微機消諧裝置行業簡介

一、微機消諧裝置有什么作用

微機消(xiao)諧裝置用于高壓(ya)(ya)柜，是用來保護高壓(ya)(ya)的PT設備(bei)，可有(you)效防止諧振擊(ji)穿電壓(ya)(ya)互感器(qi)。有(you)6kV，10kV，35kV等等。

微(wei)機(ji)消(xiao)諧裝置可以防(fang)止電(dian)(dian)(dian)壓互感器(qi)發生(sheng)鐵(tie)磁諧振，擊穿(chuan)電(dian)(dian)(dian)壓互感器(qi)的惡性事故，影響正常的生(sheng)產和(he)(he)事故。微(wei)機(ji)消(xiao)諧利用高性能(neng)單片(pian)機(ji)檢測(ce)和(he)(he)控(kong)制，使用固態繼(ji)電(dian)(dian)(dian)器(qi)，電(dian)(dian)(dian)流大(da)，動作可靠。

二、微機消諧裝置工作原理是什么

微(wei)機(ji)消(xiao)諧(xie)裝(zhuang)置(zhi)采用高性(xing)能的(de)(de)單片(pian)微(wei)機(ji)作為(wei)核心元件，對(dui)PT開(kai)(kai)口三角電(dian)(dian)(dian)(dian)(dian)壓(ya)（即零(ling)序電(dian)(dian)(dian)(dian)(dian)壓(ya)）進行遁環檢(jian)測(ce)。正常工作情況下(xia)，該電(dian)(dian)(dian)(dian)(dian)壓(ya)小于30V，裝(zhuang)置(zhi)內(nei)的(de)(de)大(da)功(gong)率消(xiao)諧(xie)元件（固(gu)態(tai)繼電(dian)(dian)(dian)(dian)(dian)器(qi)）處于阻斷狀態(tai)，對(dui)系統(tong)(tong)(tong)(tong)(tong)(tong)運行不產(chan)生影響(xiang)。當PT開(kai)(kai)口電(dian)(dian)(dian)(dian)(dian)壓(ya)大(da)于30V時，系統(tong)(tong)(tong)(tong)(tong)(tong)出現故(gu)障。消(xiao)諧(xie)裝(zhuang)置(zhi)開(kai)(kai)始對(dui)此信號(hao)(hao)進行數(shu)據采集，通過(guo)電(dian)(dian)(dian)(dian)(dian)路(lu)對(dui)信號(hao)(hao)進行數(shu)字測(ce)量、濾波(bo)、放大(da)等數(shu)字信號(hao)(hao)處理(li)技術，然后對(dui)檢(jian)測(ce)到(dao)的(de)(de)數(shu)據進行分(fen)析、計算，得出故(gu)障類型。如果當前是鐵(tie)磁諧(xie)振，系統(tong)(tong)(tong)(tong)(tong)(tong)立即啟動(dong)消(xiao)諧(xie)電(dian)(dian)(dian)(dian)(dian)路(lu)，使固(gu)態(tai)繼電(dian)(dian)(dian)(dian)(dian)器(qi)導(dao)通，讓鐵(tie)磁諧(xie)振在(zai)阻尼作用下(xia)迅速消(xiao)失。此時，CPU系統(tong)(tong)(tong)(tong)(tong)(tong)進行記(ji)錄(lu)、存貯，并(bing)自動(dong)報警、顯(xian)示諧(xie)振信息（時間(jian)、頻率、電(dian)(dian)(dian)(dian)(dian)壓(ya)值）。如果電(dian)(dian)(dian)(dian)(dian)路(lu)是過(guo)電(dian)(dian)(dian)(dian)(dian)壓(ya)或單相(xiang)接地故(gu)障，微(wei)機(ji)系統(tong)(tong)(tong)(tong)(tong)(tong)檢(jian)測(ce)后，分(fen)別(bie)給出顯(xian)示和報警，并(bing)記(ji)錄(lu)、存貯有(you)關故(gu)障信息。CPU系統(tong)(tong)(tong)(tong)(tong)(tong)處理(li)完(wan)最后，返回起始狀態(tai)，并(bing)繼續檢(jian)測(ce)電(dian)(dian)(dian)(dian)(dian)路(lu)中的(de)(de)狀態(tai)。

三、微機消諧裝置的常見故障介紹

微(wei)機消(xiao)諧裝置(zhi)在(zai)實際運行中(zhong)，會(hui)出(chu)現諧振(zhen)報(bao)警，首先(xian)應分析(xi)具(ju)體情況，輔助其他措(cuo)施，才能得出(chu)結(jie)論，從根源上解決問題。微(wei)機消(xiao)諧裝置(zhi)廠家介紹在(zai)正常工(gong)作條件時，電壓小于30V裝置(zhi)中(zhong)大功率固態(tai)繼電器的(de)(de)閉鎖狀態(tai)，不會(hui)影(ying)響系統的(de)(de)正常運行。當電壓大于30V時，系統將出(chu)現故障(zhang)，微(wei)機將采集數(shu)據(ju)。

通過(guo)電路(lu)對信號進(jin)(jin)行(xing)(xing)測量和分析，并(bing)(bing)對數(shu)字信號處理(li)技術(shu)進(jin)(jin)行(xing)(xing)濾(lv)波和放(fang)大(da)。然(ran)后對檢(jian)測到的數(shu)據進(jin)(jin)行(xing)(xing)分析計算，得出故障(zhang)類型。如果得出的故障(zhang)是鐵磁諧振，此時微機消諧裝置啟動(dong)，固態繼電器在阻尼作用(yong)下使鐵磁諧振迅速(su)消除。同(tong)時系統將自(zi)動(dong)記(ji)錄、存儲和報警數(shu)據，并(bing)(bing)顯(xian)示共振信息。
