以变压器接线方式Y/△11为例,讲解星转角(Y△)问题:1.1为了便于理解本文假设:变压器高低压侧额定电流均为1A;变压器平衡系数为1;从相量图我们可以看到两侧电流之间会出现30的相位差,那怎么干掉这30°的相位差呢?当然是要通过保护装置的软件算法对相位进行校正。微机型保护装置有2种相位校正方式:三角形侧向星形侧校正(△Y)和星形侧向三角形侧校正(Y△)。版权所有。我国广泛采用的是星形侧向三角形侧校正(Y△)方式,所以本文也只讲解星形侧向三角形侧校正(Y△)这种方式。
用于传输和分配电能的电缆。常用于城市地下电网、发电站的引出线路、工矿企业的内部供电及过江、过海的水下输电线。在电力线路中,电缆所占的比重正逐渐增加。电力电缆是在电力系统的主于线路中用以传输和分配大功率电能的电缆产品,其中包括1-500KV以及以上各种电压等级,各种绝缘的电力电缆。

变频器接线要求1)变频器和电机的距离应该尽量的短。这样减小了电缆的对地电容,减少干扰的发射源。2)电机电缆应独立于其它电缆走线,其小距离为500mm。同时应避免电机电缆与其它电缆长距离平行走线,这样才能减少变频器输出电压快速变化而产生的电磁干扰。如果控制电缆和电源电缆交叉,应尽可能使它们按90度角交叉。与变频器有关的模拟量信号线与主回路线分开走线,即使在控制柜中也要如此。3)模拟量控制线选用屏蔽线,屏蔽一端接变频器控制电路的公共端(COM),不要接变频器地端或大地,另一端悬空;动力电缆选用屏蔽或者从变频器到电机全部用穿线管屏蔽,或遵从变频器的用户手册。
在缆芯中和屏蔽层的内外表面用石油膏填充或浇注处理,以防止煤矿中水分侵入。在煤矿常见的32~C一62~C的环境条件下。用于平巷、斜巷及机电硐室做通信线以及用于平巷,竖井或斜井作主信号传输。矿用通信电缆结构介绍:1、导线:退火裸铜线,铜线直径为0.30,0.42,0.52,0.60,0.70,0.80,0.90(mm)。

1952年,瑞典在北部发电厂敷设了380千伏超高压电缆,实现了超高压电缆的应用。到80年代已制成1100千伏、1200千伏的特高压电力电缆。我厂引进先进设备,先进技术。电力电缆的基本结构由线芯(导体)、绝缘层、屏蔽层和保护层四部分组成。
dingradiusofmulticore-cableshouldnotlessthan15timesofthecablediame。电缆的交流额定电压500V以下,电缆线芯的长期工作温度应不超过70℃。
ˎ̥RVV电缆全称铜芯聚氯乙烯绝缘聚氯乙烯护套软电缆,又称轻型聚氯乙烯绝缘聚,俗称软护套线,是护套线的一种。RVV电线电缆就是两条或两条以上的RV线外加一层护套。RVV电缆是弱电系统常用的线缆,其芯线根数不定,两根或以上,外面有PVC护套,芯线之间的排列没有特别要求。
