Ndeipi saizi yefuse ye1000W amplifier (yakadzama)

Iwe unogamuchira dziviriro inopiwa nefiyuzi yemagetsi chete kana chiyero ichienderana nedunhu kana wiring system iyo yakaiswa.

Kana chiyero ichi chakakwira kupfuura chinodiwa, unowana kukuvadzwa kwakanyanya kune vatauri vako, uye kana kwadzikira, unopwanya zvachose fuse waya uye odhiyo system wedunhu. 

Ramba uchiverenga kuti uwane iyo fuse ratings yaunoda kuisa kuchengetedza yako 1000W amplifier mumotokari yako kana kumba.

Ngatitangei.

Chii chinonzi fuse size ye1000W amplifier?

Kune iyo 1000 watt audio amplifier mumotokari yako, iwe unozoda fuse inosvika makumi masere amps kuti uichengetedze nemazvo. Chiyero ichi chinowanikwa kubva kune formula I = P / V, iyo inofunga nezveyero yesimba yeamplifier, simba rekubuda realternator yemotokari, uye kirasi inoshanda yeamplifier.

Kunyangwe iyo mota odhiyo amplifier inowanzouya neiyo yemukati fuse kuti idzivirire kubva pakukwira kwemagetsi, dziviriro iyi haipfuuriri kune yekunze wiring yevatauri uye iyo yese audio system.

Izvi zvinoreva kuti iwe uchiri kuda fiyuzi yemagetsi kuchengetedza yako yese amplifier system uye wiring kana paine simba rekuvhiya.

Kazhinji, kusarudza fiyuzi yemagetsi nyowani kunofanirwa kuve yakatwasuka. Iwe unongotora imwe ine muenzaniso wakafanana uye chiyero sebhokisi rekare rakaputika fuse.

Nekudaro, izvi zvinova zvakaoma kana iwe usina chero chiratidzo chechiyero kana iwe uri kuisa amplifier nyowani mumotokari yako.

Kuti ikubatsire kunyatsonzwisisa kuti ungakura sei fiyuzi yemagetsi nenzira kwayo, tichatsanangura kuti zvinhu zvitatu zvataurwa pamusoro apa ndezvipi. Isu tinokuratidza zvakare nzvimbo yavo mune yakaratidzwa fomula.

Amplifier simba rating uye kirasi inoshanda

Simba reaudio amplifier isimba rekubuda iro rinoburitsa kana richishanda. Paunotarisa mota yako amplifier, unoona iyo wattage rating mune iyo specs. Kwatiri isu, isu tinotarisira kuona 1000W spec. Iye zvino pane zvimwe zvinhu zvokufunga nezvazvo.

Audio amplifiers kazhinji inowira mumakirasi akasiyana, uye makirasi aya anoratidzirwa neakasiyana mazinga ekushanda mukushanda. Chiyero chekushanda cheamplifier huwandu hwesimba rainopenya mumawatts kana ichienzaniswa nesimba rayo rekuisa.

Iwo anonyanya kufarirwa odhiyo amplifier makirasi uye iwo akasiyana maitiro ekuita akanyorwa pazasi:

• Kirasi A - kunyatsoshanda 30%
• Kirasi B - 50% kunyatsoshanda
• Kirasi AB - kunyatsoshanda 50-60%
• Kirasi C - 100% kunyatsoshanda
• Kirasi D - 80% kunyatsoshanda

Iwe unotanga watora aya maitiro ekuita muaccount paunenge uchiverenga iro chairo simba kana kukosha kwesimba kuti upinde mufomula. Unoashandisa sei?

Kirasi A amplifiers anowanzo kushandiswa mumaseketi emagetsi mashoma nekuda kwekusashanda kwawo. Izvi zvinoreva kuti hauwanzovaona pa1000 watt masisitimu.

Iwe uchanyanya kunge uchibata nekirasi AB, kirasi C uye kirasi D amplifiers nekuda kwekuita kwavo kwepamusoro uye kuchengetedzeka mu1000 watt masisitimu.

