Darui Electric recommends
Product Performance
• Time: Inherent opening and closing time of 12 contacts, simultaneity within same phase and between phases.
• Reclosing: Close-Open, Open-Close, Open-Close-Open for each contact; value of metal short time and currentless interval time.
• Bounce: Closing bounce time, bounce count, bounce process, bounce waveform for each contact; opening rebound amplitude for each contact.
• Speed: Speed at opening and closing instant, maximum speed, time-travel characteristic curve.
• Travel: Total travel, open gap, overtravel, overshoot travel, rebound amplitude.
• Current: Opening and closing coil current value, current waveform.
• Operating Voltage: Built-in DC 0～270V/20A digitally adjustable circuit breaker operating power supply, automatically completes high and low voltage operation test, measures and prints the operating voltage value of the circuit breaker.
Product Applications |
• The instrument adopts industrial computer architecture, suitable for all models of metal contact SF6 switches, GIS composite appliances, vacuum switches, oil switches, pole-mounted switches, contactors, etc. produced domestically and internationally.
• Sensors: Acceleration speed sensor, rotary speed sensor, linear travel sensor, and contact sensor, extremely easy and simple to install.
• Triggering Modes: Internal trigger, external trigger (2 for closing, 2 for opening), sensor trigger, and manual trigger. Manual trigger can perform characteristic tests on circuit breakers operated manually (without opening/closing coils), such as manual opening/closing switches on utility poles. Sensor trigger is mainly used in switchgear factories and other special requirements.
• Energy Storage Output: The instrument can provide DC adjustable energy storage power supply. Once the wiring is done, there is no need to rewire to control motor energy storage at any time.
• 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 operation, all data and waveform graphs are displayed.
• The main unit can store 1000 sets of on-site opening and closing test results. Built-in real-time clock facilitates archiving of test dates and times; USB interface for data transfer and program upgrade.
• The instrument has powerful data analysis functions, capable of effectively analyzing various parameters of circuit breaker mechanical characteristics. Built-in fast micro printer prints all data and graphs.
