Research on automatic rust removing robot for launch site transfer track

Yufei Gu, Shaojiang Chen, Bo Zhang, Penghu Li et autres

In view of the fact that the rusting speed of the transfer track in coastal launch site is fast and the rust-removing efficiency is low, which affects the reliability of the transfer, an automatic rust-removing robot for the transfer track is designed …

Research on characteristic parameters for multi-factor aging of stator bar insulation of pumped storage generator

Xiangdong Liu, Jiaxuan Han, Liangliang Nie, Xingxiao Shao et autres

The real stator bars of an 18kV pumped storage generator were taken as research objects. The multi-factor sequential aging tests of thermal cycling, electrothermal and vibration were carried out. The dielectric loss angle tangent (tanδ), capacitance (C), Δtanδ, ΔC and maximum partial …
