Thyristor module pulse trigger system in the field of electrical, electronic and other industrial (
Active such as rectifier, inverter, ac voltage regulator, inverter and chopper etc. )
Has a very broad application.
And pulse can trigger system in practical application at the normal and reliable operation, to a large extent depends on the system the anti-interference ability of various kinds of interference on the spot.
Because most of the interference of instantaneous peak signal in the form of the so-called & other;
Burrs & throughout;
, when its amplitude and energy reaches a certain degree, is easy to cause the thyristor
module to mislead, thyristor module damage and other serious consequences, the system can not run normally.
Especially in the field environment is bad, and the pulse itself to trigger pulse case, because the outside world on the pulse system and pulse interference between each other is bigger, the anti-interference ability of the system, the more become one of the key.
The case system anti-interference ability strong or weak is also can measure the stand or fall of an anti-interference measures the actual effect.
Such as dc steelmaking eaf of thyristor modules, rectifier device that belongs to this kind of strong trigger system.
Dc arc furnace rated flow of thousands to tens of thousands of Ann, arc pressure for hundreds of volts, and short circuit in dc side is the normal condition, the working condition in melting period occurred frequently, in the process of phase shift control, produce strong harmonic current, the arc by a flow path, such as rectifier device, short_net, dc furnace produce strong upheaval around space electromagnetic fields, under the pulse system become a strong interference source.
In addition, due to large rectifier equipment capacity, need more than just thyristor module parallel operation, strong reason to trigger pulse to ensure thyristor module in parallel conduction of consistency, reliability, and pulse instantaneous power is larger, the pulse interference between each other is also increased.
Zhejiang rectifier co. , LTD. , the production of various kinds of specifications models of thyristor module, thyristor module, solid state relay module, rectifier bridge module, such as supporting the radiator products, sincerely look forward to the cooperation with various companies and procurement staff, to provide affordable, quality and reliable electronic components.
