高強(qiáng)度封閉母線槽其工藝制造不受板材限制，濟(jì)南電纜橋架外殼做成瓦溝形式，使母線機(jī)械強(qiáng)度增加，母線水平段可生產(chǎn)13m長(zhǎng)。由于外殼做成瓦溝形式，坑溝位置有意將母線分隔固定，母線之間有18mm的間距，線間通風(fēng)良好，使母線槽的防潮和散熱功能有明顯的提高，比較適應(yīng)南方氣候。

　　The high strength enclosed bus groove is not limited by sheet metal, and the shell of Ji'nan cable bridge is made of tile groove, which increases the mechanical strength of the bus bar, and the horizontal section of the bus can be produced to 13m length. Because the shell is made of tile groove, the location of pit ditch is fixed by bus bar, the distance between the bus bars is 18mm, the ventilation between the lines is good, so that the function of moisture-proof and heat dissipation of the bus slot is obviously improved, which is more suitable for the southern climate.

　　空氣式插接母線槽由于母線之間接頭用銅片軟接過渡，在南方天氣潮濕，接頭之間容易產(chǎn)生氧化，形成接頭與母線接觸不良，使觸頭容易發(fā)熱，故在南方極少使用。并且接頭之間體積過大，水平母線段尺寸不一致，外形不夠美觀。

　　Because of the soft copper transition between the bus joints, the air type plug in bus bar is easy to be oxidized in the south, and the contact between the joint and the bus is bad, which makes the contact easy to heat, so it is rarely used in the south. And the size between the joints is too large, the size of the horizontal mother line is not consistent, the appearance is not beautiful.

　　密集絕緣插接母線槽其防潮、散熱效果較差。在防潮方面，母線在施工時(shí)，容易受潮及滲水，造成相間絕緣電阻下降。母線的散熱主要靠外殼，由于線與線之間緊湊排列安裝，L2、L3相熱能散發(fā)緩慢，形成母線槽溫升偏高。

　　Dense insulated plug-in busbar has poor moisture-proof and heat dissipation effects. In the aspect of moisture proof, the busbar is easy to damp and seep during construction, resulting in the decrease of interphase insulation resistance. The heat dissipation of the bus is mainly due to the shell, because of the compact arrangement between the line and the line, the heat dissipation of L2 and L3 phase is slow, and the temperature rise of the busbar is higher.

　　密集絕緣插接母線槽受外殼板材限制，只能生產(chǎn)不大于3m的水平段。由于母線相間氣隙小，母線通過大電流時(shí)，產(chǎn)生強(qiáng)大的電動(dòng)力，使磁振蕩頻率形成疊加狀態(tài)，造成過大的噪聲。

　　Dense insulated plug-in busbar is limited by shell plate and can only produce horizontal section less than 3m. Because of the small air gap between the bus bars, the bus generates strong electric force when passing through the large current, which makes the magnetic oscillation frequency superposition, causing excessive noise.

　　插接式母線槽屬樹干式系統(tǒng)，具有體積小、結(jié)構(gòu)緊湊、運(yùn)行可靠、傳輸電流大、便于分接饋電、維護(hù)方便、能耗小、動(dòng)熱穩(wěn)定性好等優(yōu)點(diǎn)，在高層建筑中得到廣泛應(yīng)用。

　　Plug type busbar is a trunk type system, which has the advantages of small size, compact structure, reliable operation, high transmission current, easy to tap and feed, convenient maintenance, small energy consumption, good dynamic thermal stability and so on. It has been widely used in high-rise buildings.
