Supply DETSC dynamic reactive power compensation device for you

The series of low-voltage thyristor reactive power compensation devices is a new type of electronic non-contact thyristor capacitor switching device with dynamic tracking compensation. It uses high-power thyristors to form a low-voltage bidirectional thyristor AC non-contact switch, which can realize multi-function switching. Fast zero-crossing switching of the capacitor bank. Connecting an appropriate inductor in series with the capacitor branch of the device can effectively prevent harmonic amplification and absorb part of the harmonic current and play the role of harmonic suppression. At the same time, this series of devices adopts three-phase independent control technology, which can effectively solve the technical problem of reactive power compensation for three-phase unbalanced impact loads. The device response time is less than 10% and the power factor compensation is more than 10%. It is an upgraded product in the field of reactive power compensation. Technical features rr uses bidirectional anti-parallel thyristors to achieve contactless electronic switches and extend the service life of the switch.
Achieve zero-crossing switching without impact, no inrush current and over-voltage.
It can carry out three-phase common compensation for three-phase balanced power grids and phase-separated compensation for three-phase unbalanced load power grids.
Fully digital control, real-time detection and calculation of reactive power.
The switching speed is fast.
Within the specified dynamic response time, multi-level compensation is in place at one time, and the power factor after compensation is greater than.
Quick fuse overcurrent protection and alarm.
It will automatically exit in the event of external failure or power outage, and will automatically resume operation after power is supplied.
The first domestically created dynamic reactive power compensation regulator system in this field has strong anti-interference ability and high reliability.
 There are power system problems such as frequent fluctuations and reactive power backflow.
Working principlerr
The low-voltage dynamic reactive power compensation device is controlled by artificial intelligence and consists of a controller, a triac, a capacitor, a reactor, and a protection element. The controller tracks and measures the power factor and reactive current of the load in real time, compares it with the preset given value, and dynamically controls the switching of the capacitor bank to ensure that the power factor reaches the set value. The entire measurement execution process is completed within one cycle (time <), and the zero-crossing trigger of the thyristor is realized to ensure that the switching capacitor has no impact, no inrush current, and no transition process.
Scope of application
This product is widely used in metallurgy, chemical machinery, manufacturing, rail transportation, mining, port transportation, large-scale cultural and sports venues, commercial residences and other industries. It can effectively solve power quality problems such as low power factor of the power system, frequent harmonic load fluctuations, and frequent reactive power impact, unbalanced operation of the three-phase system, and improve the operating efficiency of the power system.