Semuenzaniso, kune 1000 watt kirasi D yuniti ine 80% kunyatsoshanda, yako amplifier yekutanga yekuisa simba inokwira kusvika ku1250 watts (1000 watts / 80%). Izvi zvinoreva kuti kukosha kwesimba kwaunopinda mufomula ndeye 1250W, kwete 1000W.

Mushure meizvozvo, unochengeta 1000 watts ekirasi C amps uye anenge 1660 watts ekirasi AB amps.

Jenereta yakabuda

Kana isu tichiverenga chiyero chefuse yeamplifiers, isu tiri kuverenga ikozvino kana ikozvino kutumirwa nemagetsi ayo. Panyaya yemotokari amplifier, isu tiri kufunga nezvezvino zvinopihwa nealternator.

Mukuwedzera, zviyero zvemafusi emagetsi zvinogara zvichiratidzwa mune amperage. Kana iwe ukaona chiyero che "70" pane fuse, zvinoreva kuti yakayerwa pa70 amps. Sezvo maitiro emagetsi evatauri anowanzo ari masimba emagetsi, fomula inobatsira kuita shanduko dzakakodzera. 

A 1000W amplifier inogara ichimhanyisa 1000W alternator, saka isu tinovavarira kushandura iro simba kuita amps. Apa ndipo panopinda formula.

Iyo yakakosha formula yekushandura watts kuita amps ndeiyi inotevera:

Ampere = W/Volt or I=P/V uko "Ini" iri amp, "P" isimba, uye "V" iri voltage.

Kusarudza iyo voltage inopihwa nealternator haina kuoma, sezvo ichiwanzo kunyorwa pane alternator yakatarwa. Paavhareji, kukosha uku kunobva ku13.8 V kusvika ku14.4 V, uye iyo yekupedzisira ichinyanya kuwanda. Zvadaro, mune fomula, iwe unochengeta 14.4V seyakajairika voltage kukosha.

Kana iwe uchida kuve wakarurama mukufungidzira kwako, unogona kushandisa multimeter kutarisa jenareta rekupa voltage. Nhungamiro yedu yekuongorora jenareta ine multimeter inobatsira neizvi.

Mienzaniso yeFuse Ratings yeAmplifaya Simba uye Kirasi 

Nezvese zviri kutaurwa, kana iwe uchida kuwana yakakurudzirwa chiyero cheamp, unofanira kutanga wafunga kirasi uye kushanda kwayo. Iwe unoisa ichi chinoshanda chinhu kuti uwane simba rekutanga rekuisa amplifier, wozoishandura kuita maamps kuti uone kuti inguvai yakachengeteka kudhirowa.

1000 watt kirasi AB amplifier

Iine 1000 watt kirasi AB amplifier iwe unowana yekutanga yekuisa simba iri kutenderera 1660 watts uchifunga nezve 60% kushanda kwayo (1000 watts / 0.6). Wobva washandisa formula:

Ini = 1660/14.4 = 115A

Saizi yefuse yaunoshandisa yekirasi AB amplifiers ichave padyo neichi kukosha. Iyi i 110 amp fuse.

1000 watt kirasi C amplifier

Pa100% kushanda zvakanaka, unowana simba rakafanana rekubuda kubva kuClass C amplifiers sesimba ravo rekuisa. Izvi zvinoreva kuti "P" icharamba iri pa1000 watts. Ipapo iyo formula inoita seizvi:

Ini = 1000/14.4 = 69.4A

Nekutenderedza kukosha uku kune iri padyo kukosha iripo, iwe unosarudza 70 amp fuse.

1000 watt kirasi D amplifier

Nekugona kwe80%, 1000 watt kirasi D amplifiers anotanga ne1,250 watts (1000 watts/0.8). Iwe wobva waverenga chiyero uchishandisa aya maitiro mune fomula:

Ini = 1250/14.4 = 86.8A

Uri kutsvaga fuse yemota ye90A.

Zvakadini nemafusi akakura akasiyana?

