1. Mubvunzo: Yongming Capacitors inoti kuramba kwayo kurira kwavandudzika kubva pa5-10g kusvika pa10-30g. "G" iyi inoreva mamiriro api chaiwo ekuyedza? Kurira kwekusarongeka here kana kuti kurira kwe sinusoidal? Ndezvipi zviyero zvekuyedza?
A: Pano, "g" zvinoreva kukurumidza kwegiravhiti, chikamu chekukurumidzisa mukuyedza kuzunungusa. Iyo 10-30g vibration resistance parameter inowanzo shandiswa pakuyedza kuzunungusa kwe sinusoidal, iyo inotevedzera kushushikana kwekufamba kwenguva nenguva kunoitika pachigadzirwa panguva yekufambisa nekushandisa. Miyero yekuyedza yechigadzirwa inotarisa zvirevo zveindasitiri zvakaita seIEC 60068-2-6 (International Electrotechnical Commission standard) kuti ive nechokwadi chekuti ine simba rekugadzira munzvimbo dzine kuzunungusa kwakanyanya.
2. Mubvunzo: Kunze kwekudzivirira kudedera, ndedzipi zvakanakira capacitor iyi yemvura zvichienzaniswa nema capacitor echip emvura akajairwa uye ma capacitor e solid-state ane zvirevo zvakafanana maererano neESR (Equivalent Series Resistance) uye kugona kweripple current?
A: Zvichienzaniswa nema capacitor emvura akajairika, chigadzirwa ichi, kuburikidza ne optimized electrode foil uye electrolyte formulation, chinoratidza ESR yakaderera uye ripple current yakakwira pamusoro pekupisa kwakakura kubva -40°C kusvika +105°C/125°C. Izvi zvakakosha pakubata ma current pulses makuru muma electronic control systems. Zvichienzaniswa nema capacitor e solid-state, zvinopa kushanda zvakanaka pamutengo wepamusoro uye ma voltage ratings akakwira, uye zvinodzivirira DC bias characteristics yema solid-state capacitors, zvichikonzera capacitance yakagadzikana nekuchinja kwe voltage.
3. Mubvunzo: Tembiricha yekushanda kwechigadzirwa ichi ndeyei? Kunyanya munzvimbo dzakakwirira uye dzakaderera dzinogona kusangana nendege dzakaderera, mashandiro e capacitor patembiricha yakaderera (semuenzaniso, ESR inochinja pa -40°C)?
A: Tembiricha yekushanda kwechigadzirwa ichi iri pakati pe -40°C kusvika +105°C, nemamwe mamodheru achisvika +125°C. Kune nzvimbo dzakakwirira uye dzine tembiricha yakaderera, takagadzirisa electrolyte kuti tive nechokwadi chekuti kuwedzera kweESR kunoramba kuri mukati mehuwandu hunogona kudzorwa patembiricha yakaderera ye -40°C, zvichivimbisa kugadzikana kwesystem panguva yekutanga kutonhora uye kushanda kwetembiricha yakaderera.
4. Mubvunzo: Chii chaizvo chiri chimiro che "mount-mount" capacitor? Inobatsira sei pakuvandudza resistance ye vibration? Inowanikwa here kuburikidza ne special potting compound, base mechanical structure, kana lead frame design?
A: Capacitor ye "mount-mount" inoreva package ye capacitor core yakaiswa zvakachengeteka pachigadziko chesimbi kana resin, uye yozoiswa pamusoro (SMT) kuburikidza nemapadhi ari pachigadziko. Kudzivirirwa kwekudzvinyirirwa kwakavandudzwa kunonyanya kutsamira pane: 1) chimiro chakasimba chechigadziko chinoparadzira kudzvinyirirwa kubva kuPCB kuenda kuchigadziko chose; 2) kugadzika kwakasimba kwepakeji yemukati mepakati kudzivirira kufamba kwemagetsi emukati; uye 3) potting compound inoshanda zvakanyanya kuti iwedzere kuvharidzira uye kunwisa simba rekudzvinyirirwa. Dhizaini iyi ine mativi matatu pamwe chete inoita danho rakakura mukudzivirira kudzvinyirirwa.
5. Mubvunzo: Matambudziko api anosangana nema capacitor mumadhiraivha emvura/oiri mumasystem ekutonga kupisa kwemotokari (senge tembiricha yakakwira uye simba guru remvura)? Yung-Ming anogadzirisa sei matambudziko aya?
A: Ma capacitor ari mumadhiraivha emvura/oiri anowanzo shandiswa kusefa uye kuvharidzira inverter output, akatarisana nema ripple currents makuru anokonzerwa ne high-frequency switching, high engine compartment tembiricha, uye engine vibration pachayo. Zvigadzirwa zvedu, zvine high ripple current potential, high tembiricha rating ye105°C/125°C, uye shock resistance ye10-30g, zvinogona kushanda zvakadzikama munzvimbo dzakaoma kudaro, zvichiona kururama uye kuvimbika kwemota.
