SR6123E Three Phases Induction Voltage Regulator Electrical Trainer Vocational Educational Equipment
1 Introduction
The three-phase self-coupling voltage regulator is essentially a self-coupling transformer with continuous voltage regulation. There are two types of core – ring and column. The column core is similar to the general transformer, and it is made of silicon steel. The ring core is rolled with a silicon steel strip. 20kVA and the following small capacity self-coupling voltage regulator, more choose ring type iron core; More than 20kVA users adopt column core. In the structure of the ring-type autovoltage regulator, the winding is wrapped in a single layer of insulated copper wire around the ring core. The surface of the coil is polished to a smooth surface, and the brush with the electrochemical graphite is in contact with it. The brush can be used to rotate the surface of the wire to change the output voltage. If the current capacity is greater than 10A, it can be used in parallel with two or more brushes. The self-coupling voltage regulator is generally made from cold and dry. Oil immersion is also used in special occasions with large capacity or special circumstances. Three ring – type single – phase self – coupling voltage regulator can be composed of three – phase self – coupling voltage regulator.
