Integradong Intelligent Power Capacitor

Panggamit

Ang serye ng integrated intelligent power capacitors na ito ay isang ligtas, maasahan, mataas na epektibong at mapagkakatiwalaan na instalasyon na nakalagay sa reactive power compensation device. Ang kanyang tungkulin ay bawasan ang pagkawala ng transformer, ang pagkawala ng linya ng power supply line, palakasin ang power factor ng power system, at palakasin ang kalidad ng grid power. Ito ang pangunahing komponente ng bagong henerasyon ng high-quality reactive power compensation equipment. Maaari din itong gamitin bilang isang maliliit na compensation device na may independent automatic control function.

Ang produkto ay binubuo ng: measurement and control unit, capacitor switching switch and arc extinguishing unit, comprehensive protection unit (kasama: limit ng system harmonic voltage/current, overvoltage/undervoltage, small current blocking, compensation for branch overcurrent and unbalance, pre-warning at proteksyon 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 naging isang highly intelligent product na may integrated mechatronics pagkatapos ng optimized combination.

Ang paggamit ng produktong ito ay nagbago ang bulky at cumbersome na estruktura at proseso ng assembly ng traditional reactive power compensation device, kaya ang bagong henerasyon ng low-voltage reactive power compensation device ay may: mas mahusay na 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.
