Fluorescent fiber optic temperature measurement device for power equipment

sénsor suhu serat optik, Sistim ngawaskeun calakan, Produsén serat optik disebarkeun di Cina

Kalayan palaksanaan renovasi jaringan listrik, utamana deepening kontinyu renovasi jaringan kota jeung konstruksi, the usage of cables and electrical equipment has significantly increased, nu geus dijieun manajemén operasi, monitoring sarta perawatan kabel sarta alat-alat listrik pohara penting. Dina karya praktis, Pikeun ngahindarkeun kabel sareng alat-alat listrik tina panas teuing dina suhu anu luhur, éta biasana perlu milih métode nu appropriately preserves kapasitas beban maranéhna. Sanajan kitu, hal ieu ngajadikeun pamakéan kabel ieu sarta alat-alat listrik uneconomic, and manual inspections can only detect the surface temperature of the test point. Pikeun parabot listrik enclosed kayaning kabel sarta switchgear, ngawaskeun suhu leres teu tiasa dihontal. Whether from the perspective of the safe operation of electrical equipment such as cables and ring main cabinets or from the perspective of power system scheduling needs, ngawaskeun sacara real-time kapasitas beban kabel sareng alat listrik diperyogikeun, which can be achieved through online real-time monitoring of the temperature of the test points.

The reliability of high-voltage switchgear under high voltage and high current conditions is closely related to the temperature rise of the isolation switch contacts. During the operation of the power grid, mechanical vibration, contact erosion, and other reasons can worsen contact conditions, increase contact resistance, cause an increase in contact point temperature, exacerbate contact surface oxidation, and lead to local welding or arc discharge at loose contact points, ultimately causing damage to electrical equipment, power outages, or major accidents such as fires. This type of contact overheating fault accident is not only due to the quality problem of the high-voltage cabinet switch itself, but more importantly, due to the lack of effective monitoring methods for the temperature rise of the isolation switch contacts at present.

Regarding the operation of contact temperature in high-voltage switchgear and cable branch boxes, by measuring, monitoring, and statistically analyzing the temperature of branch boxes, switchgear or high-voltage contacts using fluorescent fiber optic contact, operators can comprehensively grasp the working conditions of branch boxes, switchgear or high-voltage contacts, and avoid or reduce the occurrence of faults; The high-voltage power temperature measurement system has good reliability and complete functions.
