GDGK-303 Hot Circuit Breaker Analyzer for All Kinds of Switches

GDGK-303 Hot Circuit Breaker Analyzer for All kinds of Switches
1.1 Introduction
GDGK-303 Dynamic Characteristics of High-Voltage Switch Tester 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.
1.2 Major Testing Items and Functions
1 Measure opening time and closing time of 12 interfaces of GIS
2 Measure opening time and closing time of continuous on and off of GIS
3 Test the synchronization performance
4 Measure speed at instant of GIS on and GIS off.
5 Measure springing time and springing magnitude
6 Measure the distance from GIS off to the point on which the two contacts touch each other instantly.
7 Measure the distance from the point on which the two contacts touch each other instant to the point on which two contacts stop moving.
8 Measure the average speed of GIS off and GIS on.
9 Display and print the speed-time curve, the distance-time curve and the speed-distance curve.
