觸頭燒損 的英文怎麼說
中文拼音 [chùtóushāosǔn]
觸頭燒損
英文
contact burning-
3. the arc erosion of cuw80 / crcu integrated contact is primary forming the thicker shell and th shell flake off. 4
摘要（ 3 ） cuw8o主要是以產生較厚的以w為主的殼層，然後在電弧的反復作用下，殼層剝落，如此循環，導致觸頭的最終燒損。When there are rich cu defect in cuw / crcu integrated contact, the arc eroding loss of the contact is first from the spraying of cu, then the w skeleton flake off
（ 4 ）在觸頭存在富銅缺陷時，燒損首先產生的是噴濺，接下來是鎢骨架的大面積燒損。There are three modes for the invalidation of cuw / crcu integrated contact : splitting from the binding interface of cuw / crcu ; uneven distortion of contact finger and severe eroding loss
觸頭的動態失效主要有三種方式:在結合面處發生斷裂，嚴重燒損后無法接通，觸指變形。At present, the arc contacts in sfe switches is formed by the excellent property of electrical arc resistance of cu w alloy and the eminent conductivity together with high elasticity of crcu alloy, so - called cuw / crcu integrated contact
目前在sf _ 6斷路器中普遍使用的觸頭材料一般由耐電弧燒損的cuw部分和提供彈性和導電性的crcu部分組成，即cuw crcu整體觸頭。Switches play transmitting and cutting electrical current role during the working electrical net as a hinge, the important role will be brought into effect by the key part in switches - arc contact. if the contacts have invalidated and could not accomplished the important role during the working electrical net, switches would detonate, which result in the paralysis of whole net linked by the switches, the higher the transmitting voltage of net is, the bigger the affected area is, therefore, in order to decrease or avoid the arc eroding and invalidation during the net working, it is necessary to study the arc eroding and invalidation mechanism of contacts, sequentially make the whole net stable
可以說是電網中樞紐，而實施斷路器重要作用的核心部件就是弧觸頭，如果在動態使用中由於觸頭的失效而不能有效開斷的話，斷路器就會整機爆炸，後果就是它所連接的整個電網處于癱瘓狀態，電網的輸變電電壓越高，波及的面積越大，所以有必要對觸頭的動態燒損和失效進行詳盡的分析，減少或避免實際使用過程中的燒損和失效，從而穩定整個電網。2. the arc erosion of cuw70 / crcu integrated contact is first from the even volatilization of the surface cu, following by the formation of a w shell on the surface of w skeleton, then the shell flake off, after this, new arc erosion occur
（ 2 ） cuw70的燒損先是表層的cu均勻揮發，接著在骨架的表面形成一層以w為主的殼層，然後殼層剝落，裸露出來的繼續燒損，如此反復，導致了觸頭的燒損。The mechanism of arc eroding for cuw60 / crcu integrated contact is the volatilization of cu under the arc working, then the particles of w were worn off the matrix, this phenomena is n ' t formed continuous skeleton during the connecting and cutting. such - and - such repeating resulted in the arc erosion of the contact, until invalidation
（ 1 ） cuw60觸頭的燒損機理是以cu首先熔化噴濺，然後沒有形成連續骨架的w顆粒在關合的磨損中脫落，這是一個燒損周期，如此的循環導致觸頭的燒損，直至失效。分享友人
