免维护玻璃钢绝缘低压交直流母线槽

Maintenance-free FRP insulated low-voltage AC/DC bus duct

辽宁博际电气技术有限公司研制的免维护玻璃钢绝缘低压交直流母线槽，是在目前已有的空气母线槽、密集母线槽、环氧浇注母线槽基础上实现五个创新飞跃的产品。

The maintenance-free FRP insulated low-voltage AC/DC bus duct developed by Liaoning Boji Electric Technology Co., Ltd. is a product that has achieved five innovative leaps on the basis of the existing air bus duct, dense bus duct and epoxy cast bus duct.

一是导体由铜排向波纹形薄铜板飞跃，使产品集肤效应低、散热面大，可充分提高导体载流能力，具有成本方面的优势。

First, the conductor leaps from the copper bar to the corrugated thin copper plate, so that the product has a low skin effect and a large heat dissipation surface, which can fully improve the current carrying capacity of the conductor and has the advantage of cost.

二是导体连接方式由螺栓机械连接向焊接飞跃，焊接与传统的螺栓机械连接相比，不仅减小了母线连接处的接触电阻，同时还解决了用螺栓连接易产生松动，需要定期停电紧固螺栓的问题，具有维护方面的优势。

The second is that the conductor connection mode leaps from bolt mechanical connection to welding, welding compared with the traditional bolt mechanical connection, not only reduces the contact resistance of the bus connection, but also solves the problem that the bolt connection is easy to loosen, and the bolt needs to be tightened by regular power failure, which has the advantage of maintenance.

三是外部壳体由金属壳体向扁管形玻璃钢壳飞跃，玻璃钢与传统的金属外壳相比不但具有优秀的绝缘性能和机械性能，而且化学性能稳定、耐腐蚀，密封后防护等级可以满足IP68要求，可在浸水、直埋地下等条件下使用，具有使用范围广阔方面的优势。

Third, the external shell from the metal shell to the flat tubular FRP shell leap, FRP compared with the traditional metal shell not only has excellent insulation and mechanical properties, but also stable chemical properties, corrosion resistance, sealed protection level can meet the requirements of IP68, can be used in water, buried underground and other conditions, with a wide range of advantages in terms of use.

四是导体连接由硬连接改为软连接，使母线导体由刚性热胀冷缩向柔性热胀冷缩飞跃，这样不仅可以使单根母线长度大幅增加，减少母线中间接头数量，同时还具有安装快捷、安装成本低方面的优势。

Fourth, the conductor connection is changed from hard connection to soft connection, so that the bus conductor leaps from rigid thermal expansion and contraction to flexible thermal expansion and contraction, which can not only greatly increase the length of a single bus bar and reduce the number of intermediate joints of the bus, but also has the advantages of fast installation and low installation cost.

五是各相母线由密集布置到空气加绝缘分散布置飞跃，不仅散热好，而且还不会发生相间及相对地短路，具有安全方面的优势。

Fifth, the bus of each phase leaps from dense arrangement to air and insulation scattered arrangement, which not only dissipates heat well, but also does not occur interphase and relative short circuit, which has the advantage of safety.
