摘要：高壓開關設備是變電站和配電站中保證電力系統(tǒng)良好運行的重要設備之一,因此,開關柜的穩(wěn)定運行對于整個電力系統(tǒng)有非常重要的意義。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(fā)生火災，因此,對變電站內的設備進行溫度檢測變得尤為重要。

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.
