在典型使用壽命范圍方面，工業控制機箱的平均壽命通常為 8 - 12 年，電子元件老化、散熱條件是影響其使用壽命的關鍵因素，隨著時間推移，電子元件性能逐漸衰退，而不良的散熱條件會加速元件老化；配電柜系統平均壽命在 10 - 15 年，接觸器壽命和絕緣性能對其使用壽命起著決定性作用，接觸器頻繁動作會導致觸點磨損，絕緣性能下降則可能引發隱患；電機驅動系統平均壽命為 5 - 10 年，軸承磨損、繞組絕緣狀況直接關系到其運行時長，軸承長期運轉產生磨損，繞組絕緣在電、熱、機械應力作用下逐漸劣化；自動化控制單元平均壽命處于 6 - 10 年區間，元器件迭代速度以及軟件兼容性是重要影響因素，隨著技術發展，舊有元器件可能難以滿足新需求，軟件更新也可能導致兼容性問題 。

In terms of typical service life range, the average service life of industrial control chassis is usually 8-12 years. The aging of electronic components and heat dissipation conditions are key factors affecting their service life. Over time, the performance of electronic components gradually deteriorates, and poor heat dissipation conditions will accelerate component aging; The average lifespan of the distribution cabinet system is 10-15 years, and the lifespan and insulation performance of the contactor play a decisive role in its service life. Frequent operation of the contactor can cause contact wear, and a decrease in insulation performance may lead to safety hazards; The average lifespan of the motor drive system is 5-10 years, and bearing wear and winding insulation directly affect its operating time. Long term operation of the bearings results in wear, and winding insulation gradually deteriorates under electrical, thermal, and mechanical stress; The average lifespan of automation control units is in the range of 6-10 years, and the iteration speed of components and software compatibility are important influencing factors. With the development of technology, old components may be difficult to meet new needs, and software updates may also lead to compatibility issues.

影響壽命的關鍵因素及應對措施主要涉及電氣元件老化、機械部件磨損以及環境適應性等方面。電氣元件老化表現為電容鼓包、繼電器觸點氧化等問題，電容鼓包意味著內部電解質可能出現泄漏或氣化，影響電路性能，繼電器觸點氧化會導致接觸電阻增大，降低控制精度。針對這些問題，有效的解決方案是每 2 年進行電容 ESR 檢測，當容值偏差超過 20% 時及時更換電容，使用鍍金觸點繼電器，其壽命可超過 100 萬次，有效減少觸點氧化帶來的故障。

The key factors and countermeasures that affect lifespan mainly involve electrical component aging, mechanical component wear, and environmental adaptability. The aging of electrical components manifests as problems such as capacitor bulging and oxidation of relay contacts. Capacitor bulging means that the internal electrolyte may leak or vaporize, affecting circuit performance. Oxidation of relay contacts can increase contact resistance and reduce control accuracy. An effective solution to these issues is to conduct ESR testing of capacitors every 2 years. When the capacitance deviation exceeds 20%, capacitors should be replaced in a timely manner. Gold plated contact relays can be used, with a lifespan of over 1 million times, effectively reducing faults caused by contact oxidation.

機械部件磨損常以導軌卡滯、軸承異響等典型故障呈現，導軌卡滯會影響設備運動精度和順暢性，軸承異響則預示著軸承可能出現損壞。相應的維護方案需結合設備運行狀況和使用環境，對機械部件進行定期檢查和保養，如對導軌進行潤滑、清理雜質，對軸承進行潤滑脂補充或更換 。環境適應性也是影響設備壽命的關鍵因素，關鍵指標涵蓋溫度、濕度和粉塵防護等級。設備適宜運行溫度通常在 - 20℃~+50℃，超出該范圍則需要配備溫控系統進行調節；適宜濕度范圍為 30%~70% RH，在潮濕環境中需安裝防凝露加熱器，避免設備內部產生冷凝水而損壞元件；粉塵環境下，設備需具備 IP54 以上防護等級，防止粉塵進入設備內部影響正常運行 。

Mechanical component wear often presents typical faults such as rail jamming and bearing abnormal noise. Rail jamming can affect the accuracy and smoothness of equipment movement, while bearing abnormal noise indicates that the bearing may be damaged. The corresponding maintenance plan should be based on the operating conditions and usage environment of the equipment, and regular inspections and maintenance of mechanical components should be carried out, such as lubricating the guide rails, cleaning impurities, and supplementing or replacing lubricating grease for bearings. Environmental adaptability is also a key factor affecting equipment lifespan, with key indicators including temperature, humidity, and dust protection level. The suitable operating temperature for the equipment is usually between -20 ℃ and+50 ℃. If it exceeds this range, a temperature control system needs to be equipped for adjustment; The suitable humidity range is 30%~70% RH, and anti condensation heaters should be installed in humid environments to avoid condensation water inside the equipment and damage to components; In dusty environments, equipment must have a protection level of IP54 or above to prevent dust from entering the interior and affecting normal operation.

為延長設備壽命，還需制定科學合理的維護策略。預防性維護計劃尤為重要，每日需進行異常噪音和溫升檢查，及時發現設備運行初期的異常狀況；每月進行緊固件扭矩校驗，嚴格按照標準扭矩表操作，防止因緊固件松動引發設備故障，同時對散熱風扇進行除塵處理，采用壓縮空氣吹掃的方式風扇表面和內部的灰塵，保障散熱效果；每年開展絕緣電阻測試，要求絕緣電阻大于 1MΩ，進行接地電阻檢測，確保接地電阻小于 4Ω，保障設備電氣。

To extend the lifespan of the equipment, it is necessary to develop a scientifically reasonable maintenance strategy. The preventive maintenance plan is particularly important, and daily checks for abnormal noise and temperature rise are required to promptly detect any abnormal conditions during the initial operation of the equipment; Perform monthly torque verification of fasteners and strictly follow the standard torque table to prevent equipment failure caused by loose fasteners. At the same time, dust removal treatment is carried out on the cooling fan, using compressed air blowing to remove dust on the surface and inside of the fan to ensure heat dissipation effect; Carry out insulation resistance testing every year, requiring insulation resistance greater than 1M Ω, and conduct grounding resistance testing to ensure that the grounding resistance is less than 4 Ω, ensuring the electrical safety of the equipment.

此外，關鍵部件更換周期表為設備維護提供了明確指引，冷卻風扇在使用 3 年且轉速下降超過 15% 時需進行更換；電源模塊使用 5 年，若輸出電壓波動超過 5% 則應更換；通信線纜使用 8 年后，通過阻抗測試判斷是否需要更換；機械傳動部件在使用 5 - 7 年時，依據振動分析（參照 ISO 標準）結果決定是否更換，從而保障設備始終處于良好運行狀態 。

In addition, the replacement cycle table for key components provides clear guidance for equipment maintenance, and the cooling fan needs to be replaced after 3 years of use and when the speed drops by more than 15%; The power module should be replaced if the output voltage fluctuates by more than 5% after 5 years of use; After using communication cables for 8 years, determine whether they need to be replaced through impedance testing; Mechanical transmission components should be replaced based on vibration analysis (referring to ISO standards) results after 5-7 years of use, in order to ensure that the equipment is always in good operating condition.
