Chitetezo cha zida zapakhomo chikukhala chofunikira kwambiri kwa aliyense.Pofuna kuonetsetsa chitetezo chamagetsi, zida zamitundu yonse zomwe zimatha kuswa dera zapangidwa.Zimaphatikizapo zida zotetezera maopaleshoni, zomangira mphezi, Zida Zotsalira Zamakono (RCD kapena RCCB), zoteteza kwambiri.Koma aliyense sadziwa kuti pali kusiyana kotani pakati pa mitundu iyi ya zida zodzitetezera.Tsopano tiwona kusiyana pakati pa oteteza chitetezo, zomangira mphezi, zoteteza kutayikira kwapano, zoteteza kwambiri.Ndikukhulupirira kuti ikhoza kukhala yothandiza kwa aliyense.

1. Kusiyana Pakati pa Surge Protector ndi Air Break Switch

(1).Woteteza Chitetezo

Chipangizo choteteza mphezi (SPD), chomwe chimadziwikanso kuti "mphezi yoteteza mphezi" ndi "chomangirira mphezi", ndikuchepetsa mawotchi opangidwa ndi mphamvu yamagetsi yopitilira muyeso wamagetsi ndi mizere yolumikizirana kuti ateteze zida.Mfundo yake yogwirira ntchito ndi yakuti pakakhala kuwonjezereka kwamagetsi kapena kupitirira-panopa pamzere, wotetezera opaleshoni amatsegula ndikutulutsa kuphulika kwa mzere pansi mwamsanga.

Zida zosiyanasiyana zodzitchinjiriza zitha kugawidwa m'mitundu iwiri: chitetezo champhamvu komanso chitetezo chamagetsi.
ndi.Woteteza mphamvu yowonjezera mphamvu akhoza kukhala woteteza mphamvu yowonjezera mphamvu yoyamba, kapena chitetezo chamagetsi chachiwiri, kapena chitetezo chachitatu chamagetsi, kapena chitetezo chamagetsi chachinayi malinga ndi mphamvu zosiyana za mphamvu zomwezo.
ii.Oteteza ma Signal Surge amatha kugawidwa m'magulu: oteteza ma siginecha a ma network, oteteza mavidiyo, kuyang'anira oteteza atatu mwa amodzi, oteteza ma siginecha oteteza, oteteza ma siginecha a antenna, ndi zina zambiri.

(2)Chipangizo Chamakono Chotsalira (RCB)

RCD imatchedwanso kusinthana kwaposachedwa komanso Residual Current Circuit Breaker (RCCB).Amagwiritsidwa ntchito kwambiri kuteteza zida kuti zisawonongeke ndikuwonongeka kwamagetsi komwe kuli ndi ngozi yowopsa.Ili ndi ntchito zolemetsa komanso zodzitchinjiriza zazifupi ndipo zimatha kugwiritsidwa ntchito kuteteza dera kapena mota kuti lisakule kwambiri komanso kuti zisawonongeke.Itha kugwiritsidwanso ntchito pakusintha kosasintha ndikuyambitsa dera munthawi yanthawi zonse.

Palinso dzina lina la RCD, lomwe limatchedwa "Residual Current Circuit Breaker" lomwe limazindikira mphamvu yotsalira.Imagawidwa m'magawo atatu: chinthu chodziwikiratu, makina okulitsa apakati ndi actuator.

Chidziwitso - gawo ili ndi chinthu chofanana ndi thiransifoma ya zero.Chigawo chachikulu ndi mphete yachitsulo (koyilo) yokulungidwa ndi mawaya, ndipo mawaya osalowerera ndale ndi amoyo amadutsa pa koyilo.Amagwiritsidwa ntchito kuyang'anira zamakono.Nthawi zonse, pali waya wosalowerera komanso waya wamoyo mu koyilo.Njira yamakono mkati mwa mawaya awiriwa iyenera kukhala yotsutsana ndipo kukula kwake kuli kofanana.Nthawi zambiri kuchuluka kwa ma vector awiriwa ndi ziro.Ngati pali kutayikira m'derali, gawo lina lamagetsi limatuluka.Ngati kudziwika kwachitika, kuchuluka kwa ma vector sikukhala ziro.Ikazindikira kuti kuchuluka kwa ma veta si 0, chinthu chodziwikiratu chidzapereka chizindikirochi ku ulalo wapakatikati.

