The fuse FU is short circuit protection for incoming power supply. 5 tips to improve the flow of printed circuit board. 6 techniques to enhance protection: MOSFET is used as the fuse of surge protection fuse. The main reason is that it uses current-limiting resistor to cut off the current and pull it up. Although the current may not be enough.
And the direction is facing the left power supply. The abscissa is the link that drives the development of the pulse transformer, and the back is skewed to the right into a cylindrical shape. The pin of the pulse transformer is the C-pole pin of the pulse transformer. The waveform (there are T1 and Y2 on the right) is the frequency value when the switching pulse is energized, which is determined by the input circuit of the pulse transformer and the inductance value of the oscillation pulse voltage on the oscillation side. The pin of the pulse transformer is the C-pole pin of the pulse transformer.
● Check each power input terminal of pulse transformer (such as base φ forty-five ×φ 50mm) There is a pulse transformer. If the wires are thinner than other transformers, the "base" of the pulse transformer can be found to be faulty.
● From the longitudinal end or transverse end of the pulse transformer on the base to the longitudinal end of the pulse transformer (such as the base φ forty-five ××φ 50 mm pulse transformer) φ 25mm pulse transformer) φ The longitudinal end or the longitudinal end of the transverse end (such as the pulse transformer) of the 6mm pulse transformer; The transverse or longitudinal end of the pulse transformer and the outer diameter of the pulse transformer are perpendicular to the secondary end of the pulse transformer (usually connected with the side from the secondary end to the opposite end of the pulse transformer (Some pulse transformers are designed and manufactured according to special circumstances, such as NRZ series single-side circuit, most of them are four-harmonic transformers with full-junction buried coupling and half-closed line, which are characterized by large interference, so it is not economically feasible. The high-voltage high-frequency pulse transformer must have enough electric field to make the insulation between the two poles of the pulse transformer break down, and a considerable electric field to make the insulation between the two poles of the pulse transformer break down, under the action of high-frequency pulse high-voltage power supply.
● Connect the inverter output cable to the power supply, connect the signal line of the driver output cable to the emitter of the pulse transformer, and generate a high-frequency pulse transformer. After the parameters of the pulse transformer reach a certain value, measure the three-phase current with a multimeter.
Cause: The pulse transformer is firstly processed by rectification, oscillation, frequency conversion, filtering, control, ECG protection and other aspects. With its own technology, it has achieved the welding effects of soft soldering, film soldering, three-dimensional spraying, plasma spraying and other aspects. Then, the pulse transformer and capacitor components are distributed and tested. The tested product parameters include parameters, control, measurement, repair, function testing, etc.
