1.1 General introduction

GDGK-306  H.V Circuit Breaker Tester is special instrument for power system GIS mechanical properties measuring.

GDGK-306  H.V Circuit Breaker Tester 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,

GDGK-306  H.V Circuit Breaker Tester is applicable to all 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 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

10 Display and print the speed-time curve, the distance-time curve ,the speed-distance curve and the current-time curve.
