 Application of Acrel Wireless Temperature Products in Nanning Financial Investment Center

摘 要：高壓開關(guan) 設備是變電站和配電站中保證電力係統安全運行的重要設備之一,因此,開關(guan) 櫃的穩定運行對於(yu) 整個(ge) 電力係統有非常重要的意義(yi) 。設備老化、長期高負荷運行都可能使設備局部溫度過高而發生火災，因此,對變電站內(nei) 的敏感設備進行溫度檢測變得尤為(wei) 重要。

關(guan) 鍵詞：高壓開關(guan) 櫃；無線測溫；溫度檢測

Abstract：High-voltage switchgear is one of the important equipment to ensure the safe operation of the power system in substations.Therefore, the stable operation of the switchgear is of great significance to the entire power system. The aging of equipment and long-term high-load operation may cause the local temperature of the equipment to be too high and cause fire.Therefore, temperature detection of sensitive equipment in substations becomes particularly important.
