電弧光保護(hù)系統(tǒng)使用先進(jìn)的處理器技術(shù)來控制系統(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。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到電弧光，并且電流單元的整定的電流定值被超過，電弧光保護(hù)系統(tǒng)的跳閘信號將在極短時(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流的信息。如果偶爾光線信號超過光線設(shè)定值或者電流信號超過電流設(shè)定值，系統(tǒng)不會輸出跳閘信號，也不會記憶在跳閘回路中，但是在主控單元上會顯示報(bào)警信號。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)來向主控單元傳輸跳閘信號，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)，跳閘信號可以非常迅速的輸出到斷路器。弧光保護(hù)裝置專業(yè)銷售。</p><div
