Transmission integration of power and the gas could be realized If a superconducting DC cable uses liquefied natural gas (liquefaction temperature: 110K) or liquid hydrogen (liquefaction temperature: 27K) as the cooling medium. Therefore, the efficiency and reliability of the liquefied natural gas (LNG) integrated energy transfer system can be improved using superconducting DC energy transfer...
In South Korea, Korea Electrotechnology Research Institute (KERI) has developed 154 kV smart HTS cables since 2017. The smart HTS cable has a fault current limiting function. There are two types under development, resistive and inductive.
When the HTS conducting layer of a resistive smart HTS cable is quenched by a large fault current flowing to the HTS layer, the resistance of the cable...
Compared with traditional open fire heating, induction heating has the advantages of high efficiency, energy saving and environmental protection. There are two basic forms of induction heating: longitudinal flux induction heating (LFIH) and transverse flux induction heating (TFIH). The magnetic induction line produced by TFIH is perpendicular to the heated workpiece, which is suitable for...
Electromagnetic forming is a technology that employed electromagnetic force to accomplish the deformation of the metal with high conductivity. It is reported that the improved formability and reduced spring back are observed during the EMF. Combined other advantages such as good control performance and contact-less, EMF technology draw more attentions as a promising solution for the room...
In aluminium manufacturing plants typical billets having 200 mm diameter and 1000 mm height are pre-heated to a temperature of 723.15–773.15 K in order to soften the metal before it is pressed through the extruder. Due to the similar physical properties of aluminium and copper the efficiency of these heaters is in the order of 50%. In order to improve the efficiency superconducting DC...
In the project construction and daily maintenance of overhead power distribution lines, it is necessary to know the actual situation of the auxiliary parts for power polses, such as chassis, chuck and puller, to prevent the poles from pulling up, sinking and lodging. But due to the inconvenient excavation of power poles or the large amount of excavation work, trenchless detection technology...
Due to low acoustic noise, low vibrations, reduced maintenance and inherent overload protection, magnetic gear (MG) has been extensively used in many industrial applications for transmitting torques and adjusting speeds. However, the biggest shortcoming of MGs is their poor torque densities. Although several attempts have been conducted for improving their torque density, such as optimizing...
Compared with mechanical gear, Magnetic gear has the advantage of low acoustic noise, low vibrations, reduced maintenance and inherent overload protection. Although magnetic gears have many merits, the utilization of PMs and torque density of magnetic gears are extremely low due to the influence of parallel-axis topologies. In recent years, coaxial magnetic gear (CMG) has been put forward, and...
In the construction of distribution transmission network, in order to check whether the poles and towers are built as required, it is necessary to detect the underground tower base which is made up of concrete-filled steel tubular. The transient electromagnetic method can obtain location information of underground metals when they induced secondary induced voltage on receiving coil caused by...
