| 目的 针对不同设计使用年限的导管架平台，通过对比新型阳极和常规阳极用量来评价新型阳极的优势和不足。方法 针对设计寿命15年和30年的导管架平台，计算满足不同阶段保护电流需求的新型阳极和常规阳极的需求量。结果 当导管架平台设计年限较短，比如15年，牺牲阳极用量由初期保护电流需求量决定，新型阳极的使用可以达到节约阳极用量的目的。当设计年限较长，比如30年，牺牲阳极用量则由维持电流需求量决定，采用新型阳极并不能节约阳极用量。结论 并非所有设计年限的导管架平台使用新型阳极都能达到节约用量的目的，具体要根据实际计算结果而定。 |

| Objective To evaluate advantages and disadvantages of the new type anode by comparing with the conventional anode according to the jacket platform with different design service life. Methods For the 15 years and 30 years designed jacket platform, the demand for new type and conventional anodes that meet the needs of different stages of protection current were calculated. Results When the design life of the jacket platform was relatively short, such as 15 years, the amount of sacrificial anode was determined by the initial protection current demand. The use of new type anode can achieve the purpose of saving anode usage. When the design life of the jacket platform was relatively long, such as 30 years, the amount of sacrificial anode was determined by the holding current. The use of the new type anode cannot save anode usage. Conclusion Not all design life of the jacket platform using the new type anode can achieve the purpose of saving the amount. It depends on the actual calculation results. |
