總之，我國(guo)550KV高壓開(kai)(kai)關設備有大的發展空間(jian)。據電(dian)(dian)力(li)部門(men)提供的資料，2003年(nian)電(dian)(dian)力(li)系統(tong)裝備550KVSF6斷(duan)路(lu)器(qi)(qi)164臺，而2003年(nian)高壓開(kai)(kai)關行業(ye)才生產(chan)(chan)73臺，2004年(nian)也只有77臺（不包括外(wai)資及(ji)合資企(qi)業(ye)），缺口基本為外(wai)國(guo)產(chan)(chan)品所(suo)填補。550KVGIS的產(chan)(chan)量(liang)更少，變頻器(qi)(qi)生產(chan)(chan)，2003年(nian)僅生產(chan)(chan)4間(jian)隔(ge)，由于國(guo)內(nei)能力(li)及(ji)裝備政策關系，三峽左岸(an)39間(jian)隔(ge)550KVGIS全部被ABB公司中標。550KVGIS反映(ying)了(le)一個企(qi)業(ye)的綜合生產(chan)(chan)能力(li)，它是附加值很(hen)高的高科技產(chan)(chan)品。

高壓超高壓領域是國內企業提高占有率的一個重要方面。超高壓部分市場上升空間大，技術含量高，現已有引進消化的基礎，需要加大研制力度，提高技術水平，爭取在斷路器、GIS和混合技術開關設備產品方面擴大市場占有率。

基本分類(lei)單元(yuan)串聯型變頻器(qi)

利(li)德華福高壓(ya)變頻器(qi)再創(chuang)新這是近(jin)幾(ji)年才發展起來的(de)(de)一種電(dian)(dian)路拓撲結構，它主要由輸入(ru)變壓(ya)器(qi)、功(gong)率單元(yuan)和控制單元(yuan)三大(da)部分組成。采用模塊化設計，由于采用功(gong)率單元(yuan)相互(hu)串聯的(de)(de)辦法解決了高壓(ya)的(de)(de)難題而得(de)名，可(ke)直接驅(qu)動交流電(dian)(dian)動機，無(wu)需輸出變壓(ya)器(qi)，更不需要任何(he)形式的(de)(de)濾波器(qi)。

該變頻(pin)器(qi)的特(te)點如下：

① 采用多重化(hua)PWM方(fang)式控制，輸出電壓(ya)波形接近(jin)正弦波。

② 整流電路的(de)多(duo)重化，脈(mo)沖數(shu)多(duo)達36，功率因(yin)數(shu)高，輸入諧波小(xiao)。

③ 模塊化(hua)設計，結(jie)構緊(jin)湊(cou)，維護方便，增強了(le)產(chan)品(pin)的互換性(xing)。

④ 直(zhi)接高壓輸出，無需輸出變壓器。

⑤ 極低的dv/dt輸出，無需任何形(xing)式的濾(lv)波器(qi)。

⑥ 采用光纖通訊(xun)技術(shu)，提高了產品的抗(kang)干(gan)擾能力和可靠性。

⑦ 功率單元自動旁通電路，能夠實現故障不停機功能。

同整流器(qi)相(xiang)反，逆變器(qi)是(shi)將直流功率(lv)變換為(wei)所要求頻率(lv)的交(jiao)流功率(lv)，以(yi)所確定的時間使6個(ge)開關(guan)器(qi)件導(dao)通、關(guan)斷就可以(yi)得到3相(xiang)交(jiao)流輸出(chu)。以(yi)電壓(ya)(ya)型pwm逆變器(qi)為(wei)例示出(chu)開關(guan)時間和電壓(ya)(ya)波(bo)形。

控(kong)制(zhi)電(dian)(dian)路(lu)(lu)(lu)(lu)是給異步電(dian)(dian)動機供(gong)電(dian)(dian)（電(dian)(dian)壓、頻率可調）的(de)主(zhu)電(dian)(dian)路(lu)(lu)(lu)(lu)提供(gong)控(kong)制(zhi)信號的(de)回路(lu)(lu)(lu)(lu)，它有頻率、電(dian)(dian)壓的(de)“運算電(dian)(dian)路(lu)(lu)(lu)(lu)”，主(zhu)電(dian)(dian)路(lu)(lu)(lu)(lu)的(de)“電(dian)(dian)壓、電(dian)(dian)流檢測(ce)電(dian)(dian)路(lu)(lu)(lu)(lu)”，電(dian)(dian)動機的(de)“速度檢測(ce)電(dian)(dian)路(lu)(lu)(lu)(lu)”，將運算電(dian)(dian)路(lu)(lu)(lu)(lu)的(de)控(kong)制(zhi)信號進行放大的(de)“驅動電(dian)(dian)路(lu)(lu)(lu)(lu)”，以及逆變(bian)器和電(dian)(dian)動機的(de)“保護(hu)電(dian)(dian)路(lu)(lu)(lu)(lu)”組成。

（1）運算電(dian)(dian)(dian)路：將外部(bu)的(de)(de)(de)速度、轉矩等指令同檢測電(dian)(dian)(dian)路的(de)(de)(de)電(dian)(dian)(dian)流、電(dian)(dian)(dian)壓(ya)信號進(jin)行比較(jiao)運算，決定(ding)逆變器的(de)(de)(de)輸出電(dian)(dian)(dian)壓(ya)、頻率(lv)。

（2）電(dian)(dian)壓、電(dian)(dian)流(liu)檢測(ce)電(dian)(dian)路：與主回路電(dian)(dian)位(wei)隔離檢測(ce)電(dian)(dian)壓、電(dian)(dian)流(liu)等。

（3）驅(qu)動(dong)電(dian)路(lu)(lu)：驅(qu)動(dong)主(zhu)電(dian)路(lu)(lu)器件的電(dian)路(lu)(lu)。它與控制電(dian)路(lu)(lu)隔離使主(zhu)電(dian)路(lu)(lu)器件導通、關(guan)斷(duan)。

（4）速(su)(su)度檢測(ce)電(dian)路(lu):以裝在異步電(dian)動機軸(zhou)機上的速(su)(su)度檢測(ce)器(tg、plg等(deng))的信號(hao)為速(su)(su)度信號(hao)，送(song)入(ru)運算(suan)回路(lu)，根據指(zhi)令和運算(suan)可(ke)使電(dian)動機按(an)指(zhi)令速(su)(su)度運轉。

（5）保護電(dian)路：檢(jian)測主電(dian)路的電(dian)壓(ya)、電(dian)流(liu)等，當發生過(guo)載或過(guo)電(dian)壓(ya)等異常(chang)時(shi)，為(wei)了防止逆變器和異步電(dian)動機損(sun)壞，使(shi)逆變器停止工作或抑(yi)制電(dian)壓(ya)、電(dian)流(liu)值。
