Description
技术领域 technical field
本实用新型涉及变压器技术领域，特别是涉及一种干式牵引整流变压器。 The utility model relates to the technical field of transformers, in particular to a dry-type traction rectifier transformer.
背景技术 Background technique
变压器是变换交流电压、电流和阻抗的器件，当初级线圈中通有交流电流时，铁芯（或磁芯）中便产生交流磁通，使次级线圈中感应出电压（或电流）。变压器由铁芯（或磁芯）和线圈组成，线圈有两个或两个以上的绕组，其中接电源的绕组叫初级线圈，其余的绕组叫次级线圈。在发电机中，不管是线圈运动通过磁场或磁场运动通过固定线圈，均能在线圈中感应电势，此两种情况，磁通的值均不变，但与线圈相交链的磁通数量却有变动，这是互感应的原理。变压器就是一种利用电磁互感应，变换电压，电流和阻抗的器件。 A transformer is a device that transforms AC voltage, current, and impedance. When an AC current passes through the primary coil, an AC magnetic flux is generated in the iron core (or magnetic core), which induces a voltage (or current) in the secondary coil. The transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called the secondary coil. In a generator, whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains the same, but the amount of magnetic flux intersecting the coil is different. Change, this is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current and impedance.
在城市轨道中，根据电力负载的特点，往往采用12脉波的干式牵引整流变压器。但是，存在以下的缺点：12脉波的干式牵引整流变压器对电网的谐波污染严重，需要在电网中加装滤波装置；输出电压（电流）波形不平滑。 In urban rail, according to the characteristics of the electric load, a 12-pulse dry-type traction rectifier transformer is often used. However, there are the following disadvantages: the 12-pulse dry-type traction rectifier transformer has serious harmonic pollution to the power grid, and a filter device needs to be installed in the power grid; the output voltage (current) waveform is not smooth.
