With the development of society, people have higher and higher requirements for the safety and reliability of electricity. High-voltage circuit breakers are responsible for the dual tasks of control and protection in power systems, and their performance is directly related to the safe operation of the power system. Mechanical characteristic parameters are one of the important parameters for judging the performance of circuit breakers.
Our company's GDGK-307 Circuit breaker analyzer can accurately measure the mechanical dynamic characteristic parameters of oil-less, high-oil, vacuum, SF6 and other high-voltage circuit breakers of various voltage levels.
Advantages
---GDGK-307 High Voltage Switch Circuit Breaker Analyzer with Dual Ground
3 channels of dual ground(6 channels can be customization): The mechanical characteristics of GIS composite appliances and high-voltage circuit breakers can be measured without opening the grounding switch of the ultra-high voltage switchgear.
12 channels of time measurement input channels, three of which support resistance contacts and time contacts at the same time, 6 channels of completely isolated fracture input, which can detect 4-level series fractures at the same time.
Embedded computer
GDGK-307 Circuit Breaker Analyzer integrates the 100A contact resistance tester function to help customers reduce repeated investment.
Automatic evaluation of circuit breaker status based on test results.
It can automatically generate word documents to facilitate customers' data analysis.
You can also control our GDGK-307 Circuit Breaker Analyzer by your computer(need customization).
