Description
Technical field
This utility model relates to power department detection instrument, is specially a kind of earth-continuity tester and changes formula connecting plug.
Background technology
In power department transformer station, power equipment needs to be connected ground connection with the earth mat being embedded in underground, as shown in Figure 2 by band iron and wire.At present, operation maintenance personnel uses earth-continuity tester to detect whether charging equipment is reliably connected with earth mat by band iron, it is ensured that charging equipment is in good ground state all the time.One group of I on earth-continuity tester+Binding post and V+Binding post connects wire respectively, and wire is wound on bobbin, and two wires are connected with simple homemade locking-type plug again, and plug is exactly briefly that wire termination fixes two taper irons by being wound around insulating tape and ambroin connection.In like manner, the group of another on earth-continuity tester I-Binding post and V-Binding post also connects another plug.Wherein, one plug inserts at the connection band iron of power equipment, the next junction point that the grounded screen that is connected to another plug elevates above the soil, detected the resistance of this band iron by earth-continuity tester, if in qualified scope, then show that this equipment and grounded screen are in the state of being reliably connected, if test resistance is beyond acceptability limit, the most likely show that this equipment is unreliable with the connection of earth mat, then need operation maintenance personnel to carry out detailed inspection, get rid of hidden danger.
In above-mentioned testing tool, owing to self-control plug is the simplest and the crudest, being wound around simply by insulating tape and be connected with test lead, plug cannot be changed, if plug damages, is again wound around self-control plug with insulating tape, causes test job inconvenience after the most only cutting off wire.
Summary of the invention
The purpose of this utility model is that plug is simple and crude, impracticable, plug damages the most easily changeable problem for utilizing earth-continuity tester to connect when carrying out Earthing Reliability test, it is provided that a kind of novel changeable type connecting plug, improves work efficiency.
This utility model adopts the following technical scheme that realization:
Formula connecting plug changed by a kind of earth-continuity tester, including insulation wire holder, two wiring holes are offered in described insulation wire holder front, arrange copper thread bush in described wiring hole, and described copper thread bush is connected with the test lead penetrated in wiring hole by the insulation wire holder back side；Installation irony clamping bar is screwed in described copper thread bush；Two irony clamping bars are used for being plugged in band iron edge.
During use, two irony clamping bars are screwed in by its tailing screw flight in the copper thread bush of insulation wire holder.One group of I of earth-continuity tester+Binding post and V+Binding post connects a plug, excess wire is then wound on bobbin to save space, utilize on the gap portion insertion equipment of two clamping bars on plug for the edge of ground connection band iron, or, the tapering portions of two clamping bars is contacted by hand-held plug with ground connection band iron；Another group I of earth-continuity tester-Binding post and V-Binding post connects the metal holder of tape insulation shell by test lead, is stepped up the metal part (or having identified at the ground connection band iron of the good charging equipment of ground connection) of grounded screen by clip, it is achieved conducting.During use, plug inserts in by the connection band iron of side power equipment, the resistance of this band iron is detected by earth-continuity tester, if in qualified scope, then show that this equipment and grounded screen are in the state of being reliably connected, if test resistance is beyond acceptability limit, it is likely that show that this equipment is unreliable with the connection of earth mat, then need operation maintenance personnel to carry out detailed inspection, get rid of hidden danger.
This utility model is reasonable in design, plug uses replacing formula, irony clamping bar is threaded onto in insulation wire holder by helicitic texture, after clamping bar is used for multiple times damage, making new clamping bar, insulation wire holder can reuse, simple and easy to use, and attractive in appearance, there is good practicality and market using value.

In figure, 1-junction block, 2-wiring hole, the copper thread bush of 3-, 4-test lead, 5-irony clamping bar, 6-band iron, 7-earth-continuity tester, 8-bobbin, 9-equipment, 10-pedestal, 11-earth mat, 12-bolt, 13-lever.
Detailed description of the invention
Below in conjunction with the accompanying drawings specific embodiment of the utility model is described in detail.
Formula connecting plug changed by a kind of earth-continuity tester, as shown in Figure 1, including insulation wire holder 1, two wiring holes 2 are offered in described insulation wire holder 1 front, arranging copper thread bush 3 in described wiring hole 2, described copper thread bush 3 is connected with the test lead 4 penetrated in wiring hole 2 by insulation wire holder 1 back side；Described insulation wire holder 1 back side is provided with lever 13, facilitates hand-held plug.Installation irony clamping bar 5 is screwed in described copper thread bush 3；Two irony clamping bars 5 are used for being plugged in band iron 6 edge.Two test leads 4 being passed through wiring hole are connected with the current wiring terminal on earth-continuity tester 7 and voltage wiring terminal respectively by after bobbin 8.And, it is generally the case that it is more than the irony clamping bar diameter with voltage wiring terminal UNICOM with the irony clamping bar diameter of current wiring terminal UNICOM.The diameter of irony clamping bar is tapered into its end by its root.
As in figure 2 it is shown, charging equipment 9 is reliably connected with earth mat 11 located underground by band iron 6 in transformer station.Wherein, band iron 6 is fixed on pedestal 10 by bolt 12, has certain gap between the pedestal 10 of band iron 6 and concrete.
Time specifically used, as it is shown in figure 1, the I of earth-continuity tester+Binding post and V+Binding post connects a plug, excess wire is then wound on bobbin to save space, utilize on the gap portion insertion equipment of two clamping bars on plug for the edge of ground connection band iron, or, the tapering portions of two clamping bars is contacted by hand-held plug with ground connection band iron；The I of earth-continuity tester-Binding post and V-Binding post connects the metal holder of tape insulation shell by test lead, is stepped up the metal part (or having identified at the ground connection band iron of the good charging equipment of ground connection) of grounded screen by clip, it is achieved conducting；Then test resistance.During test, it is generally required to two people cooperate to carry out, a people is reliably connected place's operation equipment in metal holder and grounded screen, and another people then holds bobbin and plug at the band iron of Devices to test, utilizes plug connection band iron and earth-continuity tester UNICOM.
Finally it should be noted that; above example is only in order to illustrate the technical solution of the utility model and unrestricted; although being described in detail with reference to this utility model embodiment; it will be understood by those within the art that; the technical solution of the utility model is modified or equivalent; without departure from the spirit and scope of the technical solution of the utility model, it all should be contained in claims of the present utility model.
