在电路分析时,经常会遇到保护电路的问题,虽然只增添了几个元器件,却能使电路安全稳定地工作.谁在为电路保驾护航?一个完整的电路保护要考虑过流、过压、过热三个方面,由于初中学生所学知识的限制,本文仅从过流方面进行探讨,以期培养学生保护电路的意识.过流保护电路是电路中不可缺少的重要组成部分,根据其保护方式的不同可分为断开方式和限流方式.1断开式断开式是采用在电路中加入熔断器、漏电保
In the circuit analysis, often encounter the problem of the protection circuit, although only added a few components, but can make the circuit safe and stable work. Who is escorting the circuit? A complete circuit protection to consider over-current, over Pressure, overheating three aspects, due to the knowledge of junior high school students to limit, this article only from the over-flow aspects, in order to cultivate students awareness of the protection circuit.Over-current protection circuit is an indispensable part of the circuit, according to its protection Different ways can be divided into ways to open and limit the way .1 disconnect disconnect type is used in the circuit by adding fuses, leakage protection
