Ubushobozi bwose bushobora gupimwa (bifise ibihimba bisanzwe) vyerekana inzira ngufi zishobora kubaho.

Igerageza ry’ugukomeza rikoresha abagerageza batanga ibimenyetso vyemewe igihe ubudahangarwa bugabanuka munsi y’agaciro k’imbere- mu buryo bw’ukuri ari ohms nkeyi. Ivyo bituma umuntu ashobora gusuzuma ningoga ubutungane bw’imigozi kandi agafasha gukurikirana ahantu hagufi mu buryo bugoye.

Igerageza ry’ubushobozi bwo guhangana n’umuriro rikoresha umuriro mwinshi (mu bisanzwe 500-1000V) hagati y’ibikoresho vy’amazi n’ubutaka, gupima umuriro w’amazi. Ivyo bikoresho vy’ubuhinga bwa none vyerekana uruja n’uruza rw’amashanyarazi, kumenya imbere y’igihe imirongo miremire y’imbere n’igihe nyene imirongo isanzwe ikora neza. Ingingo z’umwuga zisobanura agaciro gatoyi k’ubudahangarwa bw’umubiri; ibisomwa biri musi y’ivyo bipimo bisaba ko umuntu avyina.

Uburyo bwo kugenzura neza

Uburyo bwo gucunga neza amashanyarazi (BMS) mu bikorwa vya litiyumu bikomeza gukurikirana umuriro, umuriro, n’ubushuhe mu ngirabuzimafatizo z’umuntu ku giti ciwe. Ivyuma vy’ubuhinga bwa none biramenya ibitari vyo vyerekana ko hariho ibintu bigufi bitera imbere mu bijanye n’ugukevya - voltage divaltage, kwitanga atavyiteze, n’uguhinduka kw’ubushuhe hagati y’ingingo.

Inyigisho z’imashini zamenyerejwe ku nyifato isanzwe y’amabati ishobora kumenya uburyo butari bwo bujanye n’imirongo y’imbere y’igihe. Icigwa cakozwe mu 2020 casohowe muRaporo za siyansiyerekanye ubuhinga bwo kwiga bugenzuwe bubona ko bateri y’imbere mu gihugu - n’ukuri gukomeye biciye mu gusuzuma umuriro n’imikono y’amashanyarazi mu gihe c’ingendo y’inguvu/ugukuraho.

Arc Fault Circuit Intercuit Intercutiters (AFCIs) zirinda amapantalo maremare y’imbere- igice c’igice c’inyuma kidakwegera amashanyarazi ahagije kugira ngo agende ku mavuta asanzwe. AFCIs zisesangura akaranga k’umupfunda w’umuyagankuba, zimenya imikono y’incuro nyinshi cane - Incuro zikozwe n’imirongo. Iyo imikono y’imirongo igaragara, AFCIs ihagarikira ububasha mu bice bitobito, ibuza umuriro umuriro.

Ingero zo kwirinda n'ingero z'umutekano

Ivyo birimwo no gukoresha ibikoresho vy’ubuhinga vy’ubunini bukwiye, kuguma ufise uburebure bukwiye bwo gukuraho ivyuma (kwirinda gukoresha ivyuma vy’ivyuma birenze urugero), gukoresha umuvuduko ukwiye ku bihe vyose vy’iherezo (mu bisanzwe 30-50% vy’inkomezi z’umusaruro w’umubano), no kumenya neza ko amasano yose akoresha ivyuma bihuye kugira ngo ntihagire ugusenyuka.

Ivyuma vy’umuyaga birahambaye cane-kuririnda gupfukama bisongoye, bikagumiza ahantu heza hagati y’ibikoresho vy’ubuhinga ku bushobozi butandukanye, bikaguma bikuramwo inkomoko z’ubushuhe, no kurinda intsinga ivyago vy’ubuhinga biciye ku bikoresho vy’imirongo canke ku bikoresho vy’intsinga. 2020 Itegeko ry’Igihugu ry’Igihugu ry’Igihugu (NEC) risobanura ivyo bisabwa, ariko mbere n’ibindi bishasha rimwe na rimwe vyo gushiramwo ibintu bigufi mu gihe canke mu gihe c’inguvu z’ingengo y’imari.

Ivyagezwe vy'uburinzi vy'umuriro

Ivyuma bimenagurika n’ibikoresho vy’ubuhinga bwa none bitanga uburinzi bw’umurongo w’imbere mu gucagura ububasha iyo ubu hariho umutekano. Guhitamwo bisaba ko uguhuza neza - abavuzi bategerezwa guhabwa amashanyarazi kugira ngo bashobore gukora amashanyarazi asanzwe ata n’imwe ituma umuntu agira ingorane mu gihe amashanyarazi y’ikosa yizigirwa yihuta kugira ngo ntangire.

