The KDGK-F switch mechanical characteristic tester can accurately measure the mechanical dynamic characteristic parameters of various voltage levels of high voltage circuit breakers such as low oil, high oil, vacuum, and sulfur hexafluoride.

The measurement data is stable, the wiring is convenient, and the operation is simple. It is a commonly used tool for high-voltage switch maintenance and testing.

1. The instrument can automatically identify the opening and closing status of the fracture, and prompt the corresponding closing and opening operations based on the reference fracture status.
2. The independent 6-section can detect and indicate the connection status of the fracture, making it convenient for users to check the wiring.
3. The machine can store 100 sets of test results.
4. Large screen LCD (320 × 240) display, advanced gray screen, non reflective and non black screen under sunlight, graphic and Chinese menu operation prompts, user-friendly menu interface, easy to operate.
5. The instrument has graphic analysis function, which enables waveform and measurement processing data to be displayed on the same screen, making the testing process more intuitive.
6. The machine is equipped with a delay protection function, which can automatically cut off the coil voltage after the circuit breaker is activated, effectively protecting the circuit breaker and testing instruments.
7. This instrument can perform both electric and manual opening and closing tests.
8. High and low voltage experiments can be conducted to automatically find the lowest opening or closing voltage.
9. The reclosing test can be used to measure parameters such as closing, opening, and closing.
10. Integrated operation power supply inside the machine, no need for on-site secondary power supply, convenient and fast on-site use. Can provide adjustable power supply of DC20-265V with a current of 20A. It can set the operating voltage values of the opening and closing coils, and can also perform low voltage operation tests on circuit breakers.
11. Equipped with linear sensors, rotation sensors, universal sensors, brackets, and dedicated fixed multifunctional joints, easy and simple to install.
12. Suitable for most models of SF6 switches, GIS combination devices, vacuum switches, and oil switches.
13. The internal anti-interference circuit can meet the reliable use in a 500KV substation.
14. Can test the opening speed, closing speed, closing time, opening time, closing time, different closing periods, different opening periods, bounce time, opening coil starting voltage test, opening and closing starting current, etc.
