Ndeupi Musiyano Uripo Pakati peAC neDC?

Sechinhu chikuru mugridi yemagetsi, Masimba Anoshandura ndiwo musimboti wekuti tinogovera uye tinoshandisa sei magetsi. Asi magetsi anoyerera kuburikidza nematransformer aya anouya mumhando mbiri huru: Alternating Current (AC) uye Direct Current (DC). Kunzwisisa musiyano kwakakosha pakunzwisisa masisitimu emagetsi emazuva ano.

Pa[Sangano reHutano hweVeruzhinji], nyanzvi munetransformer yemagetsiPakugadzira, tinoshandisa simba reAC zuva nezuva. Muchinyorwa chino, tichatsanangura zvakajeka musiyano uripo pakati peAC neDC, nei AC yakava chiyero chemagridi emagetsi, uye kuti DC inokosha papi.

Musiyano Mukuru: Kufananidza Kuri Nyore

Fungidzira kuyerera kwemagetsi semvura iri kuyerera mupombi.

 

Kutungamira Kwemagetsi (DC)zvakaita semvura inoyererazvishoma nezvishoma uye nguva dzose munzira imwe chetepasi pepombi yakatwasuka. Zvinofungidzirwa uye zvakafanana.

Kuchinjana Kwemagetsi (AC)zvakaita semvurakumhanya-mhanya uchidzokera shure uchidzoka nekudzoka zvichitevedzanamupaipi. Kufamba kwemhepo hakuna kukwana, asi simba richiri kufambiswa kuburikidza nekufamba kwacho.

 

Musiyano uyu mukuru mugwara rekuyererandiyo musimboti weAC neDC.

 

 

Kuenzanisa Padivi Nepadivi: AC vs. DC

 

 

Kunyura Zvakadzika Mumisiyano Yakakosha

1. Kuyerera Kwazvino uye Kutungamira

DC:Chinhu chikuru apa ndechekutiZvakanangaChaja yemagetsi inoyerera nenzira imwe chete, isingazununguki kubva pane positive kuenda kune negative terminal. Funga nezve tochi inoshandisa bhatiri; simba racho rinoyerera zvakananga kubva pabhatiri kuenda kubharubhu.

UYE:Chinhu chikuru apa ndechekutiKuchinjana. Chaja yemagetsi inodzosera divi nguva nenguva. Mumasystem mazhinji emagetsi, izvi zvinoitika ka50 kana ka60 pasekondi (zvinoyerwa seHertz, Hz). Izvi zvinoreva kuti maerekitironi ari muwaya yemba yako ari kudedera mberi nekudzoka ka60 pasekondi, kwete kufamba mudenderedzwa rinoenderera mberi.

2. "Hondo yeMagetsi" uye Nei AC Yakakunda paKutumira Grid

Izvi hazvisi zvenhoroondo chete; ndicho chikonzero chikuru chinoita kuti grid redu remagetsi rive rakavakirwa paAC, uye nekudaro, neimatransformer emagetsizvinotsoropodza zvikuru.

Mukupera kwezana remakore rechi19, Thomas Edison akatsigira DC, ukuwo Nikola Tesla naGeorge Westinghouse vakatsigira AC. AC yakahwina "Hondo yeMazuva Ano" nechikonzero chimwe chete chikuru:kushanduka.

Dambudziko rekutumira DC:Kana magetsi achifamba kure, anosangana ne resistance muwaya, zvichikonzera kurasikirwa kwemagetsi sekupisa. Kuti uderedze kurasikirwa uku, unofanirwa kutumira simba panguva chaiyo.voltage yakakwirauye wobva "wadzika pasi" kusvika pamagetsi akachengeteka, akaderera edzimba nemabhizinesi.

Chikanganiso Chinouraya cheDC:Mumakore ekuma1880, pakanga pasina nzira inoshanda uye isingadhuri yekuwedzera kana kuderedza voltage yeDC.

Kubudirira kweAC:Voltage yeAC inogona kuwedzerwa zviri nyore (kukwidzwa) uye kuderedzwa (kuderedzwa) uchishandisa mudziyo unonzitransformer.

Apa ndipo panopinda hunyanzvi hwedu.Matransformer emagetsiPazviteshi zvinogadzira magetsi, wedzerai voltage yeAC kusvika padanho rakakwirira zvikuru (senge 400,000 volts kana kupfuura) kuti ikwanise kutumirwa kure zvakanaka pasina kurasikirwa kukuru. Zvadaro, pazviteshi zviri pedyo nenzvimbo dzine vanhu vakawanda, mamwe ma transformer anodzikisa voltage kusvika pa120/240V yatinoshandisa mudzimba dzedu.

Kugona kuri nyore uku kushandura magetsi ndiko kwakaita kuti AC ive chiyero chisingapokane chemagetsi epasi rose.

3. Mashandisirwo Emazuva Ano: Painopenya Imwe Neimwe

Kunyange zvazvo AC ichitonga grid, DC haisi yekare zvachose. Rudzi rumwe nerumwe rune hunyanzvi hwarwo:

AC ndiyo yakanakisisa kune:

Kupa simba kumaguta ese nedzimba.

Mota dzemaindasitiri nemichinazviri nyore uye zvakavimbika paAC.

Zvishandiso zvine simba gurusekudziya nemwenje.

DC inokosha kune:

Zvemagetsi:Nhare yako, laptop, TV, uye zvishandiso zvedhijitari zvinoshanda mukati meDC. Ndosaka ma power adapters avo (kana kuti "chargers") ari ma AC-to-DC converters.

 

Mabhatiri:Mabhatiri ese (kusanganisira ari muma EV) anochengeta uye anopa simba reDC.

 

Simba rezuva:Mapaneru ezuva anogadzira magetsi eDC, izvo zvinoda inverter kuti ishandurwe kuita AC yekushandisa pamba.

 

Mota dzeMagetsi:Mabhatiri emagetsi anoshandisa DC, uye nzvimbo dzekuchaja nekukurumidza dzeDC dziri kuva tsika yakajairika.

 

Mhedziso: Kudyidzana Pamwe Chete

Musiyano uripo pakati peAC neDC hausi wekuti ndeipi iri nani; asi ndewekuti ndeipi yakakodzera basa racho. Nyika yedu yanhasi inovimba nekubatana kwakasimba pakati pezviviri izvi.

 

ACndiye shasha yekutapurirana nekugovera simba kure, inogoneswa nevaya vanozvininipisa asi vakakoshatransformer yemagetsi.

 

DCndiye shasha yekuchengetwa kwesimba uye midziyo yemagetsi yedhijitariizvo zvinopa simba kuhupenyu hwedu hwezuva nezuva.

 

PaSangano reHutano hweVeruzhinji, tiri nyanzvi mune AC divi rekubatana uku. Tinogadzira uye tinogadzira zvinhu zvakavimbikamatransformer emagetsiizvo zvinoumba musimboti wezvivakwa zvemagetsi, zvichiita kuti simba reAC rinogadzirwa pafekitori risvike zvakanaka uye zvakachengeteka pamusuwo wako.
