Journal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.ABSTRACT Regulated asset base (RAB) and results‐based financing (RBF) are key emerging infrastructure finance models, offering stable returns (RAB) and outcome‐based incentives (RBF). This perspective proposes a hybrid RAB‐RBF model to bridge the “viability gap” in developing regions and catalyze low‐carbon energy infrastructure access where cost ...

Gaoya dianqi, 2019 为了环保,同时解决SF6高压电器设备在低温下可靠运行的问题,研制和应用SF6/N2混合气体的电器设备是非常必要的。而同样压力下的SF6所占比例越高,其密度越大,绝缘能力越强,但节能减排的意义就越小,因此需要研制SF6/N2混合气体密度继电器,用于监测其气体密度,从而既确保高压电器设备安全运行,又能达到较好的节能减排效果。文中提出研制高性能的SF6/N2混合气体密度继电器,并阐述了高性能的SF6/N2混合气体密度继电器的实现方法,以及通过性能测试,证实该SF6/N2混合气体密度继电器具有较好的性能。

Dianci bileiqi, 2015 通过分析测试国内外氧化锌电阻片的电气性能结果及化学成分,发现电气性能优异的原因是在配方中未添加Cr2O3和SiO2成分,而添加了其他微量元素,从而改变了烧成后电阻片的微观结构。通过参考引证有关研究文献和专利,研发出的新型氧化锌电阻片配方的电气性能效果较好。
