【摘要】：隨著人們對(duì)電能需求的增大,大城市用電量增加,負(fù)荷密度增大,需要采用更高輸送能力的輸電方式,500kV電纜輸電系統(tǒng)作為目前國(guó)際上投入商業(yè)化運(yùn)行的電壓等級(jí)最高的電纜輸電方式,是未來特大型城市電能輸送的主要形式,同時(shí)也是目前水電站電能送出的一種主要方式。 本文分析了500kV電纜的電場(chǎng)分布情況,選擇了用于電應(yīng)力控制的方法,選擇了應(yīng)力錐的制作材料,并對(duì)應(yīng)力錐尺寸制作的研究方法進(jìn)行了分析,確定了電纜附件的結(jié)構(gòu)形式。 本文根據(jù)電纜附件的尺寸及安裝要求,制定了三種電纜附件的安裝工藝和兩種專用工藝,并對(duì)電纜附件的安裝環(huán)境提出了要求。 本文根據(jù)海淀500kV電纜系統(tǒng)短路電流的水平和接地系統(tǒng)的方式,經(jīng)過計(jì)算確定了接地電纜和同軸電纜的截面、中間接頭交叉互聯(lián)箱內(nèi)的護(hù)層保護(hù)器性能要求。 本文進(jìn)行了電纜及隧道運(yùn)行監(jiān)測(cè)系統(tǒng),確定了主要監(jiān)測(cè)因素,并制定了相應(yīng)的實(shí)施措施,為海淀500kV電纜線路的運(yùn)行安全提供了保證。
[Abstract]:With the increase of people's demand for electricity, the power consumption in big cities increases, and the load density increases. As the highest voltage transmission mode in commercial operation in the world, the 500kV cable transmission system, which needs a higher transmission capacity, is the main form of electric power transmission in large cities in the future. At the same time, it is also a main way to send out the electric energy of hydropower station at present. In this paper, the electric field distribution of 500kV cable is analyzed, the method of electric stress control is selected, the material of stress cone is selected, the research method of the size of stress cone is analyzed, and the structural form of cable accessory is determined. According to the size and installation requirements of cable accessories, the installation technology and two special processes of three kinds of cable accessories are formulated in this paper, and the requirements for installation environment of cable accessories are put forward. According to the level of short-circuit current in Haidian 500kV cable system and the mode of grounding system, the performance requirements of protective protector in the interconnecting box of interconnecting intermediate joint and earthing cable are determined by calculating the cross-section of grounding cable and coaxial cable. In this paper, the cable and tunnel operation monitoring system has been carried out, the main monitoring factors have been determined, and the corresponding implementation measures have been drawn up, which provide a guarantee for the operation safety of Haidian 500kV cable line.
