查询词典 opening time

The mathematical models for overall breaking process of circuit breaker are developed, through which the driving mechanism and the arc chamber, the interruption performance and the opening velocity are closely connected, the breaking process under different interrupting conditions are simulated, then the arcing time difference is determined. The interrupting conditions include line charge current, breaker terminal fault current and short line fault current .

本文建立了一种把操动机构与灭弧室相联系、开断性能与运动特性相联系、一维和二维模型相结合的压气式SF6断路器开断性能的仿真方法，对不同开断条件下（包括线路充电电流开断、不同试验方式的端子短路开断、不同试验循环的近区故障）断路器的开断过程进行了分析，用仿真的方法确定了断路器在不同开断条件下能成功开断的燃弧时差，并给出了开断性能与运动特性之间的关系。

At this time, I found that the mantle cavity of its mouth in the shell formed an opening, through the information, I understand that the openings referred to as the "breathing hole", which is a gas and out of place.

This method is most special is the principle of simple and clear, setting out the process visible and tangible, it is applicable to a little bit knowledge of sheet l scene lofting geometry, which is a revolutionary approach, which not only greatly reduced the mapping workload, but also a great convenience in construction. Same time, it can also be a more traditional method (open show diagram drawing or galvanized sheet cut oil felt like, after re-opening in the pipe body gestures draw the cutting line method) is more accurate and pipe sections match exactly between the butt, thereby ensuring the steel fork tube and bend production quality.

该方法的最大特就点是原理简单明了，放样过程看得见摸得着，很适用于稍有一点几何常识的钣金工现场放样，这是一革命性的方法，它不仅大大地减少了制图工作量，而且也极大方便快捷了施工，同时它还可较传统方法（绘制开口展图后用油毛毡或镀锌板裁样再后在管身上比划绘出开口切割线的方法）来得准确无误与管段间对接严丝合缝，进而保证钢岔管和弯头的制作质量。

1 Opens uses this function to enter the memory root table of contents, in the root table of contents can list the system to lack the province folder, the establishment material clamps (when for the first time opening machine or user has not changed table of contents with the user document, root table of contents only has system to lack province folder).

使用该功能进入存储器根目录，根目录中会列出系统缺省文件夹、建立资料夹和用户文件（首次开机或用户未更改目录时，根目录只有系统缺省文件夹）。

An improvement on the die casting technology of aluminium hub includes drilling hole at the position of die, where the function of die is not affected, for preventing gas from coming into molten aluminium, mounting safety valve to the exhaust opening of die casting case for keeping proper pressure to save electricity and shorten die casting time, and increasing the water-flowing area of cooling disk or ring for higher cooling effect.

一在不影响模具本身功能部位钻孔增加排气通道，解决了压铸过程中产生的气体进入铝水问题。可使铝轮减少气孔。在压铸机箱体排气口部位，安装安全阀，能使压铸机箱体内保持适当的压力，工作时少进气、少排气，起到节电不堵浇口，缩短压铸时间，提高产量。冷却盘、冷却环改进后，增加了过水面积，提高了冷却效果。
