Kodi chomanga mphezi ndi chiyani?Kodi chitetezo cha surge ndi chiyani?Opanga magetsi omwe akhala akugwira ntchito yamagetsi

kwa zaka zambiri ayenera kudziwa bwino izi.Koma zikafika pa kusiyana pakati pa zomangira mphezi ndi kuwomba

oteteza, ambiri ogwira ntchito zamagetsi sangathe kuwauza kwa kanthawi, ndipo ena oyambitsa magetsi ali ofanana

kusokonezeka kwambiri.Tonse tikudziwa kuti zomangira mphezi zimagwiritsidwa ntchito kuteteza zida zamagetsi kuti zisawonongeke kwambiri

zoopsa pa kugunda kwamphezi, ndi kuchepetsa nthawi ya freewheeling ndipo nthawi zambiri kuchepetsa matalikidwe a freewheeling.Mphezi

zomangira nthawi zina amatchedwanso overvoltage protectors ndi overvoltage limiters.

Woteteza opaleshoni, yemwe amadziwikanso kuti chitetezo cha mphezi, ndi chipangizo chamagetsi chomwe chimapereka chitetezo chachitetezo

zida zosiyanasiyana zamagetsi, zida, ndi mizere yolumikizirana.Pamene pachimake chamakono kapena voteji mwadzidzidzi zimachitika

mu dera magetsi kapena kulankhulana mzere chifukwa cha kusokoneza kunja, akhoza kuchita shunt mu nthawi yochepa kwambiri

pewani kuwonongeka kwa zida zina zozungulira.Kotero, pali kusiyana kotani pakati pa chomanga mphezi ndi chiwombankhanga

mtetezi?Pansipa tiyerekeza kusiyana kwakukulu kwakukulu pakati pa zomangira mphezi ndi oteteza ma opaleshoni, kuti inu

amatha kumvetsetsa bwino ntchito zomwe zimagwira ntchito zomangira mphezi ndi chitetezo champhamvu.Nditawerenga nkhaniyi,

Ndikukhulupirira kuti idzapatsa ogwira ntchito zamagetsi kumvetsetsa mozama za zotchinga mphezi ndi zoteteza ma opaleshoni.

01 Udindo wa oteteza maopaleshoni ndi omanga mphezi

1. Chitetezo cha Surge: Chitetezo cha Surge chimatchedwanso surge protector, low-voltage power supply mphezi chitetezo, mphezi

chitetezo, SPD, etc. Ndi chipangizo chamagetsi chomwe chimapereka chitetezo chazida zosiyanasiyana zamagetsi, zida,

ndi mizere yolumikizana.Ndi chipangizo chamagetsi chomwe chimapereka chitetezo chazida zosiyanasiyana zamagetsi,

zida, ndi mizere yolumikizirana.Pamene pachimake panopa kapena voteji mwadzidzidzi kumachitika mu dera magetsi kapena

chingwe cholumikizirana chifukwa cha kusokonezedwa kwakunja, woteteza maopaleshoni amatha kuyendetsa ndikutchingira zomwe zikuchitika munthawi yochepa kwambiri,

potero kulepheretsa kuphulikako kuti zisawononge zida zina muderali.

Kuphatikiza pa kugwiritsidwa ntchito m'munda wamagetsi, zoteteza ma opaleshoni ndizofunikiranso m'magawo ena.Monga chipangizo chotetezera, iwo

onetsetsani kuti zida zimachepetsa zotsatira za ma surges panthawi yolumikizana.

2. Chomangira mphezi: Chomangira mphezi ndi chipangizo choteteza mphezi chomwe chimagwiritsidwa ntchito kuteteza zida zamagetsi ku zoopsa.

kuchulukirachulukira kwakanthawi panthawi yamphezi, komanso kuchepetsa nthawi yaulere ndikuchepetsa matalikidwe a freewheeling.

Chomanga mphezi nthawi zina chimatchedwanso over-voltage arrester.

