Isolating switch defect processing is diagnosed: can measure the segmentation of isolating switch different parts, by the comparative analysis to different parts contact resistance, for fault diagnosis provides foundation;
Reduce the outside destroy to tested device in process of the test;
Prevent because loose contact etc. causes loss to increase, heating damages tested device.
Improve work on the spot efficiency.
The key technical indexes is as follows:
Measurement range: 1 ~ 1999 μ Ω;
Resolution: 1 μ Ω;
Measuring current: DC 100A.
The present invention is applicable to the measuring contact resistance of electric power, the on-the-spot high-voltage switch gear of power supply department, is particularly useful for the measurement of all types of ring main unit, and can to tested device areal survey, for fault diagnosis provides foundation.Play a great role in real work application, there is good application prospect.