6: Mubvunzo: Mumasystem akakosha pakuchengetedza akadai seElectric Power Steering (EPS), ndeapi maitiro emakapicha anokundikana? Yongming inobatsira sei kudzivirira kutadza kunouraya senge mashort circuits uye open circuits?
A: MuEPS, kukundikana kwe capacitor (kunyanya mashort circuits) kunogona kukonzera kuomarara kwesystem. Tinovandudza kuvimbika kuburikidza nenzira dzinotevera: 1) Kushandisa zvinhu zvakachena zvakanyanya uye kudzora maitiro akasimba kuderedza kusvibiswa kwemukati; 2) Dhizaini yevharuvhu isingaputike (kunyangwe iri mhando yekuisa pamusoro, ine nzira yekuderedza kumanikidzwa muchimiro chayo); 3) 100% surge current uye inotsungirira kuyedzwa kwevoltage kubvisa kukundikana kwekutanga. Uyezve, kuramba kwayo kwakanaka kweshock kunodzivirira zvakananga kutyoka kwemukati (mashort circuits) kana mashort circuits anokonzerwa nekudengenyeka.
7: Mubvunzo: Muhurongwa hwekudzora kubhururuka kwendege dziri mudenga rakaderera, basa guru rema capacitor nderei? Anoshandiswa pakusefa simba, kuchengetedza simba, kana kubatanidza masaini here?
A: Inonyanya kushandiswa mumaseketi emagetsi emakomputa ekutonga ndege nemadhiraivha emota dzeservo, inoshanda semutongi wemagetsi, sefa, uye inopa magetsi ekukurumidza kutenderera. Masisitimu ekudzora ndege ane zvinodiwa zvakanyanya zvekuchena kwemagetsi uye mhinduro yekukurumidza; kushanda kwakagadzikana kwecapacitor kwakakosha pakuona kuti data remasensa rakarurama uye mhinduro yeservo inokurumidza.
8: Mubvunzo: Kutenderera kwemhepo kunokonzerwa nekuchinja kwemhepo kunoitika mundege kwakaoma. Chigadzirwa ichi chakagadziridzwa here kuti chikwanise kutenderera mune imwe frequency range (semuenzaniso, 50Hz-2000Hz)?
A: Ehe, bvunzo yedu yekubvunda inovhara huwandu hwemafrequency akajairwa (semuenzaniso, 10Hz kusvika 2000Hz), tichinyanya kutarisa mafrequency epakati kusvika akakwira ane chekuita nemagetsi anowanzo shandiswa (semuenzaniso, mota, mapropeller). Kuburikidza nekugadzirwa kwechimiro, mafrequency ayo anonzwika anodzivirira mafrequency aya akakosha, nokudaro achichengetedza mashandiro munzvimbo dzakaoma dzekudengenyeka.
9: Mubvunzo: Ndege dziri mudenga rakaderera dzinonzwa huremu zvakanyanya. Iyi capacitor inokwanisa sei kudzivirira kutenderera kwakanyanya uku ichidzora huremu hwayo nehukuru hwayo? Pane dhizaini yakareruka here?
A: Tinoenzanisa simba rekudzivirira kudzungunyika nekuita kuti zvinhu zvidiki zvisashande panguva yekugadzira. Nekushandisa foil yemagetsi ine simba rakawanda kuderedza huwandu hwepakeji yepakati kuti ive nesimba rakafanana, uye nekuvandudza huwandu hwezvinhu zvepasi nezvinovharwa, uku tichisangana ne10-30g shock resistance rating, huwandu hwayo nehuremu zvinoramba zviri padanho rakafanana nezvigadzirwa zvemazuva ano zvemhando imwe chete, zvichisangana nezvinodiwa zvendege zviri nyore.
10Q: Kana tichienzanisa nema capacitor akasimba, ma capacitor emvura anowanzova nehupenyu hushoma (kuoma kwe electrolyte). Yung-Ming anoderedza sei dambudziko iri?
A: Tinowedzera hupenyu hwezuva nezuva kuburikidza nematekinoroji maviri akakosha: 1) kushandisa electrolyte ine simba rakawanda remagetsi uye kumanikidzwa kwakaderera kwemhepo kuti tideredze kurasikirwa nekubuda kwemvura pakupisa kwakanyanya; 2) kushandisa chivharo cherabha chinovhara simba repamusoro kuti tideredze kupenya kwemagetsi. Izvi zvinowedzera hupenyu hwema capacitor edu emvura pakupisa kwakanyanya.
