c的上部及母線區劃部1 a的交界部， 是如第3圖所示設置區劃用的板5。在母線區劃部1 a內， 3相的固體絕緣的母線6是通過連接用套筒6 a與框體1的 前面平行（第1圖中與紙面垂直的方向）配置。母線6，是 藉由固體絕緣，被無氣體化，來確保使用性及安全性。 開閉器區劃部1 b，在此例中是將真空2切點3位置開 啓模閉器（真空2切點3位置型遮斷斷路器）、接地開閉器 及操作裝置框體組裝成組件，當零件交換、維修時從框體 1搬出。此詳細的說明，是使用第5圖乃至第7圖說明。 在纜線區劃部1 c中，設有：連接於真空2切點3位 置開啓模閉器（真空2切點3位置型遮斷斷路器）的固定接 點供被導入纜線區劃部1 c內的纜線連接用的端子、及可 旋轉地設在此端子的T型拉索接頭、及藉由此T型拉索接 頭連接於端子的2條纜線、及設在端子外周的系統保護用

頂板3的凸緣3 a，下部側板8的下部是由螺絲固定於底板 2的凸緣2 a。上部側板7的下部，是由螺絲固定於與第1 -9- 200839825 中間側板9上部的各凸緣的抵接面，第1中間側板9的下 部，是由螺絲固定於與第2中間側板1 0上部的各凸緣的 抵接面，且，第2中間側板1 0的下部，是由螺絲固定於 與下部側板8的上部的各凸緣的抵接面。第1中間側板9 ，是如後述，藉由螺絲可裝卸地安裝在組件化的開閉器區 劃部1 b的框體的正面門側的側部。 構成低電壓控制區劃部1 d的正面門1 e，是藉由：可 裝卸地設在一方的第1中間側板9(第3圖的右側）的具有 轉動功能之第1鉸鏈1 1、及各別設在一方的上部側板7( 第3圖的右側）及一方的下部側板8(第3圖的右側）的具有 轉動及滑動（朝框體1的前後方向移動）功能的第2鉸鏈1 2 ，成爲可開閉動作。第2鉸鏈1 2，是如第8圖及第9圖所 示，藉由解除第1鉸鏈1 1的朝第1中間側板9的固定， 而將正面門1 e朝框體1的前後方向移動，並且框體1的 開方向（第8圖的右方向，第9圖的上方向）的移動量變大 ，具有可確保開閉器區劃部1 b的朝框體1的前方的拉出 用的開口空間的功能。 回到第1圖及第3圖，在低電壓控制區劃部1 d中， 如第3圖所示的低電壓控制部1 dc、保護繼電器1 dab是安 裝被於正面門1 e的背面。在正面門1 e的正面中，如第1 圖所示，從上朝下依序配置：顯示接地/短路事故、電容 器異常、真空壓異常等的警報顯示部1 ea、及各種的操作 開關部1 eb、及緊急用手動操作桿操作部1 ec。 在警報顯示部1 ea中，例如設置：顯示接地/短路的事 -10- 200839825 故的顯示部、內部鎖定的有効/無效的顯示部、電容器異 常顯示部、真空壓力異常顯示部、電容器充電完成顯示部 等。且’在操作開關部1 e b中，例如設置：真空2切點3 位置開啓模閉器及接地開閉器的操作切換開關、遠/直切 換開關、真空2切點3位置開啓模閉器的入/切/斷路的操 作開關、真空2切點3位置開啓模閉器的位置顯示燈泡、 真空2切點3位置開啓模閉器的機械位置顯示部、接地開 閉器的接地/切的操作開關，接地開閉器的機械地位置顯 示部，及檢電、檢相用的端子等。 接著’使用第5圖乃至第7圖說明前述組件化開閉器 區劃部1 b的結構。 開閉器區劃部1 b，在此例中雖是將真空2切點3位置 開啓模閉器（真空2切點3位置型遮斷斷路器）、接地開閉 器及操作裝置組裝於框體的組件，但是配置於開閉器區劃 部1 b內的真空2切點3位置開啓模閉器1 3、接地開閉器 1 4 ’是藉由如第7圖所示的環氧樹脂一體地被塑模。