double reverse
解釋
雙反向傳球戰術-
This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time
該鉆機採用曲柄連桿、游梁式沖擊機構，使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主，遇到特殊情況，用連桿沖擊不能鉆進時，可轉為卷揚沖擊，沖程可調，因連桿沖擊機構連續工作，所以實現了自動沖擊鉆進，可提高鉆進效率，減輕勞動強度;採用泵吸反循環的方式排渣，既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難，又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構，既保證了鉆具處于平衡狀態，又大大簡化了該機構設計，降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立，減少了輔助作業時間。 -

This can fully consider the effect of the structure of transmission line and the selection of lighting parameter etc. by calculating and analyzing various of factor that affect the lightning tripping probability of 500kv double circuit transmission line, we can draw the conclusions : the result by intersecting method is more accord with the practicality circumstance than by existing standard methods, using unbalance high insulation and reverse sequence of wire can reduce the contemporary outage rate of double circuit line, reducing the footing resistance is one of the most efficiency method to reduce the back stroking rate of double circuit transmission line, the double back stroking rate and the single back stroking rate will fall by three ground wire, when the footing resistance is 10 ohm, the back stroking rate by three ground wire is 83 percent of by two ground wire
在分析輸電線路繞擊耐雷性能時，對線路的雷電屏蔽問題進行了分析，提出對擊距法進行改進，充分考慮了風速的影響因素，編寫了具有工程實用價值的計算線路繞擊耐雷水平的程序，此方法可以充分考慮線路結構和雷電參數等對繞擊率的影響。通過對影響500kv同桿雙回線路雷擊跳閘率的各種因素進行了計算和分析，得到以下結論：採用相交法的計算結果比定義法更符合實際運行情況。採用不平衡高絕緣方式和導線逆相序排列可以大大降低雙回同時跳閘率。 -
