摘 要: 為保證變電站檢修人員及時獲取變電站當前運行狀態,設計了一種適用不同變電站通信方式下的事故聲光報警裝置。該裝置由基于MCS-51 系列單片機的控制電路模塊、DC-DC 電源模塊、故障信號采集模塊及聲光報警模塊構成。報警裝置可以通過開關量讀取或者以太網通信經IEC 60870-5-101 或CDT 規約解析出故障信號。該報警裝置已在某220 kV 變電站測試使用,可以可靠反映變電站斷路器狀態,在故障發生時提醒工作人員停止工作并做出故障處理措施。

Abstract: A kind of accident sound and light alarm device, which is suitable for non-substation communication, was designed in order to ensure that the inspectors in transformer station could timely obtain the current running state. The device consisted of a control circuit module based on MCS-51 microcontroller (MCU), DC-DC power module, fault signal acquisition module and sound and signal alarm module. The alarm device could read the fault signal by means of on-off number or parse the fault signal through Ethernet according to the protocol of IEC 60870-5-101 or central data terminal (CDT). The alarm device has been applied in some 220 kV substation, and could reliably reflect the state of transformer breaker and remind the staff to stop working and to make
troubleshooting measurement.
Key words: alarm device; substation; IEC 60870-5-101; alarm signal
