摘要:
文中綜合分析了現有SF6氣體密度繼電器存在的怕振動和漏油的問題。爲了解決這些存在的問題,提出並研制了無油抗振型SF6氣體密度繼電器,該密度繼電器不用充防振用的硅油來實現抗振,而是設計了防誤動作機構,在開關分合閘産生的沖擊和振動時,該防誤動作機構使密度繼電器的微動開關(信號接點)遠離發生誤動作的位置,避免出現誤動作,徹底使密度繼電器躲過受到的沖擊振動的影響,避免在氣體密度正常時誤觸發信號(微動開關),保障電網安全運行。經過2年多的現場應用證明性能可靠、滿足無油和斷路器重合閘要求。
Abstract:
In this paper,the problems of the existing SF6 gas density monitor that they are prone to vibration and oil leakage are analyzed. In order to solve these problems,oil free vibration resistance type SF6 gas density moni-tor is proposed and developed. Vibration resistance is not achieved by silicon oil filling in this density monitor, but the design of the tripping preventing system. The shock and vibration are generated when the switchgear opens and recloses,the micro switches(contacts)are physically brought away from where they can possibly trip so as to avoid undesired operation. In this way,the density monitor escapes from the impact of shock and vibration and avoids giving a signal(micro switch)when gas density is normal,and the safe operation of the power network is maintained. After more than 2 years of field application,it has proved that the performance is reliable and meets the requirements of the oil free and the reclosing of circuit breaker.
