摘要：高壓開關(guān)柜在運行過程中，柜內(nèi)觸點與母線連接處、動靜觸頭電路發(fā)熱過大，易引發(fā)停電和火災(zāi)事故。因此，高壓開關(guān)柜內(nèi)溫度監(jiān)測尤其是三相觸點溫度監(jiān)測非常重要。高壓設(shè)備存在裸露電壓，傳統(tǒng)的有線溫度檢測方法因無法解決高壓絕緣問題而不能應(yīng)用。無線測溫系統(tǒng)采用無線電波進(jìn)行信息傳輸，不需要布線，與高壓設(shè)備等電勢，不需要采取絕緣措施。因而無線測溫系統(tǒng)可解決高壓設(shè)備測溫難題。

Abstract: During the operation of the high-voltage switchgears, The contact in the cabinet and the bus connection, the dynamic and static contact circuit generates too heat, which is easy to cause power failure and fire accident. Therefore, the temperature monitoring is very important in the high-voltage switch cabinet, especially the three-phase contact temperature monitoring. The traditional wired temperature measurement method can not be used because of the exposed voltage of high voltage equipment. The wireless temperature measurement system uses radio waves, no wiring, equal potential with high-voltage equipment, and no insulation measures. Therefore, the wireless temperature measurement system can solve the temperature measurement problem of high-voltage equipment.
