Gusobanukirwa Imikorere, Ubwoko, na Porogaramu za Loadbreak Elbow Connectors

Ushobora kumenya buri gicuruzwa gishya gishyirwa ahagaragara hano, kandi ukibonera iterambere ryacu n'udushya dushya.

Gusobanukirwa Imikorere, Ubwoko, na Porogaramu za Loadbreak Elbow Connectors

Itariki: 07-29-2025

Kubera ko duhora dukoresha amashanyarazi yo munsi y’ubutaka, gukenera gukwirakwiza amashanyarazi mu buryo bwizewe, bwizewe kandi bworoshye buri kwiyongera buri munsi. Ibi bisaba gushyiraho uburyo bwo guhuza imiyoboro y’amashanyarazi kugira ngo duhuze kandi dukuremo imiyoboro y’amashanyarazi mu buryo bwizewe.

Izi connectors zihuza insinga zo munsi y'ubutaka n'uduti tw'imbere twapfuye ku byuma bihindura amashanyarazi, bigamije gutuma insinga z'amashanyarazi n'ibikoresho bihindura amashanyarazi bikorana neza kandi byizewe.

None se, ni iki mu by'ukuriUmuhuza w'inkokora ya LoabreakBikora bite?

Reka dusubize ibi bibazo, hamwe n'ibindi byinshi, muri iyi nkuru.

Umuhuza w'inkoni ya Loadbreak ni iki?

Inkokora ya feri yo gushyira imizigo ni icyuma gihuza imizigo gishobora gutandukanywa, gishyirwamo ubushyuhe, gikoreshwa muri sisitemu nyinshi z’amashanyarazi make kugeza kuri hagati mu guhinduranya imizigo hakoreshejwe ingufu. Inkokora zihuza imizigo yo gushyira imizigo zikoreshwa mu guhuza insinga zo munsi y’ubutaka, izikoresha amashanyarazi aciriritse na transfoma, switchgear n’ibindi bikoresho.

Izi connectors zitanga uburyo bwo guhuza ibyuma n'amashanyarazi burinzwe kandi bushobora kwinjizwa mu mazi, kandi zagenewe gukora cyangwa gusenya connections ziri munsi y'umutwaro. Zihabwa amanota menshi kuri sisitemu za 15 kV, 25 kV na 35 kV.

Kugira ngo harebwe ko imitwaro ishobora guhindurwa kandi igakora neza mu gihe cy'imitwaro no mu buryo butandukanye bw'amashanyarazi, inkokora nyinshi zigabanya umutwaro zujuje ibisabwa mu nganda nkaIEEE 386.

Bikora bite?

Imigozi y'umugati ifasha mu guhagarika no kongera guhuza imbonankubone hakoreshejwe ibikoresho bishyushye. Dore bimwe mu bintu by'ingenzi biyiranga:

Igikorwa cyo kugabanya umutwaro/gukora:

Iyi ni yo nshingano yabo y'ingenzi, kuko bashobora guhagarika no guhuza umurongo ugera kuri 200 A, mu gihe bagabanya cyangwa batandukanya ibikoresho bitandukanye kandi badakoresheje imbaraga zose.

Agace k'icyuma gakoreshwa mu gupfunyika icyuma gikozwe mu bumba

Umutwe wa electrode ya keramike urenga igice cy'inkokora kandi ugafasha kuzimya umugozi wakozwe mu gutandukanya umugozi uri munsi y'umutwaro.

Ibikorwa byo gushyushya no gukoresha imashini zishyushya

Abakoresha bashobora gukoresha ibikoresho bishyushya (ibishyimbo bishyushye) kugira ngo bakuremo kandi bashyire inkokora. Aha, uburyo bwo gusohora bukoreshwa mu kugabanya stress y'amashanyarazi no kwangirika, mu gihe bagenzura gutangira kwa arc.

Amanota yo gupima ubushobozi

Uduce two gupima ubushobozi bw'amashanyarazi dushyirwa mu nkokora zo kugabanya umutwaro kugira ngo harebwe niba isano iriho mbere na nyuma yo gucika. Utu duce two gupima ubushobozi bw'amashanyarazi ntabwo dufitanye isano n'umuyoboro mukuru w'amashanyarazi.

