摘要

特高压并联电抗器噪声问题日益突出

加装隔声装置能有效降低特高压并联电抗器噪声;但隔声装置可能造成特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

因此需对加装隔声装置后的特高压并联电抗器散热性能进行分析。通过有限元方法建立特高压并联电抗器模型

模拟其产热与散热过程

研究加装隔声装置前后的特高压并联电抗器散热性能

分析了油箱内温度分布情况以及温升值。研究表明

安装该隔声装置会导致特高压并联电抗器内部温升值增大2

但不会影响其安全稳定运行;仿真结果与试验结果有很好的一致性。电抗器内部热量散出主要依赖绝缘油的循环流动;在电抗器散热性能良好的前提下

安装隔声装置不会对其温升有较大影响。

Abstract

The noise of an ultra-high voltage shunt reactor is becoming more and more prominent.In order to reduce the noise of the reactor

a sound insulation device is applied to get large noise reduction.But it may cause reactor heat problem and its internal temperature rise.High temperature will degrade the insulation system performance

and have an impact on the operation reliability and economic performance of the reactor.It is necessary to study the heat dissipation of shunt reactor with sound insulation device.Consequently

using the finite element method

we established a model of UHV shunt reactor to simulate the process of heat production and heat dissipation.Moreover

we studied the heat dissipation performance

the temperature distribution

and the temperature rise before and after the installation of sound insula

tion device.The simulation results are in good agreement with the experimental ones

the internal temperature of the reactor is increased only 2

K after installation of sound insulation device

but it will not affect its stable operation.The heat dissipation of the reactor is mainly determined by the circulating flow of the insulating oil.Under the premise of good heat dissipation performance of the reactor

the installation of the sound insulation device will not significantly affect the temperature rise.
