1. What is Gas Insulated Switchgear Temperature Monitoring

Gas insulated switchgear (GIS) ufuatiliaji wa joto is a continuous measurement system that tracks thermal conditions at critical points within SF6-filled electrical equipment. Teknolojia hii hutambua ongezeko la joto lisilo la kawaida ambalo linaonyesha hitilafu zinazotokea kabla ya kusababisha kuharibika kwa vifaa au kukatika kwa mfumo..

Ufuatiliaji wa halijoto ni muhimu kwa kutegemewa kwa GIS kwa sababu hitilafu za joto kawaida hutangulia hitilafu za umeme.. Overheating inaweza kutokana na kuongezeka upinzani wa kuwasiliana, miunganisho duni ya kondakta, mzigo mkubwa wa sasa, au uharibifu wa insulation. Imeachwa bila kutambuliwa, masharti haya yanaendelea hadi kufikia ukomo, mtengano wa SF6, na uharibifu mkubwa wa vifaa.

Kwa nini Ufuatiliaji wa Joto ni Muhimu kwa GIS

Tabia iliyofungwa ya swichi ya maboksi ya gesi hufanya ukaguzi wa kuona hauwezekani wakati wa operesheni. Tofauti na switchgear isiyopitisha hewa, waendeshaji hawawezi kugundua matatizo ya joto kupitia tafiti za mara kwa mara za infrared. Ufuatiliaji wa kudumu wa halijoto hutoa njia pekee za vitendo za kuendelea kutathmini afya ya joto ya GIS.

Kuongezeka kwa joto huathiri mali ya gesi ya SF6, kupunguza nguvu ya dielectric na kuongeza kasi ya mtengano.

Ufuatiliaji wa joto unaoendelea husaidia kudumisha hali bora za SF6 na kupanua maisha ya huduma ya vifaa.

2. What Causes Temperature Rise in GIS Equipment

Kuelewa sababu za mizizi ya matatizo ya joto huwezesha uwekaji sahihi wa sensor na utambuzi wa makosa ya ufanisi. Vyanzo vya msingi vya Kuongezeka kwa joto la GIS ni pamoja na:

Wasiliana na Ongezeko la Upinzani

Uharibifu wa upinzani wa mawasiliano inawakilisha sababu ya kawaida ya kuongezeka kwa joto kwa GIS. Kuvaa kwa mitambo, oxidation ya uso, na shinikizo la mawasiliano isiyofaa huongeza upinzani wa umeme kwenye pointi za uunganisho. Nguvu iliyosambazwa ni sawa na I²R, ambapo mraba wa sasa huzidisha kwa upinzani, causing exponential temperature rise as resistance increases.

Conductor Connection Issues

Improper torque during installation, thermal cycling fatigue, and mechanical vibration can loosen bolted connections in busbar systems. Even slight gaps at connection interfaces dramatically increase resistance and generate localized hot spots. Aluminum conductor oxidation particularly accelerates this degradation.

Excessive Load Current

Operating GIS beyond rated capacity generates heat throughout current-carrying components. While normally designed with thermal margin, sustained overload combined with elevated ambient temperature can push equipment beyond safe thermal limits. Load current monitoring in conjunction with temperature measurement enables accurate thermal capacity assessment.

Environmental Temperature Impact

Tofauti za halijoto iliyoko huathiri utendaji wa joto wa GIS. Vilele vya majira ya joto hupunguza tofauti ya halijoto inayopatikana kwa uondoaji wa joto, wakati baridi ya baridi inaweza kuathiri wiani wa gesi ya SF6 na mali ya dielectric. Kanuni za fidia ya mazingira huchangia tofauti hizi za msimu katika mifumo ya ufuatiliaji wa joto.

Sehemu hizi za uunganisho huzingatia mtiririko wa sasa na kuwakilisha maeneo yenye hatari ya kupokanzwa yanayohusiana na upinzani. Vitambuzi vya halijoto vinapaswa kusakinishwa kwa pande zote za kila kiungo ili kutambua mifumo ya joto isiyolinganishwa.

Inabadilisha Anwani za Kifaa

Isolator na mawasiliano ya mzunguko wa mzunguko uzoefu wa kuvaa kwa mitambo na mmomonyoko wa umeme wakati wa operesheni ya kawaida. Muundo wa mguso unaosonga kwa asili huunda shinikizo la mguso tofauti na hali ya uso. Vipengele hivi vinahitaji ufuatiliaji nyeti zaidi wa halijoto ili kugundua uharibifu wa mapema.

Viunganisho vya Kiolesura

Haya violesura vya uunganisho benefit from differential temperature monitoring to detect developing problems before they affect system integrity.

4. Jinsi gani Sensorer za Joto la Fiber Optic za Fluorescent Kazi

Upimaji wa joto la optic ya nyuzi za fluorescent exploits the temperature-dependent luminescent properties of rare earth materials. This technology provides inherently safe electrical isolation combined with excellent accuracy and stability for high-voltage applications.

Kanuni ya Uendeshaji

The sensor contains a fluorescent material (typically based on rare earth compounds) positioned at the fiber optic tip. An optical transmitter sends excitation light pulses through the fiber to the sensor probe. The fluorescent material absorbs this light energy and re-emits it at a longer wavelength.

The key measurement parameter is the wakati wa kuoza kwa fluorescence—the time required for the emitted light intensity to decrease after excitation stops. This decay time changes predictably with temperature, decreasing as temperature rises. By precisely measuring the decay time, the system accurately determines probe temperature independent of light intensity, hasara za kupiga nyuzi, au tofauti za kiunganishi.
