  可靠接地时整个485线路的地线必须要有良好的接触,从而保证电压一致,因为在实际施工中,为了接线方便,将线剪成多段再连接,没有将屏蔽线作良好的连接,从而使得其地线分成了多段,电压不能保持一致,导致共模干扰。


  最高传输频率分别为30MHz与100MHz。

蜂鸣器的压降很难获知,有些蜂鸣器的压降可能变动,这样一来基极电阻阻值就很难选择,阻值选择太大就会驱动失败,选择太小,损耗又变大。
d电路也会出现同样的问题,不建议选用图二的这两种电路。
图三这两个电路,电路的驱动信号为3.3VTTL电平,常出现在3.3V的MCU电路设计中,如果不注意就很容易就设计出这两种电路,而这两种电路都是错误的。
先分析e电路,这是典型的“发射极正偏,集电极反偏”的放大电路,或者叫射极输出器。

一般来说,不管我们做什么工作,从事什么行业,保障自身生命安全都是第一位的。
这也就是高压验电器一个比较重要的作用,为了检修工人在检查高压线路和电力设备时,判断这些设备是否带电,以此来判断的工作计划。
可以这样说:高压验电器,是电力检修员工开启生命保障的重要一步。
高压验电器是用来检查高压线路和电力设备是否带电的工具,是变电所常用的最基本的安全用具。
检查线路或者设备是否带电,目的是为了保障人身安全,正确使用高压验电器验电必须做到如下几点:投入使用的高压验电器必须是经电气试验合格的验电器,高压验电器必须定期试验,确保其性能良好。
