　　当数据在高速率传输的情况下，线路就呈现传输线效应，此时负载的特性阻抗必须与输出相匹配，否则，就会导致信号回波反射、系统不能正常工作。即使某些情况下，可以通过在末端并联匹配电阻等方法来实现阻抗匹配，但长远来说，一旦该电阻因某种原因改变而会重新发生故障，再说，此种方法还会带来增大系统功率消耗的弊端。

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.

三相异步电动机的反接制动，控制电路图如下：（，电动机反接制动电路）从上图可看出，其主电路和正反转电路类似。不同的是，由于反接制动时，旋转磁场的相对速度较高，差不多为启动时的两倍，定子电流也很大，在反接制动电路中增加了限流电阻R。速度继电器的触头ks串接在控制电路中。电机反接制动过程分析：当电动机转速升高后，速度继电器的动合触点KS闭合，为反接制动接触器KM2接通做准备。停车时，按下复合按钮SB1（其动断触点断开，动合触点闭合），接触器KM1断电释放，动断辅助触点KM1闭合，接触器KM2线圈得电，KM2主触点闭合（同时KM2自锁触点闭合自锁，动断触点KM2断开，对KM1联锁），电动机反接制动。
