Maintenance-free medium and high pressure fully prefabricated polyester film mechanical wrapping tubular busbar

遼寧博際電氣技術有限公司中高壓全預制聚脂薄膜機械繞包式管型母線是在中國電力科學研究院高壓干式穿墻套管和高壓干式電流互感器電容型絕緣包制技術基礎上，實現十個創新飛躍的產品。

Liaoning Boji Electric Technology Co., Ltd. medium and high voltage fully prefabricated polyester film mechanical wrapping tubular bus is a product that has achieved ten innovative leaps on the basis of the capacitive insulation packaging technology of high-voltage dry wall sleeve and high-voltage dry-type current transformer of China Electric Power Research Institute.

一是由單根單獨的管型母線電場均化理論向管型母線與全預制式電容型屏蔽筒相配合的電場均化理論飛躍，形成了全預制電容型絕緣管型母線的電場均化理論。

The first is the leap from the electric field equalization theory of a single tubular bus to the electric field equalization theory of the combination of tubular bus and fully prefabricated capacitive shielding cylinder, and the electric field equalization theory of fully prefabricated capacitive insulated tubular bus is formed.

 二是由手工包制向機械包制飛躍，使管型母線局部放電性能滿足行業標準。

The second is to make a leap from manual packaging to mechanical packaging, so that the partial discharge performance of tubular bus bar meets industry standards.

 三是由聚四氟乙烯帶包制向用聚脂薄膜包制飛躍，使管型母線局部放電性能更好，成本更低、性價比更高。

The third is to make a leap from PTFE tape to polyester film, so that the tubular bus has better partial discharge performance, lower cost and higher cost performance.

 四是由單根6米短距離直線包制向單根18米長距離直線包制飛躍，大幅度地減少了中間接頭的使用數量，安全性更高。

Fourth, it is a leap from a single 6-meter short-distance linear package to a single 18-meter long-distance linear package, which greatly reduces the number of intermediate joints and has higher safety.

 五是由一種角度彎管機械包制向多種角度彎管機械自動跟隨包制飛躍，使彎管型母線局放性能進一步提高。

Fifth, it is a leap from one angle bending machinery to a variety of angle bending machinery automatically following the package system, so that the partial discharge performance of the bent bus bar is further improved.

 六是管型母線接頭處的絕緣由現場包制向工廠預制飛躍，使管型母線局部放電性能徹底受控。

Sixth, the insulation at the tubular bus joint is made from on-site packaging to factory prefabrication, so that the partial discharge performance of the tubular bus is completely controlled.

 七是由固定式全預制電容型屏蔽筒向伸縮式全預制電容型屏蔽筒飛躍，解決了管型母線在全屏蔽情況下熱脹冷縮問題，并能保證局放、耐壓、雷電沖擊各項電氣性能穩定。

Seventh, it is a leap from the fixed fully prefabricated capacitive shielding tube to the telescopic fully prefabricated capacitive shielding tube, which solves the problem of thermal expansion and cold contraction of the tubular bus in the case of full shielding, and can ensure the stability of the electrical properties of partial discharge, voltage resistance and lightning impact.

 八是管型母線局部放電性能由工廠檢測向在線監測飛躍，從而確保管型母線長期安全運行。

Eighth, the partial discharge performance of the tubular bus has leaped from factory testing to online monitoring, so as to ensure the long-term safe operation of the tubular bus.

 九是導體連接由機械連接向焊接飛躍，使導體連接實現免維護。

The ninth is that the conductor connection leaps from mechanical connection to welding, so that the conductor connection is maintenance-free.

 十是由中壓管型母線向高壓管型母線飛躍，使管型母線有了更廣闊的發展空間。

Tenth, it is a leap from medium pressure tubular bus to high pressure tubular bus, so that the tubular bus has a broader development space.
