Fire - resistant cable refers to the cable which can keep safe operation for a certain period of time under the condition of flame burning. China's national standard GB12666.6 IEC331 (e) will fire test points A, B two levels, A grade flame temperature of 950 ~ 1000 ℃, the duration for fire, 90 min, class B flame temperature of 750 ~ 800 ℃, for fire duration 90 min, during the whole test, the sample should be under the rated voltage value of the product. Fire-resistant cable is widely used in high-rise buildings, subway, underground street, large power stations and the important industrial and mining enterprises and other related to fire security and its lifesaving, for example, fire fighting e and emergency light guide emergency facilities such as power supply circuit and control circuit.

对于风机类负载,应观察停机后风叶是否因自然风而反转,若有反转现象,应设置启动前的直流制动功能。停车试验停车试验内容主要有:将变频器的工作频率调到高频率,然后按下停机键,观察系统是否出现过电流或过电压而跳闸现象,若有此现象出现,应延长减速时间。b.当频率降到OHz时,观察电动机是否出现“爬行”现象(电动机停不住),若有此现出现,应考虑设置直流制动。带载能力试验带载能力试验内容主要有:a.在负载要求的低转速时,给电动机带额定负载长时间运行,观察电动机发热情况,若发热严重,应对电动机进行散热。

为便于安装、运行和维护,在二次回路中所有设备间的连线都要进行编号,称为二次回路标号。标号一般采用数字或数字和文字的组合,它表明了回路的性质和用途。二次回路标号的基本原则:凡是各设备间要用控制电缆经端子排进行连接的连接导线,都要按回路编号原则进行编号。某些装在屏顶上的设备与屏内设备的连接也需经过端子排,此时屏顶设备就可看作是屏外设备,而在其连接线上同样要按回路编号原则给予相应的编号。为明确起见,对直流回路和交流回路采用不同的标号方法,而在交、直流回路中,对各种不同的回路又赋予不同的数字符号。
