三，LED灯具本身质量不过关，常见问题基板漏电等。解决方案：这个没什么好说的，只能换灯，买质量过关有保障的灯具。四，零线带电，家庭线路零线带电的情况不多。如果是三相电分出来的单相电，偶尔有零线带电的情况，比如三相电压不平衡，线路过长，电流过大等等，都会引起零线带电。解决方案：加装LED防微光保护器，即使有以上各类原因，都可以解决关电后微亮的现象。五，不要使用电子开关，电子开关内部有指示灯，开和关的时候都有指示灯，所以关灯以后开关里还是有微弱电流，也会引起LED灯微亮。

　　现代工业中，各类变频设备的节能效果十分明显，在大功率电机中采用变频调速电机，整个发电机组可节电30％。并且使用变频调速后，实现了电机的软启动，使电机工作平稳，电机轴承磨损减小，延长了电机使用寿命和维护周期。

In flame retardant series products, has been successfully used in the oxygen isolation technology, not only 0.6/1 kv polyvinyl chloride insulated and crosslinked polyethylene insulation flame retardant power cable can achieve GB/T12666.5 "into A bunch of power cable test" in class A, and rated voltage up to and including 6/10 kv 6/10 kv crosslinked poly (flame retardant power cable can reach A high class A demand and A large margin. On the basis of high flame retardant and high flame retardant cross-linked insulation, a low-smoke halogen-free high-flame retardant oxygen insulation layer power cable was added, and its low-smoke halogen-free performance was in line with GB/T17651.1.2 and GB/ t1765650.1.2. In this way, the overall level of the company's cross-linked power cable is lower than the domestic status.



　　矿用阻燃通信电缆于2002年10月31日获煤矿产品安全标志证书，年多次扩大了安标产品的认证范围，MHYAV、MHYA32、MHYV、MHY32、MHYVP、MKVV、MKVV22、MKVV32等多种型号的产品均获得了安标证书。

从这层电磁转换的过程而言，可以让“电磁”效应替代人做大电流通断这个“体力活”，只要一个小指头按一下一个小按钮就可以满足要求了，可以设想一下，你去直接打一个很大电流的空气开关，可是相当费劲的事情，有了接触器这些就让人轻松很多。实际上，让人干活轻松点只是继电器和接触器作用的一小方面，关键操作起来安全了，让人离大电流和高电压远一点。同时接触器和继电器可以带很多辅助触头或者中间触点，这些触点能用来组合可以实现各种复杂的控制逻辑，满足工业上复杂的控制要求，让设备更加智能点。

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 buried depth of 1-35kv cable is not 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 is not 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. 6 kv and above cable joint: (1) installing a cable terminal head, must be stripped semiconductor electric shielding layer, operation shall not damage the insulation, should avoid mark uneven situation, when necessary use sand paper to grind; The shield end should be flat and the graphite layer (carbon particles) should be cleaned. (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 accidents such as burning sheath. 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 erosion of water and other corrosive materials, so as to prevent breakdown due to the aging of the insulation layer caused by water trees. 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 done by the installation personnel or full-time technical personnel familiar with the performance of wire and cable. If there are still unclear matters, please consult the relevant technical department or the technical department of our factory.
