A06B-6132-H002產(chǎn)品介紹:
我公司研制生產(chǎn)的TXK系列消弧消諧及過電壓保護(hù)柜是根據(jù)傳統(tǒng)的消弧及過電壓保護(hù)柜及消弧線圈的優(yōu)缺點(diǎn),研制開發(fā)出的新型產(chǎn)品??刂茊卧捎秒pCPU工作,主CPU采用32位DSP,將DSP技術(shù)用于電網(wǎng)消弧裝置,利用DSP的快速、確的數(shù)據(jù)處理能力,實(shí)現(xiàn)傅立葉分析,通過對(duì)系統(tǒng)母線三相電壓及頻率等參數(shù)的分析,確地判斷出:電網(wǎng)弧光接地、過渡過程及單相金屬接地。裝置可根據(jù)用戶要求投退相應(yīng)設(shè)備,引入電流量作為判據(jù),實(shí)現(xiàn)多種閉鎖功能,確保系統(tǒng)供電可靠。
裝置主要由三相組合式過電壓保護(hù)器TGB、可分相控制的高壓真空接觸器JZ、微機(jī)控制器TXK3800、高壓限流熔斷器組件FU、高頻阻尼元件FZ及帶有輔助二次繞組的電壓互感器PT等組成。旦系統(tǒng)發(fā)生單相弧光接地,微機(jī)控制器TXK3800立即判別故障類型和相別并向故障相的真空接觸器JZ發(fā)出動(dòng)作指令,真空接觸器JZ快速將故障相通過高頻阻尼元件接地。真空接觸器動(dòng)作之前的過電壓由三相組合式過電壓保護(hù)器TGB限制在較低的數(shù)值。當(dāng)由于裝置故障、檢修調(diào)試人員誤接線等原因造成裝置誤判斷,導(dǎo)致相間弧光短路時(shí),F(xiàn)U組件可以在2mS之內(nèi)快速熔斷,短路電流遠(yuǎn)沒有達(dá)到大值,不會(huì)造成任何后果,對(duì)系統(tǒng)的運(yùn)行沒有影響。
