交直流試驗(yàn)的切換
1)本儀器高壓輸出為交流電壓。直流的獲得方式為在原回路中串入高壓硅堆,使測(cè)試回路為脈動(dòng)的直流電壓。實(shí)現(xiàn)的過程為,硅堆已經(jīng)在高壓變壓器的高壓絕緣塔中,平時(shí)用一個(gè)短路桿把高壓硅堆短接。需要直流試驗(yàn)時(shí),取出短路桿,使高壓硅堆接入測(cè)試電路中,這時(shí)回路的電壓為脈動(dòng)的直流電壓。
2)前面板直流交流選擇按鈕。該按鈕的狀態(tài)不能改變?cè)O(shè)備輸出的電壓性質(zhì)。按下該按鈕,設(shè)備僅僅是把直流報(bào)警電路接入。指示用戶,當(dāng)打開箱門時(shí),您需要對(duì)高壓均壓球放電。轉(zhuǎn)動(dòng)放電桿,使放電桿的端部銅球接觸高壓均壓球。建議用戶每次放電銅球接觸高壓均壓球時(shí)間大于五秒。
3)試驗(yàn)的交直流電壓切換,主要取決于高壓絕緣塔中的短路桿是否取出。當(dāng)取出短路桿時(shí),高壓均壓球上的電壓為直流電壓,插入短路桿時(shí),高壓均壓球上的電壓為交流電壓。短路桿的取出、插入?yún)⒖醋髠?cè)的示意圖。
4)在直流試驗(yàn)時(shí),計(jì)算機(jī)也要選擇直流狀態(tài),否則測(cè)的結(jié)果是不正確的。簡(jiǎn)單的說,交流電壓與直流電壓有倍的關(guān)系。
