HVKC-II High Voltage Switch Mechanical Characteristics Tester
I. Features and Main Functions
1. 320×240 super large blue screen LCD display, high-speed thermal printer;
2. Integrated operating power supply, no need for on-site secondary power supply, making on-site use more convenient and faster;
3. With waveform recording function, it can display the contact state waveform, opening (closing) coil current waveform, and travel-time (S-t) curve corresponding to the time coordinate, which is conducive to accurate judgment of switch mechanism faults;
4. Can test 6 channels of time and synchronization, bounce;
5. Can test one speed, equipped with slide wire resistor (rotation angle, straight line), covering almost all types of switch speed tests;
6. Internal anti-interference circuit can withstand 15kV high voltage induced on site, protecting the contact safety and reliability;
7. Support low voltage test of switch operating mechanism;
8. Touch screen operation, no keyboard required.
