Product testing

Comprehensive Mechanical Operation Test:

Meticulously scrutinize the mechanical operation of the circuit breaker to ensure it is supremely flexible and unwaveringly reliable.Thoroughly test the seamless operation functions such as

closing ,opening , and the precision ofenergy storage. Electrical Performance Testing Excellence:Conduct a detailed insulation resistance test: Employ a high-precision megohmmeter to measure the insulation resistance of both main and auxiliary circuits, ensuring they not only meet but exceed standard requirements (typically ≥ 1M Ω).

Power Frequency Withstand Voltage Test: Administer the rated power frequency voltage (e.g., 2500V/1min) to both the main and auxiliary circuits, thoroughly assessing the robustness of insulation performance.

Contact Resistance Test: Meticulously gauge the contact resistance of the primary contact to confirm it remains beneath the established threshold (commonly at a micro ohm level).

Protection Function Test Mastery:

Expertly evaluate the action values and timing of protection functions such as

overload, short circuit

, and ground fault. Ensure the precise calibrationand seamless operability

of the state-of-the-art intelligent release device.
