匯流排作為電力傳輸的核心載體，其安全穩定運行直接影響整個電力系統的可靠性。規範的維護與檢查，是預防故障、延長使用壽命的關鍵手段。Busway, as the core carrier of power transmission, its safe and stable operation directly affects the reliability of the entire power system. Standardized maintenance and inspection are key measures to prevent failures and extend the service life.
日常巡檢是匯流排維護的基礎。巡檢時，需重點關注匯流排表面是否存在損傷、變形，外殼是否完整，防護等級是否符合環境要求。對於連接部位，要檢查螺栓是否鬆動、觸頭是否氧化，一旦發現連接部位發熱、變色，可能預示著接觸不良，需立即處理。同時，通過紅外熱成像儀檢測匯流排的溫度分佈，若局部溫度異常升高（如超過正常運行溫度 20℃以上），需及時排查原因，防止因過熱引發火災等嚴重事故。Daily inspections are the foundation of busway maintenance. During inspections, special attention should be paid to whether there is any damage or deformation on the surface of the busway, whether the casing is intact, and whether the protection level meets the environmental requirements. For the connection parts, check whether the bolts are loose and whether the contacts are oxidized. Once the connection parts are found to be heated or discolored, it may indicate poor contact and immediate action is required. At the same time, use an infrared thermal imager to detect the temperature distribution of the busway. If the local temperature rises abnormally (such as more than 20°C above the normal operating temperature), the cause should be investigated in a timely manner to prevent serious accidents such as fires caused by overheating.
定期的深度維護不可或缺。每半年至一年，應全面清理匯流排內部灰塵、雜物，避免因積塵導致絕緣性能下降。對於裝甲型匯流排，需檢查絕緣材料是否老化、開裂，尤其在高溫、潮濕環境下，絕緣層的老化速度更快，需重點監測。此外，對匯流排的支撐和固定裝置進行檢查，確保其牢固性，防止因振動、位移導致匯流排損壞。Regular in - depth maintenance is indispensable. Every six months to a year, the interior of the busway should be thoroughly cleaned of dust and debris to avoid a decrease in insulation performance due to dust accumulation. For compact busways, check whether the insulation materials are aging or cracked, especially in high - temperature and humid environments where the aging rate of the insulation layer is faster and requires key monitoring. In addition, inspect the supporting and fixing devices of the busway to ensure their firmness and prevent damage to the busway caused by vibration or displacement.
故障排查與修復是維護工作的重要環節。當匯流排出現短路、漏電等故障時，需迅速定位故障點。通過檢測絕緣電阻、檢查熔斷器狀態，結合故障現象分析原因。若確定為局部絕緣損壞，需及時更換受損部件；若因超載導致匯流排變形，則需調整負載分配，必要時更換更大規格的匯流排。Fault diagnosis and repair are important aspects of maintenance work. When faults such as short circuits or electric leakage occur in the busway, the fault location needs to be quickly identified. Analyze the causes by testing the insulation resistance, checking the fuse status, and combining with the fault phenomena. If local insulation damage is determined, the damaged components should be replaced in a timely manner. If the busway is deformed due to overloading, the load distribution needs to be adjusted, and if necessary, a busway of a larger specification should be replaced.
匯流排的維護與檢查需嚴格遵循規範流程，從日常巡檢到深度維護，每個環節都不容忽視。只有建立科學的維護體系，才能確保匯流排持續、穩定地為電力系統保駕護航。The maintenance and inspection of busways must strictly follow the standardized procedures. Every link, from daily inspections to in - depth maintenance, cannot be ignored. Only by establishing a scientific maintenance system can the busway continuously and stably safeguard the power system.
