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; contact time and dead time values.
● Bounce: Closing bounce time, bounce count, bounce process, bounce waveform for each break contact; opening amplitude for each break contact.
● Speed: Just-open and just-close speeds, maximum speed, time-travel characteristic curve.
● Travel: Total travel, open distance, overtravel, over-travel, amplitude.
● Current: Opening and closing coil current values, resistance values, and current waveform diagrams.
● Operating Voltage: Built-in DC 0-270V/20A digitally adjustable circuit breaker operating power supply, automatically performs high and low voltage operation tests, 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, and pole-mounted switches, contactors, etc., produced domestically and internationally.
◆ Sensors: Acceleration speed sensor, rotary speed sensor, linear travel sensor, and contact sensor, making installation extremely convenient and simple.
◆ 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 poles. Sensor trigger is mainly used in places with special requirements like switch factories.
◆ Energy storage output: The instrument can provide a DC adjustable energy storage power supply; once connected, it can control motor energy storage at any time without rewiring.
◆ The host has a large screen, direct-transmissive, wide-temperature backlit LCD with electronic contrast adjustment. Complete Chinese menu prompts guide operation; after one switch operation, all data and waveform diagrams are displayed.
◆ The host can store 1000 sets of on-site opening and closing test results, with a built-in real-time clock for easy archiving of test dates and times; USB interface for data transfer and program upgrades.
◆ The instrument has powerful data analysis functions, capable of effectively analyzing various performance parameters of circuit breaker mechanical characteristics. Built-in fast micro printer prints all data and diagrams.
