正序 负序 零序? 发电机 正常运行时发出的是三相对称的正序电流。发电机转子的旋转方向和旋转速度与三相正序对称电流所形成的正向旋转磁场的转向和转速一致。当电力系统发生三相不对称短路或负荷三相不对称时,在发电机定子绕组中就流过负序电流,该负序电流在发电机气隙中产生反向(与正序电流产生的正向旋转磁场方向相反)旋转磁场,它相对于转子来说为2倍的同步转速,因此在转子中就会感应出电流,该电流在转子端部附近沿周界方向形成闭合回路,给发电机造成灾难性破坏,即通常所说的“负序电流烧机”,这是负序电流对发电机的危害。 零序电流是把不对称分量分解成对称分量的零序分量,三相电流相量和不为零时产生的 查看更多 2个回答 . 1人已关注

浙江金华市区发生8吨强酸泄漏事故 低空被染红? 浙江金华市区发生8吨强酸泄漏事故 低空被染红 现场图片 现场图片 新华网杭州9月17日电 (记者岳德亮、王小川)17日下午,浙江金华市区秋滨街道熟溪路866号一废弃厂区内发生废酸泄漏事件,泄漏的强酸估计约8吨。 据当地消防部门一位负责人介绍,最先报警的是与该废弃厂区一路之隔的金棉纺织有限公司员工。负责消防工作的曹师傅说,17日15时左右,公司食堂一名厨师途经熟溪路,发现道路两侧的窨井内在冒烟,闻了后眼睛发酸、嗓子发干,遂报告给公司门卫。门卫向上汇报,他闻讯后立即打了119报警。 金华当地媒体的记者张黎明表示,他在赶到事发现场附近时就发现,两侧窨井内喷涌出铁锈红的浓烟,远处的低空已经被染黄。抵达事发地时,发现低空甚至被染红。民警和消防员立即在各个路口设置警戒带,阻止路人靠近。下风口的“大明铝业”等公司干脆给员工放假。 事发现场,一名满头大汗的紫衣男子自称是废弃厂区的业主,姓金。他说,该厂区原先是江南化工厂,4年前化肥厂搬迁至兰溪,这里就剩下几只槽罐,里面装有生产原料之一的废酸。槽罐露天堆放,日晒雨淋加上酸性腐蚀,曾发生过泄漏。“这次发生泄漏的槽罐,直径约4米,实际装有10吨左右废酸。废酸的主要成分有 硫酸 、 硝酸 和 盐酸 ,浓度有70%。” 经过消防、环保等部门两个多小时的抢险,该泄漏事故被控制。17日晚,金华市相关部门对该金姓业主进行传唤,作进一步调查。 查看更多 6个回答 . 1人已关注