Ibi bice byose bikora neza kugira ngo bifashe ko imitwaro igabanya umutwaro guhuza no gukuraho imiyoboro ikora neza mu gihe bibungabunga umutekano w’umukoresha na sisitemu.

Ubwoko bw'ibihuza ibyuma bigabanya umuvuduko w'inkoni

Uduhuza tw’imodoka dukoresha amashanyarazi (load break connectors) turi mu moko atandukanye bitewe n’ubwoko bw’amashanyarazi, imiterere y’ibikoresho n’uburyo bikoreshwa. Reka tuvuge ku bwoko bumwe bukunze gukoreshwa cyane:

Ukurikije icyiciro cy'amashanyarazi:

Inkokora zo gufunga imizigo ziza mu byiciro bitandukanye by'amashanyarazi, bimwe muri byo ni:

15kV:Zagenewe imiyoboro ifite imbaraga zigera kuri kV 15, zifite umuvuduko uhoraho wa Ampere 200. Izi mashini zihuza inkokora za kV 15 zirakingiwe neza, zirimo amazi menshi kandi rimwe na rimwe zifite ibyuma bihuza.

25kV:Ibi Inkokora zo kugabanya umutwaro wa kv 25Bipimirwa kuri sisitemu kugeza kuri 24 kV, akenshi kuri 250 A continuous current hamwe n'ubushobozi bwo gusimbuza 300 A mu masaha 8. Bishyigikira insinga za XLPE cyangwa EPR zishyushye zifite ibice bya conductor kuva kuri ~25–120 mm². Bikoreshwa cyane muri sisitemu zigezweho z'amashanyarazi kandi bitanga uburyo bwizewe kandi bwizewe bwo guhuza/gukuraho insinga nyinshi.

Gusobanukirwa Imikorere, Ubwoko, na Porogaramu za Loadbreak Elbow Connectors

35kV:Nubwo 25Imitwaro yo kugabanya umutwaro wa Kvzikoreshwa kenshi, 35 kV nazo zikoreshwa mu bikorwa bimwe na bimwe byihariye. Zishobora kwihanganira umuvuduko uhoraho wa Ampere 200 n'igipimo cya voltage cyangwa kugeza kuri 35 kV. Kugira ngo zicunge iyi voltage nini, zifite insulation ya EPDM ya peroxide hamwe na semiconducting shield, coupling ya coppertop compression, probe ya copper plated tin ifite arc follower tip, hamwe n'ibipimo by'ibizamini byihariye.

Binyuze mu miterere:

Ibikoresho byo guhagarika imizigo biza mu buryo butandukanye kugira ngo bijyane n'ibikorwa bitandukanye

Inkokora isanzwe yo kugabanya umutwaro:Ibi bikoreshwa mu guhuza insinga imwe n'igikoresho kimwe (urugero: transformer, switchgear). Bikoresha uduce duto tw'icyuma gipima ceramic kugira ngo bishyigikire ibikorwa bikoresha imbaraga.

Inkokora yo mu bwoko bwa "joint":Bitwa kandi imigozi myinshi cyangwa imigozi ya tee. Yemerera amashami binyuze mu guhuza insinga nyinshi hamwe mu nzu imwe ifite ubushyuhe. Imiterere isanzwe irimo imigozi ibiri, 3, n'imigozi ine ikoreshwa mu buryo bugoye bwo gukwirakwiza.

Ifite aho igeragezwa rya capacitive:Izi nkoni zo gufunga imizigo zirimo sensor ikoze mu buryo bwa capacitive kugira ngo yerekane voltage ya circuit (ubusanzwe iri hagati ya 10–12% by'voltage ya phase-to-ground). Iyi mode ituma habaho kugenzura voltage mu buryo bwizewe hatabayeho gukoresha connector mu buryo butaziguye.

