電源的抗干擾設計

據工程統計數(shu)據分(fen)析，正(zheng)泰(tai)電(dian)(dian)(dian)(dian)流(liu)表(biao)(biao)(biao)(biao)廠家，電(dian)(dian)(dian)(dian)力(li)儀表(biao)(biao)(biao)(biao)系統70%的(de)(de)干擾都是(shi)通過電(dian)(dian)(dian)(dian)源(yuan)耦合進入系統的(de)(de)。因此，電(dian)(dian)(dian)(dian)源(yuan)供(gong)電(dian)(dian)(dian)(dian)質(zhi)量的(de)(de)提(ti)高對整(zheng)個系統的(de)(de)可(ke)靠(kao)運行有(you)(you)著十分(fen)重(zhong)要的(de)(de)意(yi)義(yi)。由于系統的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)一般都是(shi)由市電(dian)(dian)(dian)(dian)轉(zhuan)換得到，江蘇正(zheng)泰(tai)電(dian)(dian)(dian)(dian)流(liu)表(biao)(biao)(biao)(biao)，所以電(dian)(dian)(dian)(dian)源(yuan)部分(fen)的(de)(de)抗干擾設(she)計主要集中在電(dian)(dian)(dian)(dian)源(yuan)輸入端口的(de)(de)濾波(bo)和(he)瞬態干擾的(de)(de)抑(yi)(yi)制方面。圖1是(shi)電(dian)(dian)(dian)(dian)源(yuan)抗干擾的(de)(de)一個典型設(she)計，其中，正(zheng)泰(tai)電(dian)(dian)(dian)(dian)流(liu)表(biao)(biao)(biao)(biao)哪家好，RV1為(wei)(wei)熱敏電(dian)(dian)(dian)(dian)阻，VZ1為(wei)(wei)壓敏電(dian)(dian)(dian)(dian)阻，LA1為(wei)(wei)共模(mo)扼(e)流(liu)圈。該電(dian)(dian)(dian)(dian)路(lu)可(ke)以有(you)(you)效抑(yi)(yi)制浪涌和(he)群脈沖干擾。
