有載調容調壓開關由于變壓(ya)器損(sun)失率(lv)ΔP%與負(fu)載系數β特性(xing)是一(yi)個(ge)非線性(xing)函數,所以,如圖中可按(an)損(sun)失率(lv)的大小分成三個(ge)運行區(qu):經濟運行區(qu),不良(liang)運行區(qu)和(he)最(zui)劣運行區(qu)。

從圖中可以看出當(dang)變壓(ya)(ya)器(qi)(qi)輕載、滿載時(shi),變壓(ya)(ya)器(qi)(qi)工作(zuo)在不良運行(xing)區(qu);當(dang)變壓(ya)(ya)器(qi)(qi)空(kong)載時(shi),變壓(ya)(ya)器(qi)(qi)工作(zuo)在最劣(lie)運行(xing)區(qu)。

油(you)(you)(you)田配電(dian)網(wang)的(de)主(zhu)要設備(bei)是抽(chou)油(you)(you)(you)機,抽(chou)油(you)(you)(you)機用電(dian)負(fu)荷變化(hua)明顯(xian),一般最高負(fu)荷都出現在(zai)抽(chou)油(you)(you)(you)機啟動時,然(ran)后負(fu)荷隨著液量、黏度等不同,不斷變化(hua)。啟動后用電(dian)較少,安(an)裝(zhuang)的(de)變壓(ya)器(qi)容量是按(an)抽(chou)油(you)(you)(you)機起動時的(de)負(fu)荷來(lai)選擇(ze)的(de),而(er)變壓(ya)器(qi)本身(shen)的(de)損(sun)耗是隨容量的(de)增大而(er)增加(jia)的(de)。抽(chou)油(you)(you)(you)機起動過后,變壓(ya)器(qi)經常處(chu)于輕(qing)載和空載狀態,“大馬拉小車(che)”,造成電(dian)能浪費。

有載自動(dong)調(diao)容(rong)(rong)配電(dian)變(bian)(bian)壓(ya)(ya)器(qi)可根據(ju)用戶負荷大小(xiao)由自動(dong)調(diao)容(rong)(rong)控制器(qi)自動(dong)檢測判斷(duan)，并通過(guo)特制的有載調(diao)容(rong)(rong)開關，在變(bian)(bian)壓(ya)(ya)器(qi)不(bu)停電(dian)狀態(tai)的下，對變(bian)(bian)壓(ya)(ya)器(qi)兩(liang)種(zhong)容(rong)(rong)量進行自動(dong)切換(huan)，實(shi)現對運行過(guo)程中變(bian)(bian)壓(ya)(ya)器(qi)容(rong)(rong)量大小(xiao)自動(dong)調(diao)整(zheng)，從而實(shi)現兩(liang)種(zhong)額定容(rong)(rong)量運行方式自動(dong)轉換(huan)。合理配置配電(dian)變(bian)(bian)壓(ya)(ya)器(qi)容(rong)(rong)量，使(shi)之與用電(dian)負荷相(xiang)適應，能(neng)有效解決(jue)當前環(huan)縣(xian)農村配網亟(ji)待解決(jue)的問題。同時，能(neng)夠有效節能(neng)降耗、降低網損，減少(shao)不(bu)必要的浪費。

據(ju)介紹(shao)，該產品采(cai)用智(zhi)能調容(rong)(rong)調壓(ya)(ya)控(kong)制系統、低溫升(sheng)設計(ji)、Zigbee無線“四遙”與配電監測等(deng)關(guan)鍵(jian)技(ji)術，具有大(da)小(xiao)兩(liang)種(zhong)(zhong)額定(ding)容(rong)(rong)量，根據(ju)用戶(hu)所帶負荷(he)大(da)小(xiao)由自動(dong)調容(rong)(rong)控(kong)制器(qi)自動(dong)檢(jian)測判斷，并通(tong)過(guo)特制的(de)(de)(de)有載調容(rong)(rong)開關(guan)，在變(bian)壓(ya)(ya)器(qi)不停電狀態下，對(dui)(dui)變(bian)壓(ya)(ya)器(qi)兩(liang)種(zhong)(zhong)容(rong)(rong)量進(jin)行(xing)自動(dong)切(qie)換(huan)，實現(xian)對(dui)(dui)運行(xing)過(guo)程中變(bian)壓(ya)(ya)器(qi)容(rong)(rong)量大(da)小(xiao)自動(dong)調整，從而(er)實現(xian)兩(liang)種(zhong)(zhong)額定(ding)容(rong)(rong)量運行(xing)方式自動(dong)轉換(huan)的(de)(de)(de)配電變(bian)壓(ya)(ya)器(qi)，并根據(ju)電壓(ya)(ya)變(bian)化(hua)自動(dong)調壓(ya)(ya)，在保(bao)證(zheng)智(zhi)能節能的(de)(de)(de)同時，進(jin)一步提升(sheng)了產品的(de)(de)(de)可靠性。有載調容(rong)(rong)調壓(ya)(ya)開關(guan)
