Kukhazikitsa njira yolumikizira mphamvu yowonjezera mphamvu
1. Ikani chomangira mphezi yamagetsi molumikizana. Kuyika kwa makina amakala ndikumapeto kumbuyo kwa bolodi kapena chosinthira mpeni (wophwanyira dera) mkalasi ya malo owonera satellite. Gwiritsani ntchito ma seti anayi akukulitsa pulasitiki ya M8 ndi zomangira zofananira zodzigunda. pa khoma.
2. Kukula koyikirako (70 × 180) ndi mabowo ogwirizana nawo pa chomangira mphamvu ayenera kubowoleredwa pakhoma.
3. Lumikizani magetsi. Waya wamoyo wa chomangira magetsi ndi ofiira, waya wosalowerera ndale ndi wabuluu, ndipo malo odutsa ndi BVR6mm2. Waya wamkuwa wamitundu yambiri, waya wapansi wa makina amakala ndi wachikasu komanso wobiriwira, ndipo malo ozungulira ndi BVR10m m2. Waya wamkuwa wokhazikika, kutalika kwa mawaya kumakhala kochepa kapena kofanana ndi 500mm. Ngati malirewo ndi ocheperapo kapena ofanana ndi 500mm, amatha kukulitsidwa moyenerera, koma mfundo yosunga waya yayifupi momwe mungathere iyenera kutsatiridwa, ndipo ngodya iyenera kukhala yayikulu kuposa madigiri a 90 (arc osati kumanja).
4. Lumikizani magetsi kwa woyendetsa mphezi. Mapeto amodzi a chingwe chomangira mphamvu amakhala molunjika komanso mokhazikika mpaka pofikira chomangira mphamvu. Waya wapansi amalumikizidwa ku gululi wodziyimira pawokha kapena waya woyambira magawo atatu woperekedwa ndi sukulu.

Njira zodzitetezera pakukhazikitsa chomanga chamagetsi
1. Njira yolumikizira ma waya
Pamene chomangira mphezi chikuyikidwa, zolowetsamo ndi zotulukapo siziyenera kulumikizidwa mozungulira, apo ayi, mphamvu yoteteza mphezi idzakhudzidwa kwambiri, ndipo ngakhale ntchito yanthawi zonse ya zidayo idzakhudzidwa. Mapeto olowera a chomangira mphezi amagwirizana ndi njira yofalikira ya mphezi, ndiko kuti, kumapeto kwa chodyetsa, ndipo kumapeto kwake ndikuteteza zida.
2. Njira yolumikizira
Pali mitundu iwiri ya njira zamawaya: kulumikizana kwa mndandanda ndi kulumikizana kofananira. Nthawi zambiri, njira yolumikizira ma terminal ndi yomwe imagwiritsidwa ntchito pamalumikizidwe angapo, ndipo njira ina yolumikizira imagwiritsidwa ntchito munjira yolumikizirana. Waya wosalowerera ndale wa chingwe chamagetsi amalumikizidwa ndi dzenje la "N" la mphamvu ya SPD, ndipo pamapeto pake waya wapansi wochokera ku dzenje la "PE" la mphamvu ya SPD amalumikizidwa kuchitetezo cha mphezi kapena malo otchingira mphezi. Kuonjezera apo, malo ocheperapo amtundu wa waya wogwirizanitsa wa womanga mphezi ayenera kutsatira zofunikira za polojekiti ya chitetezo cha mphezi ya dziko.

3. Kulumikizana kwa waya pansi
Kutalika kwa waya wapansi kuyenera kukhala kwaufupi momwe kungathekere, nsonga imodzi iyenera kudulidwa mwachindunji ku terminal ya chomangira mphezi, ndipo waya wapansi uyenera kulumikizidwa ndi netiweki yodziyimira payokha (yopanda kuyika magetsi) kapena yolumikizidwa ndi waya wokhazikika mugawo la magawo atatu amagetsi.
4. Kuyika malo
Chomangira mphezi yamagetsi nthawi zambiri chimagwiritsa ntchito njira yodzitetezera. Ikani chipangizo choyambirira chotetezera mphezi pa kabati yayikulu yogawa mphamvu yanyumbayo. Kachiwiri, ikani chipangizo chachiwiri chotetezera mphezi pamagetsi ang'onoang'ono anyumbayo pomwe zida zamagetsi zili. Pamaso pa zida zofunika kwambiri zamagetsi, ikani chomangira mphezi yamagetsi atatu, ndipo nthawi yomweyo, onetsetsani kuti palibe zinthu zoyaka komanso zophulika pafupi ndi kuyikapo kuti muteteze moto womwe umabwera chifukwa cha zoyaka zamagetsi.
5. Kuzimitsa ntchito
Pakuyika, magetsi ayenera kuchotsedwa, ndipo ntchito yamoyo ndiyoletsedwa. Asanayambe kugwira ntchito, multimeter iyenera kugwiritsidwa ntchito kuyesa ngati mabasi kapena ma terminals a gawo lililonse azimitsidwa.
6. Yang'anani mawaya
Onani ngati mawaya alumikizana. Ngati pali kukhudzana, gwirani nazo nthawi yomweyo kuti mupewe kuchepa kwa zida. Kuyika kwa chomangira mphezi kumalizidwa, ziyenera kufufuzidwa nthawi zonse kuti muwone ngati kugwirizana kuli kotayirira. Zikapezeka kuti chipangizo choteteza mphezi sichikugwira ntchito bwino kapena kuwonongeka, mphamvu yoteteza mphezi ya chipangizo choteteza mphezi idzawonongeka, ndipo iyenera kusinthidwa nthawi yomweyo.

