arc light 1.弧光。2.弧光燈。

arc welding

The algorithm of image processing is the key . due to anomalous welding seam , the intensive arc light , random breaking of the bubble and gathering of the gas in the welding area , the seam images captured contain a lot of noise . in this case the noise must be removed and the welding seam is positioned accurately 本系統的圖像處理部分采用了ccd攝像頭和視頻捕獲卡,圖像處理的算法是最關鍵的部分,由于焊縫圖像并不是十分規則,而且在焊接時還會受到強烈弧光、飛濺和工件表面狀況的影響,因此在這種情況下,必須有效的排除干擾把焊縫的中心位置準確找出來。

Based on researching the function of every kind of eliminating arc loop , new concept was brought up in this paper , and the protective device for eliminating arc and overvoltage was researched and manufactured . when the arc light connecting the ground emerges , the chip synthesizing controller control the vacuum contacter which can be operated with dividing phase and make its fault phase earthed so that the arc light can be dissolved thoroughly 本文在研究各種消弧線圈的基礎上,提出全新的概念,研制出了消弧及過電壓保護裝置,該裝置在出現弧光接地時,通過單片機綜合控制器控制一組可以分相操作的真空接觸器,使故障相接地,達到徹底消除弧光的目的。

2 ignitor : - this is an electronic amplifier that receives electric current from the ballast and boosts voltage to ignite the arc light source in all environments . it initializes plasma discharge within the source by delivering a high - volt pulse to the electrodes 2 ignitor : -是一個從ballast接收電流并向所有環境中的arc light source釋放電壓的電子放大器,它通過向電極傳遞高脈沖來對等離子放電器進行初始化

It can be predicated that the study results are useful to the design of overvoltage protective device in electric power system and the development of canceling arc light earthed overvoltage device and small electric current chosen equipment 本文的研究結果對電力系統過電壓保護裝置的設計及消除弧光接地過電壓和小電流選線裝置的開發具有實際指導意義。

After switching on powerful arc lights , they saw great stalagmites - - some of them over forty feet high - - rising up like tree - trunks to meet the stalactites suspended from the roof 他們打開強力弧光燈,看見一株株巨大的石筍,有的高達40英尺,象樹干似的向上長著,與洞頂懸掛下來的鐘乳石相接。

Searching for a way to create an arc light for use on ac networks , tesla now found a new fundamental ideal on which to focus : high - frequency electrical phenomena 在特士拉想辦法讓電弧燈搭配ac電路使用時,發現了一個嶄新的基本想法并且專注其上,那便是高頻電流現象。

In the 1870s , many inventors were working on creating lighting devices , but until edison became involved , what existed was electric arc lighting 在1870年代,許多發明家都致力于制作照明設備,主要是設計發亮的電弧。

So once tesla had his arc lighting system running in rahway , his backers fired him and reorganized the firm 所以特士拉才剛在拉威市架設好他的電弧照明系統,他的資助者就將他解雇并重組公司。

The arc lights were sputtering overhead , and high up were the lighted windows of the tall office buildings 弧光燈在頭頂上方閃爍。更高處,寫字樓的窗子里透出光明。
