Many people have only seen the computer mainframe casing designed for mining dry-type transformers, but what is the structure and manufacturing principle inside?
Briefly speaking, in the diesel generator, whether the movement of the electromagnetic coil is based on the magnetic field or the movement of the magnetic field is based on the fixed electromagnetic coil, the potential difference of the coil can be induced in the electromagnetic coil. In both cases, the magnetic flux value is always the same, but the number of the magnetic flux of the cross chain with the electromagnetic coil has changed, which is the basic concept of mutual inductance. The mining dry-type transformer is a kind of mutual induction of magnetic effect of applied current, An electronic device that converts the working standard voltage, current value, and impedance.
Hengfengshuai Electric has corresponding technical requirements for different types of mining dry-type transformers, which can be explained with corresponding basic parameters. The main technical parameters of mining transformers for switching power supply circuits include: high power, rated voltage to working standard voltage ratio, rated current output power, working temperature level, temperature rise, voltage regulation rate during operation, insulation performance, and moisture-proof characteristics. For general low-frequency mining transformers, the key parameters are: DC switching power ratio, working frequency characteristics, non AC and communication frame loss, magnetic shielding materials, and tip discharge Efficient, etc.
When the power P2 of the mining dry type transformer is equal to the actual power P1, the mining transformer does not cause any losses. But in reality, this type of mining transformer does not exist. When the DC circuit is based on a mining transformer, the transmission of electrical energy by the mining transformer can lead to losses, mainly including copper losses and magnetic losses.
According to the magnetic induction line of the ferrite core of a mining dry type transformer, its position and specifications will also change, promoting the friction between the molecular formulas of the internal structure of the iron core and releasing heat, thereby consuming a portion of electrical energy, which is called hysteresis loss. Another is eddy current loss. When a mining transformer is working, the transformer coil contains magnetic induction lines that flip over, causing induced current to the extent perpendicular to the magnetic induction line, Due to the opening of a closed circuit, this current value creates an electrostatic field in the form of vortices, hence it is called eddy current. The birth of vortices causes the transformer coil to heat up and consume mechanical energy, which is called eddy current loss.
