Electromagnetic field simulation of vacuum circuit breaker

A typical unipolar longitudinal magnetic field contact structure - Cup longitudinal magnetic contact structure is analyzed. The structure of cup-shaped longitudinal magnetic contact is shown in Fig. 1 (a). Contacts have six cup fingers, and the angle between the cup finger and the horizontal plane is 27 degrees. Each cup finger rotates 90 degrees. There are six radial straight grooves on the contact sheet. The contact material is CuCr50. ##### 微型发电机电磁场仿真

Electromagnetic field simulation of micro-generator

An example is given to describe the electromagnetic field problem of the simulated micro-generator. Requirements: (1) When 10000rpm, 40V RMS of AC voltage and 150mA of load current, the optimum number of turns and wire diameter are obtained. (2) When the voltage is 50 000 rpm, the maximum voltage is obtained. (3) The model is built in MagNet software to build a 3D model, part of which is modeled around the vertical direction. ##### 三相箱盖和升高座磁场温度场仿真
