6 FAQs about [Arc extinguishing device battery]
What is arc blowing & arc extinguishing?
Both arc-blowing methods aim to blow the charged particles away from the arc area, reducing the charged particles in the arc gap and thus speeding up the arc-extinguishing process. In addition, the high-speed airflow improves the convective heat transfer, increasing cooling and enhancing the arc-extinguishing effect.
What is the difference between ARC Building and extinguishing?
The arc building process exhibits a strong linear correlation, while the extinguishing process is slightly less correlated and the data is more scattered. This discrepancy is due to the almost chaotic and very complicated extinguishing process during which the arc is extended and fluctuating within the chamber.
Does arc extinguishing cause stress?
A clearly positive, strong linear correlation with a correlation parameter of r = 0.9 is observed for the total arcing and arc extinguishing processes (shown in red and green). The slower the arc extinguishes, the more energy is released during this time, which in turn means more stress for the HVC.
Can a DC arc be extinguished?
As stated above, there is no zero-crossing of voltage and current in a DC circuit to help extinguish possible arcs. Therefore, the current must be forced to zero by extraordinary Only when Uarc is larger than UDC, the time dependent current I can be forced to zero and the arc can be extinguished.
Do ESC protection devices arc-extinguish?
The effectiveness and limitations of weak links for protection in external short circuits of battery modules are verified. A quantitative analysis method for the response time of the ESC protection device is proposed. The arc-extinguishing capabilities of the ESC protection devices for battery modules with different voltage are verified.
What are the different arc extinguishing methods?
