VAMP弧光保護
  • 特點

    Schneider Electric VAMP系列是弧光檢測和保護的先驅,提供快速和可靠的設備,以提高安全性 在世界各地的服務接近10000弧光閃光系統,從單一的弧光保護單位為多區域弧光系統。

    弧光會引起開關設備故障的高熱及壓力,它不僅會造成停電,但它也可能會導致業務大量物質損害的損失和可能嚴重危及操作人員的安全。VAMP的弧光檢測和保護系統故障的措施,通過弧光偵測器通道的電流和光,應在故障發生時,最大限度地減少通過快速切斷電流供給弧光燃燒時間。傳統的弧光保護方法不提供足夠快的保護和短弧光燃燒時間是至關重要的,特別是當弧光在維修過程中開發的開關設備,危及人身安全和壽命。獨特的弧光故障的功能增加了安裝的總安全和電力系統保護電驛的可靠性,一個新的層面。保護您的資產,員工的安全和你的電源系統的未來性VAMP的超快速的弧光保護產品。.

    施耐德電氣最新推出的產品是創新的VAMP321。結合VAMP 50 and 200 系列可靠的技術和VAMP 221 弧光保護系統,VAMP 321 提供了一個安全,技術先進的解決方案。

    Total fault clearing time typically:

    • Outgoing feeder 50 (relay) + 60 (CB)
      = 110 ms (+ Auto-reclosing)
    • Incoming feeder 350 (relay)+ 60 (CB)
      = 410 ms
      Resistance Earthed Network
    • Earth-fault relay operation times are typically
      set high, thus burning times of high-impedance
      type arc faults are prolonged.
    Typically the burning time of an arc fault should be limited to less than 100 ms in order to avoid major damage. Burning times of nearly half a second will most certainly cause considerable damage in the switchgear installation.

    Total fault clearing time typically:

    • Outgoing/ingoing feeders 7 ms (relay) + 60 ms (CB)
      = 67 ms
      Resistance Earthed Network
    • Fault clearance in 57 - 67 ms
    The conventional MV protection schemes have traditionally been complemented by implementing busbar differential schemes. The differential scheme implementations are typically expensive due to extra CT’s needed and complicated engineering and wiring. Busbar protection systems based on interlockings are slow, minimum operating time usually being 100 ms + CB time. A modern arc protection system provides though a very cost-effective high-speed busbar protection for air insulated MV switchgears.
