Karamin Hanyarci na Farko (don Siikolin da Dama 3-35 kV)

A cikin jikohin kula da sauran 3-35 kV na Najeriya, yawan waniyan na tattalin kula suna yi aiki a matsayin mafi tsanani. Suna da rike a yi aiki zuwa 2 awa daga lokacin da zaka iya samun hankali mai sauƙi, wanda yana taimakawa a kan ci gaba da aiki da kuma yin abin da shi a kula. Amma, idan yanayin aiki ya zama mafi yawa da kuma zane da kula ta kawo karshen zabe, an yi tasiri mai yawa a kan system-to-ground capacitive current.
Idan hankali mai sauƙi na waniyan yanzu ne, yawan capacitive current mai yawa yana ba da shi da hankali ba su iya kawo karshen, wanda zai iya canzawa a kan hankali mai sauƙi da kuma hankali mai sauƙi mai yawan. Wannan hankali mai sauƙi da kuma ferroresonance overvoltage suna da muhimmanci a kan cin hankali ga tsafta. Daga cikinsu, hankali mai sauƙi na waniyan yana da muhimmanci - masu aiki babba suka iya haɗa zuwa 3-3.5 marubucin mutum. Aiki da ma'ana da wannan adadin lokacin har zuwa lalacewa da shi a kula, kuma a yi nasarar da kula ta kawo karshen, hankali mai sauƙi, kuliya da shi a kula, kula da shi a kawo karshen, PT da shi a kula da kuma hankali mai sauƙi.

Ta hanyar zaman lafiya, ana fito arc suppression coils a kan tattalin kula don in taimaka a kan in taimaka da capacitive current da kuma in kawo karshen tsanani. Amma saboda haddasan da ke cikin arc suppression coils - musamman abin da suke da shi a kan in taimaka da capacitive current (wato abin da ke da shi a kan tsanani) - bayanin da aka yi bai zama daidai ba.
Don haka, duk da cikakken fahimtar da aka yi a kan arc suppression coils, muna kafa RMRXHG Intelligent Arc Suppression Device, wanda ya kamata a kan in taimaka da long-duration overvoltage da ke cikin hankali mai sauƙi, tare da taimakawa mai yawa da kuma taimakawa a kan in kawo karshen masu aiki da kula mai tsanani.

Ingantaccen Fadada

• Yana da amfani a kan jikohin kula da sauran 3-35 kV.
• Yana da amfani a kan tattalin kula da sauran, tattalin kula mai tsanani (ta hanyar arc suppression coil), da kuma tattalin kula mai tsanani mai yawa.
• Yana da amfani a kan tsafta da ke da kula, tsafta mai kula da kuma kara, ko kuma tsafta mai kara da kula.

Fadada Masu Aiki

• A lokacin da aiki, wani ya taimaka a kan PT signals, da kuma ya taimaka a kan alarm, trip, da kuma lockout functions. Yana da amfani a kan in taimaka da hankali mai sauƙi na waniyan, in taimaka da wurin hankali, in kawo karshen, in kawo karshen harmonics, in taimaka da hankali mai sauƙi, da kuma in taimaka da record.
• Yana taimaka a kan in taimaka da parametars kamar lokacin hankali, nau'in hankali, hankali mai sauƙi, line voltage, da kuma neutral current, tare da taimakawa a kan in taimaka da analysis hankali.
• Idan hankali mai sauƙi na waniyan yanzu ne, wani ya taimaka a kan in taimaka a kan lokaci 30 ms, in taimaka da nau'in hankali, da kuma in taimaka da arc suppression measures (arc suppression coil, grounding resistance, ko kuma wasu hanyoyi).
• Yana taimaka a kan in kawo karshen hankali mai sauƙi, tare da taimakawa a kan in kawo karshen tsanani da kula, hankali, ko kuma kula da shi a kawo karshen.
• Yana taimaka a kan in taimaka da PT disconnection monitoring, tare da taimakawa a kan in kawo karshen tsanani da ke cikin PT failures.
• Yana da PTK smart switching technology, wanda yana taimaka a kan in kawo karshen hankali mai sauƙi da ke cikin hankali mai sauƙi, tare da taimakawa a kan in taimaka da kula da shi a kawo karshen.
• Yana da amfani a kan RS-485 communication da MODBUS protocol don data acquisition da kuma remote monitoring.

Fadada Mafi Tsanani

• Yana da amfani a kan automatic neutral selection circuit.
• Yana taimaka a kan RMRXL low-current grounding selection device don in taimaka da accuracy da ke cikin detection hankali.
• Yana da amfani a kan “elimination” mode: wani ya taimaka a kan in kawo karshen residual charge da kuma in kawo karshen ferroresonance damage to PTs.
• Yana da amfani a kan user-customizable additional harmonic suppression modules.

Principle na Aiki

• Controller ya taimaka a kan in taimaka da secondary voltages of PTs a open-delta connection.
• Idan hankali mai sauƙi na waniyan yanzu ne, yana taimaka a kan in taimaka da changes in PT secondary voltages (Ua, Ub, Uc) don in taimaka da nau'in hankali.
• Idan hankali mai sauƙi na metallic yanzu ne, wani ya taimaka a kan in taimaka da fault point, in taimaka da trip signals, da kuma in taimaka da kula da shi a kawo karshen.
• Idan hankali mai sauƙi na intermittent arc-ground yanzu ne, system ya taimaka a kan in taimaka da fault characteristics da kuma in taimaka da suppression unit a lokacin 30-40 ms, tare da taimakawa a kan in kawo karshen escalation hankali mai sauƙi.
• Idan tattalin kula mai tsanani, wani ya taimaka a kan in kawo karshen transient da steady-state overvoltages, tare da taimakawa a kan in taimaka da safe system recovery.
