To meet the force characteristics test for electromagnetic actuator under high temperature, a force characteristics test system for high temperature electromagnetic actuators is presented. In this paper, the structure of the system are introduced and the thermal finite element model of the system are established. The influences of the screw joint and the structure parameters of heat insulation component...
We investigated the influence of thermal deformation on the magnetic properties of flexible FeGa/IrMn exchange-biased (EB) bilayers grown on polyvinylidene fluoride (PVDF) membranes with the pinning direction parallel to the thermal deformation directions $\alpha _{31}$ and $\alpha _{32}$ of PVDF. Because with increasing temperature, the uniaxial anisotropy is reoriented from the $\alpha _{32}$ ...
Field signature method (FSM) is used today by many of the world's major oil companies in a wide range of monitoring applications, with advantages of high degree of reliability and accuracy, non-intrusive, reflecting wall thickness visually. In this paper, the theory of FSM used in inner corrosion monitoring was analyzed and the expression of defects evaluation parameter (Fc) was deduced based on the...
In the practice process of high temperature float glass online measurement, the thickness of the glass, which is the target being measured by system, is changing with the time and space. The input and the experimental result are changing with time. The data input by instrument has not only the data of certain thickness of glass, but also many uncertain data which cannot be express by clear and definite...
Electrical cables are widely used in urban electrical transmission. It is necessary to monitor whether it operate normally or not. The conductor temperature is a key parameter should be monitored. However the conductor temperature of underground cables is very hard to measure for technical difficulties, the other option is calculation. The conductor temperature is associated with the temperature and...
Cable ampacity is always concerned by the electric power operating and scheduling engineerer. Calculation of cable ampacity is quite complex and calculation error is hard to evaluate because there are many influencing factors and some factors is changeable. Furthermore, on account of current power cable's manufacture, laying and operation circumstances are much different from before which also will...
