The 5-Second Trick For PCB絕緣

瞬態過電壓是指在極短時間內發生的高電壓脈衝，可能持續幾微秒到幾毫秒。這些過電壓不屬於設備正常運作的工作電壓範圍，但必須被考慮進安全設計，因為它們足以擊穿絕緣或設備損壞。

依據UL1310下列條文要求，輸出接頭（output connector）不可使用同軸電纜的連接器（coaxial cable connector）。

不會。海拔高度只會影響空氣的介電強度，因此只會調整「間隙距離」；爬電距離設計不受高度影響。

因此，選擇適當的爬電距離對於減少電氣故障風險至關重要。所需距離取決於電壓水平、絕緣材料類型以及運行環境條件。通過確保組件符合爬電標準，設計人員可顯著提升電氣系統的安全性與可靠性，尤其在高壓應用中。

不行。兩者是獨立的安全設計參數，爬電距離用於防止表面漏電，間隙距離則防止空氣放電。缺一不可，需分別依標準查表計算。

若設計人員未能清楚區分這兩項距離，可能導致誤判風險來源，進而影響產品安全性與安規通過率。

設備運行環境中的污染狀況會顯著影響絕緣性能。污染等級越高，越容易在絕緣表面形成導電通路，增加漏電或電弧風險，因此需設定更長的爬電距離。

不同的絕緣措施(如基本絕緣、雙重絕緣或強化絕緣)對爬電距離的要求有所不同，越高等級的絕緣保護，所需距離越長。
