Integrated na Masintelekto nga Kapasitor

Paggamit

Ang serye ng integrated intelligent power capacitors na ito ay isang ligtas, maasahan, mataas na epektibong at energy-saving na pag-install sa reactive power compensation device. Ang layunin nito ay bawasan ang transformer loss, ang line loss ng power supply line, mapabuti ang power factor ng power system at mapabuti ang grid power. Ito ang pangunahing komponente ng bagong henerasyon ng high-quality reactive power compensation equipment. Maaari rin itong gamitin bilang isang maliit na compensation device na may independent automatic control function.

Ang produkto ay binubuo ng: measurement and control unit, capacitor switching switch at arc extinguishing unit, comprehensive protection unit (kasama: system harmonic voltage/current limit, overvoltage/undervoltage, small current blocking, compensation for branch overcurrent and unbalance, pre-warning at protection functions ng data information tulad ng over-temperature at over-pressure sa loob ng capacitor), working status indicator unit, low-voltage parallel capacitor (hanggang 8 capacitors), circuit breaker, housing at communication terminals at iba pang functional components, na nabuo pagkatapos ng optimized combination ng isang highly intelligent product na may integrated mechatronics.

Ang paggamit ng produktong ito ay nagbago ang bulky at cumbersome structure at assembly process ng traditional reactive power compensation device, kaya ang bagong henerasyon ng low-voltage reactive power compensation device ay may: mas magandang compensation effect, mas maliit na sukat, mas mababang power consumption, at mas flexible na paggamit, mas madaling assembly at maintenance, mas mataas na operational reliability, mas matagal na service life, atbp.
