【技術(shù)實現(xiàn)步驟摘要】
本專利技術(shù)涉及電力設(shè)備
,具體說是一種防雷線路柱式復(fù)合絕緣子。
技術(shù)介紹
目前的一種防雷支柱復(fù)合絕緣子,將支柱絕緣子和防弧金具合二為一,如中國專利公開號CN101325104B,其結(jié)構(gòu)包括絕緣護罩和設(shè)置絕緣護罩內(nèi)的由上壓塊和下壓塊構(gòu)成的夾線金具,該夾線金具側(cè)端連接引弧棒,且該夾線金具下端連接絕緣子,絕緣子外套設(shè)有防污傘群。絕緣子下端設(shè)置下鋼腳,并且引弧棒的下端靠近下鋼腳設(shè)置。但是這種結(jié)構(gòu)的防雷支柱絕緣子存在以下缺陷:1.夾線金具的上壓塊和下壓塊才用壓緊螺母和備緊螺母老夾緊和穿刺導(dǎo)線,為了防止上壓塊和下壓塊的夾緊穿刺導(dǎo)線的過程中,損傷導(dǎo)線,需要根據(jù)導(dǎo)線的截面及天氣溫溫度等因素來設(shè)定一個范圍的扳手扭力,而在實際操作過程中,經(jīng)常因為工人的操作誤差,扳手扭力過大或過小,而導(dǎo)致導(dǎo)線在夾緊過程中受損或?qū)Ь€沒有達到最佳的接觸效果,嚴重影響防雷支柱絕緣子的性能;2.防污傘群結(jié)構(gòu)設(shè)置不合理,其背面為水平設(shè)計,在使用過程中,防污傘群的背面往往會堆積灰塵等污垢,但是在雨水天氣的時候,該水平設(shè)計的防污傘群背面結(jié)構(gòu)無法將雨水引流到防污傘群的背面,對污垢的沖刷,防污能力較差。3.在滿足爬距條件下,傘徑過大易造成傘裙和引弧棒耐工頻濕閃水平不足。為了解決上述技術(shù)問題,中國專利申請?zhí)?01220202149.4公開了另外一種一種防雷線路柱式復(fù)合絕緣子,“包括絕緣護罩和設(shè)置于所述絕緣護罩內(nèi)由上壓塊和下壓塊構(gòu)成的夾線金具,所述夾線金具側(cè)端連接引弧棒,且所述夾線金具下端連接絕緣子,所述絕緣子下端設(shè)置下鋼腳,并且所述引弧棒的下端靠近所述下鋼腳設(shè)置,其特征在于:所述上壓塊和所述下壓塊通過螺栓 ...
【技術(shù)保護點】
一種可調(diào)放電距離的防雷線路柱式復(fù)合絕緣子,包括絕緣護罩和設(shè)置于所述絕緣護罩內(nèi)由上壓塊和下壓塊構(gòu)成的夾線金具,所述下壓塊側(cè)端連接引弧棒的連接部,且所述下壓塊連接絕緣子,所述絕緣子下端設(shè)置下鋼腳,并且所述引弧棒的下端靠近所述下鋼腳,其特征在于:所述引弧棒與下壓塊間為軸接,下壓塊側(cè)端設(shè)置半球形凸部,引弧棒的連接部設(shè)置相應(yīng)形成的半球形凹部,轉(zhuǎn)軸穿過所述凸部嵌入所述凹部兩側(cè)的軸孔中;下壓塊上部的軸部外側(cè)設(shè)置限位螺母,所述限位螺母與引弧棒抵接;所述引弧棒的端部外側(cè)設(shè)置螺紋,所述螺紋旋入接口螺套中,固定螺母設(shè)置在所述螺紋上并與接口螺套緊密接觸。