Makina okulitsa apakati - ulalo wapakatikati umaphatikizapo amplifier, comparator ndi unit unit.Chizindikiro chotuluka kuchokera ku chinthu chodziwikiratu chikalandiridwa, ulalo wapakatikati udzakulitsidwa ndikuperekedwa kwa actuator.

Actuating limagwirira - makinawa amapangidwa ndi maginito amagetsi ndi lever.Ulalo wapakatikati ukakulitsa chizindikiro chotuluka, maginito amagetsi amapatsidwa mphamvu kuti apange mphamvu ya maginito, ndipo lever imayamwa pansi kuti amalize kudumpha.

(3) Woteteza kwambiri-voltage

Overvoltage protector ndi chipangizo chamagetsi choteteza chomwe chimalepheretsa kuphatikizika kwa mphezi ndikugwira ntchito mopitilira muyeso.Amagwiritsidwa ntchito makamaka kuteteza kutsekemera kwa zida zamagetsi monga ma jenereta, ma transformer, vacuum switch, mipiringidzo ya mabasi, ma motors, ndi zina zambiri.

2. Kusiyana Pakati pa Surge Protector, RCB ndi Overvoltage Protectors

(1) Kusiyana Pakati pa Surge Protector ndi RCD

i. RCD ndi chida chamagetsi chomwe chimatha kulumikiza ndikuchotsa gawo lalikulu.Ili ndi ntchito zoteteza kutayikira (kugwedezeka kwamagetsi kwa thupi laumunthu), chitetezo chochulukira (kuchulukirachulukira), komanso chitetezo chachifupi (chifupifupi);

ii.Ntchito yoteteza chitetezo ndikuteteza mphezi.Pakakhala mphezi, imateteza mabwalo ndi zida zamagetsi.Siziwongolera mzere ngati zimathandizira pachitetezo.

Pakakhala kuzungulira kwachidule kapena kutayikira kapena kutsika pang'ono pansi pagawo (monga chingwe chikathyoka, ndipo chapano ndi chachikulu kwambiri), RCD imangoyenda kuti isawotche dera.Mphamvu yamagetsi ikakwera mwadzidzidzi kapena kugunda kwamphezi, woteteza chitetezo amatha kuteteza dera kuti apewe kukula kwamtunduwu.Woteteza opaleshoni nthawi zina amatchedwa womanga mphezi m'moyo watsiku ndi tsiku.

(2) Kusiyana Pakati pa Surge Protector ndi Over-voltage Protector

Ngakhale onse ali ndi chitetezo champhamvu kwambiri, chitetezo chachitetezo chimateteza ku zoopsa zomwe zimachitika chifukwa champhamvu kwambiri komanso kuchuluka kwamphamvu komwe kumachitika chifukwa cha mphezi.Woteteza overvoltage amateteza ku zoopsa zomwe zimachitika chifukwa cha mphezi kapena voteji ya gridi yochulukirapo.Chifukwa chake, kuchuluka kwamagetsi komanso kupitilira apo komwe kumachitika chifukwa cha mphezi ndizovuta kwambiri kuposa zomwe zimayambitsidwa ndi gridi yamagetsi.

RCD imayang'anira zomwe zilipo pokhapokha popanda mphamvu yamagetsi.Powonjezera ntchito zachitetezo cha maopaleshoni ndi chitetezo chamagetsi mopitilira muyeso, RCD imatha kuteteza magetsi ndi magetsi kuti ipewe kukwera kwadzidzidzi kwamagetsi komwe kumawononga anthu ndi zida.
