The KDGK-F circuit breaker mechanical characteristic tester is based on the design of "High Voltage AC Circuit Breakers" GB1984-2003 and refers to the design basis of the "General Technical Conditions for High Voltage Test Equipment" Part 3, DL/T846.3-2004 of the People's Republic of China Electric Power Industry standard, providing convenience for dynamic analysis of various circuit breakers. It can accurately measure the mechanical and dynamic characteristic parameters of high-voltage circuit breakers of various voltage levels, such as low-oil, multi-oil, vacuum, and sulfur hexafluoride. High-voltage circuit breakers undertake the dual tasks of control and protection in power systems, and their performance is directly related to the safe operation of power systems. Mechanical characteristic parameters are one of the important parameters for judging the performance of circuit breakers.

Product performance characteristics
Performance:
Time: The inherent opening and closing times of the 12 breaks, the same phase and the same period between phases.
Reclosing: The process time of each break - opening, opening - closing, opening - closing - opening: first opening time, first closing time, second closing time, gold short time, no current time value.
Bounce: The closing bounce time of each break, the number of bounces, the bounce process, and the bounce waveform; The rebound amplitude of the opening at each break.
Speed: Just-split and just-closed speed, maximum speed, time-stroke characteristic curve.
Travel: Total travel, opening distance, over-travel, overshoot travel, rebound amplitude.
Current: The opening and closing current values of the opening and closing coils, and the current waveform diagram.
Operating voltage: The machine provides a DC30 ~ 250V/20A digital adjustable circuit breaker operating power supply inside, automatically completing the low-voltage operating test of the circuit breaker and measuring the operating voltage value of the circuit breaker.
 
Features:
one It is applicable to the mechanical characteristic tests of various SF6 switches, GIS combined electrical apparatus, vacuum switches and oil switches produced at home and abroad.
2 It has an extremely strong anti-interference ability, allowing for easy testing and precise measurement even when the bypass busbar of a 500KV substation is energized.
3 Universal speed sensor, linear sensor, rotary sensor, easy and simple to install.
4. Once the switch operates, all the data of the mechanical characteristic test of the switch and the corresponding waveform diagrams are obtained.
5 The main unit can store on-site test data and has a real-time clock inside, which is convenient for archiving and saving the test date and time.
6. The main unit features a large screen, wide temperature range, direct transparency, backlit LCD, and full Chinese display of all data and spectra. The LCD contrast is electronically adjustable and power-off memory is available.
7. The Chinese menu operation is convenient to use. The instrument is equipped with a built-in printer, which can quickly print all data and spectra at any time.
