Abstract
The utility model provides a test fixture for the loop resistance of a circuit breaker. The fixture comprises an insulating rod, a test line, a voltage test contact finger, a clamp, a current test contact finger, and a near-electricity alarm device, wherein one end of the clamp is inserted into the top of the insulating rod; an upper contact jaw and a lower contact jaw at the other end of the clamp are fixedly connected with the current test contact finger and the voltage test contact finger respectively; the near-electricity alarm device is arranged at the top of the insulating rod; and file surfaces are arranged on the outer surfaces of the voltage test contact finger and the current test contact finger. The fixture provided by the utility model has the effect that test personnel can finish test wiring by using the test fixture without the need of ascending a height, thus ensuring a safety distance between the test personnel and live equipment, and eliminating the potential safety hazards of personal electric shock; and the test personnel can finish test work only by standing on the ground, thus absolutely avoiding a height-falling risk and saving working hours by more than 60%.
Description
Technical field
The utility model relates to a kind of outfit of testing current in resistance property that belongs to, particularly a kind of isolating switch loop resistance test fixture.
Background technology
Along with the grid equipment electric pressure improves, the equipment distance to the ground is increasing, and during test, the wiring link exists height to fall potential safety hazard and problem such as serious consuming time, when particularly the isolating switch loop resistance was tested, classic method needed 2 people upward to operate above transmission facility at least.For 110kV isolating switch or combined electrical apparatus, the sleeve pipe height surpasses 2 meters, during test connection, needs the tester to climb up sleeve pipe, it is very dangerous to work together, and since the isolating switch long-time running out of doors, metal part is because oxidation, cause test result inaccurate, need repeatedly test repeatedly, waste time and energy.
Summary of the invention
At structural deficiency in the prior art, the purpose of this utility model provides a kind of isolating switch loop resistance test fixture, is beneficial to reach safe, time saving and energy saving, increases work efficiency.
For achieving the above object, the technical solution adopted in the utility model provides a kind of isolating switch loop resistance test fixture, and wherein: these anchor clamps include insulating bar, p-wire, voltage tester fingertip, clamp, testing current fingertip, alarming in short range of electric power device; One end of described clamp inserts the top of insulating bar, the pawl that touches up and down of the clamp other end is fixedly connected with testing current fingertip, voltage tester fingertip respectively, be provided with the alarming in short range of electric power device at the top of described insulating bar, the outside surface of described voltage tester fingertip and testing current fingertip is equipped with the file face.
Effect of the present utility model is to use this test fixture realization testing crew to need not to ascend a height can finish test connection, has guaranteed the safe distance of tester and charging equipment, has eliminated the potential safety hazard of personal electric shock.The tester only need stand on the ground can finish test job, and 100% has avoided height to fall risk, and can save more than 60% man-hour.

Embodiment
Reaching embodiment by reference to the accompanying drawings is illustrated the structure of isolating switch loop resistance test fixture of the present utility model.
Shown in Fig. 1-5, isolating switch loop resistance test fixture structure of the present utility model is that these anchor clamps include insulating bar 1, p-wire 2, voltage tester fingertip 3, clamp 4, testing current fingertip 5, alarming in short range of electric power device 6; One end of described clamp 4 inserts the top of insulating bar 1, the pawl that touches up and down of clamp 4 other ends is fixedly connected with testing current fingertip 5, voltage tester fingertip 3 respectively, be provided with alarming in short range of electric power device 6 at the top of described insulating bar 1, the outside surface of described voltage tester fingertip 3 and testing current fingertip 5 is equipped with the file face.
Described alarming in short range of electric power device 6 is the galvanoscopic commercially available finished products of GSG type 35kV.
The structure of isolating switch loop resistance test fixture of the present utility model is achieved in that
The insulating bar 1 of described isolating switch loop resistance test fixture plays support, connects each parts effect, voltage tester fingertip 3 and testing current fingertip 5 are separately fixed at the different parts of clamp 4, voltage is guaranteed measuring accuracy in interior, electric current requirement outside when satisfying test both opens device outlet terminal.Alarming in short range of electric power device 6 plays anchor clamps and reports to the police near charging equipment the time, avoids getting an electric shock.
When using the test of isolating switch loop resistance test fixture, with anchor clamps 4 tested isolating switch outlet terminal is enclosed within respectively on voltage tester fingertip 3 and the testing current fingertip 5 earlier, p-wire 2 carries for testing tool.The tester stands in the root that insulating bar 1 is held on ground, gently to the isolating switch direction firmly, being positioned at anchor clamps diverse location touches pawl 4 about two test fingertip voltage tester fingertips 3 and testing current fingertip 5 this moment moves to isolating switch distance both direction respectively, must satisfy the voltage of test point in interior, electric current requirement outside, simultaneously in the process that moves, by the coarse surface of voltage tester fingertip 3 and testing current fingertip 5, the oxide layer of isolating switch terminal surfaces is removed, be beneficial to guarantee that test data is accurate.
Utilize insulating bar 1 transformation of the way test fixture, voltage tester fingertip 3 becomes the file face with testing current fingertip 5 with the surface design of tested isolating switch outlet terminal, rely on gravity that test point is closely contacted with the isolating switch surface of contact, earlier test point is eliminated rust before the test, will introduce error and drop to minimum.The head of insulating bar 1 is integrated alarming in short range of electric power device 6 is set simultaneously, in case cross nearly just warning apart from charging equipment, prevents mistake and bumps charging equipment.
Realize by unit clamp that testing crew need not to ascend a height and to finish test connection, reach safety, purpose efficiently.
