id="5hlvxzllpl3" class="page-procon"> <p><strong>一、概述</strong></p><p> </p><p> 當(dāng)前電力系統(tǒng)直流電源接地故障查找的核心問題是現(xiàn)場(chǎng)干擾大，在不同的直流電源和不同的工作狀態(tài)下測(cè)量，絕大部分產(chǎn)品會(huì)誤測(cè)誤判，抗干擾性差，我們的產(chǎn)品之所以迅速立足該市場(chǎng)，是因?yàn)槌晒鉀Q了干擾問題。WZJ-B型便攜式直流系統(tǒng)接地故障定位儀，采用正弦信號(hào)相位超前處理技術(shù)和數(shù)據(jù)轉(zhuǎn)移算法技術(shù)（技術(shù)）研制生產(chǎn)。本產(chǎn)品介于固定式和移動(dòng)式兩大類型之間，使用方法為移動(dòng)式，性能為在線固定式，查找直流系統(tǒng)接地故障時(shí)，不需要斷開電源，可實(shí)現(xiàn)接地點(diǎn)定位。儀器能準(zhǔn)確檢測(cè)直流系統(tǒng)接地電阻阻值，為電力直流系統(tǒng)接地故障的查尋與定位提供適用可靠的高準(zhǔn)確性探測(cè)儀器。</p><p> </p><p><strong>二、功能及特點(diǎn)</strong></p><p> </p><p> 1、本儀器分信號(hào)發(fā)送器和信號(hào)接收器,信號(hào)發(fā)送器(檢測(cè)母線接地電阻用)直接從母線上取電,不須外接交流電源或電池充電,使用更加方便。</p><p> 2、110V、220V直流系統(tǒng)共用一套直流接地探測(cè)器(24V、48V可以特殊訂制)。</p><p> 3、可以*排除直流系統(tǒng)接地故障,現(xiàn)場(chǎng)分布大電容的干擾,準(zhǔn)確無(wú)誤地將故障鎖定在zui小范圍內(nèi)。</p><p> 4、測(cè)量準(zhǔn)確率:100%。<br /> 5、信號(hào)輸出功率：＜0.15W,內(nèi)設(shè)限流保護(hù)，對(duì)繼電保護(hù)、自動(dòng)、操作回路沒有影響，使用安全。<br /> 6、信號(hào)頻率穩(wěn)定度：±0.02Hz。</p><p> 7、采用“心”型設(shè)計(jì)的鉗口，大、小線共用，不用換鉗子。<br /> 8、能適應(yīng)交、直流串電引起的接地，環(huán)網(wǎng)供電接地，二極管隔離供電接地，高阻接地。<br /> 9、不用安裝，不用停電，不用搖絕緣，就能快速準(zhǔn)確找到一點(diǎn)或多點(diǎn)接地位置。<br /> 10、豪華外包裝，攜帶方便。</p><p> </p><p><strong>三、技術(shù)參數(shù)</strong></p><p>
