浅析稳压变压器的工作原理

稳压变压器,是将稳压器和变压器安装在一个机箱内,采用模组化配置布线,使得稳变压器设备在维护保养上均非常方便。且节省空间降低购买成本和降低线损提供效率,可承受瞬间高电压、大电流及恶劣的温度、湿度、震动环境。
The voltage stabilizing transformer is to install the voltage regulator and the transformer in a case, and adopts the modular configuration wiring, so that the transformer maintenance equipment is very convenient in maintenance. And save space, reduce purchasing costs and reduce line loss to provide efficiency, can withstand the moment high voltage, high current and bad temperature, humidity, vibration environment.
稳压变压器组成部件
Component component of voltage stabilizing transformer
济南变压器厂http://www.jnwdsh.com/稳变压器一体机主要由铁心,初级绕组,次级绕组,磁分路,谐振电容器,补偿绕组组成。
The transformer stabilizing machine mainly consists of an iron core, a primary winding, a secondary winding, a magnetic shunt, a resonant capacitor and a compensating winding.
稳压变压器工作原理
Working principle of voltage stabilizing transformer
稳压变压器空载时,假设初级电压为U1,电流为I1,圈数为N1,则磁通为I1N1,由于漏磁通回路有空气间隙,而空气磁阻较大,所以大部分磁通通过次级线圈闭合,漏磁很少。
The no-load voltage stabilizing transformer, assuming the primary voltage U1, current I1, coil number N1, it is I1N1 due to magnetic flux leakage flux, loop air gap and air reluctance larger, so most of the magnetic flux through the secondary coil closed, little magnetic leakage.
稳压变压器在有负载时,次级有电流I2流过,次级匝数为N2,次级磁通势为I2N2。变压器铁心磁通,初级次级共同产生,次级磁通也可分为一部分,一部分与初级匝连成主磁通,另一部分通过漏磁铁心只与次级匝连或为漏磁阻,次级所产生的主磁通和初级相反。

When the load transformer is in load, the secondary current is I2, the secondary turns are N2, and the secondary magnetic flux is I2N2. The transformer core flux, common primary secondary, secondary flux can also be divided into a part, and a part of primary turns into the main flux, partly by magnetic leakage and secondary windings or even the only core for leakage reluctance generated by the main flux, secondary and primary instead.
在一般变压器中,次级产生的反相磁通,初级电流会就此增加以抵消次级磁通,使主磁通基本保持不变。
In a general transformer, the secondary reverse magnetic flux is generated, and the primary current is increased to counteract the secondary flux, which essentially keeps the primary magnetic flux constant.
而在稳压变压器中,由于有磁分路的存在,有同样的次级电流时,产生同样的漏磁通,但一部分成为漏磁通,有一部分去抵消初级线圈中的主磁通,由于抵消部分较少,所以初级电流增加很少,真正用于建立次级主磁通也就减少了。
In the voltage transformer, the magnetic shunt, a secondary current same, produce the same flux, but to become a part of the flux leakage part to offset the main magnetic flux in the primary coil, the offset part is less, so the primary current increases little, really used to establish a secondary main flux is reduced.

Working performance of voltage stabilizing transformer
由于谐振线圈的存在,所产生的电流形成磁通与主磁通同相,使次级工作在深饱和状态,而初级工作在非饱和状态,形成一个基本稳定的交变磁场磁路。再加上补偿线圈Nk与次级线圈串联(反极性),这样就确保了当输入电压在一定范围内变化时,次级输出电压基本不变时,从而实现输出电压的稳定性。
Due to the existence of the resonant coil, the current generated by the formation of magnetic flux and magnetic flux phase, the secondary working condition in deep saturation, and the primary work in non saturation, forming a stable alternating magnetic field magnetic circuit. Coupled with the compensation coil and the secondary coil of Nk series (reverse polarity), thus ensuring that when the input voltage changes within a certain range, the secondary output voltage unchanged, in order to achieve the stability of the output voltage.
