变电所并联蓄电池及新型充电装置技术探讨

Discussion on Technology of Parallel Battery and New Charging Device in Substation

蓄电池组是变电所交流电源失压后,给二次回路提供供电的可靠电源。如果变电所失去了二次回路电源,变电所就变成了没有保护功能、无法控制的昂贵“输电线路”。本篇文章从变电所串联蓄电池组控制电源的本质隐患入手,较详细论述了并联蓄电池及新型充电装置组成的二次回路可靠性强,举例说明了并联蓄电池技术原理及应用,最后总结了并联蓄电池及新型充电装置推广的原因。

The storage battery is a reliable power supply for the secondary circuit after the voltage loss of the AC power supply in the substation.If the substation loses the secondary circuit power supply,the substation will become an expensive"transmission line"without protection function and control.Starting from the hidden danger of the control power supply of series storage battery in substation,this paper discusses in detail the reliability of the secondary circuit composed of parallel storage battery and new charging device,illustrates the technical principle and application of parallel storage battery,and finally summarizes the reasons for the promotion of parallel storage battery and new charging device.
