電弧光保護(hù)系統(tǒng)使用先進(jìn)的處理器技術(shù)來(lái)控制系統(tǒng)的功能。該處理器技術(shù)也使得電弧光保護(hù)系統(tǒng)功能的編程，可匹配開關(guān)柜的不同運(yùn)行方式。在跳閘回路里采用的半導(dǎo)體技術(shù)（可控硅開關(guān)）確保了開關(guān)柜里的供電開關(guān)以**小的延時(shí)得到跳閘信號(hào)。在不論是KEATON電弧光保護(hù)系統(tǒng)的主控單元，還是電弧光單元探測(cè)到電弧光，并且電流單元的整定的電流定值被超過(guò)，電弧光保護(hù)系統(tǒng)的跳閘信號(hào)將在極短時(shí)間內(nèi)到達(dá)供電開關(guān)。 </p> <p> 電流的信息也可直接取自安全電流回路，在此情況下，電弧光保護(hù)也可盡可能快的得到過(guò)流的信息。如果偶爾光線信號(hào)超過(guò)光線設(shè)定值或者電流信號(hào)超過(guò)電流設(shè)定值，系統(tǒng)不會(huì)輸出跳閘信號(hào)，也不會(huì)記憶在跳閘回路中，但是在主控單元上會(huì)顯示報(bào)警信號(hào)。在編程的時(shí)候，需要考慮系統(tǒng)按照用戶所希望的方式正常工作。采用光纖技術(shù)來(lái)向主控單元傳輸跳閘信號(hào)，確保了電弧光保護(hù)系統(tǒng)的完美功能，它的抗干擾能力強(qiáng)，跳閘信號(hào)可以非常迅速的輸出到斷路器。
