1.1 General
introduction
The GDGK***6 is special instrument for power system GIS
mechanical properties measuring. The instrument takes ARM7 for the
core to process the test data. With high intelligence, lots of
functions, accurate test data, strong anti-jamming, easy operation,
small size, light weight and so on, It is applicable to kinds of
GIS mechanical properties measuring such as indoors or outdoors
switches with less oil or more oil, vacuum switches, sulfur
hexafluoride switches and so on.
1.2Major testing items and functions
1 Measure opening time and closing time of *2 interfaces
of GIS
2 Measure opening time and closing time of continuous on
and off of GIS
3 Test the synchronization performance
4 Measure bounce time and bounce times of vacuum
switches
5 Measure the distance from GIS off to the point on
which the two contacts touch each other instantly.
6 Measure the distance from the point on which the two
contacts touch each other instant to the point on which two
contacts stop moving.
7 Measure speed at instant of GIS on and GIS off.
8 Measure the maximum speed of GIS on and GIS off
9 Measure the average speed of GIS on and GIS off
*0 Display and print the speed-time curve, the distance-time
curve ,the speed-distance curve and the current-time curve.
