本發明涉(she)及城市軌道交通(tong)系統領域，尤(you)其涉(she)及一(yi)種接觸網或接觸軌的放電裝置。

背景技術：

城市軌道交通一般采(cai)用直流750V或1500V接(jie)觸網(或接(jie)觸軌)供電(dian)。

接觸(chu)網(或接觸(chu)軌(gui))及(ji)其周邊設備(bei)停電后(hou)進行檢修維護時，為(wei)了保證作(zuo)(zuo)業人(ren)員人(ren)身安(an)全(quan)(quan)，需要采取(qu)“接地”的安(an)全(quan)(quan)措施，用接地線或接地刀閘將接觸(chu)網與(yu)回(hui)流軌(gui)短(duan)(duan)接，防止突然來(lai)電造(zao)成人(ren)員傷(shang)害。如果誤將帶有(you)正常工作(zuo)(zuo)電壓的接觸(chu)網與(yu)回(hui)流軌(gui)短(duan)(duan)接，會形成短(duan)(duan)路，造(zao)成接觸(chu)網設備(bei)損壞，并危及(ji)操(cao)(cao)作(zuo)(zuo)人(ren)員人(ren)身安(an)全(quan)(quan)。為(wei)避免短(duan)(duan)路，接觸(chu)網停電操(cao)(cao)作(zuo)(zuo)需要執行停電、驗電、放電、接地的操(cao)(cao)作(zuo)(zuo)過程。

接觸(chu)(chu)網(wang)停(ting)電(dian)(dian)后，在接觸(chu)(chu)網(wang)上(shang)仍(reng)會(hui)有殘(can)(can)(can)留電(dian)(dian)壓(ya)。殘(can)(can)(can)留電(dian)(dian)壓(ya)較高時(shi)，驗電(dian)(dian)結(jie)果會(hui)是“有電(dian)(dian)”，這種情(qing)況下，現場(chang)操作人員很難判斷接觸(chu)(chu)網(wang)上(shang)是殘(can)(can)(can)留電(dian)(dian)壓(ya)還是正常電(dian)(dian)壓(ya)。接觸(chu)(chu)網(wang)絕緣水平越高，殘(can)(can)(can)留電(dian)(dian)壓(ya)越高，殘(can)(can)(can)留電(dian)(dian)壓(ya)衰減越慢(man)，要等到驗電(dian)(dian)結(jie)果變(bian)成“無電(dian)(dian)”，可(ke)能要等幾十分鐘或(huo)者更長時(shi)間。

接(jie)(jie)觸(chu)(chu)網及其周邊設(she)備停(ting)電檢修一般安(an)(an)排在地(di)鐵(tie)夜間(jian)停(ting)運(yun)期間(jian)，作業(ye)時間(jian)只有(you)幾(ji)個小時，為(wei)避免接(jie)(jie)觸(chu)(chu)網殘壓衰減到(dao)“無電”的(de)(de)過程耗費太多時間(jian)，操(cao)(cao)作人(ren)員會(hui)根(gen)據現場運(yun)行狀況，在人(ren)工(gong)判斷(duan)接(jie)(jie)觸(chu)(chu)網電源已經斷(duan)開的(de)(de)情況下(xia)，直接(jie)(jie)用接(jie)(jie)地(di)線在接(jie)(jie)觸(chu)(chu)網與回流軌之間(jian)短(duan)接(jie)(jie)放電，之后執行接(jie)(jie)地(di)操(cao)(cao)作。這種操(cao)(cao)作具有(you)安(an)(an)全隱(yin)患，人(ren)工(gong)判斷(duan)失誤時，貿然將帶有(you)正(zheng)常工(gong)作電壓的(de)(de)接(jie)(jie)觸(chu)(chu)網對回流軌短(duan)接(jie)(jie)會(hui)造成(cheng)短(duan)路，造成(cheng)設(she)備損壞(huai)，并(bing)危及操(cao)(cao)作人(ren)員人(ren)身安(an)(an)全。
