摘要
一体化智能型JB柜电力电子装置能够对无功、不平衡、谐波等多种电能质量问题进行有效治理。针对一体化智能型JB柜物理空间有限且滤波装置中的空心电抗器体积较大的问题,提出一种将滤波空心电抗器集成于配电变压器的方案,并将其应用于JB柜中,可减小装备的占地面积,同时也提高了一体化智能型JB柜的集成度。对配电变压器集成滤波电抗器的绕组结构布置、电磁解耦电路、集成滤波电抗器的电感值计算方法进行详细介绍,并对该新型配电变压器进行三维有限元建模及仿真。结果表明,集成滤波空心电抗器与变压器绕组之间具有良好的低耦合度和高解耦度,计算所得滤波电抗器的电感值偏差在国家标准允许的范围内,验证了集成滤波电抗器配电变压器模型的正确性。
The power electronic device in the integrated intelligent JB cabinet can effectively deal with the power quality problems such as reactive power,unbalance,harmonic and so on. Aiming at the problem of limited physical space of integrated intelligent JB cabinet and the large volume of the air-core reactor in the filtering device,a scheme of integrating air-core reactor into distribution transformer is put forward and applied in JB cabinets,which can reduce the equipment area and improve the integration of integrated intelligent JB cabinet. The winding structure arrangement,the electromagnetic decoupling circuit and the inductance calculation method of integrated filtering reactor are introduced in detail. The three-dimensional finite element modeling and simulation of the new distribution transformer are presented. The results show that,there is a good low-coupling and high-decoupling between the integrated filtering air-core reactor and the transformer winding,and the calculated inductance deviation of the filter reactor is within the allowable range of the national standard,which verifies the correctness of the model of distribution transformer integrated with filtering reactor.
