Tahallufin Vibration Signal don Jin Dadin Circuit Breaker (CB)

Bayani

A cikin tsari na buɗa da karama ta circuit breaker (CB), an samu siffar vibration. Wannan siffar ya ƙunshi bayanan muhimmanci game da kyakkyawan dadin zarurin, tare da lokacin da mazauna na arc ya faru, wanda zai nuna abin da lafiya ko masana'antu masu nasara ko wasu batun da suka shafi. Wata muhimmiyar baka na jin dadin CB shine ci gaba daga karamin switchgear contacts, wanda yana nufin tsaya kadan da mazaunan arcing ya yi waɗansu a kan karamin kowane lokaci.

Ci Gaba Daga Karamin Switchgear Contacts

Mazaunan arcing na CB suna ƙoƙarin kadan ne saboda ablation a kan karamin kowane lokaci. Wannan yanayi ya haɓaka tsakiyar lokacin da mazaunan arcing ya sauya, wanda za a iya jin da ta hanyar siffar vibration. Rukunin da aka ba shi shine ci gaba daga siffar vibration daga gwamna na CB ta hanyar accelerometer. An samun bayanin da za a iya amfani da ita a biyu na wurare:

1. Kwamfwatar Pattern-Pattern da Siffar Tushen:

• Yadda Ake Kwamta Faraskiya: Ta hanyar kwamfa pattern-pattern da aka samu da siffar tushen (wani yanayi da a san CB a cikin halin da ake da lafiya), ana iya kwamta faraskiya daga biyu. Wannan kwamfa zai taimaka wajen bincike irin alamar yaduwar CB a lokacin, kamar yadda dalilin lokacin da mazaunan ya sauya ya ƙara saboda ablation.

• Kwamfa Ta Hanyar Tsakiya: An zama da iya ɗaukan tsakiya don hawarar la'akari idan faraskiyar tsohon ya fi yawa, wanda yana nuna cewa mazaunan suna ƙoƙarin kadan da ke da kyau da ke da lafiya ko kuɗi da ke so in ake gudanar da su.

2. Jin Loci na Lokaci:

• Jin Loci na Lokaci: Ta hanyar jin locin lokaci daga fannoni na biyu a kan siffar vibration (kamar lokacin da mazaunan ya sauya da karama), ana iya bincike irin alamar yaduwar mekaniki na CB. Misali, idan mazaunan suna ƙoƙarin kadan, lokacin da ake faru a kan lokacin da ake buɗe karama da lokacin da mazaunan ya sauya zai ƙara, wanda yana nuna ablation na ƙoƙarin kadan.

Jin Batun Mekaniki

Tahallufin siffar vibration zai iya amfani da ita don jin batun mekaniki a kan CB. Wata hali mai zurfi shine amfani da Dynamic Time Warping (DTW), wata yanayi wanda ke tsara data-data na tsari, hatta idan ban da ƙarin tsari. DTW yana da muhimmanci wajen bincike farashe-farashe a kan pattern-pattern na vibration wanda ke nuna batun mekaniki, kamar karkashin hali, kungiyoyi, ko abin da lafiya a kan abubuwa masu karfi.

Rukunuka don Amfani da DTW a Tahallufin Vibration na CB:

1. Samun Bayanai:

• Saka accelerometers a kan gwamna na CB don samun data-data na vibration a kan lokacin da ake buɗe da karama.

• Samun data-data na vibration tushen daga CB da ake da lafiya don kwamfa.

2. Gargajiya:

• Filter da normalize siffar-siffar na vibration don cire kashi da inganta ma'anarsu a kan ƙarin samun.

• Sakata data-data na vibration zuwa lokutan lokuta na lokaci da ke nuna fannoni na biyu (kamar lokacin da mazaunan ya sauya, lokacin da mazaunan ya sauya).

3. Amfani da Yanayin DTW:

• Amfani da yanayin DTW don kwamfa pattern-pattern na vibration da aka samu da data tushen.

• Kirkiro adadin lokaci (ko yanayi na mutane) daga biyu. Adadin lokaci mai yawa yana nuna ƙarin faraskiya daga halin yaduwar da ake da lafiya.

4. Jin Batun:

• Dauka tsakiyoyi don adadin lokaci na DTW don bincike lokacin da pattern-pattern na vibration ya ƙara saboda faraskiya daga tushen.

• Amfani da wannan tsakiyoyi don ɗaukar batun-batun mekaniki, kamar karkashin hali, abin da lafiya, ko wasu batun.

5. Jin Dadin Daɗi Da Samun Daidaitu:

• Amfani da jin dadin daɗi da samun daidaitu ta hanyar samun data-data na vibration zuwa rana da kuma kwamfan ta da data tushen ta hanyar DTW.

• Samun samun daidaitu don taimaka da jin yaduwar daɗi na CB da kuma bincike trens na ƙoƙarin kadan mekaniki.

Misal: Tahallufin Vibration Ta Hanyar DTW Don High-Voltage (HV) CBs

A cikin graphin da aka bayar, an samu tahallufin vibration ta hanyar DTW don HV CB. Graphin ya ƙunshi:

• X-Axis: Lokaci (ko index na sampili) wanda ya nuna durancin yaduwar CB (buɗa ko karama).

• Y-Axis: Amfani na vibration ko wani yanayi na amfani (kamar acceleration) daga accelerometer.

• Curve na Tushen: Curve mai sauƙi wanda ya nuna pattern-pattern na vibration na CB da ake da lafiya.

• Curve na Test: Curve mai sauƙi wanda ya nuna pattern-pattern na vibration na CB da batun mekaniki da ake shafi.

• Adadin Lokaci na DTW: Danna ko curve wanda ya nuna ma'ana ko faraskiya daga biyu na curve-curve. Adadin lokaci mai yawa na DTW yana nuna ƙarin faraskiya daga halin yaduwar da ake da lafiya.

Ta hanyar jin adadin lokaci na DTW zuwa rana, ana iya bincike irin alamar yaduwar mekaniki na CB, kamar yadda abin da lafiya ya ƙara ko karkashin hali, hatta idan wannan batun-batun suka zama mai mahimmanci.

Kammala

Tahallufin siffar vibration, musamman ta hanyar Dynamic Time Warping (DTW), yana ƙunshi aikace-aikacen taimakawa mai zurfi don jin dadin circuit breakers. Ta hanyar kwamfa pattern-pattern na vibration da data tushen da kuma binciken faraskiyar lokacin da fannoni na biyu, ana iya bincike batun mekaniki, jin ablation na mazaunan, da kuma hada a matsayin batun. Yadda na iya amfani da wannan hali don jin dadin daɗi da samun daidaitu, ana taimaka wajen tabbatar da cewa CBs suna da lafiya da kalmomin da suka taka zuwa rana.
