2024年12月26日 · (metrology) Symbol for kilovolt, an SI unit of electromotive force equal to 10 3 volts.

A kilovolt is a unit of electric potential and electromotive force in the International System of Units (SI). The symbol for kilovolt is kV. The base unit for a kilovolt is volt and the prefix is kilo. The prefix kilo is derived from the Greek chilioi meaning thousand and is symbolized as k.

The units and symbols listed throughout this booklet conform to the recommendations of the International Electrotechnical Commission (IEC) and the British Standards Institution (BSI). Additionally, because of their common usage, in the Logic Symbols under Section 12 some distinctive-shape binary logic symbols have been used.

千伏是电压单位伏特 (V) 的倍数。 国际单位制 (SI) 将前缀千 (k) 定义为一千倍数。

如A、V、W、kV、kW、kVA、kvar、lx、km等应一律使用法定计量单位，特别要注意单位符号字母的大小写要正确，凡由人名转化来的单位符号 如A、V、W、N、Pa 和兆以上的词头符号 如M、G均应大写；除此之外，则一律小写，如kV、MW、kvar、km等。

2023年5月9日 · 电压（Voltage）是指电场中两点间的电势差，通常用符号V表示，单位为伏特（Volt，简写V）。 而在描述高压电网和输电线路时，电压的单位一般为千伏（kV），但是其中的“k”却通常用小写字母表示，这是因为在国际单位制中，“k”代表千（kilo），而“K”则代表开尔文（Kelvin）。 本文将从历史、规范和实际应用三个方面来解释为什么电压kV中的“k”要小写。 一、历史背景. 电力输送技术的发展始于19世纪末20世纪初，当时人们开始使用高压输电线路来传 …

2024年10月1日 · A kilovolt (KV) is a unit of measurement for electric potential or voltage. It is defined as the potential difference between two points in an electric field that will cause a current of one ampere to flow through a resistance of one ohm. In other words, a kilovolt measures how much electricity can be pushed through a circuit.

2025年2月1日 · Symbol: kV or KV. 1999 October 21, Sally McGrane, “Getting Power to the People: The North American Electricity Grid”, in The New York Times ‎ [1] : Generators usually produce electricity at 7 kilovolts (a kilovolt is a thousand volts) to 25 kilovolts ; transformers at the generators step up the voltage, to 60 kilovolts to 500 kilovolts ...
