摘要
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 insulation device.The simulation results are in good agreement with the experimental ones,the internal temperature of the reactor is increased only 2～3 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.关键词
