Jinsi ya kufuatilia hali ya joto ya transfoma ya traction ya wimbo-INNO

Kwa nini transfoma za mvuto katika usafiri wa reli zinahitaji kufuatiliwa

Kwa magari ya reli, transformer ya traction ni mojawapo ya vifaa muhimu zaidi na sehemu ya msingi ya mfumo mzima wa traction ya umeme. Uendeshaji wake wa kawaida una athari kubwa katika kuhakikisha utendakazi thabiti wa magari ya reli kama vile locomotives na treni za mwendo kasi.. Pamoja na ukuaji unaoendelea wa jumla ya maili ya reli ya umeme nchini China, mahitaji ya transfoma traction pia kuongezeka; Wakati huo huo, ongezeko la uzito wa uvutaji wa treni na ongezeko la kasi ya mwendo wa treni husababisha kuongezeka maradufu kwa mkondo wa kuvuta. Kwa sasa, idadi kubwa ya transfoma za kuvuta nchini China hufanya kazi chini ya hali ya upakiaji. Sambamba na mabadiliko makubwa katika mzigo wa traction na mizunguko fupi ya nje ya mara kwa mara, uwezekano wa makosa kutokea umeongezeka sana.

Kwa miaka mingi, matengenezo ya transfoma traction nchini China daima imepitisha mfumo wa matengenezo ya mara kwa mara. Ingawa mpango huu unaweza kugundua shida za kifaa ndani ya muda fulani, wafanyakazi wa matengenezo hawawezi kuchagua vitu maalum vya matengenezo kabla ya kutengeneza vifaa, na kufuata sheria tu. Hii itasababisha upofu katika kazi na kupoteza nguvu kazi nyingi, rasilimali za nyenzo, na rasilimali fedha. Kwa hiyo, ufuatiliaji mtandaoni wa transfoma za traction ni muhimu sana; Tofauti na mpango wa maendeleo wa Gridi ya Serikali kwa vituo mahiri vya nguvu, ufuatiliaji wa mtandaoni wa transfoma za mvuto bado uko katika hatua ya ufuatiliaji wa madaraka. Kiasi cha ufuatiliaji kinalingana na kifaa cha ufuatiliaji, na kila kifaa kinalingana na mfumo, na kila mfumo unajitegemea, bila mwingiliano wowote wa habari na mfumo wa ufuatiliaji wa kompyuta, kutengeneza visiwa vya habari, ambayo hufanya ufuatiliaji wa mtandaoni wa transfoma za traction ya reli kutofanya kazi. Kifaa cha kina cha ufuatiliaji mtandaoni kinahitajika kwa transfoma za mvuto wa reli, ambayo inaweza kufuatilia kwa kina idadi ya data mbalimbali na kuzitambua kwa usawa; Na kifaa kinahitaji kuzingatia hali ya sasa ya vituo vidogo vya reli kuwa mbali na kwa tovuti ndogo..

Mfumo wa kipimo cha joto kwa vilima vya transfoma ya traction

Idadi kubwa ya makosa kulingana na transfoma ya traction ni makosa ya joto. Kwa sasa, the existing electrified railway traction transformers in China only rely on measuring oil temperature to determine internal source conditions, and cannot detect the temperature of transformer windings, cores ya chuma, nk., which is inappropriate. FJINNO utilizes a fluorescent fiber optic winding temperature measurement system to directly measure the winding temperature of traction transformers, thereby truly achieving real-time monitoring of faults in traction transformers.

With the continuous development and progress of power technology, the functional demand for transformers is increasing day by day. With the widespread application of traction transformers, while their performance continues to improve, the requirements for their operating environment are also constantly increasing. As the most important environmental factor, juu ya usahihi na ufanisi wa udhibiti wa joto, zaidi inaweza kuboresha ufanisi wa uendeshaji wa transfoma. The mfumo wa kipimo cha joto cha nyuzi za fluorescent hutumika kupima joto katika sehemu mbalimbali ndani ya kibadilishaji wakati wa operesheni, na inafaa hasa kwa ufuatiliaji wa mabadiliko ya joto ya transformer ya traction wakati wa mabadiliko makubwa ya mzigo na overloading. Kama inavyojulikana, wakati wa joto mara kwa mara wa mafuta ya transfoma ni kiasi kikubwa. Kwa hiyo, mabadiliko katika mzigo yanaweza kusababisha mabadiliko ya joto katika msingi wa vilima na vipengele vingine, ambayo yanahitaji muda mrefu zaidi kuonyeshwa kupitia ongezeko la joto la mafuta. Mabadiliko ya joto ya mafuta hayawezi kutafakari hali ya mzigo wa transformer ya traction katika reli za umeme kwa wakati unaofaa., and abnormal overloading cannot be dealt with in a timely manner.

Advantages of Fluorescent Fiber Optic Temperature Measurement Device for Transformer Windings

The fluorescence fiber optic winding mtawala wa joto utilizes the principle of fluorescence fiber optic temperature measurement and installs a fluorescence fiber optic temperature probe on the transformer winding. Through specific analysis algorithms, the real-time temperature value of the winding can be accurately calculated. It has the advantages of maintenance free, calibration free, na kuegemea juu.

The traction transformer winding temperature measurement system adopts fiber optic sensing technology to measure the actual temperature of the transformer winding in real time, which is faster and more accurate than thermocouple measurement, and more comprehensive than the commonly used thermal imaging method for indirect measurement. The fiber optic temperature measurement system has a long operating life, utendaji thabiti, usahihi wa juu, and durability, and has been widely used. The fluorescent fiber optic sensor probe can withstand the initial manufacturing process of transformers, such as kerosene gas-phase drying, heat flow circulation, as well as long-term oil immersion and vibration, without calibration for long-term use, and is stable and reliable. The system reflects the actual temperature of the three-phase winding of the transformer in real-time during operation and sends out real-time over temperature alarm signals, while achieving the purpose of remote transmission of temperature and alarm signals. Ni muhimu sana kuboresha utendaji wa transfoma na kuboresha maisha salama ya huduma ya transfoma.
