超高压电抗器隔声装置降噪散热性能分析

Analysis of noise reduction and heat dissipation performance of sound insulation device of ultra-high parallel voltage reactor

变电站高压并联电抗器噪声问题日渐突出,现有变电站通过对高压并联电抗器加装隔声装置达到控制噪声的目的,但隔声装置可能造成高压并联电抗器散热不足,使内部绝缘系统性能劣化,影响特高压并联电抗器运行可靠性与经济性。本文结合华东某超高压变电站实际应用案例,对加装隔声装置后的高压并联电抗器噪声影响和散热性能进行分析。

Noise problem of high voltage shunt reactor in substation is becoming more and more serious.Noise control is achieved by adding sound insulation device to high voltage shunt reactor in existing substation.However,sound insulation device may cause insufficient heat dissipation of high voltage shunt reactor,deteriorate the performance of internal insulation system,and affect the operation reliability and reliability of UHV shunt reactor.Economy.Based on the practical application of an ultra-high voltage substation in East China,this paper analyses the noise impact and heat dissipation performance of the high voltage shunt reactor with sound insulation device.
