屏蔽線接地方法及原理
UL電(dian)(dian)(dian)子線屏蔽線的(de)一(yi)端(duan)接(jie)(jie)地(di)(di)(di)，另(ling)(ling)一(yi)端(duan)懸空。當信號(hao)線傳輸距離比較遠的(de)時候，由于兩(liang)端(duan)的(de)接(jie)(jie)地(di)(di)(di)電(dian)(dian)(dian)阻不同或PEN線有電(dian)(dian)(dian)流，可能(neng)會導致兩(liang)個接(jie)(jie)地(di)(di)(di)點電(dian)(dian)(dian)位不同，此時如果(guo)兩(liang)端(duan)接(jie)(jie)地(di)(di)(di)，屏蔽層就有電(dian)(dian)(dian)流行成，反而對信號(hao)形成干擾(rao)(rao)，因此這種(zhong)情況下一(yi)般采取一(yi)點接(jie)(jie)地(di)(di)(di)，另(ling)(ling)一(yi)端(duan)懸空的(de)辦法，能(neng)避免此種(zhong)干擾(rao)(rao)形成。兩(liang)端(duan)接(jie)(jie)地(di)(di)(di)屏蔽效果(guo)更
