Fluorescent fiber optic temperature measurement device for power equipment

Sensor ng temperatura ng fiber optic, Intelligent na sistema ng pagsubaybay, Ibinahagi ang fiber optic na tagagawa sa China

Sa pagpapatupad ng power grid renovation, lalo na ang patuloy na pagpapalalim ng urban network renovation at construction, the usage of cables and electrical equipment has significantly increased, na ginawa ang pamamahala ng operasyon, ang pagsubaybay at pagpapanatili ng mga kable at kagamitang elektrikal ay napakahalaga. Sa praktikal na gawain, para maiwasan ang pag-init ng mga cable at electrical equipment sa mataas na temperatura, karaniwang kinakailangan na pumili ng isang paraan na naaangkop na nagpapanatili ng kanilang kapasidad sa pagkarga. Gayunpaman, ginagawa nitong hindi matipid ang paggamit ng mga kable at kagamitang elektrikal, and manual inspections can only detect the surface temperature of the test point. Para sa mga nakapaloob na kagamitang elektrikal tulad ng mga cable at switchgear, hindi makakamit ang tunay na pagsubaybay sa temperatura. 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, Ang real-time na pagsubaybay sa kapasidad ng pagkarga ng mga kable at kagamitang elektrikal ay kinakailangan, 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.
