根據現行國家標準《并(bing)聯電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)裝置設計規范》GB 50227，因電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)參數(shu)的(de)分散(san)性，其配(pei)套設備的(de)額定電(dian)(dian)(dian)(dian)流(liu)按(an)大于電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)組額定電(dian)(dian)(dian)(dian)流(liu)的(de)1.35倍(bei)(bei)考(kao)慮(lv)。由(you)于投(tou)入(ru)電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)時(shi)(shi)合閘(zha)涌流(liu)甚大，而且容(rong)(rong)(rong)(rong)量愈小，相對(dui)的(de)涌流(liu)倍(bei)(bei)數(shu)愈大，以1000kV·A變壓器(qi)低壓側(ce)安裝的(de)電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)組為例，僅投(tou)切一(yi)臺12kvar電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)則(ze)(ze)涌流(liu)可達(da)其額定電(dian)(dian)(dian)(dian)流(liu)的(de)56.4倍(bei)(bei)，如投(tou)切一(yi)組300kvar電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)，則(ze)(ze)涌流(liu)僅為其額定電(dian)(dian)(dian)(dian)流(liu)的(de)12.4倍(bei)(bei)。所以電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)在分組時(shi)(shi)，應(ying)考(kao)慮(lv)配(pei)套設備，如接觸器(qi)或自動開(kai)關在開(kai)斷(duan)電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)時(shi)(shi)產生(sheng)重擊穿過電(dian)(dian)(dian)(dian)壓及(ji)電(dian)(dian)(dian)(dian)弧重擊穿現象。
