封閉式母線槽橋架的隔離措施
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(jì)南電纜橋架按照母線槽排列圖，將各節(jié)母線槽，插接開(kāi)關(guān)箱，進(jìn)線箱運(yùn)各安裝地點(diǎn)。安裝前應(yīng)逐節(jié)搖測(cè)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(shè)距地高度不應(yīng)小于2.2m。各段母線槽槽的外殼連接應(yīng)是可拆的，外殼間有跨接地線。兩端應(yīng)可靠接地。母線槽槽的端頭應(yīng)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(yīng)做固定支架，過(guò)樓板處應(yīng)加裝防震裝置，并做防水臺(tái)，防水臺(tái)應(yīng)在土建澆灌混凝土?xí)r一次作成，高度50mm寬度80mm，混凝土強(qiáng)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(yīng)用與側(cè)臥安裝的轉(zhuǎn)彎，也應(yīng)用于垂直安裝與平臥安裝之間的過(guò)度，T型垂直彎頭應(yīng)用與側(cè)臥安裝的轉(zhuǎn)彎，也應(yīng)用與垂直安裝與平臥安裝之間的過(guò)度，Z型水平彎頭應(yīng)用于母線槽平臥的轉(zhuǎn)彎，Z型垂直彎頭應(yīng)用于母線槽側(cè)臥安裝的轉(zhuǎn)彎，變壓器母線槽槽應(yīng)用于大容量母線槽槽向小容量母線槽槽的過(guò)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(yīng)采用保護(hù)措施(電氣專用豎井，配電室，電機(jī)室，設(shè)備層等除外)。封閉式母線槽穿越防火墻，防火樓板時(shí)，應(yīng)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(shí)將母線槽的小頭插入另一節(jié)母線槽的大頭中去，在母線槽間及母線槽外側(cè)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.
