Workflow
FAQ
-
1. What should be done if the contactor gets "stuck" and the current cannot be cut off?This is a common safety hazard existing in the high current test. To address this, the equipment adopts a dual physical disconnection protection mechanism: in addition to the main contactor, an emergency safety air switch or physical fuse device is also configured; in case of abnormal conditions, forced power-off can be achieved through the secondary circuit, effectively avoiding the risk of fire caused by continuous overheating.
-
2. How does the equipment capture the instantaneous peak value of short-circuit current?The current during a short circuit changes extremely rapidly (at the millisecond level). Therefore, the equipment adopts a high sampling rate data acquisition module (100kHz and above) combined with high-precision current sensors (such as Rogowski coils, high-frequency shunts, etc.), which can completely capture and record the instantaneous current waveform, ensuring the authenticity and completeness of the test data.
-
3. Can different voltages be tested?Yes. The equipment supports a wide range of voltage levels from DC5V to DC1500V. All you need to do is set the corresponding protection threshold in the software interface, thus truly achieving multi-purpose use with a single machine.
-
4. What standards does the short-circuit test equipment comply with?The equipment is designed to meet major international and domestic battery safety testing standards, including UN38.3, IEC 62133, UL 2580, GB 31241, GB/T 31485, and GB/T 31467.3, making it suitable for certification testing across global markets.
-
5. Is the equipment suitable for both laboratory and production line use?Yes. The system supports remote computer control and video surveillance, making it adaptable for both R&D laboratory environments and production line quality inspection scenarios. Customizable current range (DC5000A–DC20000A) and explosion-proof enclosure options ensure it meets diverse deployment needs.
-
6. Can the resistance value of the short-circuit device be adjusted?Yes. The 2nd type contactor configuration supports an adjustable internal resistance range of 1mΩ to 100mΩ or higher (optional), enabling simulation of various real-world short-circuit conditions. The constantan resistance material ensures a low temperature coefficient (≤50ppm/℃), guaranteeing stable and repeatable test results.
