Description
PRODUCT INTRODUCTION:
Our company research and develop a new power supply equipment which is the stabilizer & transformer integrated machine. With modular wiring design, the stabilizer & transformer integrated machine combines the voltage regulator and transformer in one cobinet. Indeed, the maintenance of the stabilizer & transformer integrated machine is going to be very convenient. Compared with normal type of regulator, there are more advantages such as saving space, reducing purchase cost, decreasing line power loss, and improving efficiency. Also, it can withstand transient high voltage and large current. In the extreme harsh situation, as like harsh temperature, humidity, and vibration, the machine still is reliable. Because of stabilized accuracy and transformed voltage range, especially, for the expensive, accurate, and imported equipment, the stabilizer & transformer integrated machine is necessary.

MODLE DESCRIPTION:

PRINCIPLE:
When the stabilized variable integrated machine is no-load, assuming that the primary voltage is U1, the current is I1, and the number of turns is N1, the magnetic flux is I1N1. When the voltage stabilizing transformer is under load, there is a secondary current I2 flowing through it, with a secondary turn number of N2 and a secondary magnetic flux potential of I2N2. The magnetic flux of the transformer core is generated jointly by the primary and secondary windings, and the secondary magnetic flux can also be divided into two parts. One part is connected to the primary turn to form the main magnetic flux, and the other part is connected to the secondary turn or to form the leakage magnetic resistance through the leakage magnetic core. The primary magnetic flux generated by the secondary is opposite to the primary magnetic flux. In general transformers, the secondary phase inversion magnetic flux is generated, and the primary current will increase to offset the secondary magnetic flux, keeping the main magnetic flux basically unchanged. In an all-in-one machine, due to the presence of magnetic shunts, the same secondary current produces the same magnetic leakage flux. However, one part becomes the leakage flux, and the other part counteracts the main magnetic flux in the primary coil. Due to the small amount of counteraction, the primary current increases very little, and the actual use for establishing the secondary main magnetic flux decreases.
