尊敬的用戶您好！"VHP真空斷路器12-40.5"是一種高壓電器設備，其中"VHP"通常代表 Vacuum High Pressure，即真空高壓斷路器。這種類型的斷路器主要用于電力系統(tǒng)中，它采用真空作為滅弧介質(zhì)，在操作過程中能夠迅速并有效地開斷和閉合電路，確保在高壓電條件下安全、可靠地切斷或接通電流。 具體到 "12-40.5" 這一型號參數(shù)，"12" 表示該斷路器的額定電壓范圍為12kV（千伏），而 "40.5" 則表示其額定短路開斷電流能力達到了40.5kA（千安）。這意味著這款VHP真空斷路器適用于交流12kV電網(wǎng)系統(tǒng)，能夠承受較高的短路電流沖擊，確保電力系統(tǒng)的正常運行及故障保護需求。如有更多關于此類產(chǎn)品的問題或需要詳細的技術參數(shù)，請隨時咨詢我們。
