Testing principle:
The high-voltage switch mechanical characteristic tester adopts the four terminal wiring method of circuit resistance testing, which actually tests the dynamic resistance during the switch action process and can be used to test SF6 high-voltage circuit breakers with graphite contacts The working principle of the dynamic resistance testing channel is to load a 10A constant current source on the two terminals of the graphite contact of the circuit breaker. Through the other two test signal lines (voltage signals) connected to both ends of the circuit breaker, the dynamic voltage change waveform within 200mV during the action of the graphite contact is tested to determine the position of the metal contact of the circuit breaker. Then, based on the length of the graphite contact, the true and accurate position of the graphite contact can be inferred

Product Features:
(1) Can be operated electrically or manually;
(2) Mechanical dynamic characteristic testing of various high-voltage circuit breakers suitable for voltage levels up to 500KV;
(3) Can measure and customize travel itineraries;
(4) Capable of performing single closing, single opening, closing/opening, reclosing, and re opening operations on circuit breakers;
(5) Easy to connect, simple to operate, only one closing (opening) action is needed to obtain all closing (opening) data. You can choose to save 50 sets of data, provide later query and upload to the computer for long-term storage, and also access and print all data and motion curve graphs on site;
(6) Using Chinese character prompts to operate through human-machine dialogue;
(7) Accurate data, strong anti-interference ability, small size, light weight, and beautiful appearance;
(8) The machine is equipped with a clock circuit that can display the current year, month, day, hour, minute, and second. Even if there is a power outage, it can automatically save the set data and test data;
(9) The machine is equipped with a delay protection function, which can automatically cut off the power supply after the circuit breaker is activated, effectively protecting the circuit breaker equipment and high-voltage switch tester
