摘 要:為了縮短 10 kV 開關(guān)柜接地線裝設(shè)時(shí)間,根據(jù)變電站倒閘操作現(xiàn)場(chǎng)實(shí)際流程,對(duì)現(xiàn)有安全工器具進(jìn)行了改進(jìn)并縮短了操作時(shí)間。使用關(guān)聯(lián)圖對(duì)影響操作時(shí)間的主要問題進(jìn)行分析,并對(duì) 6 條末端因素逐條分析確認(rèn),確定螺旋發(fā)力導(dǎo)致導(dǎo)體端難以固定是主要因素,通過借鑒剝線鉗彈簧結(jié)構(gòu),制作新型結(jié)構(gòu)的開關(guān)柜接地線,大幅縮短固定導(dǎo)體端時(shí)間,從而縮短了 10 kV 開關(guān)柜接地線整體裝設(shè)時(shí)間,并在實(shí)際操作中得到了驗(yàn)證。
關(guān)鍵詞: 開關(guān)柜;接地線;螺旋;彈簧結(jié)構(gòu)

Abstract: This research improved the existing safety tools and reduced the operation time according to the actual process of switching operation in the substation to shorten the installation time of the ground wire of the 10 kV switchgear.It used the correlation diagram to analyze prime problems and examine 6 terminal reasons. After analysis, it determined the fundamental reason is that the end of the conductor is difficult to fix because of the spiral force. This study drew lessons from the stripping spring structure and created a new type of ground wire of switchgear. The result shows that the new design significantly shortens the time of fixing the end of the conductor. The practical operation verifies that the improvement could help decrease the installation time of the ground wire of 10 kV switchgear.
Key words: switchgear; ground wire; spiral; spring structure
