Gishirwata na Zama-zama ta Farkon Kula 10kV a GIS Cubicles: Yadda Ake Taimaka wa Masu Amfani da Ikkila ta Kirkiro Tsarin Kuliya

1 Bincike na Muhimmanci

Aiki na abinci - oksidi da ke fitowa a cibiyoyi, suna da damar karamin jirgin magana na system daga lokacin gaba, wanda yake iya ba da hankali ko kuma kawo shiga gida, hatta kafin ya kashe da karamin jirgin magana. Saboda haka, ana bukata da bincike/maintenance mai girma. Ingantaccen bincike na tsarin shekaru 3-5 (wanda ake rage power, ake fuskantar arrester don test; idan an tabbatar da zama, ake saukar) yana da alamun al'amuran kai da kuma matsaloli na space/environment - based standard - grasping.

2 Siffarwar Ingantaccen Binciken 10kV GIS Cabinet Surge Arrester

Don in taimakawa dalilin cin kofin rai, inganta bincike na zarra-zarra na 10kV GIS cabinet arrester, kula karfin dimagana, da kuma kula fuskantar mafi karfi, ya danganta da gwadon gwamnatin siffarwar ingantaccen bincike.

A cikin amfani da GIS cabinet na musamman, arresters suka fi siffar masu wahala; a lokacin da aka yi grounding faults, suke fitowa energy da kuma siffar sarrafa zuwa siffar masu wahala don kauna ground current. A cikin halin yadda, leakage current (mili-ampere manya, ~10mA resistive component) yana da yawan kadan. Lokacin da akwai kawo shiga ko kuma karamin jirgin magana, resistive leakage current yake zama, amma muhimmanci kamar yadda yake yasa, ba sa bi da yawan kadan, saboda haka tana haifar da kula samun bincike na zarra-zarra da kuma kula taimakawa dalilin cin kofin rai. Saboda haka, ana bukata da kula bayyana resistive current da kuma sadarwa (compensation, total leakage current, third-harmonic).

Don in taimakawa dalilin cin kofin rai, ana bukata da gwadon gwamnati na leakage-current-monitoring comprehensive unit (siffarwar a Figure 1). Yana bincika arresters na musamman online, tare da parametolin kamar leakage current. Idan an rage, yana fara, yana kula check sensors, yana kula kammala errors, da kuma yana kula upload data zuwa servers ta hanyar 5G don remote monitoring.

3 Amfani Da Siffarwar Ingantaccen Binciken Surge Arresters A Cikin GIS Cubicles Na 10kV Substations

Na biyuwar siffarwar ingantaccen bincike, an kawo gwamnati da kuma amfani da shi. Har daidai na online surge arrester monitoring subsystem na nufin data zuwa system na substation na musamman. Yana iya kolektoci parametolin kamar adadin arrester operations, leakage current, operation timestamps (zama zuwa second), da kuma peak discharge current a lokacin da amfani.

Surge arresters sun amfani da through-core zero-flux leakage current sensors don in tabbatar da total current signals. Wannan signals suna zama Fast Fourier Transform (FFT) - wani tushen da ya kula kammala computational complexity da kuma yana iya kula kammala Fourier transforms da kuma kammalar da suka kammala, saboda haka yana zama tushen da ake bukata a cikin power systems. FFT yana bude current signals don in samun harmonic components da kuma kula bayyana frequency-based harmonics.

GIS a cikin 10kV substations yana da hankali mai yawa da third-harmonic pollution, wanda yake iya kula zama system losses, kula zama loads, da kuma kula haifar da binciken arrester - wanda yake iya kula taimakawa dalilin cin kofin rai. Saboda haka, an amfani da third-harmonic method: kula bayyana "third-harmonic" data (three times the 50Hz fundamental frequency) da ake bude ta hanyar FFT. Integrated monitoring unit yana kula connect zuwa arrester sensors ta hanyar RS485 interfaces, yana iya kula collect data daga up to 32 switchgear arresters.

3.1 Data Transmission Da Smart Analysis

Integrated monitoring unit yana amfani da 5G communication module don in kula send detection data zuwa cloud platform. Platform yana kula analyze arrester operation statuses, yana kula trigger alarms for anomalies, da kuma yana kula upload data periodically. Automated data analysis yana kula generate recommendations - e.g., timely arrester replacement or lifecycle predictions. Acquisition system yana taimakawa scheduled data uploads da kuma active uploads during anomalies (as shown in Figure 2).

3.2 System Operation Da Management

Bayan amfani, unit yana kula process total current, third-harmonic, da kuma operation data don in calculate total current, resistive current, da kuma operation info - yana kula send zuwa cloud via 5G. Cloud platform yana nuna arrester lifecycle curves da kuma action alarms, yana taimakawa real-time lifecycle da operation monitoring. Substation backend software yana kula store all detection data, da configurable daily upload frequencies/timings. Idan leakage current yana kafa 10% of the baseline, system yana kula trigger alarms.

Key technical parameters yana kula set as in Table 1. Monitoring system an kawo gwamnati da operational, da debugging aligned to equipment maintenance schedules. Yana kula achieve arrester lifecycle management, real-time monitoring, da kuma improved maintenance efficiency - elevating power system management standards.

4 Kammalawa

Real-time monitoring system for the operating status of surge arresters in GIS cubicles of 10kV substations yana kula send collected data zuwa backend monitoring system via 5G wireless transmission. Bayan haka, a cikin backend monitoring system, yana kula generate curves of arrester lifespan changes da kuma alarm notifications for arrester operations, yana taimakawa real-time grasp of arrester lifespan conditions da operation statuses.

Gwadon gwamnati da amfani da wannan system yana kula enhance the accuracy of operation monitoring for surge arresters in GIS cubicles of 10kV substations, reduce maintenance costs, da kuma prevent major accidents. Kuma yana kula improve the power security for the operation of high-speed railways.
