ለኃይል መሳሪያዎች የፍሎረሰንት ፋይበር ኦፕቲክ የሙቀት መለኪያ መሳሪያ

የፋይበር ኦፕቲክ ሙቀት ዳሳሽ, ብልህ የክትትል ስርዓት, በቻይና ውስጥ የተከፋፈለ የፋይበር ኦፕቲክ አምራች

ከኃይል ፍርግርግ እድሳት ትግበራ ጋር, በተለይም የከተማ ኔትወርክ እድሳት እና ግንባታ ቀጣይነት ያለው ጥልቅነት, the usage of cables and electrical equipment has significantly increased, ኦፕሬሽን አስተዳደር ያደረገው, የኬብል እና የኤሌክትሪክ መሳሪያዎች ቁጥጥር እና ጥገና በጣም አስፈላጊ ነው. በተግባራዊ ሥራ, በከፍተኛ ሙቀት ውስጥ ገመዶችን እና የኤሌክትሪክ መሳሪያዎችን ከመጠን በላይ ማሞቅን ለማስወገድ, ብዙውን ጊዜ የመጫን አቅማቸውን በትክክል የሚጠብቅ ዘዴን መምረጥ ያስፈልጋል. ቢሆንም, ይህም የእነዚህን ኬብሎች እና የኤሌክትሪክ መሳሪያዎች አጠቃቀም ኢኮኖሚያዊ ያደርገዋል, and manual inspections can only detect the surface temperature of the test point. ለታሸጉ የኤሌክትሪክ መሳሪያዎች እንደ ኬብሎች እና መቀየሪያ መሳሪያዎች, ትክክለኛ የሙቀት ቁጥጥር ሊደረግ አይችልም. 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, የኬብል እና የኤሌክትሪክ ዕቃዎችን የመጫን አቅም በእውነተኛ ጊዜ መከታተል ያስፈልጋል, 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.
