母線槽與傳統(tǒng)的電纜相較，在大電流傳輸時充分展現(xiàn)出它的優(yōu)勢，新型技術(shù)和工藝也大幅減小了母線槽兩端部連接處及分線口插接處的接觸電阻和溫升，高品質(zhì)絕緣材料的應用亦提升了母線槽的可靠程度，讓整個系統(tǒng)更為完善。母線槽的特點是具備系列配套、商品化生產(chǎn)、體積小、容量大、設計施工周期短、裝拆便捷、不會燃燒、可靠、使用期限長。母線槽的過載能力較強，這源于它所用的絕緣材料工作溫度較高，母線槽所用的絕緣材料過去采用工作溫度為 105℃的材料，如今已研發(fā)出工作溫度為 140℃以上的輻射交聯(lián)阻燃纏繞帶（PER）和輻射交聯(lián)聚烴熱收縮管。

　　Compared with traditional cables, bus ducts fully demonstrate their advantages in high current transmission. New technologies and processes also significantly reduce the contact resistance and temperature rise at the connection points at both ends of the bus duct and at the junction of the distribution port. The application of high-quality insulation materials also enhances the safety and reliability of the bus duct, making the entire system more complete. The characteristics of busbar trunking are series matching, commercial production, small volume, large capacity, short design and construction period, convenient assembly and disassembly, non combustible, safe and reliable, and long service life. The overload capacity of the bus duct is strong, which is due to the high working temperature of the insulation material used. The insulation material used for the bus duct used to be made of materials with a working temperature of 105 ℃, but now radiation cross-linked flame-retardant winding tape (PER) and radiation cross-linked hydrocarbon heat shrinkable tube with a working temperature of over 140 ℃ have been developed.

　　在檢測絕緣強度時，其中一個檢測探頭固定于片導電片上，另一個檢測探頭從片導電片開始按順序依次挪動到各片導電片上。以此類推，對母線槽內(nèi)部導電片之間的絕緣強度進行兩兩檢測。當挪動到每一片導電片上時，絕緣強度檢測儀會檢測出兩個檢測探頭所檢測的兩片導電片之間的絕緣強度。檢測導電片電阻則比檢測絕緣強度簡便許多，只需控制兩個檢測探頭同時挪動到同一片導電片的兩端，微歐計即可測出該導電片的電阻。測得的導電片電阻和絕緣強度會自動傳輸?shù)缴衔粰C。

　　When detecting insulation strength, one of the detection probes is fixed on the first conductive sheet, and the other detection probe is moved sequentially from the first conductive sheet to each conductive sheet. Similarly, perform pairwise tests on the insulation strength between the conductive sheets inside the bus duct. When moved onto each conductive sheet, the insulation strength detector will detect the insulation strength between the two conductive sheets detected by the two detection probes. Detecting the resistance of a conductive sheet is much simpler than detecting insulation strength. Simply control two detection probes to move to both ends of the same conductive sheet at the same time, and a micro ohmmeter can measure the resistance of the conductive sheet. The measured resistance and insulation strength of the conductive sheet will be automatically transmitted to the upper computer.

　　由于母線槽鋪設環(huán)境及安裝要求較為特殊，在建筑物內(nèi)需單獨預留電氣豎井作為專用空間，對于一幢高層建筑物而言，從上下電氣豎井所占用的面積頗為可觀，增加了土建投資；母線槽是一節(jié)一節(jié)安裝的，每節(jié)將近百公斤，安裝就位全依賴人力搬動及調(diào)整，其勞動強度之大可想而知；因?qū)痈卟煌㈦娏鞯燃壐鳟悾妇€槽的互換能力往往較差，若接頭不平整光滑，擰緊接頭連接螺栓的空間又過小，安裝就更耗費時間與精力；此外母線槽的安裝要求較為嚴格，安裝時需避免產(chǎn)生碰撞、敲擊，連接螺栓的緊固要適度，過緊或過松都會造成隱患。

　　Due to the special environment and installation requirements for busbar trunking, a separate electrical shaft needs to be reserved as a dedicated space in the building. For a high-rise building, the area occupied by the electrical shaft from top to bottom is considerable, which increases the civil engineering investment; The bus duct is installed section by section, with each section weighing nearly 100 kilograms. The installation relies entirely on manual movement and adjustment, and its labor intensity can be imagined; Due to differences in floor height and current levels, the interchangeability of bus ducts is often poor. If the joints are not smooth and the space for tightening the joint connection bolts is too small, installation will be more time-consuming and labor-intensive; In addition, the installation requirements for bus ducts are relatively strict. During installation, collision and knocking should be avoided, and the fastening of connecting bolts should be moderate. Over tightening or over loosening can cause hidden dangers.

　　母線槽制作工藝陳舊，幾乎均為手工制作，人為因素較多，質(zhì)量優(yōu)劣無法有效管控。建設單位在母線槽訂貨時，需對母線槽制造廠家的生產(chǎn)規(guī)模、技術(shù)實力、工人素質(zhì)及生產(chǎn)環(huán)境進行一番深入詳盡的考察，尤其是生產(chǎn)環(huán)境。因為若絕緣處理在不潔凈的空間中進行，絕緣層中難免會存在一些導電微粒，運行初期或許并無影響，但時間一長就會導致絕緣損壞。

　　The production process of bus duct is outdated, almost all of which are handmade, and there are many human factors, making it difficult to effectively control the quality. When ordering bus ducts, the construction unit needs to conduct a thorough and detailed investigation of the production scale, technical strength, worker quality, and production environment of the bus duct manufacturer, especially the production environment. Because if insulation treatment is carried out in an unclean space, there may inevitably be some conductive particles in the insulation layer, which may not have an impact during the initial operation, but over time can lead to insulation damage.

　　母線槽供電干線的連續(xù)性能差、接頭較多；氣密和防水性能差；耐腐蝕性能、抗震性能、供電可靠性差；施工現(xiàn)場環(huán)境要求高和安裝空間尺寸要求高；施工難度大、周期長、使用年限短且維護工作量大等諸多弊端。

　　The continuity performance of the bus duct power supply main line is poor and there are many joints; Poor airtightness and waterproof performance; Poor corrosion resistance, seismic performance, and power supply reliability; High requirements for construction site environment and installation space dimensions; There are many drawbacks such as high construction difficulty, long construction period, short service life, and heavy maintenance workload.
