Isho ukuthini iMv kugesi?
Okuqukethwe
Njengochwepheshe kagesi ofundisa abafundi abambalwa, ngibona abantu abaningi bedidekile lapho bebona igama elithi "MV" nokuthi lisho ukuthini endaweni kagesi. Njengoba kungasho izinto ezimbalwa, ngizobheka ngayinye yazo ngezansi.
I-MV ingamela enye yezinto ezintathu kugesi.
- I-Megavolt
- I-voltage emaphakathi
- I-Milivolt
Ngezansi ngizochaza kabanzi ngezincazelo ezintathu futhi nginikeze izibonelo zokusebenzisa kwazo.
1. I-Megavolt
Iyini iMegavolt?
I-megavolt, noma i-“MV,” ingamandla inhlayiyana eshajwe nge-electron eyodwa ewatholayo lapho idlula umehluko ongaba khona wamavolthi ayisigidi endaweni engenalutho.
Sebenzisa i-megavolt
Zisetshenziswa kwezokwelapha ekwelapheni umdlavuza, ama-neoplasms kanye nezimila ngokwelashwa kwangaphandle kwe-radiation. Izazi ze-radiation oncologists zisebenzisa imishayo ene-voltage range ye-4 kuya ku-25 MV ukwelapha umdlavuza ekujuleni komzimba. Lokhu kungenxa yokuthi le misebe ifinyelela kahle ezindaweni ezijulile zomzimba.
Ama-X-ray e-Megavolt angcono ekwelapheni izimila ezihlala phansi ngenxa yokuthi alahlekelwa amandla amancane kunama-photon angenawo amandla amancane futhi angangena ajule emzimbeni ngomthamo wesikhumba ophansi.
I-Megavolt X-ray nayo ayizilungele izinto eziphilayo njenge-orthovoltage X-rays. Ngenxa yalezi zimfanelo, ama-megavolt x-reyi ngokuvamile angamandla asetshenziswa kakhulu kumasu esimanje okwelapha nge-radiotherapy njenge-IMRT.
2. I-voltage emaphakathi
Iyini i-Medium Voltage?
Ezimweni eziningi, "i-medium voltage" (MV) ibhekisela kumasistimu okusabalalisa angaphezu kuka-1 kV futhi ngokuvamile afika ku-52 kV. Ngenxa yezizathu zobuchwepheshe nezomnotho, amandla kagesi okusebenza amanethiwekhi okusabalalisa amandla kagesi aphakathi nendawo avamile ukuba eqe ku-35 kV.
Ukusetshenziswa kwe-voltage ephakathi
Amandla kagesi amaphakathi anokusetshenziswa okuningi futhi inombolo izokhula kuphela. Esikhathini esidlule, ama-voltage esigaba samandla kagesi aphakathi ayesetshenziswa kakhulu ekudluliselweni kwesibili nasekusabalaliseni okuyinhloko.
Amandla kagesi aphakathi nendawo ngokuvamile asetshenziselwa ukunika amandla ama-transformer asabalalisa ehlisa i-voltage ephakathi ukuya ku-voltage ephansi kumishini yamandla ekugcineni komugqa. Ngaphezu kwalokho, isetshenziswa kabanzi embonini yamamotho ane-voltage engu-13800V noma ngaphansi.
Kodwa i-topology yesistimu entsha kanye nama-semiconductors akwenze kwaba nokwenzeka ukusebenzisa amandla kagesi kumanethiwekhi kagesi aphakathi. Ngaphezu kwalokho, amanethiwekhi amasha okusabalalisa akhiwe eduze kwe-voltage emaphakathi AC noma i-DC ukuze enze indawo yemithombo yamandla emisha nabasebenzisi.
3. Ama-Milivolts
Yini ama-millivolts?
I-Millivolt iyunithi yamandla kagesi namandla e-electromotive ku-International System of Units (SI). I-Millivolt ibhalwe njenge-mV.
Iyunithi eyisisekelo yama-millivolts yi-volt, futhi isiqalo sithi "milli". Isiqalo esithi milli sivela egameni lesiLatini elisho "inkulungwane". Ibhalwe ngokuthi m. Milli ingxenye yenkulungwane (1/1000), ngakho ivolthi eyodwa ilingana namamilivolthi angu-1,000.
Ukusetshenziswa kwe-Millivolt
Ama-Millivolts (mV) amayunithi asetshenziselwa ukukala amandla kagesi kumasekhethi kagesi. Ilingana no-1/1,000 volts noma 0.001 volts. Le yunithi yaqanjwa ukuze kube lula ukulinganisa nokunciphisa ukudideka phakathi kwabafundi. Ngakho-ke, leli bhulokhi alivamile ukusetshenziswa emkhakheni we-electronics.
I-millivolt iyinkulungwane yevolthi. Isetshenziselwa ukukala ama-voltages amancane kakhulu. Lokhu kungaba usizo kakhulu lapho udala amasekhethi kagesi lapho ama-voltage amancane angaba nzima kakhulu ukukala.
Ukufingqa
Ugesi uyinkambu eyinkimbinkimbi futhi ehlala ishintsha. Ngethemba ukuthi lesi sihloko sisizile ukuphendula noma yimiphi imibuzo mayelana nokuthi iMv imeleni kugesi.
