Magnetic Circuit Model and the Calculation of Qualified Rate for Magnetic Latching Relay
The magnetic field simulation method for calculation of magnetic latching relay can reach high accuracy.However, it is not fit for the calculation of products qualified rate as its low computation speed.According to the analysis of the advantage and disadvantage of magnetic circuit method, this paper presented a magnetic circuit model considering the leakage flux based on the adjustment coefficient.Then, a computing method for qualified rate of relay virtual sample dynamic and static characteristics was given by stress-strength interference model.The computing example shows that the calculation results using the methods above can meet the engineering requirements, and the calculation efficiency is greatly improved, which lays the foundation for the quality consistency design and control of the electric energy meter.
