Idivayisi yokulinganisa izinga lokushisa kwe-Fluorescent fibre optic yemishini yamandla

Inzwa ye-fiber optic lokushisa, Uhlelo lokuqapha oluhlakaniphile, Umkhiqizi we-fiber optic osabalalisiwe e-China

Ngokuqaliswa kokulungiswa kwegridi yamandla, ikakhulukazi ukujula okuqhubekayo kokulungiswa nokwakhiwa kwenethiwekhi yasemadolobheni, the usage of cables and electrical equipment has significantly increased, okwenze ukuphathwa komsebenzi, ukuqapha kanye nokugcinwa kwezintambo kanye nempahla kagesi kubaluleke kakhulu. Emsebenzini ongokoqobo, ukuze ugweme izintambo nemishini kagesi ekushiseni ngokweqile emazingeni okushisa aphezulu, ngokuvamile kuyadingeka ukukhetha indlela egcina ngokufanelekile umthamo wabo womthwalo. Nokho, lokhu kwenza ukusetshenziswa kwalezi zintambo kanye nempahla kagesi kungabi namali, and manual inspections can only detect the surface temperature of the test point. Okokusebenza kukagesi okuvalekile njengamakhebuli nama-switchgear, ukuqapha kwangempela kwezinga lokushisa akukwazi ukufezwa. 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, ukuqapha ngesikhathi sangempela umthamo womthwalo wezintambo kanye nempahla kagesi kuyadingeka, 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.
