电磁感应与实际相结合的问题较多,如录音原理、话筒工作原理、继电器控制电路的工作原理、日光灯工作原理等,除此之外这里再介绍几个实际应用,供大家参考。1.漏电保护器例1如图1所示是家庭用的“漏电保护器”的关键部分的原理图,其中P是一个变压器铁芯,入户的两根电线(火线和零线)采用双线绕法,绕在铁芯的一侧作为原线圈,然后再接入户内的用电器。Q是一个脱扣开关的控制部分 Electromagnetic induction and the actual combination of more problems, such as recording principle, the working principle of the microphone, the relay control circuit works, working principle of fluorescent lamps, in addition here to introduce a few practical applications for your reference. 1. Leakage Protector Example 1 As shown in Figure 1 is the home of the “leakage protector,” the key part of the schematic diagram, where P is a transformer core, the two wires into the house (FireWire and zero line) Using double winding method, wound on the side of the core as the original coil, and then access the indoor electrical appliances. Q is a control part of the trip switch
