我國帶電作業的發展簡史（1953~2009）

Brief history of the development of live working in China (1953-2009)

我國的帶電作業技術起步於20世紀50年代，當時正處於國民經濟恢復和發展的初期。由於發電量迅速增長，電力設備明顯不足，大工業用戶對連續供電的需求日益嚴格，常規的停電檢修因而收到限制。當時，我國大的鋼鐵基地鞍山，扁電纜YCB3*11+2*9卷筒扁電纜停電尤為困難。為了解決線路要檢修而用戶又不能停電的矛盾，當時稱之為“不停電檢修技術”開始得到發展與應用。

China's live working technology started in the 1950s, when it was in the early stage of national economic recovery and development. Due to the rapid growth of power generation and the obvious shortage of power equipment, the demand of large industrial users for continuous power supply is increasingly strict, so the routine outage maintenance is limited. At that time, Anshan, China's largest steel base, was particularly difficult to cut off power. In order to solve the contradiction that the line needs to be overhauled and the user can't cut off the power, the so-called "on line maintenance technology" began to be developed and applied.

1953年，鞍山電業局的工人開始研究帶電清掃、更換和拆裝配電設備及引線的簡單工具。

In 1953, workers in Anshan Electric Power Bureau began to study simple tools for cleaning, replacing and disassembling power distribution equipment and leads with electricity.

1954年，採用類似樺木的木棒來制作的工具完成了3.3KV配電線路不停電更換橫擔、木桿和瓷瓶的作業。盡管工具顯得十分笨重粗糙，但卻成功地進行了3.3KV配電線路的“地電位”帶電作業，也是第一次實現帶電作業。

In 1954, a birch like tool was used to replace crossarms, wooden poles and porcelain bottles for 3.3kV distribution lines without power failure. Although the tools are very bulky and rough, the "ground potential" live working of 3.3kV distribution line ha
