HVC Capacitor Film Capacitor Siffar Siga Share

Capacitance shine auna mitar a 1 kHz ± 20 Hz a cikin madaidaicin madaidaici da mara kyau (idan ya fi ƙarfin 1 microfarad capacitance) Mitar gwajin sa shine 120 Hz), kuma ma'aunin zafin jiki shine 25 oc ± 5 ° C. Ma'auni karkacewa shine ± 10%.

 

Factor Dissipation Factor ko TANσ shine rabon capacitor ESR da amsawar sa. Mitar aunawa a 1 kHz ± 20 Hz (Idan mitar gwajin ita ce 120 Hz ya fi 1 microfarad, ma'aunin zafin jiki shine 25 oc ± 5 ° C, Bai fi girma da ƙayyadadden ƙimar ba.

 

Juriya na insulation don masu iya ƙididdigewa sama da 0.25 zuwa 0.5 microscopy, canjin ya dogara da samfurin (MΩ • μF) zuwa ƙimar juriya mafi ƙarancin (MΩ) daga ƙaramin ƙarfin juriya (MΩ). Bayan mintuna biyu a ƙarfin wutar lantarki na 100V DC da 25 ± 5 ° C, juriya na rufi ba zai iya zama ƙasa da samfurin RC ba ko ƙimar juriya mai ƙima.

 

Ƙididdigar wutar lantarki shine matsakaicin ci gaba da ƙarfin lantarki a ainihin amfani da matsakaicin zafin aiki a ainihin amfani.

 

Ƙarfin dielectric shine matsakaicin matsakaicin ƙarfin wutar lantarki wanda capacitor zai iya ɗauka a ƙimar zafin ɗakin. Ana iya auna shi ta hanyar amfani da ƙimar ƙarfin magana da aka ƙayyade ta ƙarfin lantarki na 100 Ω na minti ɗaya. Misali, don auna ma'aunin capacitor nau'in DPM, ƙimar ƙarfin lantarkin da aka ƙididdige shi shine 250V DC, ƙarfin dielectric shine 175%, kuma ƙarfin dielectric ana buƙatar gwadawa ta 438V DC.

 

Gwajin Rayuwa : A mafi girman ƙimar zafin jiki ± 3 ° C, ƙarfin lantarki da ake amfani da shi akan capacitor ana amfani da wutar lantarki na sa'o'i 500 ko 1,000 (+72, -2). Dole ne babu bayyanar ba tare da lalacewa ba kuma ƙimar capacitance ta canza ba fiye da ± 5%. Mai hana insulation baya faɗuwa zuwa 50% na iyakar farko. Asarar asarar baya wuce iyakar farko.

 

Ƙarfin bugun jini  shine mafi girman ƙarfin halin yanzu. An ƙayyade wannan capacitor ta hanyar amincin yanayin halin yanzu, wanda ke wakilta ta ƙimar ƙimar DV/DT, wanda shine madaidaicin ƙimar canjin ƙarfin lantarki (naúrar V / μs). Ƙimar ƙoƙon da aka ƙididdige na yanzu (AMPS) daidai yake da samfur na ƙimar ƙimar capacitor (μF) da ƙimar ƙimar DV/DT: Ipk = C (dV/dt) 

 

Buga alama ta lamba, ƙimar ƙarfin ƙarfi (μF), rarrabuwar ƙarfi (%), mai samarwa, da ƙimar ƙarfin lantarki (DC da AC ƙarfin lantarki). Ƙananan ma'auni na iya samun nau'i kawai, mai samarwa (HVC), capacitance (PF), da lambar karkacewar ƙarfin. Misali: "DLMCD" da "682k" suna wakiltar ƙirar DLM, 6800 PF (2 shine 0), da iyakacin haƙuri 10%.
