Description

一种干式变压器智能管理系统 技术领域
本发明涉及电力设备控制技术领域，特别涉及一种干式变压器智能管理系统。
背景技术
智能变压器是智能电网的核心设备，正是由于智能变压器技术的不断完善才能够推进我国智能电网的建设。智能电网发展方向是“一次”与“二次”系统的融合，其追求的功能目标是智能化、自适应，追求的经济目标是综合建设成本最低，运行维护费用最低。随着国网泛在物联网的推进和人工智能的发展，智能变压器将成为未来的研究方向之一，市场需求日益增长。
现有技术方案中，在变压器壳体内部的变压器本体、三相电流互感器、铁心接地电流互感器、中性点电流互感器、温湿度传感器、处理器、局部放电超高频探头，这些传感器采集的数据经过处理器，可实时监控变压器的运行状况。现有技术方案只是简单的监测分析电压、电流、温度数据，同时缺少节点测温、无线通讯、能效分析、变压器寿命评估、APP应用、后台运维监视系统等。
同时，变压器还存在如下问题：一是干式变压器在供电系统中属于监控盲区，变压器的运行状态如电流电压、功率、绕组温度等信号无法上送后台监控，用户无法掌握变压器的运行状态，导致变压器运行异常时不能及时断电检修，在长期运行中出现设备损坏或事故扩大；二是由于变压器运行环境复杂，传统的温控器仅能控制风机的启停，高温预警，无法对变压器的运行状态进行统计分析，不能有效预测变压器的使用寿命；三是干式变压器多安装在工厂、楼宇或地下室等空间有限场所，大多没有运维人 员，设备一旦出现故障，运维人员往往无法及时获取故障信息，在事故发生或扩大化后才能从上级保护设备发现故障现象，这种粗放式管理无法满足当前用电负荷对供电高可靠性的要求；四是变压器所带负载多样，运行中会出现三相不平衡现象，由于没有变压器运行数据，无法计算变压器能量损耗等经济数据，客户无法以经济运行方式实时调整变压器负载率，以最有方式运行。
