No matter what line the silicon element works in, it must be ensured that the effective current of the silicon element does not exceed the rated forward average current I of the silicon element. The rated forward average current I of the silicon element is measured under the condition of a single-phase sinusoidal half wave . The current waveform is different in various rectifier circuits. Therefore, it is quite complicated to calculate the effective value of the current flowing through the silicon element. In fact, when selecting silicon components, formula (2) is generally used: where: I: the average value of the maximum rectified current allowed by the rectifier A ;: the rated forward average current A of the silicon component; K: silicon flowing through different rectifier circuits The form factor of the element: the parallel conduction number of the silicon element.
Line name Single-phase half-wave single-phase full-wave single-phase bridge three-phase half-wave three-phase bridge with balanced reactor Double reverse star Friends of Science electrical equipment maintains a stable operating state and working state, making it easier Management and maintenance can also improve the capacity of the equipment and extend the life of the equipment. The equipment is in good condition, which can save the production cost of coal mines, maintain the safe operation of coal mine work, improve the economic benefits of coal mines, and thus enhance the competitiveness of coal mine enterprises.
In the silicon rectifier of the small hoist, a single-phase rectifier transformer is used to increase the 220V voltage of the AC power grid to 250V to supply power to the silicon rectifier. The rated forward average current I of the silicon element is obtained from the table. : So: I reverse the peak operating voltage U of silicon components. For single-phase bridge rectifier circuit: U auntie E: U. The silicon rectifier can choose 8 (two sets) rated forward average current as 5A, reverse working peak voltage 550V silicon diode, its model is 2CZ5 / 550.
