技术领域technical field
本实用新型涉及变压器技术领域,特别涉及一种立体卷铁心变压器。The utility model relates to the technical field of transformers, in particular to a three-dimensional wound iron core transformer.
背景技术Background technique
立体卷铁芯变压器具有磁阻小,空载损耗低,节能效果显著,噪音低,结构紧凑、体积小等特点,正得到广泛的应用。变压器运行发生短路时,线圈流通短路时的大电流,在漏磁场的作用下,线圈受到电磁力。根据左手定则。在横向漏磁场的作用下,高低压线圈均受到轴向方向的电磁拉伸力。The three-dimensional wound iron core transformer has the characteristics of small reluctance, low no-load loss, remarkable energy saving effect, low noise, compact structure and small size, and is being widely used. When a short circuit occurs in the operation of the transformer, the coil flows a large current during the short circuit, and under the action of the leakage magnetic field, the coil is subjected to electromagnetic force. According to the left hand rule. Under the action of the transverse leakage magnetic field, the high and low voltage coils are subjected to electromagnetic tensile force in the axial direction.
三角结构的立体卷铁心变压器的线圈为圆形,但由于一般的立体卷铁心变压器低压线圈采用多根电磁线组合并绕,绕制完成后在端部形成螺旋角,低压线圈在横向漏磁场下收到较大的轴向力,若无有效处理,容易造成线圈轴向崩塌,此时由于铁心为卷绕后按三角布置立体拼接,无法保证线圈的轴向夹紧力,造成立体卷铁心变压器的承受突发短路能力差。The coil of the three-dimensional wound iron core transformer with triangular structure is circular, but because the low-voltage coil of the general three-dimensional wound iron core transformer uses a combination of multiple electromagnetic wires and is wound in parallel, a helix angle is formed at the end after the winding is completed, and the low-voltage coil is under the transverse leakage magnetic field. If a large axial force is received, if there is no effective treatment, it is easy to cause the axial collapse of the coil. At this time, since the core is three-dimensionally spliced in a triangular arrangement after winding, the axial clamping force of the coil cannot be guaranteed, resulting in a three-dimensional wound core transformer. The ability to withstand sudden short circuit is poor.
传统立体卷铁心变压器的线圈为常规绕制,未作加强处理,轴向抗冲击力差;其次结构支撑件为碳钢材料轻量化设计,一般钢件焊接拼接,强度较差,且生产工序长,成本高,且不环保。经工艺处理后,再吊入油箱,总装配成油浸式变压器。目前的油浸式变压器大多采用平面叠铁心结构,空载损耗相对较高,同时抗短路能力也叫差。The coils of the traditional three-dimensional wound iron core transformers are conventionally wound, without reinforcement treatment, and the axial impact resistance is poor; secondly, the structural supports are lightweight carbon steel materials, and the general steel parts are welded and spliced, which has poor strength and long production process. , the cost is high, and it is not environmentally friendly. After technical treatment, it is hung into the oil tank and assembled into an oil-immersed transformer. Most of the current oil-immersed transformers use a flat laminated core structure, which has relatively high no-load loss and poor short-circuit resistance.
