Mubikoresho byinsinga ninsinga, ibikoresho byo gukingira bigabanijwemo ibitekerezo bibiri bitandukanye: gukingira amashanyarazi no gukingira amashanyarazi. Ikingira rya electromagnetic rikoreshwa cyane cyane mukurinda insinga zumurongo mwinshi (nkinsinga za RF hamwe ninsinga za elegitoronike) zitera kwivanga mubidukikije cyangwa guhagarika imiyoboro ya electromagnetiki yo hanze itabangamira insinga zanduza imiyoboro idakomeye (nk'ibimenyetso n'ibipimo byo gupima), ndetse no kugabanya kwivanga hagati yinsinga. Ku rundi ruhande, amashanyarazi akingira amashanyarazi, agenewe kuringaniza imirima ikomeye y’amashanyarazi hejuru yuyobora cyangwa hejuru yubushyuhe bwinsinga ziciriritse n’umuriro mwinshi.
1. Imiterere nibisabwa byumuriro wamashanyarazi
Gukingira insinga z'amashanyarazi bigabanijwemo gukingira imiyoboro, gukingira izirinda, no gukingira ibyuma. Ukurikije ibipimo bifatika, insinga zifite ingufu zapimwe zirenze 0,6 / 1 kV zigomba kugira icyuma gikingira icyuma, gishobora gukoreshwa kumurongo wihariye cyangwa insinga rusange. Ku nsinga zifite voltage yagabanutse byibuze 3.6 / 6 kV ukoresheje XLPE (ihuza polyethylene ihuza), cyangwa insinga zifite voltage yagabanutse byibuze 3.6 / 6 kV ukoresheje insimburangingo ya EPR yoroheje (etylene propylene reberi) (cyangwa iziritse cyane hamwe na voltage yagereranijwe byibura 6/10 kV), harakenewe kandi uburyo bwo gukingira imbere.
(1) Gukingira Kiyobora no Gukingira
Shielding Shielding (Imbere ya Semi-Conductive Shielding): Ibi bigomba kuba bitari ibyuma, bigizwe nibikoresho byacishijwe bugufi cyangwa guhuza kaseti ya kaburimbo yazengurutswe n'umuyoboro hanyuma bigakurikirwa n'ibikoresho bitwara igice.
Gukingira Gukingira (Shitingi yo hanze)
Ibice byimbere byimbere ninyuma byigice bigomba guhuzwa cyane na insulasiyo, hamwe ninteruro yoroshye itarangwamo ibimenyetso byerekana imiyoboro ihagaze, impande zikarishye, ibice, gutwika, cyangwa gushushanya. Kurwanya mbere na nyuma yo gusaza ntibigomba kurenza 1000 Ω · m kurwego rwo gukingira imiyoboro kandi ntibirenze 500 Ω · m kurwego rwo gukingira.
Ibikoresho byo gukingira imbere n'inyuma bikozwe mu kuvanga ibikoresho bikwiranye (nka polyethylene (XLPE) hamwe na reberi ya Ethylene propylene (EPR) hamwe ninyongeramusaruro nka karubone yumukara, imiti irwanya gusaza, hamwe na Ethylene-vinyl acetate copolymer. Ibice byirabura bya karubone bigomba gukwirakwizwa muri polymer, nta agglomeration cyangwa ikwirakwizwa nabi.
Ubunini bwimbere ninyuma igice-cyuma gikingira ibice byiyongera hamwe na voltage igipimo. Kubera ko ingufu z'umuriro w'amashanyarazi kurwego rwo hejuru ziri hejuru imbere no hepfo hanze, ubunini bwikigice cyo gukingira igice nacyo kigomba kuba kinini imbere kandi cyoroshye hanze. Ku nsinga zapimwe kuri 6 ~ 10 ~ 35 kV, uburebure bwimbere bwimbere buri hagati ya 0.5 ~ 0,6 ~ 0.8 mm.
(2) Gukingira ibyuma
Intsinga zifite voltage yagereranijwe irenga 0,6 / 1 kV igomba kugira icyuma gikingira icyuma. Icyuma gikingira icyuma kigomba gupfuka hanze ya buri cyuma gikingiwe cyangwa insinga ya kabili. Gukingira ibyuma birashobora kuba bigizwe na kaseti imwe cyangwa nyinshi zicyuma, imiringa yicyuma, ibice byibanze byinsinga zicyuma, cyangwa guhuza insinga nicyuma.
