Description
技术领域 technical field
本实用新型涉及一种电力线缆，更具体地涉及一种非常规安全多芯电力线缆。The utility model relates to a power cable, in particular to an unconventional safe multi-core power cable.
背景技术 Background technique
目前电线电缆已广泛应用于工业生产、交通运输、建筑工程和设施、现代农业和科研、军工装备或军事设施、太空、海洋的探测中，并已达到了无处不在的状态。随着社会经济的活动内容从深度到广度进行台阶式跳跃式的发展，电线电缆品种不断更新和完善，生产量持续增加。例如，建造高智能化大楼需要有供数百、上千台电子计算机分级联网用的计算机网络电缆；搭建城市公共有线电视网、全市乃至全国所有银行的通存通兑、开展网上经济往来和信息交流等必须装设高可靠性传输用的宽频带电缆网；实现军事上的大炮或高炮群遥控程序发射需要设计出适合野外恶劣环境的控制电缆。At present, wires and cables have been widely used in industrial production, transportation, construction engineering and facilities, modern agriculture and scientific research, military equipment or military facilities, space, ocean detection, and have reached a ubiquitous state. With the step-by-step development of social and economic activities from depth to breadth, the varieties of wire and cable are constantly updated and improved, and the production volume continues to increase. For example, the construction of high-intelligence buildings requires computer network cables for hierarchical networking of hundreds or thousands of electronic computers; the establishment of urban public cable TV networks, the universal deposit and withdrawal of all banks in the city and even the country, and the development of online economic exchanges and information exchanges It is necessary to install a broadband cable network for high-reliability transmission; to realize the remote control program launch of military cannons or antiaircraft artillery groups, it is necessary to design control cables suitable for harsh environments in the field.
电线电缆的应用主要分为三大类：电力系统、信息传输系统和机械设备以及仪器仪表系统。电力系统采用的电线电缆产品主要有架空裸电线、汇流排(母线)、电力电缆、橡套线缆、架空绝缘电缆)、分支电缆(取代部分母线)、电磁线以及电力设备用电气装备电线电缆等。用于信息传输系统的电线电缆主要有市话电缆、电视电缆、电子线缆、射频电缆、光纤缆、数据电缆、电磁线、电力通讯或其他复合电缆等。机械设备、仪器仪表系统中除架空裸电线外几乎其他所有产品均有应用，但主要是电力电缆、电磁线、数据电缆、仪器仪表线缆等。The application of wire and cable is mainly divided into three categories: power system, information transmission system and mechanical equipment, and instrumentation system. The wire and cable products used in the power system mainly include overhead bare wires, bus bars (bus bars), power cables, rubber sheathed cables, overhead insulated cables), branch cables (replacing part of the bus bars), electromagnetic wires, and electrical equipment wires and cables for power equipment wait. The wires and cables used in the information transmission system mainly include local telephone cables, TV cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communication or other composite cables, etc. Except for overhead bare wires, almost all other products in mechanical equipment and instrumentation systems are used, but mainly power cables, electromagnetic wires, data cables, instrumentation cables, etc.
电线电缆产品主要分为五大类：裸电线及裸导体制品、电力电缆、电气装备用电线电缆、通讯电缆及光纤和电磁线。其中电力电缆的主要特征在导体外挤(绕)包绝缘层，如架空绝缘电缆，或几芯绞合(对应电力系统的相线、零线和地线)，如二芯以上架空绝缘电缆，或再增加护套层，如塑料/橡套电线电缆。主要的工艺技术有拉制、绞合、绝缘挤出(绕包)、成缆、铠装、护层挤出等。Wire and cable products are mainly divided into five categories: bare wires and bare conductor products, power cables, wires and cables for electrical equipment, communication cables, optical fibers and electromagnetic wires. Among them, the main feature of the power cable is that the insulation layer is extruded (wound) outside the conductor, such as an overhead insulated cable, or several cores are twisted (corresponding to the phase wire, neutral wire and ground wire of the power system), such as an overhead insulated cable with more than two cores, Or add a sheath layer, such as plastic/rubber sheathed wire and cable. The main process technologies are drawing, stranding, insulation extrusion (wrapping), cabling, armoring, and sheath extrusion.
电力电缆的选择应遵照以下原则：电缆的额定电压要大于或等于安装点供电系统的额定电压；电缆持续容许电流应等于或大于供电负载的最大持续电流；线芯截面要满足供电系统短路时的稳定性的要求；电压降符合电缆长度的要求；线路末端的最小短路电流应能使保护装置可靠的动作。The selection of power cables should follow the following principles: the rated voltage of the cable should be greater than or equal to the rated voltage of the power supply system at the installation point; the continuous allowable current of the cable should be equal to or greater than the maximum continuous current of the power supply load; Stability requirements; the voltage drop meets the cable length requirements; the minimum short-circuit current at the end of the line should enable the protective device to operate reliably.
然而，目前通用的线缆存在着一定的缺陷。例如，随着经济社会生活的不断提高，用电量也随之大幅度增加，这样输入到线缆的输入电压也逐级提高，因此，线缆升温迅速，导致线缆不能经受高温并不断发热烧毁，从而大大影响整个线缆电路的实现。另外，当线缆接入到其他线路时，线缆接入端需要进行脱皮处理，而现有的线缆中包裹导体外层的材料脱皮异常困难。此外，导体一般为圆形，多芯线缆的若干导体之间难免有空隙，当在这些导体外挤(绕)包绝缘层、护层后，导体被挤压而形成了波浪型的外观，大大影响了线缆的手感和美感。However, the current general-purpose cables have certain defects. For example, with the continuous improvement of economic and social life, the power consumption has also increased significantly, so the input voltage to the cable has also increased step by step. Therefore, the temperature of the cable rises rapidly, causing the cable to be unable to withstand high temperatures and continue to heat up. Burned, which greatly affects the realization of the entire cable circuit. In addition, when the cable is connected to other lines, the cable access end needs to be peeled off, and it is extremely difficult to peel off the material covering the outer layer of the conductor in the existing cable. In addition, the conductors are generally circular, and there are inevitably gaps between the conductors of the multi-core cable. When these conductors are extruded (wrapped) with insulating layers and sheaths, the conductors are extruded to form a wavy appearance. Greatly affects the feel and aesthetics of the cable.
因此，有必要提供一种改进的电力线缆来克服上述缺陷。Therefore, it is necessary to provide an improved power cable to overcome the above defects.
