整流器的作用大盘点
整流器在我们的日常生活中随处可见,但你知道它的作用是什么吗?下面小编就给大家详细介绍一下整流器的作用。
整流器简介
通俗讲,整流器就是将交流(AC)转化为直流(DC)的装置。根据定义就不难发现它的主要作用就是:将交流电(AC)变成直流电(DC),经滤波后供给负载,或者供给逆变器。那么整流器究竟有多重要呢?这样说吧,由于所有的电子设备都需要使用直流,但是,一般的电力公司都使用交流,因此除非使用电池供电,否则所有电子设备的电源供应器内部都少不了整流器。可见,整流器对电子设备来说是必不可少的供电装置。再例如,最常见的汽车整流器,它对汽车也起着至关重要的作用。通过整流原理,不仅可以减轻怠速抖动的现象,提升动力、有效改善爬坡加速无力、搓车、掉档等问题,还可以保护电瓶及汽车电气电路系统,延长其使用寿命。所以说,小小的整流器在我们日常生活中发挥着巨大的作用。
整流器的作用一
整流器还可以给蓄电池提供充电电压。因此,它同时又起到了一个充电器的作用。但特别注意的是,操作上除了为负载供电外,整流器应能在10倍于放电时间的时间之内,将蓄电池的放电功率恢复到95%。当蓄电池再次充电后,整流器应使蓄电池保持在充满电的状态,直到下一次放电。
整流器的作用二
整流器有时候并不一定仅仅是用来产生直流作用的,在很早的时期,在矿石收音机上使用被称为“猫须”的金属细线,压在方铅矿晶体上,就构成了点接触整流器,被称为晶体检波器或矿石检波器。因此整流器有时候也可以经过“加工”而取代检波器,它的一个特别的作用便是用来检波。又例如,在瓦斯气体加热系统中,火焰整流就是检验火焰是否存在的“检测仪”,如果火焰存在,火焰外侧的两个金属电极形成的电流路径中,等离子就会对产生的交流电压起到整流的作用。
看了以上内容,关于整流器的作用你是不是更了解了呢?其实,整流器的作用还远不止这些,相信它一定还有更多特别的作用等待人们去发现发现和利用。
整流器的作用是什么?
整流器(英文:rectifier)是把交流电转换成直流电的装置,可用于供电装置及侦测无线电信号等。整流器可以由真空管,引燃管,固态矽半导体二极管,汞弧等制成。相反,一套把直流电转换成交流电的装置,则称为“逆变器” (inverter)。
在备用UPS中只需要给蓄电池充电,不需要给负载供电,故只有充电机。在双变换UPS中,此装置既为逆变器供电,又给蓄电池充电,故称为整流器/充电机。
整流器是一个整流装置,简单的说就是将交流(AC)转化为直流(DC)的装置。它有两个主要功能:之一,将交流电(AC)变成直流电(DC),经滤波后供给负载,或者供给逆变器;第二,给蓄电池提供充电电压。因此,它同时又起到一个充电器的作用。
整流器有什么作用?
整流器作用是整流器是将方向、大小时时在变的交流电,变为方向不变、大小在变的单向脉动电。再经过滤波电路、稳压电路,将脉动电变为大小不变的直流电。
在引擎室里的蓄电池(铅酸电池)乃是汽车的唯一的电力供应来源,举凡从灯、冷气、音响…到电子点火装置都是由蓄电池提供电力,这些车上所使用的电器是并接在电池的正负极端。
拓展资料
工作原理是以电子点火装置而言,若汽车的引擎转速为3600RPM,换算可得60RPS,也就是说在3600RPM的转速下,电池每秒必须提供30次的的电子点火电流,在四缸引擎中,电池每秒必须提供120次的电子点火电流,在此同时,其它电器如音响也需要电源,就会造成音响的实际电压不稳。
