Igikoresho cyo guhindura transformer giciriritse n'igikomeye: Ubuyobozi bwa tekiniki

(Bishyigikiwe n'amakuru n'amabwiriza y'inganda)

Ese?1. Imirimo y'ingenzi n'uruhare rw'ingandaEse?

Switchgear ikora nk'inkingi y'ingufu z'amashanyarazi ziciriritse n'izifite ingufu nyinshi (MV / HV), ikora imirimo itatu y'ingenzi kuri transformers:

• Ese?Gukwirakwiza Ingufu: Itwara amashanyarazi kuva kuri transfomasiyo kugera ku mitwaro binyuze mu byuma bitanga amashanyarazi, utubari tw'imodoka, n'ibikoresho byo kurinda.
• Ese?Uburinzi bw'amakosa: Ihagarika imiyoboro y'amashanyarazi mu masegonda make (urugero, ubushobozi bwo kugabanya umuvuduko wa 31.5kA–40kA) kugira ngo hirindwe kwangirika kw'ibikoresho.
• Ese?Kwishyira mu kato k'umutekano: Igenzura ko ibungabungwa neza binyuze mu gufunga no gufunga ubutaka.

Urugero, sisitemu ya 12kV isaba nibura uburebure bwa 125mm (ifite ubwishingizi bw'umwuka) cyangwa 40mm (ifite ubwishingizi bw'umwuka) kugira ngo hirindwe ko uruziga ruhagarara.

Ese?2. Ubwoko n'igishushanyo mbonera cy'imiterereEse?

Ibyiciro by'ibikoresho byo gusimbuza n'ibisobanuro by'ingenzi:

Ese?Ibice by'ingenzi:

• Ese?Akamashini gakoresha amashanyarazi (VCB): Itanga ibikorwa birenga 10,000 bya mekanike bifite uburinzi bwo gukoraho
• Ese?Amabasi ya bisi: Imashini zikora umuringa cyangwa aluminiyumu (zifite ibice ≥100×10mm²) zifite ubushyuhe buhamye kugeza kuri 40kA/4s.
• Ese?Ibikoresho byo kurinda: Ibikoresho byemewe na IEC 61850 byo gutahura umuriro ukabije, itandukaniro, n'umuraba utukura.

Ese?3. Ibisobanuro bya tekiniki n'amahame ngenderwahoEse?

• Ese?Ingano z'amashanyarazi:

• MV: 3.3kV–36kV (isanzwe mu nganda).
• HV: 66kV–800kV (imiyoboro yo kohereza amakuru).
  • Ese?Urwego rw'ubushyuhe:

• Ese?Ibiranga umutekano:

• Ese?Uburyo butanu bwo kwirinda: Irinda ko ingufu zitangira ku buryo butunguranye (urugero, swichi zo guhagarika umutwaro ntizishobora gufunga keretse ibyuma bigabanya umuvuduko w'amashanyarazi bifunguye).
• Ese?Kugabanya umuvuduko: Ibyuma bidashobora guturika (urugero: 0.8mm aluminiyumu) ​​bifite imyuka ihumeka kuri ≤50kPa kugira ngo birinde ababikora.

Ese?4. Amabwiriza yo guhitamo no kubungabungaEse?

• Ese?Guhitamo Bishingiye kuri Porogaramu:

• Ese?Uduce dufite ikibazo kinini: Koresha GIS ifite SF6-insulated kugira ngo wongere imbaraga za dielectric.
• Ese?Ibidukikije bibi: Hitamo ahantu ho gukingira hafite agaciro ka IP54 hafite irangi ririnda ingese.
  • Ese?Isuzuma risanzwe:
• Ese?Ubudahangarwa bw'aho umuntu ahurira n'abandi: ≤100μΩ (bipimwe hifashishijwe micro-ohmmeter).
• Ese?Ikizamini cya Dielectric: 1.2/50μs imirabyo y'inkuba (± 10% yo kwihanganira).
• Ese?Kuramba mu buryo bwa mekanike: Ibikorwa birenga 5,000 ku byuma bigabanya amashanyarazi.

Ese?5. Ingendo zigenda zizamukaEse?

1. Ese?Guhindura ikoranabuhanga:

• Smart switchgear ihuza sensors za IoT kugira ngo ikurikirane ubushyuhe mu gihe nyacyo, gutigita, no kugenzura igice cy'ibisohoka.
• Urugero: Platform ya Schneider Electric ya EcoStruxure ifasha kubungabunga amakuru ateganyijwe binyuze mu gusesengura ibicu.
  2. Ese?Kuramba:
• Uburyo budafite SF6 (urugero: vacuum cyangwa solid-insulation) bugabanya imyuka ihumanya ikirere ku kigero cya 95%.
  3. Ese?Igishushanyo mbonera cya Moduli:
• Udusanduku two gushyiramo ibikoresho (coup-and-play cabinet) (urugero: UniGear ZS1 ya ABB) bigabanya igihe cyo gushyiraho ibikoresho ho 40%.

Ese?AmareferensiEse?

• IEC 62271-200:Igikoresho cyo gukinga icyuma gipfundikiye gikozwe muri gazi
• IEEE C37.2:Ibipimo ngenderwaho ku mibare y'imikorere y'ibikoresho by'amashanyarazi
• Umuyoboro w'igihugu w'Ubwongereza:Uburyo bwiza bwo kubungabunga ibikoresho byo mu gikoresho
