一种能量回馈型电池核容装置

直流电源系统是发电厂、变电站站用电源系统的重要组成部分,相当于发电厂、变电站的"心脏",保障了发电厂、变电站信号、控制、继电保护和事故照明等操作电源的供应。作为直流系统后备电源的蓄电池又是直流电源的最核心部件之一,是保障直流系统可靠性的最后一道防线。阀控式铅酸电池占据电厂和变电站直流系统蓄电池的绝对份额,检验蓄电池好坏的最可靠的办法仍然是核容。目前普遍采用电子或电阻发热型核容装置,需要人在现场看守,费时费力。文章提出的能量回馈型核容装置发热少,可以支持远程无人值守的核容方式,大大节省人力。

DC power supply system is an important part of power supply system for power plants and substations, which is equivalent to the "heart" of power plants and substations. It ensures the supply of operating power supply such as power plant, substation signal, control, relay protection and accident lighting. As the backup power supply of DC system, battery is one of the core components of DC power supply, and it is the last line of defense to ensure the reliability of DC system. Valve-controlled lead-acid batteries account for the absolute share of batteries in DC systems of power plants and substations. The most reliable way to test the quality of batteries is still nuclear capacity. At present, it is widely used as an electronic or resistive heating nuclear capacitance device, which needs to be guarded on the spot, so it is time-consuming and laborious. The energy feedback nuclear capacity device proposed in this paper has less heat, can support the remote unattended nuclear capacity mode, and greatly saves manpower.