由此 ’開閉器部被組件化而可達成小形輕量化。此組件化開閉 器部，是相分離構造，與框體1的前面垂直地並設，進一 步’在相之間配置遮蔽層，抑制相之間的短路事故的發生 。前述塑模的外表面，是藉由塗抹導電塗料接地，來確保 接觸的安全性。 上述真空2切點3位置開啓模閉器1 3，是具備：包含 絕緣筒的真空容器、及各別收納於此真空容器內的2個固 定電極、及那些的可動電極，構成2切點。在此例中’固 -11 - 200839825 定電極是位於上側，離合於此固定接點的可動電極是 下側。 開閉器1 3的一方的固定電極，是通過可導入母 劃部1 a內的連接套筒1 5與可離合於母線區劃部1 a 母線6連接。且，開閉器1 3的一方的固定電極，是 可導入纜線區劃部1 c內的連接套筒1 6與可離合於纜 劃部1 c內的纜線的T型拉索接頭連接。 / 在接近開閉器1 3的框體1的前側，是配置有驅 向爲上下方向（第7圖的上下方向）也就是開閉器用的 鐵驅動部1 7及接地開閉器用的電磁鐵驅動部1 7。 這些電磁鐵驅動部1 7、1 8，是分別通過操作機 、20與開閉器13及接地開閉器14連結。電磁鐵驅 1 7、1 8、操作機構部1 9、20是構成操作器。 上述開閉器1 3、接地開閉器1 4、電磁鐵驅動部 1 8及操作機構部1 9、20等的機器，是如第5圖及第 ί 所示，收納配置於由：底構件2 1、及各別設在此底 2 1的左右側部的側構件22、22、及連結這些的側構^ 、22的複數連結構件23、及設置於側構件22、22的 背面側且可裝卸地固定於纜線區劃部1 c的左右的各個 的固定構件24所組成的框體內。 開閉器1 3、接地開閉器1 4、電磁鐵驅動部1 7、 操作機構部1 9、2 0等機器的朝前述框體內的配置， 後的框體的重心，是考慮成爲框體的左右前後方向的 心部。此框體的重心設定，是爲了極力避免組件化的 位於 線區 內的 通過 線區 動方 電磁 I 19 動部 17、 6圖 構件 牛22 上咅Β "反4 18及 配置 各中 開閉 -12- 200839825 器區劃部1 b朝框體1外搬出及朝框體1內搬入時的倒下 〇 構成上述的開閉器區劃部1 b的框體的側構件22、22 ，是由對應於開閉器1 3及接地開閉器1 4的側部的第1側 部2 2a、及對應於電磁鐵驅動部1 7、1 8的第2側部22b所 構成。第2側部22b，是如對應於低電壓控制區劃部1 d的 側部的第1中間側板9，從第1側部22a延伸直到框體1 f 的正面側爲止。在此第2側部22b的外面側是藉由螺絲可 裝卸地被固定有如第3圖所示的第1中間側板9。此第1 中間側板9，是在開閉器區劃部1 b從框體1搬出之後，從 構成開閉器區劃部1 b的框體的側構件22、22取下，在框 體1的上部側板7及第2中間側板1 0之間，再度組裝。 第1側部22a的背面側端部及固定構件24，是藉由螺絲， 可裝卸地固定於纜線區劃部1 c的左右的各側板4。 在第5圖及第6圖中，顯示從構成開閉器區劃部1 b ( 的框體的側構件22、22中的第2側部22b，取下成爲低電 壓控制區劃部1 d的側板的第1中間側板9的狀態。 回到第3圖，在框體1的底板2的正面部雖設置可裝 卸的板材24，但是此板材24，是使將開閉器區劃部1 b搬 出入用的搬出裝置（後述）中的行走部，爲了不會成爲朝框 體1的進入/退出時的障礙，而如前述可裝卸地設置於框 體1的底板2的正面部。