II. Performance & Features
1. Core Testing Capabilities
* Timing: Precisely measures up to 12 critical timing points including contact make/break times, close/open durations, and contact synchronization.
* Reclosing: Tests complex sequences (O-C, C-O, C-O-C-O), measuring sequence times and durations.
* Speed: Measures contact closing speed, opening speed, maximum speed, and generates time-stroke characteristic curves.
* Travel: Measures total travel, contact gap (open distance), overtravel, overshoot travel, and rebound amplitude.
* Current: Measures and records opening and closing coil current values and waveforms.
* Operating Voltage Test: Provides a digitally adjustable DC power supply (30-250V/10A) for breaker operation. Automates low-voltage operation tests and measures the actual operating voltage requirement of the breaker.
2. Key Features & Advantages
* Wide Compatibility: Suitable for mechanical characteristic testing of various circuit breakers (CBs), including SF6, GIS, vacuum, and oil types from domestic and international manufacturers.
* Robust EMC Performance: Excellent noise immunity, proven reliable for accurate measurements even in challenging environments like live 500kV substation bays.
* Versatile Sensor Support: Accommodates multiple sensor types (universal speed, linear displacement, rotary encoder) with simple, flexible installation.
* Comprehensive Data Capture: Acquires all mechanical characteristic data and corresponding waveforms in a single switching operation.
* Onboard Data Storage & Management: Stores test data internally with real-time clock stamping for easy archiving by date and time.
* Large, High-Contrast Display: Features a wide-temperature, direct-view, backlit LCD displaying all data and graphs in Chinese. Electronic contrast adjustment and power/memory indicators included.
* Intuitive Operation & Printing: User-friendly Chinese menu interface. Integrated printer allows immediate hardcopy output of all test data and graphs.
* PC Software Suite: Includes data analysis and management software for PC connectivity. Enables report generation via various printers (dot-matrix, laser, inkjet) and facilitates computerized field testing.
