Product testing

Comprehensive Mechanical Operation Test:

Scrutinize the mechanical operation of the circuit breaker to ensure it is supremely flexible and unwaveringly reliable.Test the seamless operation functions such as

closing ,opening , and the precision ofenergy storage. Electrical Performance Testing Excellence:Conduct an insulation resistance test: Employ a megohmmeter to measure the insulation resistance of both main and auxiliary circuits, guaranteeing they surpass standard requirements (typically ≥ 1M Ω).

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

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

Protection Function Test Mastery:

Evaluate the action values and timing of protection functions such as

overload, short circuit

, and ground fault. Assure the calibrationand operability

of the cutting-edge intelligent release device.
