamp 1 is a conventional crocodile clamp, rivets 2 are arranged on two sides of a clamping opening of the crocodile clamp 1, two ends of a fixing wire 3 are respectively connected with two groups of rivets 2, and the fixing wire 3 is wound on the outer sides of a tested conductor and the clamping opening of the crocodile clamp 1.
Through the winding of fixed line 3, prevent on the one hand that crocodile clamp 1 that wind-force, human factor, wire gravity etc. caused opens and cause and drop, on the other hand twines on the conductor being tested through fixed line 3, can improve the joint strength of this test fastener and the conductor being tested, further prevent to drop.
Preferably, the fixing wire 3 is an elastic rope. The rubber rope can be selected specifically, the tensile capacity is strong, the rubber rope is not easy to break, and the rubber rope can be suitable for joint conductors of tested equipment with different sizes.
Preferably, one end of the fixing wire 3 is provided with a fixing ring 4, the fixing ring 4 is sleeved on the nail rod of one group of rivets 2, the other end of the fixing wire is provided with an opening ring 5, and the opening ring 5 is provided with an opening 501 for penetrating the nail rod of the other group of rivets 2.
The fixing ring 4 and the opening ring 5 are of sheet structures, the size of the inner ring of the fixing ring 4 is slightly larger than the size of the shank of the rivet 2 and smaller than the size of the head of the rivet 2, so that the fixing ring 4 and the rivet 2 are reliably and fixedly connected. An opening 501 is formed in one side of the split ring 5, and the rivet can be detachably connected with the split ring 5 by penetrating the shank of the rivet 2 into the split ring 5 from the opening 501.
Further, the opening 501 of the split ring 5 is provided with a connecting piece 6, the connecting piece 6 is connected with the fixing wire 3, and the connecting piece 6 is provided with an L-shaped inlet 601 communicated with the opening 501. By providing the connecting piece 6 and providing the connecting piece 6 with an "L" shaped inlet 601, it is possible to advantageously prevent the shank of the rivet 2 from coming out of the opening 501 of the split ring 5.
The working principle of the test wire clamp is as follows:
the fixed ring 4 of fixed line 3 one end is fixed in one side of crocodile clamp 1 through rivet 2, and crocodile clamp 1 presss from both sides on the test equipment conductor, and fixed line 3 is through twining or perforating (when the test equipment conductor foraminiferous) on the test equipment conductor, and the split ring 5 of fixed line 3 other end detains to establish on the nail pole of another group rivet 2, realizes crocodile clamp 1 fixed on the test equipment conductor.
The test wire clamp can effectively resist falling of the test wire clamp caused by wind power, human factors, lead gravity and the like, ensure the safety of equipment and test personnel, and ensure the safety completion of high-voltage electric test.
