1. Core functions
The switch characteristic tester is used to accurately measure the key dynamic and static characteristic parameters of electrical switches (such as circuit breakers, relays, isolating switches, etc.), including:
Action time: opening/closing time, jumping time.
Action speed: Contact movement speed and stroke curve.
Contact performance: Contact resistance, circuit resistance.
Synchronization: Synchronization error of multi contact switches.
2. Application Fields
Power system: Detect the opening and closing characteristics of high-voltage circuit breakers and GIS equipment to ensure the safe operation of the power grid.
Rail Transit: Testing the reliability of locomotive traction systems and signal control switches.
Electronic manufacturing: Verify the lifespan and operational accuracy of relays and micro switches.
Automotive industry: Evaluate the response performance of automotive relays and Battery Management System (BMS) switches.
3. Technical advantages
High precision measurement: supports μ s level time resolution and μ Ω level resistance measurement, meeting rigorous testing requirements.
Automated testing: Built in program can complete multi parameter acquisition with one click, supporting waveform display and data storage.
Portability and compatibility: Suitable for different voltage levels (such as 10 kV~550 kV) and switch types, suitable for laboratory or on-site testing.
4. Industry standard support
Compliant with international and national standards such as IEC 62271-100 and GB/T 1984, ensuring the authority of test results.
5. Actual application value
Fault diagnosis: Quickly locate mechanical jamming, poor contact and other defects of the switch to reduce power outage losses.
Quality control: Optimize production processes to improve the lifespan and reliability of switchgear.
Preventive maintenance: Through regular testing, predict equipment aging trends and reduce operation and maintenance costs.
6. Typical testing scenarios
Circuit breaker maintenance: Verify the operating voltage and mechanical characteristic curve of the opening and closing coils.
Relay life test: Performance degradation analysis after simulating 10000 operations.
New energy equipment testing: dynamic response verification of photovoltaic inverters and energy storage system switches.
