对VS1(VD4)真空断路器特性试验问题的分析--论文.doc

several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measuremen器可以通过测量分、合闸时间来反映分、合闸速度是否合格，并称“只要测得的分、合闸时间在合格范围内，就可以认为分、合闸速度不会有问题 ”我认为这种观念是十分错误的，在这种错误观念误导下，再加上VS1—12和VD4断路器确实也很难测量可动触头速度，因此目前使用部门基本上
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured

在现场不测量其速度，甚至也有些开关厂对生产的VS1—12断路器也不测量速度。如2007年9月在中置柜检修比武中，由于现场提供的VS1—12断路器条件限制而未能进行速度测量，为此引起了系统内有关方面的重视，要求尽快设法解决这个问题。
2、分合闸时间与分合闸速度的差异
断路器的分、合闸时间不能