500W kirasi D amplifier

Kune 500-watt amplifier, nheyo dzinoramba dzakafanana. Panzvimbo pekushandisa 500 watts mune fomula, iwe uri kufunga kugona kwekirasi. Muchiitiko ichi, 80% kunyatsoshanda zvinoreva kuti uri kushandisa 625W pachinzvimbo. Kuti uverenge chiyero chako, iwe wobva wadyisa izvi zvakakosha kuita fomula.

Ini = 625/14.4 = 43.4A

Kutenderedza iyo kusvika kune iri padyo chiyero chiripo, uri kutsvaga 45 amp fuse.

1000 W kirasi D fuse mu 120 V maseketi

Kana iyo amplifier yaunoda kuisa fuse ichishandiswa mumba mako kwete mumotokari yako, magetsi eAC pairi anowanzo kuve 120V kana 240V. Pamagetsi e120V, unoshandisa zvakakosha:

I = 1250/120 = 10.4 A. Izvi zvinoreva kuti uri kusarudza 10 amp fuse.

Kune 240 V magetsi ekushandisa, inotevera fomula inoshanda pachinzvimbo:

I \u1250d 240/5.2 \u5d XNUMX A. Unotenderedza nhamba iyi kusvika pachiyero chiri pedyo, kureva kuti, unosarudza fiyuzi yeXNUMXA.

Nekudaro, mukuwedzera kune zvese izvi, pane chimwezve chinhu chekufunga nezvacho kana uchisarudza iyo fuse ikozvino chiyero zvakachengeteka.

Zvinhu Zvinokanganisa Fuse Rating

Pane zvinhu zvakawanda zvinosanganisirwa mukuyera fuse, uye ivo vanoita kuti base rating ikwire kana kudzikira pane inotarwa neformula.

Zvimwe zvezvinhu izvi zvinosanganisira kunzwisiswa kwemudziyo unodzivirirwa nefuse, masisitimu emhepo anofefetera aripo, uye kuti tambo dzekubatanidza dzinosangana sei.

Paunenge uchisarudza fuse, iwe unofanirwa zvakare kufunga nezvayo voltage chiyero, yakakura pfupi-yedunhu ikozvino, uye saizi yemuviri. Mhando yefuse inoshandiswa mudunhu inonyanya kutarisisa zvinhu zvinofanirwa kutariswa.

Mune mota amps, unoshandisa mota blade fuse, nepo cartridge fuse inowanikwa mumidziyo yako yepamba.

Zvino, pakusarudza chiyero chefuse, pane chinhu chimwe chakakosha chekuteerera. Iyi inyaya yekuyera fuse.

Fuse derating

Derating inoitika kana iyo yakakurudzirwa fuse rating inoshandurwa kudzivirira kuvhuvhuta kusingadiwe. Kupisa kwenzvimbo yauri kuda kushandisa fuse chinhu chakakosha chinokanganisa chiyero chekupedzisira chefuse.

Iyo yakajairwa fusible waya yekuyedza tembiricha i25°C, iyo inobvisa fuse ne25% kubva pazviyero zvadzo. Panzvimbo pekushandisa 70A fuse yeClass C amplifier, unosarudza fuse ine 25% yepamusoro.

Izvi zvinoreva kuti uri kushandisa 90A fuse. Kupararira uku kunogona kuve kwakakwira kana kuderera zvichienderana nezvimwe zvinhu zvataurwa pamusoro apa.

Inowanzobvunzwa Mibvunzo

I1000 watt amplifier inotora maamps mangani?

Izvo zvinoenderana neiyo voltage iyo amplifier iri kushanda nayo. Iyo 1000W amplifier inoshandisa 8.3 amps kana ichishanda munharaunda ye120V, 4.5 amps kana ichishanda munharaunda ye220V, uye 83 amps kana ichishanda munharaunda ye12V.

Ndeipi saizi yefuse yandinoda ye1200W?

Pa1200 watts, unoshandisa 10 amp fuse mu 120 volt circuit, 5 amp fuse mu 240 volt circuit, uye 100 amp fuse mu 12 volt circuit. Dzinosiyana zvichienderana nehuwandu hwekuderera kunodiwa.