Ivyo bimenyetso bihambaye ni "guhagarika igipimo" canke "AIC" (ampereje ubushobozi bwo guhagarika)- umuriro w'umurongo w'umurongo mugufi ushobora guca. Ivyo bikoresho bishobora gutuma umuntu ashobora kunanirwa cane igihe agerageza guhagarika amashanyarazi arengeye imipaka yavyo, bigatuma haba ingorane nyinshi aho gutanga uburinzi.

Fuses yishura vyihuta kuruta ibikoresho vyinshi bivunitse ariko bisaba gusubirira inyuma yo gukoreshwa. Mu bikorwa aho ugukuraho amakosa vyihuta ari ikintu gihambaye cane- nk’ugukingira ibikoresho vy’ubuhinga bwa none vy’ubuhinga bwa none{2}} Gukunda gutanga uburinzi bwiza cane naho nyene ingorane zidakora.

Gukingira ingorane

GFCIs (Igice c’Ikiruhuko c’Imirongo y’Imirongo y’Imirongo y’Iterambere) kirabona ubusumbasumbane bw’ubu bugaragaza amakosa yo hasi, ubushobozi bwo gutandukana mu 25- milisegonda milisegonda y’amamilisegonda ihagije kugira ngo ntizigire ama electrotis menshi. Ubu uburinzi bwa GFCI butegetswe n’amakode y’umuyagankuba mu bibanza bitose (ivyumba vyo kwogeramwo, ibikoni, hanze) kandi vyagabanyije cane urupfu rw’umuyagankuba kuva aho abantu benshi bafatwa mu myaka ya 1970.

Mu bibanza vy’inganda, ibikoresho vy’amakosa vyo hasi bitanga uburinzi busa n’ubwo ku mirongo minini, n’ugutahura n’ugucererwa kw’igihe kugira ngo bihuze n’imigambi yose y’uburinzi.

Gukurikirana n'ugucungera

Gusuzuma no gusanasana ibintu biguca mu nzira y’ugusesagura imbere y’uko bidakora neza. Igenzura ry’amashanyarazi ry’umwuga rikwiye kuba buri mwaka mu nyubakwa z’ubudandaji no mu myaka 3-5 mu bibanza vy’uburaro. Ivyo bipimo birimwo gusuzuma amashusho, gupima ubushuhe, no gupima ubushobozi bwo guhangana n’ibintu.

Uburinzi bw’ibidukikije buragura ubuzima bw’ibintu bizibira - kubungabunga urugero rw’ubushuhe n’ubukonje bikwiye, kubuza amazi kwinjira mu mazi, kugenzura ibisigazwa vy’amazi, no gukoresha ibikoresho vyo gukingira mu bidukikije vy’imiti. Mu gukoresha amabateri ya litiyumu, uburyo bwiza bwo gucunga ubushuhe burabuza electrolyte n’ugusenyuka kw’ibintu bituma umuntu ashobora gutandukana.

Uburyo bwo gukingira Imibare

Amabateri ya lithium yo muri iki gihe ashiramwo ibice vyinshi vy’uburinzi. Uburyo bwo gucunga ububiko bw’amazi (BMS) burakurikirana amashanyarazi y’umuntu ku giti ciwe, guca mu nzira canke umuzigo iyo amashanyarazi arengeye imipaka y’umutekano. Ivyo bikoresho bipima ibiharuro bidasanzwe vy’ugusohoka vyerekana ko bigufi, bikaba bituma habaho ugutandukana kw’ugukingira. Ivyuma bifata ubushuhe mu gihe cose c’ipaki bivuga ahantu hashushe vyerekana ko hari ingorane zo gutera imbere.

Uburinzi bw’umubiri burimwo ugushirwako kw’ingingo ngenderwako kugira ngo ubushuhe bukwiragire, urubeya{{0}== ibikoresho bitandukanye bishobora gutuma umuntu adakwiragizwa, n’ugutuma umukazo ugenda uhinduka umukazo imbere y’uko umukazo utera.

Iyo hasigaye ingendo zo gucagura incuro nyinshi iyo isubiwemwo, hariho ngufi idahera isaba ko umuntu asuzumwa.

