Ibisobanuro bigufi:

Hamwe niterambere ryihuse ryumuriro wamashanyarazi nicyaro nicyaro, impinduka nini zabayeho mumashanyarazi, kandi umuyoboro wo gukwirakwiza wiganjemo insinga wagaragaye.Ubushobozi bwubutaka bwiyongereye cyane.Iyo icyiciro kimwe cyubutaka kibaye muri sisitemu, habaho amakosa make kandi make ashobora kugarurwa.Gukoresha uburyo bwo guhangana n’ubutaka ntibuhuza gusa n’iterambere ry’ibanze n’impinduka zisabwa n’umuyoboro w’amashanyarazi mu gihugu cyanjye, ariko kandi bigabanya urwego rw’ibikoresho by’amashanyarazi ku cyiciro kimwe cyangwa bibiri, bikagabanya ishoramari ry’umuriro rusange.Gabanya amakosa, uhagarike resonance irenze urugero, kandi utezimbere umutekano nubwizerwe bwa sisitemu yingufu.

Kugeza ubu, uburyo butagira aho bubogamiye bushingiye ku kurwanya bwanditswe mu mabwiriza y’inganda.Inganda zingufu zamashanyarazi DL / T620-1997 "Kurinda ingufu zirenze urugero no guhuza ibikorwa by’amashanyarazi ya AC" biteganijwe mu ngingo ya 3.1.4: "5 ~ 35KV igizwe ahanini na sisitemu yo gukwirakwiza amashanyarazi no gukwirakwiza igizwe n'imirongo y'insinga, iyo imwe -ikosa ryubutaka rifite ubushobozi bunini bwa capacitive, uburyo bwo guhangana nubutaka buke burashobora gukoreshwa, ariko ibisabwa byokwizerwa byogutanga amashanyarazi, ingaruka zumuvuduko wigihe gito numuyoboro wigihe gito kubikoresho byamashanyarazi mugihe cyamakosa, hamwe ningaruka kubitumanaho Ibisabwa tekiniki yo gukingira n'uburambe mu bikorwa byaho, n'ibindi. ”Ingingo ya 3.1.5 iteganya ko: "Sisitemu yo gukwirakwiza amashanyarazi 5KV na 10KV hamwe na sisitemu y’amashanyarazi, iyo amashanyarazi ya faza imwe yubutaka ari ntoya, kugirango hirindwe Harm kubikoresho nka resonance, icyuho, I arc hasi ya volvoltage, nibindi. ., irashobora gushingirwaho no guhangana cyane. ”

Kubishushanyo mbonera no gutoranya akabati kirwanya, nyamuneka reba kuri: DL / 780-2001 Sisitemu yo gukwirakwiza Sisitemu itabogamye ya Resistor Neutral Grounding Method nuburyo bukubiyemo urwego rwo kubika imirongo n'ibikoresho, kwivanga mu itumanaho, kurinda imiyoboro no kurinda amashanyarazi Kubera ikibazo cyuzuye cyo kwizerwa nibindi bintu, sisitemu yo gutanga amashanyarazi y'urusobe rwigihugu rwanjye rwo gukwirakwiza hamwe ninganda nini n’inganda n’amabuye y'agaciro biratandukanye.Mubihe byashize, benshi muribo bakoreshaga uburyo bwo gukora bwa neutre idafite aho ibogamiye kandi igashingirwaho na co guhagarika coil.Mu myaka yashize, kubera iterambere rya sisitemu y’amashanyarazi no kwiyongera kw’abakoresha amashanyarazi, amashanyarazi amwe n'amwe yo mu ntara n’amakomine yazamuye ingufu mu buryo bwo guhangana n’ubutaka.
