为此其额动作电流只需躲开正常泄漏电流值即可(毫安级),所以能十分灵敏地切断接地故障,和防直接。而空气开关就是纯粹的过电流跳闸(安级)。空气开关分为:微型断路器和塑壳断路器两种,他们的基本功能有:1·过流、过载保护;2·短路保护。 (2)自动空气开关的额定电压≥线路额定电压。(3)自动空气开关的额定电流≥线路计算负载电流。(4)热脱扣器的整定电流=所控制负载的额定电流。(5)电磁脱扣器的瞬时脱扣整定电流≥负载电路正常工作时的峰值电流。

当小齿轮以3000rpm的转速,而扭矩为20kg-m时,传递至大齿轮的转速便降低了1/3,变成1000rpm;但是扭矩反而放大三倍,成为60kg-m。这就是发动机扭矩经由变速箱可降低转速并放大扭矩的基本原理。在汽车上,发动机输出至轮胎为止共经过两次扭矩的放大,次由变速箱的档位作用而产生,第二次则导因于终齿轮比(或称终传动比)。 电流互感器正常运行时,二次侧不准开路。电流互感器二次一旦开路,二次电流I2=0,一次电流I1仍为线路负荷电流,数值很大。从而引起铁芯饱和,磁通Φ剧增,将使铁芯过热,同时在二次线圈中产生几千伏甚至上万伏的高电压。

如上图所示,V1表示相电压,V2表示第二相电压,R1及R2分别表示正常安装到线路中的LED驱动器。当线路上零线(N)如图断开时,两个支路上的驱动器R1,R2相当于串联后接到380Vac电压上。因为输入内阻差异,当其中一个驱动器充电到启动时,内阻变小,电压可能大部分加到另外一个驱动器上,导致其过压损坏失效。 光电性能对于LED产品尤为重要,那么大家是否了解LED产品有哪些光电性能呢。下面我们一起来学习一下LED产品光电性能有哪些测试标准。1.电特性LED的电特性参数包括正向电流、正向电压、反向电流以及反向电压,该项测试一般是利用电压电流表进行测试,在恒流恒压源供电情况下。

从附件A:某电厂35kV线路BC相避雷器被击穿故障时的录波图也能看出BC两相的短路电流大小相等方向相反。2.2.2假定是发生了AC相间短路(便于分析忽略)计算负序电流:计算零序电流根据以上计算结果应该是负序II段动作跳闸,负序II段动拒动后再由其他保护动作跳闸。

图5图5,延时10秒以后,时间继电器KT动作,常闭触点断开,使KM3释放,KM3-2闭合,使器KM2吸合。KM3-1断开,使时间继电器KT线圈断电。这时,如图中主回路,KM1和KM2将电机接成三角形连接运行。完成了星三角转换。至于这个图有没有缺陷,和图1比较,有什么优缺点,欢迎有经验老评论里给出。 在中性点非直接接地的电力系统中,由于允许短时间单相接地运行,并且大多数情况下都装设有单相接地信 装置,所以广泛采用不完全星形接线方式。保护用电流互感器的三角形接线应用于Y/△接线的变压器差动保护。5.电流互感器运行中应注意的问题(1)电流互感器在运行中二次侧不得开路,一旦二次侧开路,,由于铁损过大,温过高而烧毁,或使副绕组电压升高而将绝缘击穿,发生高压触电的危险。
