34 and 35: Connect the energy-storing motor effectively

Product testing

Comprehensive Mechanical Operation Test:

Meticulously scrutinize the mechanical operation of the circuit breaker to ensure it is exceptionally flexible, unwaveringly dependable, and consistently reliable.Test the seamless operation functions, including

closing, opening, and the impeccable precision of energy storage systems. Electrical Performance Testing Excellence: Setting New StandardsConduct a meticulous insulation resistance test by employing a megohmmeter to measure the insulation resistance of both main and auxiliary circuits, ensuring they surpass standard requirements (typically ≥ 1M Ω).

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

Conduct the 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: Ensuring Unmatched Safety

Evaluate the precision of action values and the timing of protection functions such as

overload and short circuit,

as well as ground fault scenarios. Ensure the meticulous calibration and flawlessoperability of the industry-leading intelligent release device.
