Static Characteristic Analysis of Electromagnetic Release of Photovoltaic Low Voltage DC Circuit Breaker
Low voltage DC circuit breaker plays an important role in the protection of the photovoltaic power generation system.The static characteristic of electromagnetic release of photovoltaic low voltage DC circuit breaker is analysed,and the three-di-mensional model of electromagnetic release is established in the finite element analysis software ANSYS,then the two-dimension-al static characteristic curve of the electromagnetic suction on the moving core under different circuit current and different air gap is obtained after loading and solving.After the secondary development of the finite element analysis software ANSYS,the change curves of electromagnetic suction on the moving core under different structural parameters are obtained,and the corresponding ex-planations are given.At the same time,according to the influence of the structural parameters on the electromagnetic suction at the initial position,the corresponding tolerance suggestions for each parameter are put forward.
