Icing risk assessment and reinforcement measures of 500 kV transmission tower

电力工程技术, 2023
The existing of transmission line icing may lead to the collapse of the transmission tower and disconnection of the transmission line, which seriously threatens the safe and stable operation of power grid. In this paper, aiming at the typical icing lines

Dynamic response analysis of transmission tower line system under random fluctuating wind field

电力工程技术
The transmission tower and tower line coupling system is an important carrier of the power system transmission process. Strong winds in coastal areas have a significant impact on the transmission tower and tower line system. To study the dynamic response

Analysis on Galloping of iced conductor of Transmission Tower-line System [PDF]

Advances in Engineering Research, 2015
Nonlinear finite element model of a transmission tower-line system was set up and galloping of iced bundle conductors in the system was numerically simulated by means of ANSYS software.The galloping trajectories,vibration frequency, galloping order, conductor tension and unbalanced tension characteristics of iced conductors were obtained.

Design and Test of a Forward Neutron Calorimeter for the ZEUS Experiment [PDF]

, 1997
A lead scintillator sandwich sampling calorimeter has been installed in the HERA tunnel 105.6 m from the central ZEUS detector in the proton beam direction. It is designed to measure the energy and scattering angle of neutrons produced in charge exchange

Structure of Magnetic Tower Jets in Stratified Atmospheres [PDF]

, 2006
Based on a new approach on modeling the magnetically dominated outflows from AGNs (Li et al. 2006), we study the propagation of magnetic tower jets in gravitationally stratified atmospheres (such as a galaxy cluster environment) in large scales ($>$ tens

Overcoming the boundary layer turbulence at Dome C: ground-layer adaptive optics versus tower [PDF]

, 2009
The unique atmospheric conditions present at sites such as Dome C on the Antarctic plateau are very favorable for high spatial resolution astronomy. At Dome C, the majority of the optical turbulence is confined to a 30 to 40 m thick stable boundary layer
