標準解讀
《GB/T 7357-2025 船舶電氣設備 系統設計 保護》相較于《GB/T 7357-2010 船舶電氣設備 系統設計 保護》，在多個方面進行了更新和調整，以適應技術進步及行業需求的變化。新版本標準更加強調了電氣系統安全性與可靠性的要求，并引入了新技術的應用指導。
首先，在術語定義部分增加了對一些新出現的電氣元件和技術名詞的解釋，確保文檔能夠準確反映當前行業狀況。其次，對于電氣設備的選擇、安裝以及維護提出了更加具體且嚴格的要求，尤其是在防止電氣火災、提高能效等方面做了詳細規定。
此外，《GB/T 7357-2025》還特別關注了智能船舶的發展趨勢，增加了關于自動化控制系統安全防護的內容，包括但不限于網絡安全措施、數據傳輸加密等建議。同時，也對電力推進系統的特殊考慮進行了補充說明，如針對不同類型的推進器如何進行有效的過載保護和短路保護。
在測試方法上，《GB/T 7357-2025》引入了更多先進的檢測技術和工具，旨在通過更科學的方法來驗證電氣設備及其系統的性能是否符合預期目標。這不僅有助于提升產品質量，也為后續可能出現的問題提供了更好的追蹤依據。
最后，新版標準還加強了與其他相關國際標準的一致性，比如IEC系列標準，使得中國船舶電氣設備的設計與制造更加國際化，便于參與全球市場競爭。
