摘要:在21世紀的今天，隨著電力行業(yè)的穩(wěn)步快速發(fā)展，變電站已經(jīng)逐漸成為電力系統(tǒng)中不可或缺的重要組成部分。因此，變電站能否安全可靠運行就顯得尤為重要。在所有影響變電站安全運行的因素中，雷電的破壞性毋庸置疑是非常巨大的，變電站是整個電力系統(tǒng)的心臟和樞紐，一旦變電站遭受雷擊危害，很有可能會引起變壓器等其他重要電氣設備的絕緣損壞，這些損壞不僅僅是修復起來困難程度較大，而且可能同時造成大面積、長時間的停電，這就必然會給國民經(jīng)濟帶來嚴重損失，也會給人們的日常生活造成諸多不便。本設計針對110KV變電站的防雷保護進行了設計，講述了防雷保護的歷史及發(fā)展情況，并且根據(jù)變電站的實際情況做出了具體保護措施。由變電站的建筑情況，選擇避雷針的安裝位置，通過適量的計算保證避雷針的保護范圍無死角，使得變電站整個站區(qū)都在避雷針保護之下。此外，計算變電站的短路電流，由短路電流的計算結果，確定變電站的接地網(wǎng)設計方案，達到保護全站的目的。 關鍵詞 變電站；防雷保護；保護范圍；接地網(wǎng)
Abstract:Today in the 21st century, with the steadily rapid development of power industry, substation has become the indispensable important component. As a result, safe and reliable operation of the substation is very important. Among all the factors affecting the safe operation of the substation, lightning destructive undoubtedly is very huge, Substation is the heart and hub of the electric power system, once the substation is damaged, it is likely to cause the insulation of the transformer and other important electrical equipment damage, the damage is not only difficult to repair, and it may lead to large area and long time power outage at the same time, this will inevitably brings to the national economy serious loss, also it can cause so much inconvenience to people's daily life. This design is for the design of 110kv substation lightning protection, it tells about the history and development of the lightning protection, and it made protection measures according to the actual situation of substation. According to the substation construction situation, i choose the installation location of lightning rod, make sure that there is no dead angle of lightning rod through the moderate calculation, so that the substation lightning protection can cover the station. In addition, calculate the substation of the short circuit current, through the short-circuit current calculation results, make the substation ground network design plan, achieve the purpose of protection of total station.
