2019-9-28Power supply type and characteristics
Power supply type and characteristics The classification of commonly used power transformers can be summarized as follows: 1. According to the number of phases: (1) Single-phase power transfo -
2019-9-28working principle
1. It is a special transformer that outputs and inputs a set of coils. Boost and step-down are realized by different taps. The tap voltage is lower than that of the shared coil. The tap voltage is hig -
2019-9-28Variator function
The most basic type of power transformer consists of two sets of coils wound with wires and they are inductively coupled together. When an alternating current (having a certain known frequency) flows -

Transformer loss
When the primary winding of the power transformer is energized, the magnetic flux generated by the coil flows in the core. Since the core itself is also a conductor, a potential is induced in a plane -

The higher the silicon content of the silicon steel sheet of the power transformer core, the better? It is not seen that the amount of silicon contained in the silicon steel sheet has little effect -
2019-9-28What is the focus on the silicon steel sheet material in the power transformer?
What is the focus on the silicon steel sheet material in the power transformer? Since the loss of silicon steel in the alternating magnetic field is small, the power transformer mainly uses silicon -

Transformer detection
First, the detection of the power transformer in the middle week: A. Dial the multimeter to R×1 block, and check the on/off condition of each winding one by one according to the arrangement rules o -
2019-9-28Charger test
Charger test 1. Check if there is any obvious abnormality by observing the appearance of the transformer. If the coil lead is broken, de-soldering, whether the insulating material has burnt marks, -
2019-9-28Detection of no-load current of the transformer.
(1) Direct measurement method. Open all the secondary windings and place the multimeter in the AC current block (500mA, stringed into the primary winding. When the plug of the primary winding is inser -
2019-9-28How to identify the transformer
How to identify the transformer 1) Identification from the shape The core of the common power transformer has two types: E-shaped and C-shaped. The E-shaped iron core transformer has a shell s -
