Kusiyana pakati high frequency equipment uye magetsi frequency muchina

High-frequency midziyo inoshandisa yakakwirira-frequency switching tekinoroji kutsiva iyo UPS yemagetsi frequency transformers mune rectifiers uye inverters ine high-frequency switching elements, inowanzozivikanwa semichina yepamusoro-frequency. High-frequency michina idiki muhukuru uye yakakwirira mukubudirira. Simba frequency muchina: UPS inoshandisa simba frequency transformer seinogadzirisa uye inverter zvikamu zvinowanzozivikanwa semagetsi frequency muchina. , Muchina wepamusoro-frequency hauna shanduri yekuzviparadzanisa, uye mutsara wayo zero une high-frequency current, kunyanya kubva pakukanganiswa kweharmonic yegridi yemagetsi, iyo inoputika yeUPS rectifier uye high-frequency inverter, uye harmonic kupindira kwemutoro, etc. The kupindira voltage haisi chete Values ​​yakakwirira uye yakaoma kubvisa. Nekudaro, iyo yakabuda zero-pasi voltage yemagetsi frequency muchina yakaderera, uye hapana yakakwira-frequency chikamu, iyo inonyanya kukosha kune yekutaurirana kuchengetedzwa kwekombuta network. Iyo yakabuda yemuchina wepamusoro-frequency haina kuparadzaniswa ne transformer. Kana iyo inverter simba mudziyo ipfupi-inotenderera, iyo yakakwira DC voltage paDC bhazi (DC BUS) inoiswa zvakananga kumutoro, inova njodzi yekuchengetedza, asi magetsi frequency muchina hauna dambudziko iri. Iyo magetsi frequency muchina ine yakasimba anti-mutoro kukanganisa kugona.

High-frequency midziyo inoreva muchina weX-ray une high-voltage jenareta inoshanda frequency yakakura kupfuura 20kHz, uye muchina wemagetsi frequency unoreva muchina weX-ray une high-voltage jenareta inoshanda isingasviki 400Hz. Muchina wemagetsi wemagetsi une 100Hz sine ripple mushure meiyo 50Hz magetsi frequency emagetsi yasimudzwa nekugadziriswa. Mushure mekusefa, kuchine zvinopfuura gumi muzana zveripple. Iyo yakakwira frequency muchina ine yakakwira yekushanda frequency, uye voltage mushure mepamusoro voltage rectification inongogara iri DC, ripple inogona kunge isingasviki 10%. Akasiyana-siyana high-voltage voltages anowirirana nemagetsi emagetsi emasimba akasiyana, nekudaro achigadzira X-rays yewavelengths akasiyana. Iyo yakawanda yeX-ray spectrum ndeye, zvishoma kupararira, uye kujeka kwekufungidzira. Iyo inobuda mutsara wemagetsi emagetsi frequency muchina wakaoma, huwandu hweX-rays pahunhu frequency panguva imwechete idiki, mitsara yakapararira mitsetse yakawanda, uye kufungidzira kwakasvibiswa. Muchina wepamusoro-frequency une nyore kubuda spectrum, mitsetse isina kurasika yakapararira, kufungidzira kwakajeka, uye inoderedza huwandu hwese hunobuda mutsetse neinopfuura 0.1% zvichienzaniswa nemagetsi frequency muchina.
