要定期擦拭绝缘子

网址:www。dianLiwuzi。com。cn  2019-07-20  作者:admin    阅读:

对于普通人来说,可能不太明白什么是绝缘子、以及为什么要擦拭绝缘子。据了解,绝缘子是安装在不同电位的导体之间或导体与地电位构件之间的器件,能够耐受电压和机械应力作用,在高铁架空输电线路中起到重要作用。
For ordinary people, it may not be clear what insulators are and why they should be wiped. It is known that insulators are devices installed between conductors with different potentials or between conductors and potential components. They can withstand voltage and mechanical stress and play an important role in overhead transmission lines of high-speed railway.
而之所以要定期擦拭绝缘子,是因为高铁运行时,空气中的灰尘会落在绝缘子上,而且越积越多,如果不及时清除,会造成跳闸或线路短路,影响列车供电、损害列车元器件,进而威胁列车运行安全。可以说,没有绝缘子保障供电,就没有高铁的安全运行。
The reason why insulators should be wiped regularly is that when the high-speed railway is running, the dust in the air will fall on the insulators, and the more accumulated, if not removed in time, it will cause tripping or short circuit of the line, affect the power supply of the train, damage the components of the train, and then threaten the safety of the train operation. It can be said that without insulators to ensure power supply, there will be no safe operation of high-speed rail.
