The staff can very easily be installed in test clamp on the switch of being tested with sounding rod on the ground, has so just saved staff's ascend operation, has reduced the danger and the working strength of ascend operation, but also has saved the plenty of time.
Since adopted technique scheme, of the present invention simple in structure, easy to make; Simple to operation in use, saved work high above the ground, reduced danger and working strength; Can practice thrift great amount of time, simultaneously, the accuracy of measurement has also had significantly raising.
In order to verify above-mentioned effect, the test that makes an experiment of the trolley type switch (wait keep in repair) of tester between tool car, the content of experimental test is that table one has provided ten empirical values of this switch to A electricity, the B accuracy of electricity, C phase electrical testing mutually mutually.
Table one
Through the empirical value in the table one comparison, absolute error is at 1.3-1.6 μ Ω, is that the test apparatus of 1 μ Ω can satisfy test request for precision.
The tester added up 35kV, 110kV switch loop resistance value, eigenwert Measuring Time from 2011 06 month to 08 month, and concrete data are shown in table two.
Table two
Can know by the contrast of the experimental data in the table two; On the averaging time of measuring loop resistance value, characteristic value; The present invention the used survey instrument required time of measurement is less than the original measurement instrument far away and measures required time; Not only avoid ascend operation, eliminated the potential safety hazard of ascending a height, but also improved work efficiency greatly.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
