如果出现这几种状况?说明大功率直流稳压电源电子元器件已经损坏
编辑:扬州凯弘电源科技有限公司   发布时间:2019-05-04

任何东西都有固定的使用期限,大功率直流稳压电源电子元器件也有固定的使用寿命。大功率直流稳压电源电子元器件的寿命除了与它本身的结构、性质有关之外,也和它的使用环境以及在电路中所起作用密切相关。

无论是自然损耗所出现的故障,还是人为损坏所出现的故障,一般可归结为电路接点开路,大功率直流稳压电源电子元器件损坏和软件故障三种故障。接点开路,如果是导线的折断,拨插件的断开,接触不良等,检修起来一般比较容易。而大功率直流稳压电源海陆争霸电子元器件的损坏,(除明显的烧坏,发热外),一般很难凭观察员发现,在许多情况下,必须借助仪器才能检测判断,因此对于技术人员来说,首先必需了解各种器件实效的特点,这对于检修电路故障,提高检修效率是极为重要的。
