緩斷開關 的英文怎麼說
中文拼音 [huǎnduànkāiguān]
緩斷開關
英文
slow break switch-
The effect of overburden separation dynamic development under key stratum on grouting for bed separation space was analyzed, in order to deal with the problem that the current bed separation growing technology can not prevent the key stratum from breakage, put forward the isolated section - grouting technology for overburden bed separation space, integrated the virtue of growing for bed separation space and partial extraction, the bed separation grouting bodies, key stratum and isolated section pillars were made to constitute the load - carrying body all together, and to reach the purpose of reducing subsidence effectively, increase the coal seam extraction ratio, and accelerate the development of isolated section - growing technology for overburden bed separation space
摘要分析了關鍵層下離層動態發育對離層充填的影響，針對目前離層區充填工藝不能阻止覆巖關鍵層初次破斷的問題，提出了「覆巖離層分區隔離注漿充填」技術，它綜合離層充填與條帶開采技術的優點，通過離層區充填置換或減小分區隔離煤柱寬度，使「離層區充填體關鍵層分區隔離煤柱」形成共同承載體，從而達到有效減緩地面沉降的目的，提高了煤層采出率，促進了覆巖離層充填減沉技術的發展。At this time, slowly open the test ball valve completely, then a lot of water is discharged at the drainage outlet, close the test ball valve, the drainage device closes too, this shows that action of anti - pollution isolating valve is normal
此時緩慢將試驗球閥完全打開，這時排污口有大量水排出，關閉試驗球閥，排污器也隨之關閉，這說明防污隔斷閥動作正常。Legislation to conrol the municipal water pollution began as early as the late 1970s, yet the deteriorating quality of chinese municipal water environment hastens us to wonder why the expansion of cities keeps on pressing heavily upon it
我國關于城市水污染防治的立法早於70年代末便已開始，然而目前我國城市水環境所呈現的不斷惡化的態勢卻促使我們反思為什麼城市發展給水資源施加的壓力沒有得到任何緩解。Thirdly, the snubbers are designed to compress the switching voltage transient. when igbt is abruptly turned off, trapped energy in the circuit stray inductance is dissipated in igbt, causing a voltage overshoot and damaging igbt. this paper analyzes the principle of the snubber and discusses the impact of the parameters of the snubber on voltage overshoot
針對igbt工作過程中出現的電壓尖峰、電流尖峰和大的開關損耗問題，本文首先從理論上詳細分析了igbt逆變橋緩沖電路的工作原理，推導出緩沖電路各元件的參數計算公式，討論了緩沖電路各元件參數對關斷電壓波形的影響並進行了模擬分析。分享友人