且，在框體1的底板2的正面側 內部，可裝卸地設置暫時支撐開閉器區劃部1 b用的支撐 構件25。此支撐構件25，當將開閉器區劃部1 b搬出入時 -13- 200839825 ，因爲此開閉器區劃部1 b的連接套筒1 5及母線區劃部i a 內的母線6離合，所以開閉器區劃部1 b在框體1內雖會 上下動作’但是這時底面會抵接在開閉器區劃部1 b的底 構件2 1，防止開閉器區劃部1 b的倒下。 接著’使用第8圖乃至第1 3圖說明從上述本發明的 真空絕緣開關裝置的一實施例的框體1的搬出動作。 開閉器區劃部1 b的機器的一部分萬一故障時在現場 f 進行故障部的除去或交換作業的情況，首先，打開上側背 面門1 f、下側背面門1 g，切離纜線區劃部丨c內的纜線及 母線區劃部1 a的連接套筒1 6的連接。 接著，打開正面門1 e，取下開閉器區劃部1 b的電磁 鐵驅動部1 7、1 8、及低電壓控制區劃部1 d的機器的配線 〇 接著，如第8圖所示，解除正面門1 e的第1鉸鏈1 1 的朝第1中間側板9的固定後，將正面門1 e的第2鉸鏈 1 1 2朝框體1的前方向移動，並且更打開正面門1 e，確保 開閉器區劃部1 b的朝框體1前方拉出用的開口空間。 接著，取下螺絲並解除低電壓控制區劃部1 d的成爲 側板的上部側板7的下部及第1中間側板9的上部的結合 ，取下螺絲並解除低電壓控制區劃部1 d的成爲側板的第1 中間側板9的下部及第2中間側板1 0的上部的結合’且 ，取下螺絲並解除第2中間側板1 0的下部及下部側板8 的上部的結合。 接著，將第3圖所示的設在框體1的底板2的正面部 -14- 200839825 的板材24，從框體1的底板2取下，確保移動形的搬運裝 置（昇降機）A的朝框體1內的進入口。搬運裝置A，是在 此例中由：行走體A1、及固定於此行走體A1上的導引框 A2、及沿著此導引框A2昇降的叉狀的支撐腕A3、及操作 桿A4所構成（第1 1圖〜第13圖參照）。 接著，如第1 1圖所示，將搬運裝置A移動於框體1 內，使其支撐腕A3位於開閉器區劃部1 b的下方側後，上 昇調整使支撐腕A3的支撐高度抵接於閉器區劃部1 b的下 面。 接著，取下螺絲並解除開閉器區劃部1 b的第1側部 2 2a的背面側端部及固定構件24、及將與纜線區劃部1 c 的左右的各側板4的結合後，將低電壓控制區劃部1 d的 成爲側板的第2中間側板1 〇，從第1中間側板9及下部側 板8之間拔取。藉由這些的作業，開閉器區劃部1 b，是從 框體1分離，成爲載置於搬運裝置A的支撐腕A3上的狀 態。 接著，藉由搬運裝置A的支撐腕A3，下降開閉器區 劃部1 b，如第1 2圖所示，切離開閉器1 3中的一方的固定 電極側的連接套筒1 5及母線區劃部1 a內的母線6的電連 接。 接著，藉由將搬運裝置A如第13圖朝後方側（第13 圖右側）移動，就可以將開閉器區劃部1 b從框體1折除並 搬出。 之後，依據需要，將第1中間側板9及第2中間側板 -15- 200839825 1 〇，再度組裝於上部側板7及下部側板8之間。 將零件已修理完成的開閉器區劃部1 b組裝於框體1 的情況時，進行與上述作業程序相反的作業即可。 在上述本發明的一實施例中，被收納於框體1內的機 器中最重的開閉器1 3及其操作機構部1 9、2 0，因爲如第 1圖、第3圖所示配置於框體1的高度方向的中間部至下 方的空間內，所以可降低開關裝置整體的重心。其結果， 開關裝置的搬運，安裝作業的安全性提高。且，也可抑制 設置後的因地震的倒下，可以確保其安全性。 