Abstract
Temperature field distribution of dry-type air-core shunt reactor is of much importance for the equipment safety and reliable operation.In order to improve the calculation precision of the temperature field of dry-type air-core reactor,based on the multi-field coupling finite element theory,an electromagnetic-fluid-temperature multi-field coupling numerical calculation model of dry-type air-core shunt reactor is established.The model is under the constraint of external circuit and the spacers between encapsulations are considered as well as the rainhat on the reactor.The loss of encapsulation calculated in electromagnetic field is imported into fluid-temperature field calculation as a heat source.Because the conductivity of the conductor is related to temperature,the encapsulation loss is iteratively calculated in the electromagnetic-fluid-temperature field.In this method,temperature distribution of dry-type air-core reactor is obtained.Compared with the infrared measuring temperature rise,the temperature rise error of the model without spacers nor rainhat is as high as 9％,however the accuracy of the calculation model considering spacers and rainhat is much better,with temperature rise error less than 3％.The temperature distribution analysis of the reactor encapsulation in the axial and radial on the top can provide a theoretical basis for dry-type air-core shunt reactor in product design and temperature rising online monitoring.关键词
