The mobile distributed grounding system plays an irreplaceable role in discharging power for intercity trains, including two types of settings (GSs): the working GS provides pathway traction current; protective reference potential vehicle-mounted equipment. As both and GSs share rail as common current-releasing pathway, current released by might return carriage through adjacent GSs, forming train body (TB) which threatens electrical Herein, equivalent circuit is built to analyze TB current....
Abstract When a high‐speed train approaches the insulated phase‐splitting section embedded between neighbouring power supply arms, vacuum circuit breaker (VCB) installed on trains must be disconnected to maintain traction system as no‐load condition for completing phase‐switching action, passes through depending its inertia. However, when operating VCBs, arc is easily triggered mobile contacts inside, accompanied by an overvoltage impulse. Herein, explore generating mechanism of inrush...
As the unique power-discharging channel for high-speed trains, 'train-rail' mobile coupling grounding system plays a vital role in sending traction power back to terrestrial substations, through electrical contact between rotating wheel and steel rail. The whole is composed of two kinds modes: working charge draining into rail track; protective provides reference potential vehicle-mounted equipment. Different from fixed technique normally implemented system, when relative motion occurs train...
In the present study, variations of precipitated phases, microstructure and mechanical properties different heat treatments were investigated. The main phases Al Si in heat-treated specimens. horizontal microstructures as-deposited below 280°C annealing appeared interwoven structures, vertical fish-scale structures. As temperatures higher than 280°C, structures disappeared because phase coarsen along boundaries. With regard to specimen was by solution + artificial aging (T6), strengths...
Atomic layer deposition (ALD) is an emerging coating technique filled with potential that expected to deposit coatings high laser-induced damage threshold (LIDT). As lasers play important role in space exploration which are gradually moving higher orbits and longer lifetimes, a demand for laser has been raising. At the current state of art, reliability ALD-deposited applications unclear. This work presents investigations on stability three oxide under proton UV radiation at values typical...
As a unique reflux path for trains, the ‘train-rail’ mobile grounding system has double functions – traction power feedback and transmission of train's communication signal. With constant increment operational velocity high-speed railway, coupling relationship existing in becomes complicated, when wheels roll over insulated joint. It may result frequent occurrence rolling arc ablation rail ends joints, which might lead to series connection circuit or even trigger misjudgment control system....
The buildings of the Confucius Institute and Media Art in Mozambique adopt a frame structure. Due to building function architect's personalized modeling requirements, project has large planar opening area span We have completed engineering structural design jump column foundation geological conditions under which self-weight collapsible soil. In addition, we also compared analyzed reinforcement calculation "model column" method modified expansion coefficient method, checked failure strength...
