Abstract
The utility model discloses a ground resistance test wire clamp, which belongs to the technical field of power system test equipment, and comprises a metal pothook, a conducting wire and an insulating rod, wherein the metal pothook is fixedly arranged on the insulating rod; and an exposed metal wire core on the end part of the conducting wire is fixedly connected with the metal pothook. Firstly, the metal pothook is hooked on a wire to be tested, the wire core on the lower end of the conducting wire is connected with an ohmmeter, the ohmmeter can be used for directly testing wire resistance of the wire to be tested, the testing is convenient, and the operation is simple; secondly, the wire clamp comprises the insulating rod with a certain length, so that a worker can test the wire resistance without climbing up and down a rod tower, and the testing time is shorter; and finally, the wire clamp is formed by assembling a plurality of devices, and not all the devices need to be replaced when one device is damaged, so that the maintenance cost is reduced.
Description
Technical field
The utility model belongs to electric system testing apparatus technical field, relates in particular to a kind of test wires stake resistance and uses wire clamp.
Background technology
When transmission line of electricity generation earth fault,, adopt the method for the switchgear sectionalization test stake resistance on the open-circuit line to come the localization of faults for finding out failure cause fast more.When testing, often need personnel on electric pole, to carry out earth resistance; There are a lot of unsafe factors in the operating personnel on the bar when carrying out resistance test; Going up simultaneously lower beam needs the time, has increased the time of finding out failure cause, for staff's p-wire stopband has come great inconvenience.
The utility model content
The utility model technical matters to be solved provides a kind of earth resistance wire clamp, has the advantages that the resistance of test wires line is convenient and the test duration is short.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of earth resistance wire clamp; It is characterized in that comprising metal hanger, lead and insulating bar; Said metal hanger is fixed on the said insulating bar, and the bare metal core of said wire termination is fixedly connected with said metal hanger.
The bare metal core of said wire termination is connected with said metal hanger with screw through packing ring, and said packing ring and said screw are suitable.
Said metal hanger is fixedly connected through the insulating bar attachment cap with said insulating bar.
Said wire clamp also comprises baffle plate, and an end of said baffle plate is fixed on the said metal hanger through said packing ring and said screw, and said baffle plate is positioned at the opening of said metal hanger and keeps being obliquely installed.
Said metal hanger is connected with said insulating bar attachment cap through connecting link.
Said metal hanger and said connecting link are through being threaded.
Be fixedly connected with backstay on the connecting link of said metal hanger open lower end.
Said wire clamp also comprises wire-wrap board.
Adopt the beneficial effect that technique scheme produced to be: at first; Said metal hanger is hung on the test line, the core of said lead lower end is connected with ohmmeter, ohmmeter just can directly test out the line resistance of test line; Convenient test, simple to operate; Secondly, said wire clamp comprises the insulating bar with certain-length, need not the staff up and down shaft tower come the p-wire resistance, the test duration is shorter; At last, said wire clamp is assembled by a plurality of devices, when wherein some device failure, need not to change all devices, has reduced maintenance cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
