Precautions for installation of power cables: keep 2m distance when the cable is installed in parallel with the thermal pipe, and 0.5m should be maintained when crossing. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the direct buried depth of 1-35kv cable is less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter. ? 6KV and above cable connector:? When installing the terminal head of the cable, the semiconductor electrical shielding layer must be stripped off. During operation, the insulation shall not be damaged. The shield end should be flat and the graphite layer (carbon particles) should be clean. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and sheath and other accidents. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. ? The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible. Basic re for cable terminals and intermediate joints: a. good conductor connection; B. The insulation is reliable, and it is recommended to use irradiated cross-linked heat-shrinkable silicone rubber insulation materials; C. good sealing; D. sufficient mechanical strength to meet various operating conditions. The end of the cable must be used to prevent water and other corrosive materials from corroding, in order to prevent the water tree caused by the aging of the insulation layer and breakdown. Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. ? Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.

，用户给定的最高工作频率fmax＝120Hz，频率精度为0.01%，则最大误差为：Δfmax＝0.0001×120Hz＝0.012Hz通常，由数字量给定时的频率精度约比模拟量给定时的频率精度高一个数量级，前者通常能达到±0.01%（-10～＋50℃），后者通常能达到±0.5%［（25±10）℃］。频率分辨率指输出频率的最小改变量，即每相邻两挡频率之间的最小差值。，当工作频率fx＝25Hz时，如果变频器的频率分辨率为0.01Hz，则上一挡的最小频率为：fn′＝（25＋0.01）Hz＝25.01Hz下一挡的最大频率为：fx″＝（25－0.01）Hz＝24.99Hz对于数字设定式的变频器，频率分辨率取决于微机系统的性能，在整个调频范围（如0.5～400Hz）内是一个常数（±0.01Hz）。

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。
