A liquid lead-type electrolytic capacitor imhando ye capacitor inoshandiswa zvakanyanya mumidziyo yemagetsi. Chimiro chayo chinonyanya kuumbwa nealuminium shell, electrodes, liquid electrolyte, inotungamira, uye kuisa chisimbiso zvikamu. Kuenzaniswa nedzimwe mhando dze electrolytic capacitors, liquid lead-type electrolytic capacitors ine yakasarudzika hunhu, senge yakakwira capacitance, yakanakisa frequency maitiro, uye yakaderera yakaenzana nhevedzano kuramba (ESR).
Basic Structure uye Working Principle
Iyo yemvura inotungamira-mhando electrolytic capacitor inonyanya kusanganisa anode, cathode, uye dielectric. Iyo anode inowanzo gadzirwa nepamusoro-purity aluminium, iyo inopinda anodizing kuti iite chidimbu chitete chealuminium oxide film. Iyi firimu inoshanda se dielectric ye capacitor. Iyo cathode inowanzo gadzirwa nealuminium foil uye electrolyte, ine electrolyte inoshanda sezvese zviri zviviri cathode zvinhu uye yepakati ye dielectric regeneration. Kuvapo kwe electrolyte kunobvumira capacitor kuchengetedza kushanda kwakanaka kunyange pakupisa kwakanyanya.
Iyo yekutungamirira-mhando yekugadzira inoratidza kuti iyi capacitor inobatanidza kudunhu kuburikidza nemitungamiri. Aya anotungamira anowanzo kugadzirwa netambo waya yemhangura, kuve nechokwadi chekubatana kwemagetsi panguva yekutengesa.
Hunhu Hunokosha
1. ** High Capacitance **: Liquid lead-type electrolytic capacitors inopa simba rakakwirira, zvichiita kuti zvive zvakakosha pakusefa, kubatanidza, uye kushandiswa kwekuchengetedza simba. Vanogona kupa guru capacitance mudiki vhoriyamu, iyo inonyanya kukosha munzvimbo-yakavharirwa zvigadzirwa zvemagetsi.
2. ** Low Equivalent Series Resistance (ESR) **: Kushandiswa kwe electrolyte yemvura kunoguma mu ESR yakaderera, kuderedza kurasikirwa kwesimba uye kugadzirwa kwekupisa, nokudaro kuvandudza kushanda uye kugadzikana kwe capacitor. Ichi chimiro chinovaita kuti vafarirwe mune yakakwirira-frequency switching magetsi, maodhiyo emidziyo, uye mamwe maapplication anoda yakakwira-frequency kuita.
3. **Akanaka Frequency Characteristics**: Aya ma capacitor anoratidza kushanda kwakanakisisa pamafafitera epamusoro, zvinobudirira kudzvinyirira ruzha rwepamusoro-frequency. Naizvozvo, ivo vanowanzoshandiswa mumasekete anoda kugadzikana kwepamusoro-frequency uye ruzha rwakaderera, semagetsi emagetsi nemidziyo yekutaurirana.
4. ** Upenyu Hwakareba **: Nokushandisa ma electrolyte emhando yepamusoro uye maitiro ekugadzirwa kwepamusoro, mvura inotungamira-mhando ye electrolytic capacitors inowanzova nehupenyu hurefu hwebasa. Pasi pemamiriro ekushanda akajairwa, hupenyu hwavo hunogona kusvika zviuru zvakati kusvika kumakumi ezviuru zvemaawa, zvichisangana nezvinodiwa zvezvizhinji zvekushandisa.
Nzvimbo dzekushandisa
Liquid lead-type electrolytic capacitors inoshandiswa zvakanyanya mumidziyo yakasiyana yemagetsi, kunyanya mumaseketi emagetsi, maodhiyo emidziyo, michina yekutaurirana, uye zvemagetsi zvemotokari. Iwo anowanzo shandiswa mukusefa, kubatanidza, decoupling, uye simba rekuchengetedza maseketi kusimudzira mashandiro uye kuvimbika kwemidziyo.
Muchidimbu, nekuda kwehukuru hwavo hwepamusoro, yakaderera ESR, yakanakisa frequency maitiro, uye hupenyu hurefu, mvura inotungamira-mhando ye electrolytic capacitor yave zvinhu zvakakosha mumidziyo yemagetsi. Nekufambira mberi mune tekinoroji, kuita uye kushandiswa kwemhando yeaya capacitor acharamba achiwedzera.
