一起电抗器发热问题的分析及对策

Analysis and countermeasure of a heating problem of reactor

为了确定110 kV某变电站3号电容器组串联电抗器发热问题的原因,在现场实地考察以后提出了三点可能原因,通过现场排查,与电能质量测试分析最终确定:电抗器在运行期间,异物堵塞气道,导致电抗器无法正常散热,造成电抗器温升过高。通过此次工程实例,笔者提供了一种对变电站电抗器发热问题的研究与分析的一种合理思路。此外,提出变电站电抗器日常运行时防止出现温升过高的相关建议及对策,确保电抗器安全稳定地运行。

In order to determine the cause of the heating problem of series reactor of No. 3 capacitor group in 1/0 kV substation, the author puts forward three possible reasons after the on-the-spot investigation in the field. field investigation and power quality test and analysis Through the , the author finally determines that at the time of operation, the airway of reactor is blocked by exogenous impurity, resulting in poor heat dissipation, Through the engineering example, the author provides a reasonable way of lem of the reactor in substation. In addition, the author puts forward some the occurrence of temperature rise during the daily operation of substation fion of the reactor. researching and causing the reactor to heat. and analyzing the heating prob- suggestions and countermeasures to prevent reactor to ensure the safe and stable operation of the reactor.
