【摘要】:目前,超高壓交流輸電線路使用較多的是酒杯型塔,運(yùn)行線路空間磁場強(qiáng)度沿酒杯型塔不同位置分布水平不同。隨著超高壓線路帶電作業(yè)的開展,對(duì)登塔帶電作業(yè)人員的安全防護(hù)提出了較高要求。由于鐵磁性材料對(duì)磁場分布具有一定的畸變作用,為了明確鐵塔內(nèi)磁場分布水平,確認(rèn)工作人員在塔窗內(nèi)工作時(shí)受磁場強(qiáng)度影響情況,測量了500 kV交流線路酒杯型塔典型位置點(diǎn)的磁場強(qiáng)度,并仿真計(jì)算了測量點(diǎn)處沿鐵塔表面的磁場分布水平,測量與計(jì)算結(jié)果具有較好的一致性。計(jì)算與實(shí)測結(jié)果表明:酒杯型塔塔窗內(nèi)磁場分布水平遠(yuǎn)小于國際非電離輻射防護(hù)委員會(huì)推薦的工頻磁場職業(yè)暴露值,不會(huì)對(duì)帶電作業(yè)人員健康產(chǎn)生影響,帶電作業(yè)人員在進(jìn)行500 kV交流線路帶電作業(yè)時(shí)無需對(duì)磁場采取防護(hù)措施。
[Abstract]:At present, the UHV AC transmission lines mostly use the wine cup tower, and the distribution level of the space magnetic field intensity along the wine cup tower is different. With the development of live operation of EHV line, the safety protection of the operators of the tower live line is put forward. Because ferromagnetic material has some distortion effect on magnetic field distribution, in order to determine the level of magnetic field distribution in the tower, it is confirmed that the workers are affected by the magnetic field intensity while working in the tower window. The magnetic field intensity of the typical position of the wine cup tower of 500 kV AC transmission line is measured and the magnetic field distribution level along the surface of the tower is simulated and calculated. The results are in good agreement with the calculated results. The calculated and measured results show that the level of magnetic field distribution in the glass tower window is much lower than the occupational exposure value of the industrial frequency magnetic field recommended by the International Commission on Non-ionizing radiation Protection, and it will not affect the health of the workers working in charge. Live-line operators do not need to take protective measures against magnetic field in 500 kV AC line.
