Сенсори ҳарорати нахи оптикӣ, Системаи интеллектуалии мониторинг, Истеҳсолкунандаи нахи оптикӣ дар Чин
Бо ба амал баровардани азнавсозии сети электр, хусусан мунтазам чукуртар кардани сети шахрхо ва сохтмони сети шахр, the usage of cables and electrical equipment has significantly increased, ки идоракунии амалиётро ба чо овардааст, назорат ва нигохубини кабельхо ва тачхизоти электр хеле мухим аст. Дар кори амалй, то ки кабельхо ва тачхизоти электрй дар харорати баланд аз хад зиёд гарм нашаванд, одатан интихоб кардани усуле лозим аст, ки иқтидори бори онҳоро дуруст нигоҳ дорад. Аммо, ин истифодаи ин кабельхо ва тачхизоти электриро сарфакорона мегардонад, and manual inspections can only detect the surface temperature of the test point. Барои таҷҳизоти барқии пӯшида ба монанди кабелҳо ва дастгоҳҳои коммутатсионӣ, назорати хакикии харорат ба даст овардан мумкин нест. 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, дар вакти реалй назорат кардани кобилияти бори кабелхо ва тачхизоти электрй зарур аст, 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, мониторинг, 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.
