技术领域technical field
本发明涉及低压配电设备领域，具体涉及一种低压配电设备的微型化智能在线监控装置和监控方法。The invention relates to the field of low-voltage power distribution equipment, in particular to a miniaturized intelligent online monitoring device and a monitoring method for low-voltage power distribution equipment.
背景技术Background technique
随着城市低压配电设备直接面向用户，并且具有庞大的基数，已成为配电网的重要组成部分。在长期运行过程中，由于环境条件差，运行电流大，散热不好，设备的接头部位因绝缘老化或接触电阻过大等问题，容易出现过热现象，影响设备的使用寿命甚至导致火灾，从而造成大面积停电，直接影响整个台区的可靠运行，因此，供电公司会定期对低压配电设备的进出线表面温度进行测量；但是，据不完全统计，国内不少供电公司均出现过不同程度的低压配电柜和电表箱火灾事故，并造成巨大经济损失，甚至人员生命财产损失，因此有必要采取一种高效、便捷的措施对低压配电设备实现温度在线监测及火灾预警。As urban low-voltage power distribution equipment directly faces users and has a huge base, it has become an important part of the distribution network. During long-term operation, due to poor environmental conditions, large operating current, poor heat dissipation, and aging insulation or excessive contact resistance of the joints of the equipment, overheating is prone to occur, affecting the service life of the equipment and even causing fires, resulting in Large-scale power outages directly affect the reliable operation of the entire station area. Therefore, power supply companies will regularly measure the surface temperature of the incoming and outgoing lines of low-voltage power distribution equipment; however, according to incomplete statistics, many domestic power supply companies have experienced varying degrees of failure. Fire accidents in low-voltage power distribution cabinets and meter boxes have caused huge economic losses, and even loss of life and property. Therefore, it is necessary to take an efficient and convenient measure to realize online temperature monitoring and fire warning for low-voltage power distribution equipment.
然而，由于低压配电设备具有地域分布广和数量大等特点，其需要监测的节点多，若采用人工监测手段，效率低下，并且日常运维十分困难；以及，随着城市化进程的推进，及人民生活水平的提供，配用电设施的建设越来越多，维护量越来越大，人力配置难以覆盖。因此，本领域技术人员迫切需要一种智能运维系统，在降低人力需求的同时，保障用电系统的可靠运行。However, due to the wide geographical distribution and large number of low-voltage power distribution equipment, there are many nodes that need to be monitored. If manual monitoring is used, the efficiency is low, and daily operation and maintenance are very difficult; and, with the advancement of urbanization, As well as the provision of people's living standards, the construction of power distribution facilities is increasing, and the amount of maintenance is increasing, and it is difficult to cover manpower allocation. Therefore, those skilled in the art urgently need an intelligent operation and maintenance system, which can ensure the reliable operation of the power consumption system while reducing manpower requirements.
进一步地，低压配电系统网络拓扑结构复杂，由于历史原因或改扩建，大多数没有图纸记录，因而无法进行分区、分压、分线和分台区线损的自动统计线损计算。在配变负荷实时监测的基础上，负荷检测不全面，无法对配网规划提供决策。Furthermore, the network topology of the low-voltage power distribution system is complex. Due to historical reasons or reconstruction and expansion, most of them have no drawing records, so automatic statistical line loss calculations for line losses in partitions, voltage divisions, sub-lines, and sub-unit areas cannot be performed. On the basis of real-time monitoring of distribution transformer load, load detection is not comprehensive and cannot provide decision-making for distribution network planning.
目前，低压配电日常运维，只是采用示温蜡片或红外测温仪进行定期测温，两种方式均需要安排大量的人力来24小时巡检，且实际工作中因受到工作条件限制，运维人手不足，低压配电设备温度巡检工作被忽略，造成了不少事故和经济损失；而近年来出现的很多在线监测解决方案，无法很好的解决通信、工作电源以及施工便捷性的问题，难以批量应用推广。At present, the daily operation and maintenance of low-voltage power distribution only uses temperature-indicating wax sheets or infrared thermometers for regular temperature measurement. Insufficient manpower, the temperature inspection work of low-voltage power distribution equipment was ignored, resulting in many accidents and economic losses; and many online monitoring solutions that have emerged in recent years cannot solve the problems of communication, working power supply and construction convenience. , it is difficult to apply and promote in batches.
