(I) Compensation transformer
The compensation transformer is actually a three-phase dry-type transformer with the main winding.
(Two) contact voltage regulator
The contact voltage regulator is a three-phase transformer that can smoothly regulate the output voltage. Corresponding to three phases, it can smoothly adjust the output voltage to achieve the function of changing the primary coil voltage of the compensation transformer, thereby maintaining the output voltage of the compensation transformer.
(Three) contact voltage regulator
The controller includes voltage detection and comparison, logic processing, servo drive, and complete machine protection.
The voltage regulator is composed of voltage regulation circuit, voltage detection circuit, servo system and control loop. The wiring diagram of its electrical principle is as follows:
与补偿变压器C组成。 The voltage regulation circuit is composed of a contact voltage regulator B and a compensation transformer C. The input of the contact voltage regulator is connected to the output of the voltage regulator, and the output is connected in series to the primary coil of the compensation transformer, and the secondary coil of the compensation transformer is connected in series to the main circuit.
Excluding the impedance voltage drop of the compensation transformer
¡À Uc U2 = U1 ¡À Uc
In the formula:
稳压器输入相电压 U1— Regulator input phase voltage
稳压器输出相电压 U2-- Regulator output phase voltage
稳压器一相补偿电压 Uc —One-phase compensation voltage of voltage regulator
改变△ U1时，若补偿电压Uc相应改变△ Uc ，且△ U1= △ Uc ，输出相电压U2便可保持不变，补偿电压Uc的变化时根据接触调压器的输出电压来改变。 When the input phase voltage U1 changes △ U1 , if the compensation voltage Uc changes correspondingly △ Uc and △ U1 = △ Uc , the output phase voltage U2 can remain unchanged. According to the change of the compensation voltage Uc according to the output voltage of the contact regulator To change. The contact voltage regulator automatically changes the output voltage according to the change of the output voltage by the electronic logic control circuit.
