High-Voltage Switch Dynamic Characteristic Tester Performance Characteristics:
2.1, Performance
● Time: Inherent opening and closing times for 12 break contacts, same-phase synchronization, and inter-phase synchronization.
● Reclosing: For each break contact, close-open, open-close, open-close-open; values for contact touch time and dead time.
● Bounce: Closing bounce time, bounce count, bounce process, and bounce waveform for each break contact; opening amplitude for each break contact.
● Speed: Just-open and just-close speeds, maximum speed, and time-travel characteristic curves.
● Travel: Total travel, open gap, overtravel, over-travel, and amplitude.
● Current: Opening and closing coil current values, resistance values, and current waveform diagrams.
● Operating Voltage: The instrument provides a digitally adjustable DC 0-270V/20A circuit breaker operating power supply, automatically performs high and low voltage operation tests, and measures and prints the circuit breaker's operating voltage values.
2.2, Features
◆ The instrument adopts an industrial computer architecture, suitable for all models of metal contact SF6 switches, GIS combined appliances, vacuum switches, oil switches, pole-mounted switches, and contactors produced domestically and internationally.
◆ Sensors: Acceleration speed sensor, rotary speed sensor, linear travel sensor, and contact sensor, which are very easy and convenient to install.
◆ Trigger modes: Internal trigger, external trigger (2 wires for closing, 2 wires for opening), sensor trigger, and manual trigger. Manual trigger allows characteristic testing of circuit breakers operated manually (without opening/closing coils), such as manual switches on utility poles. Sensor trigger is mainly used in places with special requirements like switchgear factories.
◆ Energy storage output: The instrument can provide an adjustable DC energy storage power supply. Once the wiring is done, the motor energy storage can be controlled at any time without rewiring.
◆ The main unit features a large screen, direct-view, wide-temperature backlit LCD with electronic contrast adjustment. Complete Chinese menu prompts guide operation; after one switching action, all data and waveform diagrams are displayed.
◆ The main unit can store 1000 sets of on-site opening and closing test results, with a built-in real-time clock for archiving test dates and times; USB interface for data transfer and program upgrades.
◆ The instrument has powerful data analysis functions, capable of effectively analyzing various parameters of circuit breaker mechanical characteristics. It includes a built-in fast micro printer to print all data and diagrams.
