&nbsp; &nbsp; &nbsp; 目前国内外10kV以上的电缆主要采用带有金属护层的单芯电缆,因单芯电缆金属护层与芯线中交流电流产生的磁力线相铰链,使其两端出现较高的感应电压,故需采取合适的接地措施,使感应电压处在安全电压范围内(通常不超过50V,有安全措施时不超过100V)。当电缆护层绝缘发生损伤时,将使金属护套多点接地,从而产生护层循环电流,增加护套的损耗,影响电缆的载流能力,严重时甚至使电缆严重发热而烧毁。同时高压电缆线路金属层护套直接接地点的接地良好也十分重要,如果接地点由于各种原因不能有效接地,那么电缆金属护套的电位就会急剧升到几千伏甚至上万伏,很容易把电缆外护套击穿并在击穿点持续放电,造成电缆外护套温度升高甚至着火燃烧。</p> <p><strong>二、产品介绍</strong></p> <p>&nbsp; &nbsp; &nbsp; &nbsp; <strong>SN-HL1000型接地环流在线监测装置系统采用了环流法原理</strong>,即:单芯电缆金属护套在正常情况下(即一点接地),金属护套上环流极小,主要是容性电流,而一旦金属护套出现多点接地与大地形成回路后,环流显著增加,严重时可达主电流的90%以上。实时监测金属护套环流及其变化量,即可实现单芯电缆金属护套多点接地故障的在线监测,从而及时准确的发现接地故障,从根本上避免电缆事故的发生,保证电缆安全、可靠的运行。</p> <p>&nbsp; &nbsp; &nbsp; &nbsp; 高压电缆接地环流监测装置是由信号监测单元、数据通信单元、本地传感器单元组成,具备四路电流接入。有防电磁干扰和防水处理能力,采用工业级元器件,抗高温85℃,耐低温-20℃完成高压电缆接地环流检测,通过RS485通信模块将数据传送给本地监测屏柜。</p> <p style="text-align:center"><img alt="" src="/FileUpLoad/jsFile/638236565236261178_1.jpg" style="height:300px; width:200px" /></p> <p><strong>三、主要功能</strong></p> <p>&nbsp; &nbsp; &nbsp; &nbsp;1、用于护层环流缓变数值监测,反映护层接地良好程度、电缆老化程度、线芯负荷大小变化等情况;同时高压电缆线路正常运行情况下,当护层环流值产生突变减小或为零时,结合电调情况及电缆运行状态分析诊断模型,有效判断接地箱被盗或接地线被盗割。</p> <p>&nbsp; &nbsp; &nbsp; &nbsp;2、远程测量功能:系统将各监测单元安装于现场,在监控主机上可通过监测软件实时监测各测点信息。</p> <p>&nbsp; &nbsp; &nbsp; &nbsp;3、实时数据显示及查询功能:软件界面上可以显示多个测量通道的实时数据,并能查看相关历史数据等信息。</p> <p>&nbsp; &nbsp; &nbsp; &nbsp;4、良好的抗干扰功能:系统具有硬件和软件滤波,大幅度降低背景噪声影响。</p> <p>&nbsp; &nbsp; &nbsp; &nbsp;5、报警功能:系统具备实时报警功能及报警查询功能。</p> <p>&nbsp; &nbsp; &nbsp; &nbsp;6、平台对接功能:如有需要,系统具备与其他平台对接功能。</p> <p><strong>四、技术参数</strong></p> <p>&nbsp; &nbsp; &nbsp; &nbsp; 护层接地电流测量: 4路,0~300A(其他需定制)</p> <p>&nbsp;
