用電量計算

2009-02-08 7:56 am
220 V, 60 Hz
220 V, 50 Hz
請問以上電個分別用電量係幾多?

220V,60 Hz & 220V,50 Hz 係電源電壓同頻率,上面既魚缸過濾泵適合用電源 220V,60 Hz,據我所學到既 220V,60 Hz 電感電器唔適合用在 220V,50 Hz 電源上,因爲頻率唔夠高就等於係用在直流電上,轉數慢係其一,電流大係其二,魚缸過濾泵發熱係其三,仲有好多問題既講都唔曬啦。

除非標明220V 50 / 60Hz ,就適合 用在 220V 50 / 60 Hz 電源上。

用電量應該係 指功率 或 電荷(庫侖), 係取決於 負載,應該唔係電源的

220V 係 50Hz,60Hz 係 110V 用架。
