Non-combustible mineral insulated cables may be used in oil tank areas, public buildings with important wooden structures, high temperature places, and other situations where fire resistance requirements are high and installation is acceptable and economic performance is acceptable. When the self-capacity oil filled cable is applied to the public corridor, passenger tunnel, bridge and other situations requiring fire prevention treatment, it can be buried in sand. Close to the cable trench of high voltage current, voltage transformer and other oil-bearing equipment, it is advisable to seal the trench cover plate in this section.
以平端面的四分点作为基准点,先利用基准刀进行断面一刀运行退出和车外圆一刀运行退出,在选用部件加工所用刀具,将其放置在平端面四分点处,如此可以确定起刀点,进行数控机床加工。以平端面四分点处为基准点,精准对刀在每次基准刀退出时记下屏幕显示数据,加工到直接到达对应坐标即可。综合以上内容的分析,可以充分说明数控机床加工中有效运用对刀技巧来进行对刀操作是非常有效的,可以提高对刀操作的准确性,为高质高效的进行数控加工创造条件。

4.485布线可以任意布设成星型接线与树形接线。485布线规范是必须要手牵手的布线,一旦没有借助485集线器和485中继器直接布设成星型连接和树形连接,很容易造成信号反射导致总线不稳定。很多施工方在485布线过程中,使用了星型接线和树形接线,有的时候整个系统非常稳定,但是有的时候则总是出现问题,又很难查找原因,一般都是由于不规范布线所引起的。

ModBus数据通信采用Master/Slave方式(主/从),即Master端发出数据请求消息,Slave端接收到正确消息后就可以发送数据到Master端以响应请求;Master端也可以直接发消息修改Slave端的数据,实现双向读写。在串行通信中,用“波特率”来描述数据的传输速率。国际上规定了一个标准波特率系列:1300、600、1200、1800、2400、4800、9600、14.4Kbps、19.2Kbps、28.8Kbps、33.6Kbps、56Kbps。
