密集型母線的“三明治”結(jié)構(gòu)相對空氣型母線“柵格式”結(jié)構(gòu)明顯存在體積小、占用空間小的優(yōu)勢；The "sandwich" structure of the compact busbar has obvious advantages of small volume and less space occupation compared with the "grid-like" structure of the air type busbar.

一般低壓系統(tǒng)輸電線路的電壓降指標(biāo)主要取決于輸電線路的電阻、容抗、感抗，空氣型外殼為磁性材料（鋼），渦流現(xiàn)象明顯，具有較大的容抗和感抗，電壓降明顯，電能損耗較大；而密集型母線緊密的結(jié)構(gòu)，大大降低了母線系統(tǒng)的阻抗，鋁鎂合金外殼更加避免了磁滯渦流現(xiàn)象的產(chǎn)生，使得整個系統(tǒng)電壓降非常小，能耗非常低；發(fā)熱量小、散熱快；The voltage drop index of the general low-voltage system transmission lines mainly depends on the resistance, capacitance reactance and inductance reactance of the transmission lines. The air-type enclosure is made of magnetic material (steel), and the eddy current phenomenon is obvious, with large capacitance reactance and inductance reactance, obvious voltage drop and large power loss. However, the compact structure of the compact busbar greatly reduces the impedance of the busbar system. The aluminum-magnesium alloy enclosure further avoids the occurrence of magnetic hysteresis and eddy current phenomenon, resulting in a very small voltage drop of the entire system and very low energy consumption. It generates less heat and dissipates heat quickly.

密集型母線擁有空氣型母線難以比擬的低阻抗特點，在發(fā)熱指標(biāo)上密集型母線更小；母線系統(tǒng)是全封閉結(jié)構(gòu)，防護等級最高可達到IP68,所以密集型母線熱傳遞方式為“熱傳導(dǎo)”，能很快通過銅母排和鋁鎂合金外殼把熱量散發(fā)，大大提升銅排的導(dǎo)電效能，優(yōu)化了銅排的載流截面；空氣型母線傳遞方式為“輻射”，而金屬間的熱“傳導(dǎo)”勢必優(yōu)越于氣體介質(zhì)的熱“輻射”，而且空氣型母線槽外殼大多數(shù)采用鋼制外殼故而散熱效果不佳，為了保證母線槽的載流需要必須加大銅排截面，增加了成本，所以相對而言空氣型母線槽的性價比不高，漸漸被市場淘汰更新。The compact busbar has an extremely low impedance feature that is unmatched by the air type busbar, and the heat generation index of the compact busbar is smaller. The busbar system is a fully enclosed structure, and the maximum protection level can reach IP68. Therefore, the heat transfer method of the compact busbar is "thermal conduction", which can quickly dissipate heat through the copper busbar and the aluminum-magnesium alloy enclosure, greatly enhancing the conductive efficiency of the copper bar and optimizing the current-carrying section of the copper bar. The heat transfer method of the air type busbar is "radiation", and the thermal "conduction" between metals is bound to be superior to the thermal "radiation" of the gas medium. Moreover, the majority of the shells of air type busbar channels adopt steel enclosures, resulting in poor heat dissipation effect. In order to ensure the current-carrying capacity of the busbar channel, it is necessary to increase the section of the copper bar, increasing the cost. Therefore, relatively speaking, the cost performance of the air type busbar channel is not high and it is gradually eliminated and updated by the market.空氣型母線外殼組裝基本采用螺栓連接，密集型母線采用全自動鉚接系統(tǒng)組裝，前者在電氣運行（伴隨震動）過程中極容易發(fā)生螺栓松動、脫落，存在安全隱患，而后者摒棄了傳統(tǒng)的螺栓連接，電氣連續(xù)性好，同時避免了人為因素，裝配精度高。The assembly of the enclosure of the air type busbar is basically by bolt connection, while the compact busbar is assembled by a fully automatic riveting system. In the former case, during the electrical operation (accompanied by vibration), bolt loosening and shedding are extremely likely to occur, posing a potential safety hazard. In contrast, the latter discards the traditional bolt connection, has good electrical continuity, and avoids human factors at the same time, with high assembly accuracy.

 空氣型母線有著它難以避免的“煙囪效應(yīng)”，一旦一處著火，其中空式的結(jié)構(gòu)正好充當(dāng)煙囪的角色，使得整個火勢蔓延速度加快，存在嚴重的安全隱患。The air type busbar has an inevitable "chimney effect". Once there is a fire at one point, its hollow structure acts exactly like a chimney, accelerating the spread of the fire, presenting a serious safety hazard.

1、空氣型母線對環(huán)境的要求不太苛刻，能滿足相對濕度較大的空間、高層建筑等等，在產(chǎn)品的耐用性上有非常明顯的優(yōu)勢；1. The air type busbar has less strict requirements on the environment and can meet the needs of spaces with relatively high humidity, high-rise buildings, etc. It has a very obvious advantage in terms of product durability.

2、空氣型母線維護方便，空氣型的采用絕緣隔塊加螺栓固定的方式，緊急情況可以在現(xiàn)場拆開更換絕緣件和導(dǎo)體。2. The air type busbar is convenient for maintenance. The air type adopts the method of insulation spacer plus bolt fixation, and in an emergency, the insulation components and conductors can be disassembled and replaced on site.

3、空氣型母線槽絕緣是使用絕緣隔塊加螺栓固定的方式，所以絕緣效果也比密集型母線槽有很大的優(yōu)勢。3. The insulation of the air type busbar channel is in the form of insulation spacers plus bolt fixation, so the insulation effect also has a great advantage over the compact busbar channel.
