15kV/1250A MV outdoor vacuum Auto Circuit recloser

Deskripsyon:

Siri RCW ti automatik circuit reclosers yana da zama a yi amfani da shi a wurare na kashi tsari da kuma a cikin tushen kashi tsari don duka matsayin voltage 11kV zuwa 38kV a 50/60Hz power system. Da kuma rated current yake ya zama 1250A. Siri RCW ti automatik circuit reclosers yana haɗa aiki a cikin kontrol, gidaje, masu karatu, komunikaci, koyar da kuma online monitoring of closing or opening. Siri RCW ti vacuum recloser yana da muhimmanci a yi amfani da integration terminal, current transformer, permanent magnetic actuator da kuma recloser controller.

Faifai:

• Zaɓe da grades mai zurfi a cikin rated current range.

• Da zaɓe da relay protection da logic don ƙarfafa.

• Da zaɓe da communication protocols da I/O ports don ƙarfafa.

• PC software don testing, setup, programming, da updates ta controller.

Me ke nufin vacuum arc extinguishing fault na outdoor vacuum recloser da abubuwan da za su lura?

Faults na Vacuum Arc Quenching Chamber:

• Gidaje na Level na Vacuum: Wannan shine mafi girma a cikin faults na vacuum arc quenching chambers. Vacuum arc quenching chamber yana iya da level na vacuum mai uku don kiyaye arcs. Idan level na vacuum ya zama, idan insulation performance da kuma arc-quenching ability zai ci gaba sosai. Sabbin da ke yi gidaje na level na vacuum sun hada da sealing mai karfi, kamar aging ko damage na materials, ko kuma leakage wajen sarrafa. Idan level na vacuum ya zama da kyau, ba za a yi kiyaye arc daidai domin faɗa, zai iya faɗa zuwa arc reignition da kuma line faults.

• Koyar na Contacts: A lokacin da zaka samun opening da closing operations, contacts na vacuum arc quenching chamber zai iya koyar saboda arc erosion. Koyar na contacts zai iya zama contact resistance, wanda zai iya haɗa kan severe heating na contacts idan normal current ya barce, zai iya haɗa kan aiki na equipment. Kuma a lokacin da fault current interruption, contacts ba zan iya jin da high current, zai iya faɗa zuwa contact welding ko failure to interrupt the current.

Abubuwan da za su lura Faults na Vacuum Arc Quenching Chamber:

Gidaje na Level na Vacuum:

• Detect Level na Vacuum: Amfani da specialized vacuum level detection instruments, kamar vacuum level testers, don check level na vacuum na vacuum arc quenching chamber. Idan level na vacuum an samu cewa ya zama da kyau, vacuum arc quenching chamber yana da kyau a canzawa.

• Canzawa Seals: Idan kana sance cewa sealing mai karfi yana yi gidaje na level na vacuum, bincika da canza seals. A lokacin canzawa seals, hakuri da kake amfani da high-quality, compatible sealing materials da kuma follow correct installation procedures don ruɗu leakage.

Koyar na Contacts:

• Bincika Regular: Bincika regular wear condition na contacts through observation windows ko by disassembling the device. Based on the degree of wear, if the wear exceeds the specified limit, the contacts should be replaced promptly.

• Optimize Operating Parameters: Analyze the causes of contact wear, such as whether it is due to frequent operations or excessive operating current. If the issue is frequent operation, consider optimizing the recloser's reclosing strategy to reduce unnecessary opening and closing operations. If the issue is excessive operating current, check the line load conditions, adjust the protection settings, and avoid subjecting the contacts to excessive current impacts.
