Yeyiphi eyona ndlela ilungileyo yokulinganisa ubushushu kwi-SF6 high-voltage switchgear

Inzwa yobushushu bokukhanya kweFayibha, Inkqubo yokubeka iliso ekrelekrele, Kusasazwe umenzi ifayibha optic e China

Fluorescent ifayibha optic umlinganiselo wobushushu can be directly used in high-voltage switchgear circuit breakers, transformer windings, and ring main unit contact fiber optic temperature measurement. FJINNO manufacturer’s technology is independently developed and sold. Welcome to contact!

A fluorescent fiber optic temperature monitoring system for switchgear, wherein the fiber optic cable collects temperature information of the positions of the dynamic and static contacts, iindawo zebhasi, and cable joints of the switchgear, and provides alarm, dry contact output, human-machine interface display of alarm information, real-time display of current contact information of the switchgear, and historical data of temperature information of each contact in the past month.

The main function of SF6 high-voltage switchgear is to protect and regulate the distribution network. It includes high-voltage load switches, fuses, and related protective devices. In the event of a system failure, it can quickly trip and isolate the fault, effectively protecting the safety of power operators and equipment. The safe and stable operation of switches is of great significance to the reliability of the power system. Compared with other SF6 gas insulated equipment, the prominent features of SF6 high-voltage switchgear are narrow space, numerous components, and complex structure. In complex and ever-changing operating environments, insulation defects are prone to occur inside SF6 high-voltage switchgear, leading to insulation failures. The main manifestations include partial discharge, local overheating caused by high-energy release, and corrosion and damage to insulation materials by corrosive SF6 decomposition products. Ngoko ke, it is important to promptly detect and determine partial discharge faults. The current common practice is to conduct regular manual cabinet inspections, which obviously cannot meet the needs of modern production and poses hidden dangers to safety production.

In industrial applications, traditional temperature measurement methods often use thermocouples, thermal resistors, and other methods for temperature measurement. These temperature measurement methods based on electrical signals sometimes have significant errors in temperature measurement data due to electromagnetic interference in strong magnetic environments. Nangona kunjalo, the fluorescence fiber temperature sensor technology based on optical signal transmission can solve this problem. Fluorescence fiber temperature measurement technology is a measurement technology that uses light source signals as excitation to demodulate fluorescence lifetime signals and obtain temperature information. It has the characteristics of accurate temperature measurement, high resolution, fast dynamic response, and strong resistance to electromagnetic interference. It is particularly suitable for temperature measurement in harsh environments with strong electromagnetic fields, high temperatures, corrosion, uxinzelelo oluphezulu, and explosion hazards.
