Kebergantungan tempoh arka D dan jurang sentuhan pada kepupusan arka d pada kelajuan buka kenalan v dikaji untuk arka putus yang dijana dalam litar perintang 48VDC pada kelajuan buka sentuhan tetap. Kelajuan pembukaan v dipelbagaikan dalam julat luas dari 0.05 hingga 0.5m/s. Arus litar semasa sesentuh elektrik ditutup I0 dipelbagaikan kepada 10A, 20A, 50A, 100A, 200A, dan 300A. Keputusan berikut diperolehi. Untuk setiap arus I0, tempoh arka D berkurangan dengan peningkatan kelajuan pembukaan sesentuh v. Walau bagaimanapun D at I0=300A adalah lebih pendek daripada itu pada I0=200A. Sebaliknya, jurang hubungan pada kepupusan arka d cenderung meningkat dengan peningkatan I0. Walau bagaimanapun d at I0=300A adalah lebih pendek daripada itu pada I0=200A. The d hampir berterusan dengan peningkatan v untuk setiap arus I0 apabila I0 adalah lebih rendah daripada 200A. Walau bagaimanapun d menjadi lebih pendek apabila v adalah lebih perlahan pada I0=200A dan 300A. Dekat v=0.05m/s, contohnya, d at I0=300A adalah lebih pendek daripada itu pada I0=100A. Untuk menjelaskan punca keputusan d, sebagai tambahan, panjang lengkok sejurus sebelum kepupusan L telah dianalisis. The L cenderung meningkat dengan peningkatan arus I0. Yang L hampir berterusan dengan peningkatan v apabila I0 adalah lebih rendah daripada 200A. Namun, apabila I0=200A dan 300A, iaitu L cenderung menjadi lebih panjang apabila v adalah lebih perlahan. Ciri-ciri yang d akan dibincangkan menggunakan hasil analisis daripada L dan gerakan lengkok pecah. Pada arus yang lebih tinggi di I0=200A dan 300A, lebih pendek d paling lambat v disebabkan oleh gerakan luas bintik-bintik arka pada permukaan sentuhan dan ubah bentuk lengkok pecah yang lebih besar.

Abstract: Dependences of arc duration D and contact gap at arc extinction d on contact opening speed v are studied for break arcs generated in a 48VDC resistive circuit at constant contact opening speeds. The opening speed v is varied over a wide range from 0.05 to 0.5m/s. Circuit current while electrical contacts are closed I0 is varied to 10A, 20A, 50A, 100A, 200A, and 300A. The following results were obtained. For each current I0, the arc duration D decreased with increasing contact opening speed v. However, the D at I0=300A was shorter than that at I0=200A. On the other hand, the contact gap at arc extinction d tended to increase with increasing the I0. However, the d at I0=300A was shorter than that at I0=200A. The d was almost constant with increasing the v for each current I0 when the I0 was lower than 200A. However, the d became shorter when the v was slower at I0=200A and 300A. At the v=0.05m/s, for example, the d at I0=300A was shorter than that at I0=100A. To explain the cause of the results of the d, in addition, arc length just before extinction L were analyzed. The L tended to increase with increasing current I0. The L was almost constant with increasing the v when the I0 was lower than 200A. However, when I0=200A and 300A, the L tended to become longer when the v was slower. The characteristics of the d will be discussed using the analyzed results of the L and motion of break arcs. At higher currents at I0=200A and 300A, the shorter d at the slowest v was caused by wide motion of the arc spots on contact surfaces and larger deformation of break arcs.
