Product functions
1. Opening/closing time testing
Enables synchronous measurement of the opening time, closing time, and operation time difference between interrupters of the circuit breaker, and analyzes three-phase synchronization and operation consistency between interrupters, helping users accurately assess the operating performance of the circuit breaker's opening/closing mechanism.
2. Speed and travel testing
Collects motion data during circuit breaker operation through speed sensors. It can measure key parameters such as opening speed, closing speed, just-opening speed, just-closing speed, and operating travel, and generate corresponding speed and travel characteristic curves, providing reliable data for circuit breaker mechanical performance testing and mechanism adjustment.
3. Bounce characteristic testing
Detects the bounce phenomenon of contacts during circuit breaker closing, measures bounce time, bounce count, and related waveforms, and intuitively reflects the contact closing process through test curves, helping to analyze the operating condition of circuit breaker contacts and operating mechanism.
4. Opening/closing coil current testing
Enables synchronous acquisition of the operating current of the circuit breaker's opening coil and closing coil, recording the complete current variation process and waveforms. By analyzing coil current characteristics, it assists in determining the working condition of the operating coil and circuit breaker control circuit, providing reference for equipment fault diagnosis and maintenance.
5. Dynamic resistance testing
Supports circuit breaker dynamic resistance testing, recording dynamic resistance changes and waveforms during contact movement. This function is particularly suitable for Siemens graphite contact switches, enabling dynamic resistance waveform testing on related interrupters.
6. Reclosing characteristic testing
Supports characteristic testing of the circuit breaker reclosing process. Parameters such as reclosing interval time, metal short-circuit time, and dead time can be set according to test requirements, enabling detection of the circuit breaker reclosing operation process and providing test data for reclosing performance analysis.
