With the development of society, people have higher and higher requirements for the safety and reliability of electricity use. High-voltage circuit breakers are responsible for the dual tasks of control and protection in the power system, and their performance is directly related to the safe operation of the power system. The mechanical characteristic parameter is one of the important parameters to judge the performance of the circuit breaker. The high-voltage switch comprehensive characteristic tester (high-voltage switch mechanical characteristic tester) is based on the latest "High-voltage AC Circuit Breaker" GB1984-2003 as the design blueprint, and refers to the third of the People’s Republic of China Electric Power Industry Standard "General Technical Requirements for High-Voltage Test Equipment" Part, DL/T846.3-2004 is the design basis, which provides convenience for the dynamic analysis of various circuit breakers, and can accurately measure various voltage levels of low-oil, high-oil, vacuum, sulfur hexafluoride and other high-voltage circuit breakers. The mechanical dynamic characteristic parameters of the device. High-voltage circuit breakers are responsible for the dual tasks of control and protection in the power system, and their performance is directly related to the safe operation of the power system. The mechanical characteristic parameter is one of the important parameters for judging the performance of the circuit breaker. The instrument mainly has the following characteristics:
 

⑴ This instrument is an embedded industrial computer, the main board is based on CortexTM-A8, the main frequency is 1GHZ, the flash memory is 1GB, and the boot speed is only 16 seconds. 8.4-inch color large screen, windows operating system, intuitive user-friendly operation interface, touch screen, support Chinese and English input, easy for on-site operators to use.
 

⑵. It has the ability to test under conventional wiring and double-ended grounding wiring, which can test the time characteristics, speed characteristics, stroke test, auxiliary switch action time, coil current characteristics, energy storage motor current characteristics, and closing resistance tests of the circuit breaker. Functions such as dynamic resistance test and buffer test.
 

⑶. With the circuit breaker live measurement function, through the circuit breaker opening (or closing) coil current, voltage, armature action time, closing stroke curve; opening stroke curve; closing-opening stroke curve; opening-closing-opening stroke Curve; coil current curve; coil voltage curve; motor energy storage curve; time curve and other waveform curve graph analysis, to diagnose the state of the circuit breaker operating mechanism, such as: mechanism jam, grease solidification and condensation, opening/closing coil status , Auxiliary point failure, battery stability, closing (opening) time, three-phase different period, etc.