Mu muriro w’amabateri ya litiyumu, ntukoreshe amazi ku mapaki manini.Amabateri y’ivyuma yitwa Lithium akora cane n’amazi. Naho umuriro mutoyi wa bateri ya litiyumu (nk’amatelefone) ushobora kuzima amazi, umuriro munini w’amabateri usaba ko usohoka mu rwego rwa D canke ifu y’umwihariko. Amabateri ya litiyumu ashobora guturika yoshobora gusubira kumera mbere n’inyuma y’aho biboneka ko azima, bikaba bisaba ko umuntu akurikirana igihe kirekire.

Isuzuma ry'umwuga

Abahinga mu vy’amashanyarazi bafise uruhusha barafise ibikoresho n’ubuhinga bwo gupima uruzitiro rugufi rudatekanye. Igenzura ry’umwuga ririho igerageza ry’ububasha bw’umurongo, igerageza ry’imirongo, kwitandukanya n’ibibanza vy’amakosa, amashusho y’ubushuhe kugira ngo hamenyekane uturere tw’ingorane, n’inyandiko z’uguhonyanga amategeko canke ingorane z’umutekano zabonetse mu gihe c’itohoza.

Ku bijanye n’ibikoresho vy’amabateri ya litiyumu, abahinga mu vy’amabateri yihariye bakwiye gusuzuma ubutungane bw’ibipapuro, kugerageza utugingo ngengabuzima ku giti cabo, gusuzuma ibikorwa vya BMS, no kumenya nimba amapaki ashobora gusubirwamwo ata nkomanzi kugira ngo akore igikorwa canke ategerezwa gusubirizwa yose. Utugingo ngengabuzima twashikiwe n’impuzu ngufi, naho yoba iboneka neza inyuma y’aho, yaragabanyije amafaranga y’umutekano n’ukwiyongera kw’ingorane zo kunanirwa.

Ivyiyumviro

Gusanura umurongo mugufi kuva ku gusubirira umugozi vyoroshe gushika ku gusubira gukora. Ibintu bikomeye birimwo:

Ugukurikiza amategeko- Ijambo ritegerezwa gushitsa ibisabwa n'amategeko y'umuyagankuba, bishobora kurenga ingingo ngenderwako z'intango zo gushiramwo. Inzu za kera cane cane zishobora gukenera guhindurwa cane kugira ngo zishike ku rugero rw’umutekano wo muri iki gihe.

Imizi ituma umuntu akurwaho- Gushiramwo ivyago biboneka ataco bivuze ku mpamvu z’ishimikiro (imirongo y’imirongo irengeje urugero, ubunini bw’intsinga zidahagije, ubukonje bw’ibidukikije) bituma habaho ukunanirwa.

Isuzuma ryose - isuzuma- ngufi mu nzira imwe yerekana ko hari ingorane zisa n’izo ahandi hantu, cane cane mu nyubakwa zifise amashanyarazi ashaje.

Ivyiyumviro bigufi vs Circuits: Gutahura Gutandukanya

Ivyuma bigufi bigereranya igice kimwe c'umurongo w'inzira-Ugufungura imirongo igereranya ibihushanye n'ibihushanye n'ivyo.

Imigeraumuzunguruko ufunguyebirimwo ubudahangarwa butagira iherezo- akaruhuko mu nzira yo kuyobora kugira ngo nta n’amazi atembe. Ingero ni nk’intsinga zicitse, amafuzi apfutse, canke ama switch afise amakosa. Mu gihe habaye umubabaro, imigwi yuguruye muri rusangi iratekanye. Voltage iriho mu ntumbero y’ugufungura, ariko zero tarm bisigura no kutagira ingorane yo gushusha canke gutera umuriro.

A umuzunguruko mugufibirimwo hafi y'i-hozero ubushobozi bw'inzira- Uwatari afise umugambi wo gukora inzira iremeza umuriro urenze urugero. Ivyo birateye akaga kubera ko uruja n’uruza rw’amashanyarazi rutera ubushuhe, bishobora gutuma umuriro utera, no gutuma haba ingorane z’uruzitiro. Igitero c’umuriro kiri mu nzira ngufi zero uko umuriro munini cane ugenda.

Itandukaniro rikomeye: imirongo yuguruye irabuza gukoresha ibikoresho ataco igaragaza, mu gihe imirongo miremire ikora n’umwete akaga mbere n’igihe ibikoresho bigenewe bitakora. Ivyo vyose bigereranya amakosa, ariko imirongo miremire isaba gukosora ubwo nyene mu gihe imirongo yuguruye isaba gusa gusanurwa.

Mu guhingura umurongo w’uburinzi, ituma habaho n’ibigirankana imirongo yuguruye (mu gushongera) kugira ngo ntihagire imirongo miremire idashobora gutuma habaho ivyago vyinshi- tracting strics kugira ngo umuntu agire umutekano.
