10KV高壓(ya)(ya)無(wu)(wu)功(gong)(gong)補償裝(zhuang)置(MSCHA型)是一(yi)種用于根據(ju)配電(dian)(dian)(dian)(dian)變壓(ya)(ya)器的(de)(de)無(wu)(wu)功(gong)(gong)負荷情況(kuang)自動進(jin)行分步投切，并聯在配電(dian)(dian)(dian)(dian)變壓(ya)(ya)器3~20kV母(mu)線上的(de)(de)電(dian)(dian)(dian)(dian)容(rong)(rong)器組的(de)(de)設(she)備(bei)，其(qi)主(zhu)要功(gong)(gong)能是提(ti)供(gong)相應的(de)(de)容(rong)(rong)性無(wu)(wu)功(gong)(gong)功(gong)(gong)率。這個裝(zhuang)置的(de)(de)設(she)計突破了(le)原電(dian)(dian)(dian)(dian)力系(xi)統(tong)中電(dian)(dian)(dian)(dian)容(rong)(rong)器組整體(ti)投入造成過度(du)補償的(de)(de)問題，以及(ji)切除(chu)后母(mu)線無(wu)(wu)功(gong)(gong)功(gong)(gong)率不足的(de)(de)情況(kuang)。它能夠顯(xian)著提(ti)高母(mu)線功(gong)(gong)率因數，并使(shi)其(qi)能夠穩定在一(yi)定水平，從(cong)而穩定了(le)系(xi)統(tong)電(dian)(dian)(dian)(dian)壓(ya)(ya)，提(ti)高了(le)變壓(ya)(ya)器的(de)(de)利用率。該裝(zhuang)置主(zhu)要由(you)以下(xia)組件構成：并聯電(dian)(dian)(dian)(dian)容(rong)(rong)器、串聯電(dian)(dian)(dian)(dian)抗器、電(dian)(dian)(dian)(dian)壓(ya)(ya)互感器、避雷器、投切設(she)備(bei)、控制和保護裝(zhuang)置等。

這個10KV高壓無功補償裝置(MSCHA型)采(cai)用(yong)了單(dan)元積(ji)木式設(she)計，各(ge)個柜體之(zhi)間使(shi)用(yong)硬母排聯接，這樣可以(yi)保證運行(xing)的可靠性，并且可以(yi)通(tong)過增加柜體數量來擴展(zhan)容量。在各(ge)種(zhong)工況(kuang)下(xia)(xia)，每套裝置都需要進(jin)行(xing)諧振校驗，這包括選擇(ze)適(shi)當的容量，以(yi)避開諧振放大區域，或者選擇(ze)適(shi)當的電抗(kang)率，以(yi)確保在各(ge)種(zhong)工況(kuang)下(xia)(xia)都能夠安全(quan)運行(xing)。

此外，這個10KV高壓無(wu)功(gong)(gong)(gong)補償裝(zhuang)(zhuang)置(zhi)(MSCHA型)還(huan)配備了(le)先進的無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)控制器，它能(neng)夠(gou)實(shi)(shi)時在線(xian)監測系統(tong)的無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)因數，并實(shi)(shi)時跟蹤投切操作(zuo)。根據用(yong)戶(hu)需求(qiu)，還(huan)可以配備RS232/485通訊(xun)接口，以將整(zheng)個裝(zhuang)(zhuang)置(zhi)的運行數據上傳(chuan)至監控系統(tong)。此外，為了(le)確保(bao)安全性(xing)，裝(zhuang)(zhuang)置(zhi)還(huan)設有過(guo)流(liu)保(bao)護，使用(yong)了(le)噴(pen)逐(zhu)式(shi)熔(rong)斷器或內熔(rong)絲(si)，以及零序電(dian)壓保(bao)護功(gong)(gong)(gong)能(neng)。