Nta ntambwe yo gupimisha:Ibi birakwiriye gushyirwamo aho igeragezwa ry’amashanyarazi rikorerwa ahandi, izi nkokora ntizishobora gutanga igisubizo cyihuse cy’amashanyarazi aturuka ku butaka.

Bitewe n'ahantu hakoreshwa:

Nubwo inkokora nyinshi zigabanya umutwaro ziba zifite imiterere ishobora kwinjizwa mu mazi, zimwe ziba zifite imiterere idapfa kwangirika.

Imiterere y'ibintu bishobora kubohoka mu mazi

Ibi bishushanyo mbonera bishobora gukora neza munsi y'amazi cyangwa mu butaka bwuzuye iyo bihujwe neza n'uduti cyangwa udupfundikizo bihuye. Urugero, Anhuang'sInkokora zo kugabanya umutwaro wa 25 kVbitanga uburyo bwo guhuza bushobora kwinjizwa mu mazi kandi bushobora gutandukana.

Imiterere idapfa kwangirika

Imigozi imwe n'imwe ikoreshwa mu bice byangiza, nko mu turere two ku nkombe cyangwa mu nganda zikora imiti. Itanga uburyo bwo gutandukanya ibintu byangiritse kandi bishobora gucukurwa mu mazi hamwe n'ibikoresho by'icyuma kitagira umugese n'ibice bya EPDM byagenewe kurwanya kwangirika kw'ibidukikije mu bihe bikomeye.

Imikoreshereze isanzwe y'ibihuza inkoko zo mu kiganza bigabanya umutwaro

Dore zimwe mu ngero z'ikoreshwa ry'inkokora zo kugabanya umutwaro mu buzima busanzwe:

Gukwirakwiza ingufu z'amashanyarazi munsi y'ubutaka

Inkokora zo kugabanya umutwaro zikoreshwa cyane mu guhuza insinga zo munsi y'ubutaka zikoresha voltage iciriritse na transformers, switchgear, n'ibindi bikoresho nta guhagarika serivisi.

Transformers n'ibikoresho byo gusimbuza bishyirwa kuri pad

Bituma habaho imikorere myiza kandi itekanye mu gihe cyo guhuza cyangwa gukuramo ibikoresho kuri sisitemu zikora nka transformers zishyirwa kuri pad na switchgear.

Ibikoresho by'inganda, iby'imirimo n'ubucuruzi

Inkokora zo kugabanya umutwaro zikoreshwa ku dusanduku tw’amashanyarazi, ku nganda, no ku nyubako z’ubucuruzi aho gutandukanya no guhinduranya umutwaro mu buryo bw’ingufu ari ngombwa.

Ubuhinzi bw'ingufu zikomoka ku muyaga, imirasire y'izuba n'ingufu zishobora kongera gukoreshwa

Ibi ni byiza cyane mu gushyiraho ibikoresho bishobora kongera gukoreshwa (nk'imirima y'umuyaga n'iy'izuba) aho ibikorwa byoroshye kandi bihoraho bifasha kugabanya igihe cyo kudakora neza mu gihe cyo kubungabunga.

Sisitemu z'ubucukuzi bw'amabuye y'agaciro na gari ya moshi

Ikoreshwa mu turere dukomeye nko mu bucukuzi bw'amabuye y'agaciro no mu buryo bw'amashanyarazi bwa gari ya moshi cyangwa metro kugira ngo igumane ingufu zihoraho mu gihe itandukanya ibice by'amashanyarazi kugira ngo bikoreshwe.

Umwanzuro

Udukoresho two gufunga inkokora ni ngombwa cyane iyo ushaka gutandukanya ibice bimwe na bimwe by'amashanyarazi yo munsi y'ubutaka afite amashanyarazi aciriritse. Bitanga uburyo bwizewe kandi bwizewe bwo gusana ibice bimwe na bimwe by'amashanyarazi nta guhungabanya amashanyarazi muri rusange.

Niba ushaka kuguraIbikoresho byo gushyiramo imbaraga za kV 25ku busabe bwawe, ugomba kureba ubwoko bwa Anhuanginkokora zo kugabanya umutwaro.