Common magawo a mphamvu mphezi zomangira
1. Nominal voltage Un:
Mphamvu yamagetsi yamagetsi otetezedwa imagwirizana. M'dongosolo laukadaulo wazidziwitso, chizindikiro ichi chikuwonetsa mtundu wa chitetezo chomwe chiyenera kusankhidwa. Imawonetsa mtengo wa rms wamagetsi a AC kapena DC.
2. Mphamvu yamagetsi Uc:
Itha kugwiritsidwa ntchito kumapeto kwachitetezo kwa nthawi yayitali osasintha mawonekedwe achitetezo ndikuyambitsa mphamvu yayikulu ya RMS ya chinthu choteteza.
3. Kutulutsa kwaposachedwa kwa Isn:
Pamene mphezi yokhazikika yokhala ndi mawonekedwe a mafunde a 8/20μs iyikidwa pachitetezo kwa nthawi 10, kuchuluka kwamphamvu komwe wotetezayo angakwanitse.
4. Imax yotulutsa kwambiri pano:
Pamene mphezi yokhazikika yokhala ndi mawonekedwe a 8/20μs ikagwiritsidwa ntchito pachitetezo kamodzi, kuchuluka kwapamwamba komwe wotetezayo angakwanitse.
5. Kutetezedwa kwa Voltage Kukwera:
Mtengo wapamwamba wa chitetezo mu mayesero otsatirawa: magetsi a flashover ndi otsetsereka a 1KV / μs; voteji yotsalira ya ovoteledwa discharge current.
6. Nthawi yoyankhira TA:
Chidziwitso chakuchitapo kanthu ndi nthawi yowonongeka ya chinthu chapadera chodzitchinjiriza chomwe chimawonetsedwa makamaka muchitetezo chimasiyana pakapita nthawi kutengera kutsetsereka kwa du/dt kapena di/dt.
7. Mlingo wotumizira ma data vs:
Imawonetsa kuchuluka kwa ma bits omwe amafalitsidwa mu sekondi imodzi, unit: bps; ndizomwe zimatchulidwa pakusankha kolondola kwa zida zoteteza mphezi munjira yotumizira deta. Kuchulukitsa kwa data kwa zida zoteteza mphezi kumadalira njira yopatsira dongosolo.
8. Kutayika kolowetsa Ae:
Chiŵerengero cha ma voltages isanayambe kapena itatha kuyika kwachitetezo pafupipafupi.
9. Kubweza kutaya Ar:
Imayimira gawo la mafunde akutsogolo omwe amawonetsedwa pa chipangizo choteteza (reflection point), ndipo ndi chizindikiro chomwe chimayang'ana mwachindunji ngati chida choteteza chikugwirizana ndi kusokoneza dongosolo.
10. Kutulutsa kwakutali kotalika:
Zimatanthawuza nsonga yapamwamba kwambiri yomwe wotetezera amatha kupirira pamene mphezi yokhazikika yokhala ndi mawonekedwe a 8/20μs iyikidwa pansi kamodzi.
11. Kuchulukitsitsa kofananira ndi kutulutsa panopa:
Pamene mphezi yokhazikika yokhala ndi mawonekedwe a 8/20μs ikayikidwa pakati pa mzere wa chala ndi mzere, kuchuluka kwapamwamba komwe kungathe kupirira.
12. Kusokoneza pa intaneti:
Imatanthawuza kuchuluka kwa loop impedance ndi inductive reactance yomwe ikuyenda kudzera pachitetezo pamagetsi odziwika a Un. Nthawi zambiri amatchedwa "system impedance".
13. Kutulutsa kwapamwamba kwambiri:
Pali mitundu iwiri: ovotera kutulutsa kwaposachedwa kwa Isn ndi Imax yotulutsa pakali pano.
14. Kutayikira panopa:
Zimatanthawuza mphamvu yamagetsi ya DC yomwe ikuyenda kudzera pachitetezo pamagetsi amtundu wa Un a 75 kapena 80.
