結構與特性：
TBB系列自動投切裝置具備智能化的檢測控制性能，可適用于智能化無人值守變電站，其結構形式主要有戶外框架式、戶外預裝式（箱式）和戶內柜式三種。自動投切無功補償裝置是將原來1臺主變配置1組電容器實行整投整切的模式，改為由多組電容器不等（或等）容量調節投切模式。
控(kong)(kong)(kong)制(zhi)原理(li)以(yi)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)無(wu)功(gong)綜合(he)控(kong)(kong)(kong)制(zhi)為主，控(kong)(kong)(kong)制(zhi)器(qi)按照(zhao)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)和無(wu)功(gong)缺額的多少投(tou)切(qie)電(dian)(dian)(dian)(dian)容器(qi)。為防(fang)止(zhi)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)無(wu)功(gong)分離控(kong)(kong)(kong)制(zhi)可(ke)能造成的頻繁調(diao)(diao)節變壓(ya)(ya)(ya)(ya)器(qi)有載分接頭和頻繁投(tou)切(qie)電(dian)(dian)(dian)(dian)容器(qi)，防(fang)止(zhi)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)調(diao)(diao)節與電(dian)(dian)(dian)(dian)容投(tou)切(qie)的沖突，控(kong)(kong)(kong)制(zhi)器(qi)采用電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)無(wu)功(gong)綜合(he)自動控(kong)(kong)(kong)制(zhi)方案(an)。電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)無(wu)功(gong)綜合(he)控(kong)(kong)(kong)制(zhi)方案(an)采用二維模糊(hu)“十二區”控(kong)(kong)(kong)制(zhi)準(zhun)則。控(kong)(kong)(kong)制(zhi)的基本(ben)原則是 “保證電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)合(he)格，實(shi)現無(wu)功(gong)平衡(heng)，減少調(diao)(diao)節次數(shu)”。

功能特點：
1、跟蹤補償無功功率，不過補，不欠補，降低損耗，抑制系統諧波。
2、成套裝置采用模塊化設計原理，隨著負荷增加，允許追加補償模塊。
3、控制電容器組實現投切過程自動化、智能化、最優化，具備手動、自動、遙控三種控制模式。
4、可控制1-2段母線，2-8組電容，可綜合控制，也可獨立控制。
5、電容器組可等容分組，也可以根據用戶負荷變化情況組合不同容量。
6、單組電容器組配置獨立的保護單元，具備過壓、欠壓、過流、速斷、不平衡電壓保護。
7、控制器具備閉鎖、自診斷及現場參數設置等功能。
8、電容器專用真空投切開關體積小，重量輕，壽命長，無重燃等優點。
9、成套裝置具備快速放電、限制合閘涌流和操作過電壓等功能。
10、戶內柜式(shi)和戶外預裝式(shi)結構占地面積小，安裝方便，裝設智能化(hua)檢(jian)測(ce)控制模塊，并可遠(yuan)程檢(jian)測(ce)裝置運行狀況(kuang)。