Chotsekera mphezi ndi chipangizo chamagetsi chomwe chimatha kutulutsa mphezi kapena mphamvu zochulukirapo panthawi yamagetsi,

tetezani zida zamagetsi ku ngozi zomwe zimangowonjezera mphamvu nthawi yomweyo, ndikudula ma freewheeling kuti mupewe kukhazikika kwadongosolo

dera lalifupi.Chipangizo cholumikizidwa pakati pa kondakita ndi pansi kuti chiteteze kugunda kwa mphezi, nthawi zambiri chimakhala chofanana ndi

zida zotetezedwa.Zomanga mphezi zimatha kuteteza zida zamagetsi.Mphamvu yamagetsi ikachitika, womanga

adzachita ndikuchita ntchito yoteteza.Pamene mtengo wamagetsi uli wabwinobwino, womangidwayo adzabwereranso kumalo ake oyambirira kuti atsimikizire

mphamvu yachibadwa ya dongosolo.

Zomanga mphezi zingagwiritsidwe ntchito osati kungoteteza ku mphepo zam'mlengalenga, komanso kugwiritsira ntchito mphamvu zambiri.

Ngati pali mvula yamkuntho, mphamvu yayikulu idzachitika chifukwa cha mphezi ndi bingu, ndipo zida zamagetsi zitha kukhala pachiwopsezo.

Panthawiyi, womanga mphezi adzagwira ntchito kuteteza zipangizo zamagetsi kuti zisawonongeke.Chachikulu komanso chofunikira kwambiri

ntchito ya chomangira mphezi ndi kuchepetsa overvoltage kuteteza zipangizo zamagetsi.

Chotsekereza mphezi ndi chipangizo chomwe chimalola kuti mphezi ziziyenda padziko lapansi ndikuletsa zida zamagetsi kuti zisatuluke

voteji yapamwamba.Mitundu yayikulu imaphatikizapo zomangira zamtundu wa chubu, zomangira zamtundu wa ma valve, ndi zomangira zinc oxide.Mfundo zazikuluzikulu zogwirira ntchito

za mtundu uliwonse wa zomangira mphezi ndizosiyana, koma ntchito yawo ndi yofanana, yomwe ndi kuteteza zida zamagetsi kuti zisawonongeke.

02 Kusiyana pakati pa zomangira mphezi ndi zoteteza maopaleshoni

1. Miyezo yamagetsi yogwiritsidwa ntchito ndi yosiyana

Zomanga mphezi: Zomanga mphezi zimakhala ndi ma voltages angapo, kuyambira 0.38KV low voltage mpaka 500KV Ultra-high voltage;

Chitetezo cha Surge: Chitetezo cha Surge chili ndi zinthu zotsika kwambiri zokhala ndi ma voltage angapo kuyambira AC 1000V ndi DC 1500V.

2. The anaika machitidwe ndi osiyana

Chomangira mphezi: nthawi zambiri chimayikidwa pamakina oyambira kuti asalowe mwachindunji mafunde amphezi;

Chitetezo cha Surge: Choyikidwa pa dongosolo lachiwiri, ndi njira yowonjezera pambuyo poti womangayo athetse kulowerera kwachindunji.

wa mafunde amphezi, kapena pamene womanga alephera kuthetsa mafunde amphezi kotheratu.

3. Malo oyika ndi osiyana

Chomangira mphezi: Nthawi zambiri chimayikidwa pa kabati yamagetsi apamwamba kutsogolo kwa thiransifoma (nthawi zambiri imayikidwa mudera lomwe likubwera.

kapena dera lotuluka la kabati yogawa kwambiri-voltage, ndiko kuti, kutsogolo kwa thiransifoma);

Chitetezo cha Surge: SPD imayikidwa mu kabati yogawa magetsi otsika pambuyo pa thiransifoma (nthawi zambiri imayikidwa polowera

otsika-voteji kugawa kabati, ndiko kuti, kutulukira kwa thiransifoma).

4. Maonekedwe ndi kukula kwake kosiyana

Chomangira mphezi: Chifukwa cholumikizidwa ndi makina oyambira magetsi, chiyenera kukhala ndi ntchito yokwanira yotsekera kunja

ndi mawonekedwe owoneka bwino;

Chitetezo cha Surge: Chifukwa cholumikizidwa ndi makina otsika kwambiri, amatha kukhala ochepa kwambiri.

5. Njira zoyambira pansi

Chomangira mphezi: nthawi zambiri njira yokhazikika yokhazikika;

Chitetezo cha Surge: SPD imalumikizidwa ndi mzere wa PE.
