Maimaito da Amfani da Maimaito na Tsakiyar Karamin Rike na Zafiya: Muhimman Matafi, Amfani, da Muhimmanci

Saboda darajinsa na rike da zafiya, maimaito na tsakiyar karamin rike na zafiya suna da fara da yawa da dama cewa mai tsarki da suka. A kan wannan farar da yawa, tattalin magana mai tsayi (TMF) ya fi shahara da tattalin magana mai ci (AMF) don gudanar da amfani da karamin rike mai yawa. Idan an gudanar da amfani da karamin rike masu yawa, tsakiyar zafiya yana haifi don koyar da yanayi mai yawa, inda adadin koyar da yanayi ya fi shahara da yanki mai yawa da zafiya.

Idan ba a yi kontrola daidai, wurare masu yawa a fadada tsakiya suna da shiga waɗannan koyar da yanayi mai yawa, wanda yake iya haifar da gano mai yawa ga tsakiyar zafiya a lokacin da amfani da karamin rike ta samu zero, wanda yake iya haifar da gudanar da amfani da karamin rike ta gane. Tattaunawa da tattalin magana mai tsayi—mai tsayi zuwa tsakiyar zafiya—wanda a yi a kan maimaito na tsakiyar zafiya yana haifar da tsakiyar zafiya ta dole a fadada tsakiya. Wannan yana haifar da adadin koyar da yanayi mai yawa, ta bude gano mai yawa a lokacin da amfani da karamin rike ta samu zero, kuma ta bude gudanar da amfani da karamin rike da maimaito.

Muhimman Matafi na Maimaito na Tsakiyar Karamin Rike:

• Tsakiyoyi ba sa tabbataccen ingantaccen

• Yawan ranar da ake amfani da ita, da jiki na amfani da karamin rike ya danganta da jiki na mekaniki

• Maimaito na tsakiyar karamin rike na zafiya zai iya a duba a duk hanyar

• Amfani da karamin rike na zafiya

• Babu sakamakon da za a iya haifar da hoton da kuma babbar wasan da zai iya haifar da hoton; tsakiyar zafiya ana gudanar da shi a kan tsakiyar zafiya mai sarrafa, wanda yake ya shahara da amfani da ita a wuraren da ke da hoton da kuma babbar wasan, misali a wurare da kasuwanci

• Gudanar da amfani da karamin rike ba sa tabbataccen da al'adun da ke faruwa, kamar hawa, kasa, tsakiya, salt fog, ko daraja

• Zai iya gudanar da amfani da karamin rike mai yawa a kan fara da yawa da zafiya

• Gudanar da amfani da karamin rike ta samu lokacin da amfani da karamin rike ta samu zero

• Daidaita da za a iya haifar da shi da kuma daidaita da za a iya gudanar da amfani da ita

Maimaito na tsakiyar karamin rike na zafiya suna da muhimman matafi, amfani da karamin rike, da kuma muhimman tattalin magana sama da maimaito na tsakiyar karamin rike na hawa (ACBs). Amma, suna da muhimman matafi, sama da jiki na amfani da karamin rike da jiki na mekaniki, adadin gudanar da amfani da karamin rike da yawa, da kuma muhimman gudanar da amfani da karamin rike, da kuma "zero arc flash" performance.

Wannan muhimman matafi suna haifar da amfani da ita a wurare da yawa, kamar AC690V da 1140V a TN, TT, da IT configurations—da ake samu a amfani da photovoltaic da wind power. Suna haifar da amfani da karamin rike mai yawa da zafiya. Duk amfani da karamin rike, maimaito na ita suna haifar da amfani da karamin rike da motoci (da ake bayyana da GB50055) da kuma generators (da ake bayyana da GB755), wanda yake ya haifar da amfani da karamin rike da zafiya da amfani da karamin rike da zafiya.

Me Da Ba Iya Amfani Da Maimaito Na Tsakiyar Karamin Rike Na Zafiya Da Yawa?

Dalilin da ya fi shahara shine abin da ya fi shahara da energy:

Maimaito na tsakiyar karamin rike na zafiya suna da abin da ya fi shahara da energy. Saboda farar da yawa, gudanar da amfani da karamin rike ya fi shahara da energy. Don samun abin da ya fi shahara da electromagnetic forces, abin da ya fi shahara da contact pressure ya fi shahara. Misali:

• 31.5kA vacuum breaker ya fi shahara da contact force ta 3200N.

• Don samun abin da ya fi shahara da contact wear, ya fi shahara da contact travel ta 4mm.

• Sannan, abin da ya fi shahara da energy ta fiye da contact engagement zuwa full closure ya fi shahara da energy ta fiye da air circuit breakers.

Abin da ya fi shahara da energy:

• 45 joules for a 40kA breaker (contact force: 4200N)

• 63 joules for a 50kA breaker (contact force: 6200N)

Sannan, operating mechanism ya fi shahara da abin da ya fi shahara da energy. Don amfani da 100kA low-voltage, energy da ya fi shahara da vacuum interrupter ya fi shahara da energy ta fiye da standard low-voltage operating mechanisms.

A yi complete upgrade—larger energy storage springs, increased spring compression stroke, etc. Some existing mechanisms have minimal compression (e.g., only 25mm), and even increasing spring stiffness cannot deliver sufficient energy. Instead, mechanisms with longer stroke are required. As seen in medium-voltage vacuum breakers, cam-driven springs often extend over 50mm, enabling sufficient energy storage. Additionally, the overall mechanical strength, hardness, and rigidity of the operating mechanism must be enhanced to handle the high forces involved.
