产品介绍
产品简述
低压综合配电成套装置(以下简称配电箱),集电能分配,低压无功自动补偿,电能计量,配变参数自动记录为一体;对低压负荷进行不间断的监测和记录,根据无
功电流的大小,实现三相或分相全量程自动跟踪补偿无功功率,适用于户外正常使用条件下,额定绝缘电压550V,额定工作电压交流400V,额定电流至125A,频率50Hz,50KVA-630KVA的配电变压器,变压器中性点直接接地,适用于城市和农村电网。
箱体采用低压综合配电箱的型式(JP),原则上采用卧式,安装在配电变压器下方,对地距离不小于1.5m或安装在变压器下方的地面上。材料可选用不锈钢板,经高精度剪板机下料、折弯、冲压、焊接、抛光而成;也可选用2mm的优质冷轧钢板焊接而成。箱体正面、背面均装有开启门、外型有类似房屋带有檐口的顶盖,使雨水不能停留。箱顶左右两侧有通风窗,窗内装有丝网,即能散热又能防止小动物进入箱体,防护等级达到IP33以上。
箱内设有检修照明灯,门打开后,检修灯即亮。为有效防止行人随意损坏,箱体不设观察窗。配电箱分前后两部分,共四个工作室;前部分设计两个工作室,左边是进线计量室,右边是出线断路器室;后部分设计两个工作室,左边是出线断路器或无功补偿室,右边是无功补偿室,前后两部分中间用隔板隔开,形成四个独立的工作室,由于四个部分是独立的,故可以防止故障由一部分扩展到另一部分。进线从侧面进线。箱内电气元件安装合理、牢固、安装维修方便。
无功补偿部分的主要技术参数同DJ型配电监测无功补偿成套装置,出线、计量可根据用户所提供的方案设计及生产。该产品通过国家电力公司、电力工业无功补偿成套质量检验测试中心性能测试,各项技术指标符合国家标准GB7251.1-2005/ IEC60439-1:1999。
可根据用户所提供的方案图生产所需的外型尺寸。
