The 2-Minute Rule 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。

爬電距離的選擇以日常運行時的額定工作電壓為依據,工作電壓越高,對絕緣的需求越大,所需爬電距離也越長。

.介質不同:間隙距離依賴空氣的絕緣能力,而爬電距離取決於固體絕緣材料表面的性能。