且，在本發明的一實施例中，因爲使可動電極對於固 定電極位於下方的方式將開閉器1 3配置於框體1內，並 且在框體1內供操作可動電極的操作裝置也一倂配置於其 高度方向的下方側，任何原因的操作裝置故障、破損情況 ，開閉器的可動接點會藉由自重從固定接點遠離地朝下方 移動。由此，可發揮安全裝置功能，可以提高安全性。 進一步，在本發明的一實施例中，除了上述結構以外 ，母線6因爲配置於開閉器1 3的上方，所以操作裝置不 會位於於母線連接部附近。由此，可以提高母線連接作業 時的安全性。 且，在本發明的一實施例中，朝母線連接部的母線6 的連接作業，雖是將母線6從框體1的側方導入框體1內 ，藉由將母線6從母線連接部的上方母線朝向連接部下降 而連接於母線連接部，但是如第1圖所示，母線6及其連 接部，是藉由配置於開閉器1 3的上方且位置於作業者的 -16- 200839825 胸前的高度，並藉由打開正面門1 e使正面門1 e 低電壓控制部1 d —起朝框體1外移動，就可確 線連接作業用的作業空間，並且可以在作業者無 姿勢的穩定狀態下，進行母線連接部的連接作業 進一步，上述母線的連接作業，雖是在列盤 要畫數的開關裝置後實施，但是在開關裝置內， 裝了出貨試驗完成的內藏機器的狀態下，可以進 連接作業，所以可以提高信賴性。 進一步，藉由組件化被設在前述正面門1 e 低電壓控制部1 d，並將此低電壓控制部1 d可裝 於正面門1 e的背面，在維修檢點時就可容易實 控制部1 d單體的動作試驗，且，也容易進行被 電壓控制部1 d內的保護繼電器等的交換作業。 且’依據本發明的一實施例，藉由將開閉器 開閉器用的操作器作成1個開閉器組件（開閉器 ，就可一倂折除、交換開閉器組件，其作業性提 達成作業時間的短縮。 且’開閉器及操作此開閉器用的操作器，因 相互影響，所以即使假設開閉器三相內的一相故 ，雖只交換一相的開閉器，但就需要進行操作器 。因此，在現場可以從開關裝置盤交換每一相真 構造的情況時，交換後在開關裝置盤內有需要重 操作器的調整，因爲需要在盤內的限定空間進行 以作業性差，也不易確認，但是本發明，因爲是 的背面的 保上述母 不自然的 〇 配置了需 因爲在實 行母線的 的背面的 卸地安裝 施低電壓 收納於低 及操作此 [劃部lb) 高，可以 爲作動上 障的情況 的再調整 空開關的 新進行與 作業，所 在開閉器 -17- 200839825 及其操作器組件化的狀態下，可以一倂折除、交換的構造 ，所以從盤外折除之後，可以在確保充分的作業空間的狀， 態下作業，可提高作業性，因爲與作業後的確認作業也容 易，所以可以提供信賴性高的開閉器組件。 進一步，在本發明的實施例中，作爲成爲開閉器區劃 部1 b的開閉器組件的予備品，是準備已經完成開閉器及 其操作器的調整的組件的話，即使萬一產生需要交換的情 況，也可立即將開閉器組件交換爲予備品，故障後的復舊 作業時間可抑制在最小限度。 且，在本發明的實施例中，前述開閉器組件是在盤內 朝上下方向昇降可能的構造，不需移動被配置於開閉器組 件的上部的固體絕緣母線的位置，就可以裝卸開閉器組件 。開閉器組件因爲是位於相隣盤及該盤之間的部位，所以 例如交換作業時，移動到固體絕緣母線的位置的話，因爲 需要進行相隣的盤的母線連接部的作業’導致作業量及作 業時間的增加。 