Mu Burayi no mu bihugu byateye imbere, aho hakoreshwa uburyo bwo kurwanya-imiyoboro ibiri-y’umuzunguruko kandi imiyoboro ngufi ikaba ndende, hakoreshwa uburyo bwo gukingira insinga z'umuringa. Mubushinwa, guhagarika arc coil-ground-sisitemu imwe yo gutanga amashanyarazi birasanzwe, bityo gukingira kaseti y'umuringa bisanzwe bikoreshwa. Uruganda rukora insinga rwaguze kaseti zikomeye zumuringa mukunyerera no gufunga kugirango woroshye mbere yo kuzikoresha. Kaseti y'umuringa yoroshye igomba kubahiriza GB / T11091-2005 “Ikariso y'umuringa ku nsinga”.
Gukingira kaseti y'umuringa bigomba kuba bigizwe nigice kimwe cyumuringa woroshye wuzuye umuringa cyangwa ibice bibiri byumuringa wuzuye umuringa. Ikigereranyo cyo guhuzagurika kigomba kuba 15% by'ubugari bwa kaseti, hamwe byibuze byibuze bitarenze 5%. Ubunini bw'izina bwa kaseti y'umuringa ntibugomba kuba munsi ya 0,12 mm kuri insinga imwe-imwe kandi ntibiri munsi ya 0,10 mm kuri insinga nyinshi. Umubyimba ntarengwa ntugomba kuba munsi ya 90% yagaciro kizina.
Gukingira insinga z'umuringa bigizwe no gukomeretsa byoroheje insinga z'umuringa, hamwe n'ubuso bwarinzwe n'insinga z'umuringa zizingiye inyuma. Kurwanya kwayo kugomba kubahiriza ihame rya GB / T3956-2008 “Abayobora insinga”, kandi agace kayo kambukiranya ibice kagomba kugenwa hashingiwe ku bushobozi buriho.
2. Imikorere ya Shielding Layers nubusabane bwabo nu mibare ya voltage
(1) Imikorere Yimbere na Hanze Semi-Imyitozo ngororamubiri
Imiyoboro ya kabili isanzwe igizwe ninsinga nyinshi zahagaritswe kandi zegeranye. Mugihe cyo gukuramo insulasiyo, icyuho cyaho, burrs, cyangwa ubusumbane bwubuso hagati yubuso bwumuyoboro hamwe nigitereko cyizuba gishobora gutera umurima wumuriro wamashanyarazi, bigatuma habaho gusohora igice no gusohora ibiti, bitesha agaciro amashanyarazi. Mugukuramo igice cyibikoresho bitwara igice (gukingira kiyobora) hagati yubuso bwikigero nigitereko, birashobora guhuza cyane nubushake. Kubera ko igice cya kabiri cyayobora kiri mubushobozi bumwe nuyobora, icyuho cyose kiri hagati yacyo ntikizagira ingaruka kumashanyarazi, bityo bikarinda gusohoka igice.
Mu buryo busa nabwo, icyuho kiri hagati yubuso bwinyuma hamwe nicyuma (cyangwa icyuma gikingira icyuma) nacyo gishobora gutuma habaho gusohora igice, cyane cyane kurwego rwo hejuru rwa voltage. Mugukuramo igice cyibikoresho bitwara ibintu (gukingira izirinda) hejuru yubuso bwinyuma, bikora ubuso bwibikoresho hamwe nicyuma cyicyuma, bikuraho ingaruka zumuriro wamashanyarazi mubyuho kandi bikarinda gusohoka igice.
(2) Imikorere yo Gukingira Ibyuma
Imikorere yo gukingira ibyuma harimo: kuyobora imiyoboro ya capacitif mu bihe bisanzwe, ikora nkinzira yumuyaga mugufi (amakosa), gufunga umurima wamashanyarazi mumashanyarazi (kugabanya ingufu za electronique magnetique kubidukikije byo hanze), no kwemeza amashanyarazi amwe (imirima yumuriro wa radiyo). Muri sisitemu y'ibyiciro bitatu-insinga enye, ikora kandi nk'umurongo utabogamye, utwara imigezi idahwitse, kandi utanga amashanyarazi adasanzwe.
3. Ibyerekeye umugozi wa OW
Nkumuyobozi wambere utanga ibikoresho fatizo byinsinga ninsinga, OW Cable itanga ubuziranenge bwo hejuru buhuza polyethylene (XLPE), kaseti y'umuringa, insinga z'umuringa, nibindi bikoresho bikingira bikoreshwa cyane mugukora insinga z'amashanyarazi, insinga z'itumanaho, n'insinga zidasanzwe. Ibicuruzwa byacu byujuje ubuziranenge mpuzamahanga, kandi twiyemeje gutanga ibisubizo byizewe bikingira abakiriya bacu.
