無功電力的意思、翻譯和例句

是什麼意思

「無功電力」是指在電力系統中,並不直接做功的電力。這種電力通常在交流電系統中出現,主要用於維持電壓水平和支持電氣設備的正常運行。無功電力不轉換為有用的能量,但對於穩定電力系統和確保電氣設備的運行至關重要。無功電力的單位是乏(VAR),與有功電力(瓦特)相對。

1:Reactive Power

用法:

在交流電系統中,無功電力通常被稱為反應電力,這是因為它與電流和電壓之間的相位差有關。反應電力在感性負載(如電動機和變壓器)中發揮重要作用,幫助它們正常運行。雖然反應電力不做實際的功,但卻是保持系統穩定所必需的。

例句 1:

反應電力對於電動機的運行至關重要。

Reactive power is essential for the operation of motors.

例句 2:

電力公司需要管理反應電力以保持系統穩定。

Power companies need to manage reactive power to maintain system stability.

例句 3:

在設計電力系統時,必須考慮反應電力的需求。

When designing power systems, the demand for reactive power must be considered.

2:Non-working Power

用法:

這個術語通常用來強調無功電力不直接轉換為有用的能量。雖然它不進行實際的工作,但仍然在電力系統中扮演著關鍵角色,確保設備的正常運行。