且，即使對於已確認健全性的相鄰的盤，只要將母線 連接部取下交換後，將母線再連接的話’之後’因爲需要 重新進行健全性的確認試驗’檢查時間也增加’但是依據 本發明的實施例，開閉器組件部因爲是可以朝上下方向昇 降的構造，所以只要移動固體絕緣母線的位置即可，作業 因爲只要交換該盤即可，所以可以達成作業時間的大幅的 短縮。 進一步，在本發明的實施例中’因爲將開閉器組件的 -18- 200839825 框體，作爲構成開關裝置盤的框架的一部分共用，當然可 達成零件數的降低，原本的話，需要開關裝置盤內確保供 取下開閉器組件用的空間，但藉由取下開閉器組件，開關 裝置整體的尺寸雖變大，但是構成開關裝置的框架的一部 分是藉由共用化，開關裝置盤內就不需要確保供取下開閉 器組件用的空間，開關裝置整體的尺寸可小形化。 且，在本發明的實施例中，對應於開閉器組件的下方 側部，藉由設置對於框體可裝卸的第2中間側板，當折除 、交換開閉器組件時，藉由從框體取下前述第2中間側板 ，就可以確保供開閉器組件昇降用的空間。因此，即使共 用構成開閉器組件的開關裝置盤的框架的一部分的狀態， 開閉器組件的昇降動作也可能。 進一步，在本發明的實施例中，是藉由在開閉器組件 的下面側的框體內，設置開閉器組件的昇降時支撐開閉器 組件用的支撐構件，就可以容易實施搬運裝置的從盤內的 開閉器組件的折除、交換作業。且，支撐開閉器組件下部 的本方式的情況，在母線的開閉器組件上部，因爲不需要 任何作業空間，所以不會影響被收納於盤內的其他的機器 ，可實施該開閉器組件的折除、交換作業。 且，在本發明的實施例中，因爲是在框體1的底板2 的正面門1 e側的一部分，可裝卸板材，所以開閉器組件 的折除、交換時藉由取下該板材，就沒有妨礙搬運裝置的 進入的部位，在開閉器組件的朝框體（盤）的折除及交換作 業，可以容易將搬運裝置朝盤內外移動。 -19- 200839825 進一步，在本發明的實施例中，對於供開關裝置的正 面門1 e開閉用的複數門開閉用鉸鏈，如只容許旋轉動作 的第1鉸鏈1 1、及容許旋轉動作及前後左右動作的第2鉸 鏈1 2，因爲各使用1個以上，所以在通常運轉時，因爲只 容許旋轉動作的第1鉸鏈1 1存在，所以正面門1 e不會朝 前後左右方向移動，可以由與一般的配電盤同樣的門的開 閉動作（旋轉動作）所運用。另一方面，在開閉器組件部的 折除、交換作業時，藉由取下只容許旋轉動作的第1鉸鏈 1 1，藉由第2鉸鏈1 2就可將正面門1 e也朝前後左右方向 動作，當將開閉器組件朝盤內外搬出、搬入時，藉由將正 面門1 e朝前後左右方向動作，就可以確保開閉器組件的 搬出、搬入空間。 且，在本發明的實施例中，將開關裝置的正面門1 e 朝前後左右方向移動時，藉由在正面門1e及底板2之間 ，設置供支撐正面門le的自重用用的支撐金屬件，可降 低施加於鉸鏈的負荷，即使使用小形的鉸鏈’也可維持強 度。 又，在上述的實施例中’爲了確保移動形的搬運裝置 (昇降機）A的朝框體1內的進入口，如第3圖所示雖在框 體1的底板2的正面部，設置可裝卸的板材2 4 ’但是搬運 裝置（昇降機）A的結構’特別是其支撐腕是插入於框體1 內的結構的情況時，不需要設置可裝卸的板材2 4。 且，在上述的實施例中’是設置於框體1的底板2的 正面側內部將開閉器區劃部1 b暫時支撑的支撐構件2 5 ’ -20- 200839825 是常設在框體1的底板2的正面側內部也可以，作業時附 設也可以。 進一步，在上述的實施例中，開閉器區劃部1 b內的 開閉器，雖例示真空2切點3位置開啓模閉器（真空2切 點3位置型遮斷斷路器），但是開閉器區劃部1
