Abstract.
Years of operation condition shows that the power source of FTU is the most faulty component as well as the key factor to affect its stability and reliability.Therefore, the reliability of the power supply of FTU is a difficult point of distribution network automation system.
Super capacitor capacitance is proportional to the surface area and is inversely proportional to the plate spacing.Super capacitor electrode is widely used ,and its carbon electrode is composed of the porous carbon material.The porous structure of the material make the surface area of the positive and negative plates reach more than 2000m2/g.Additionally, the interval between the electric double layer is very short, which(<10-10m) is shorter than a conventional capacitor of the film material can achieve.
(5)Environment friendly.Materials used in super capacitor is environment friendly and also won't produce toxic or harmful substances in the process of work

Introduction Atomic hydrogen can be found in many materials and components, often introduced by manufacturing operations as well as due to environmental exposure.
An established method to investigate the contribution of specific microstructural constituents to the HACC susceptibility of the bulk material is to characterise their micro-fractographic behaviour [8].
It is in general found that the HACC susceptibility of a bulk material tends to increase with the increase of its strength (or hardness) and the decrease of its toughness [3].

The yield strength of the aged alloy is mainly influenced by the precipitation hardening, solution strengthening and the inherent strength of the material, it can be usually expressed by the following expression [14]:
(1)
Where , , are the contributions of precipitation hardening, solution strengthening and pure matrix to the yield strength respectively.
Besides, the occurrence of many large carbides at the grain boundaries after long time service also plays a key role in the tensile strength.

In order to find out the influence of SP on early age shrinkage and the shrinkage-reducing effect of
SRA, an aliphatic SP, widely used in present engineering, and a newly developed SRA named
ZDD-A, which is a compound of methyl ether group polymer and ethylene glycol group polymer and
developed by Building Materials Institute of Zhejiang University [11], were selected for research on
the early age shrinkage of concrete.
Experiment Materials and mix proportions.
In engineering, SP is usually used for decreasing w/c while keeping the same slump.
Acknowledgement The authors express their sincere gratitude to graduates and students of Building Materials Laboratory of Zhejiang University who accomplished numerous experiments.
