【技术实现步骤摘要】
一种新型水冷单相交流电抗器
本技术涉及电抗器领域,特别涉及一种新型水冷单相交流电抗器。
技术介绍
在目前市场上应用的电力电子系统中单相交流电抗器,要求体积小、重量轻、散热好,通常采用自然风冷结构。此结构要求线圈内部及线圈与铁芯间预留通风通道,而通风通道要靠在制程中放入绝缘撑条来支持,这样做就存在以下缺点:1.人工及设备成本高,在绕线时要加绝缘撑条做通风通道,每次都需要停机并花费工时;2.材料成本增加,绝缘撑条属于绝缘材料,增加绝缘撑条就增加绝缘材料成本。3.产品体积大,由于绝缘撑条厚度一般都不小于6mm(小于6mm空气阻力大不能形成对流),所以产品内部增加一个通风通道就增加了一个尺寸(6mm及以上)。4.产品整体温升均匀性差,由于通风通道内温升与通风通道的宽度、长度及深度都有关系,每个通风通道尺寸不可能完全一样,所以每个通风通道的温度也不一样,一般温差在10-30℃。
