封閉式母線槽橋架的隔離措施

  1、按母線槽排列圖,從起始端(或電氣豎井入口處)開始向上,向前安裝。曲線母線槽槽在插接母線槽組裝中要根據其部位進行選擇,L型水平彎頭應用于平臥水平安裝的轉彎,也應用于垂直安裝與側臥水平安裝的過度。

  1, according to the bus slot diagram, starting from the end (or the entrance of the electrical shaft) upward, forward installation. The curve bus groove is selected according to its position in the assembly of the plug-in busbar, and the L horizontal bend is applied to the flat horizontal installation turn. It is also applied to the vertical installation and lateral horizontal installation.

  2、濟南電纜橋架按照母線槽排列圖,將各節母線槽,插接開關箱,進線箱運各安裝地點。安裝前應逐節搖測母線槽的絕緣電阻,電阻值不得小于20MΩ。母線槽槽,固定距離不得大于2.5m,水平敷設距地高度不應小于2.2m。各段母線槽槽的外殼連接應是可拆的,外殼間有跨接地線。兩端應可靠接地。母線槽槽的端頭應裝封閉罩。

  2, according to the bus slot arrangement diagram, each bus slot, plug switch box, into the line box shipped to the installation site. Before installation, the insulation resistance of the bus slot shall be measured by pitch, and the resistance value shall not be less than 20M. The fixed distance of the bus groove shall not be greater than 2.5m, and the horizontal laying distance shall not be less than 2.2m. The housings of each busbar slot shall be removable and there is a jumper wire between the housings. Both ends shall be grounded reliably. The end of the bus groove shall be equipped with a closed cover.

  3、封閉式母線槽垂直安裝,沿墻或柱子處,應做固定支架,過樓板處應加裝防震裝置,并做防水臺,防水臺應在土建澆灌混凝土時一次作成,高度50mm寬度80mm,混凝土強度不少于C20。

  3, closed busbar vertical installation, along the walls or columns, should do the fixed bracket, the roof should be installed over the shock protection device, and waterproof, waterproof should be a civil in the pouring of concrete into, height 50mm width 80mm, concrete strength is not less than C20.

  4、L型彎頭應用與側臥安裝的轉彎,也應用于垂直安裝與平臥安裝之間的過度,T型垂直彎頭應用與側臥安裝的轉彎,也應用與垂直安裝與平臥安裝之間的過度,Z型水平彎頭應用于母線槽平臥的轉彎,Z型垂直彎頭應用于母線槽側臥安裝的轉彎,變壓器母線槽槽應用于大容量母線槽槽向小容量母線槽槽的過度。

  4, L application and installation of lateral elbow turn, also applies to the installation of vertical and horizontal installation between excessive turning T vertical elbow application and laterally arranged, but also between the application and the installation of vertical and horizontal installation over Z type horizontal elbow used in busbar recumbent turn, Z vertical elbow application in the busbar installation side turn, transformer bus slot used in large capacity bus slot to small capacity bus slot over.

  5、封閉式母線槽垂直安裝距地1.8m以下應采用保護措施(電氣專用豎井,配電室,電機室,設備層等除外)。封閉式母線槽穿越防火墻,防火樓板時,應采取防火隔離措施。

  5. The enclosed bus groove shall be installed vertically. The protection measures should be adopted below the ground 1.8m, except for the electric shaft, the power distribution room, the motor room, the equipment layer and so on. Closed type bus trough through the firewall, fire floor, fire isolation measures should be taken.

  連接時將母線槽的小頭插入另一節母線槽的大頭中去,在母線槽間及母線槽外側墊上配套的絕緣板,再穿上絕緣螺栓加平墊片,彈簧墊圈,然后擰上螺母。

  Connect the busbar and busbar section head insert another head to insulation board supporting in busbar and busbar lateral pad, and then put on the insulation of bolts and flat washers, spring washers, and screw nut.
