GDKC-15A Circuit Breaker Analyzer
Product Description
High voltage circuit breaker is one of the most important control equipment in the power system. GDKC-15A is used to test the dynamic characteristics of high voltage circuit breaker. It is easy to operate, with high accuracy.
Features
- It is suitable for the mechanical test of all types of SF6 switches, GIS combination appliances, vacuum switches and oil switches.
- Strong anti-interference ability. It can be easily tested and accurately measured in 500kV substation.
- Accelerometer (optional), linear sensor, rotary sensor, easy to install and simple.
- When the switch is actuated once, all the data of the switch mechanical characteristic test and the corresponding waveform map are obtained.
- Store the field test data and built-in real time clock, which is convenient for archiving and saving the test date and time.
- With 8inch LCD screen, display all data and map, with background light, LCD contrast adjustment and power off memory.
- Friendly menu operation, easy to use. With built-in printer to quickly print all data results.
- Equipped with data analysis management software, which can be operated online with PC, with WORD format file. The test results can be output to all kinds of printers printing test reports to make the field test computerized.
- Combined speed selection and user-defined function set according to needs, suitable for the speed measurement of any type of switches.
