电磁继电器在中考的考查中,以“分析自动控制的过程”“根据要求连接电路”及“电路的综合计算”为主,下面结合中考的实例,谈谈如何解答有关电磁继电器的试题.一、根据电磁继电器的电路,分析自动控制的过程解题指导:在分析电磁继电器的自动控制时,可以先分析控制电路.如果是通过通断电路来控制电磁铁的磁性的,那么就要分析什么情况下控制电
Electromagnetic relay test in the examination in order to “analysis of the process of automatic control ” “according to the requirements of the circuit ” and “integrated circuit ” based, with the following examples of the exam, talk about how to answer questions about electromagnetic Relay test questions. A, according to the electromagnetic relay circuit, automatic control of the process of solving problems Guidance: When analyzing the automatic control of electromagnetic relays, you can first analyze the control circuit .If it is through the on-off circuit to control the magnetic magnet , Then analyze the situation under what control of electricity
