Mphamvu ya Mphamvu Pamiyendo ya LED

Mphamvu yamphamvu ndi gawo lofunikira la nyali za adatsogolera, ziribe kanthuNyali Yobwezeretsedwansokapena nyali zouma. Chifukwa chake timvetsetsenso kuti chinthu champhamvu ndi chiyani.

1, mphamvu
Mphamvu zamphamvu zimadziwika kutiAddlempkutulutsa mphamvu yogwira. Mphamvu ndi muyeso wa mphamvu zomasulira, ndipo mu masitepe a DC ndizomwe zimapangidwa ndi magetsi v ndi pano A. Kusiyana kwa mphamvu yooneka ndi mphamvu zenizeni kumabweretsa mphamvu, ndipo mphamvu zake ndizofanana ndi kuchuluka kwa mphamvu zenizeni kuti zidziwike. Chifukwa chake mphamvu zenizeni mu ma AC ndizofanana ndi kuchuluka kwamphamvu kwambiri mphamvu.
Izi ndi: Mphamvu zolimbitsa thupi = mphamvu zenizeni / zowoneka bwino. Mphamvu yokhayo yomwe imakhala ndi chitsime chamagetsi monga 1. Kusiyana pakati pa mphamvu yeniyeni ndi mphamvu yokwanira pakati pa zida zowopsa monga nyali ndizambiri.

2, mphamvu zowoneka
Mphamvu yogwira: Chithandizo cha magetsi a ma ac ndi ma ac pano. Ndi formula monga: S = UI. Momwe S imavotera mphamvu zotulutsa ku VA (Valt-AMPre); Uvota volid ku V, monga 220v, 380v, etc.; Ndimavotera zomwe zilipo mu A. Mphamvu yomwe ikuwoneka kuti ili ndi magawo awiri: Mphamvu yogwira (p) ndi mphamvu yogwira (Q). Mphamvu yogwira imatanthauza gawo la ntchito yomwe yachitika mwachindunji. Mwachitsanzo, kuwalako, kuzungulira kwamagalimoto, dera lamagetsi kugwira ntchito. Chifukwa mphamvu iyi yakhala kutentha, imatha kumverera mwachindunji ndi anthu, kotero anthu ena ali ndi chinyengo, ndiye mphamvu yogwira ntchito ngati mphamvu yowonekayo, omwe amadziwa kuti mphamvu yogwira ntchito ndi imodzi yokha
Mphamvu zowoneka bwino, ndi formula: p = scos θ = uicosθ = uif. Komwe p ndi mphamvu yogwira mu W (Watts); F = cos θ imatchedwa mphamvu, ndipo θ ndi njira yosiyana ndi magetsi osiyanasiyana osagwirizana. Mphamvu zopangidwa ndi gawo la mphamvu zosungidwa mdera koma osagwira ntchito mwachindunji, zofotokozedwa ndi formula: q = ssin θ = Usinθ. Komwe q ndi mphamvu yogwira ntchito var (kusowa).

WaA StudlampsNdipo mabwalo ena onse amagetsi omwe amagwira ntchito pa DC Voyeti, ndizosatheka kugwira ntchito popanda mphamvu.
