HVC Capacitor Film Capacitor Parameter Kufotokozera Share

Kuthekera ndiko kuyeza pafupipafupi pa 1 kHz ± 20 Hz mkati mwapang'onopang'ono komanso koyipa (ngati kuli kokulirapo kuposa 1 microfarad capacitance) Kuyesa kwake pafupipafupi ndi 120 Hz), ndipo kutentha kwake ndi 25 oc ± 5 ° C. kupatuka ndi ± 10%.

 

Dissipation Factor kapena TANσ ndi chiŵerengero cha capacitor ESR ndi momwe zimachitikira. Kuyeza pafupipafupi pa 1 kHz ± 20 Hz (Ngati ma frequency oyesera ndi 120 Hz ndi akulu kuposa 1 microfarad, kutentha kwake ndi 25 oc ± 5 ° C, Osakulirapo kuposa mtengo womwe watchulidwa.

 

Kukaniza kwa insulation kwa ma capacitor ovotera pamwamba pa 0.25 mpaka 0.5 microscope, kusintha kumadalira mankhwala (MΩ • μF) ku mtengo wochepa wotsutsa (MΩ) kuchokera ku osachepera kukana capacitor (MΩ). Pambuyo mphindi ziwiri pa 100V DC voteji ndi 25 ± 5 ° C, kukana kutchinjiriza sikungakhale kocheperako kuposa RC mankhwala kapena oveteredwa kukana mtengo.

 

Voltage yovotera ndiye voteji yopitilira muyeso pakugwiritsa ntchito kwenikweni kutentha kwambiri pakugwiritsira ntchito kwenikweni.

 

Mphamvu ya dielectric ndiye mphamvu yayikulu kwambiri yomwe capacitor imatha kupirira kutentha kwachipinda. Itha kuyezedwa pogwiritsa ntchito voliyumu ya quotation yotchulidwa ndi voliyumu ya 100 Ω kwa mphindi imodzi. Mwachitsanzo, kuti muyese capacitor yamtundu wa DPM, mtengo wake wovotera ndi 250V DC, mphamvu ya dielectric ndi 175%, ndipo mphamvu ya dielectric imafunika kuyesedwa ndi 438 V DC.

 

Mayesero a Moyo : Pa kutentha kwakukulu kwambiri ± 3 ° C, magetsi omwe amagwiritsidwa ntchito pa capacitor amagwiritsidwa ntchito pamagetsi a 500 kapena 1,000 (+72, -2) maola. Sipayenera kukhala mawonekedwe osawonongeka ndipo mtengo wa capacitance umasintha osapitilira ± 5%. The insulation resistor sitsika mpaka 50% ya malire oyamba. Kutayika kwa kutaya sikudutsa malire oyambirira.

 

Kuthekera kwa pulse  ndi kuthekera kopitilira apo. Capacitor iyi imatsimikiziridwa ndi kukhulupirika kwanthawi yomweyo, yomwe imayimiridwa ndi mtengo wovotera wa DV / DT, womwe ndi gawo lovomerezeka lakusintha kwamagetsi (gawo ndi V / μs). Pachimake chovotera panopa (AMPS) ndi chofanana ndi mtengo wa capacitor (μF) ndi DV / DT wovotera: Ipk = C(dV/dt) 

 

Kusindikiza chizindikiro potengera nambala, mtengo wa capacitance (μF), kupotoka kwa mphamvu (%), wopanga, ndi voliyumu yovoteledwa (voltage ya DC ndi AC). Ma capacitors ang'onoang'ono amatha kukhala ndi mtundu, wopanga (HVC), capacitance (PF), ndi code deviation code. Mwachitsanzo: "DLMCD" ndi "682k" amaimira DLM zitsanzo, 6800 pf (2 ndi 0), ndi 10% kulolera malire.

 

Code kugwiritsa ntchito kupatuka ndi motere:

F = ± 1%
G = ± 2%
H = ± 6%
I = ± 3%
J = ± 5%
K = ± 10%
M = ± 20%
