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

辽宁博际电气技术有限公司中高压全预制聚脂薄膜机械绕包式管型母线是在中国电力科学研究院高压干式穿墙套管和高压干式电流互感器电容型绝缘包制技术基础上，实现十个创新飞跃的产品。

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.

一是由单根单独的管型母线电场均化理论向管型母线与全预制式电容型屏蔽筒相配合的电场均化理论飞跃，形成了全预制电容型绝缘管型母线的电场均化理论。

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.

 二是由手工包制向机械包制飞跃，使管型母线局部放电性能满足行业标准。

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.

 三是由聚四氟乙烯带包制向用聚脂薄膜包制飞跃，使管型母线局部放电性能更好，成本更低、性价比更高。

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.

 四是由单根6米短距离直线包制向单根18米长距离直线包制飞跃，大幅度地减少了中间接头的使用数量，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.

 五是由一种角度弯管机械包制向多种角度弯管机械自动跟随包制飞跃，使弯管型母线局放性能进一步提高。

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.

 六是管型母线接头处的绝缘由现场包制向工厂预制飞跃，使管型母线局部放电性能彻底受控。

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.

 七是由固定式全预制电容型屏蔽筒向伸缩式全预制电容型屏蔽筒飞跃，解决了管型母线在全屏蔽情况下热胀冷缩问题，并能保证局放、耐压、雷电冲击各项电气性能稳定。

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.

 八是管型母线局部放电性能由工厂检测向在线监测飞跃，从而确保管型母线长期安全运行。

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.

 九是导体连接由机械连接向焊接飞跃，使导体连接实现免维护。

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

 十是由中压管型母线向高压管型母线飞跃，使管型母线有了更广阔的发展空间。

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.
