Miniaturized intelligent online monitoring device and monitoring method for low-voltage distribution equipment

Abstract

The invention relates to the field of low-voltage distribution equipment, in particular to a miniaturized intelligent online monitoring device for low-voltage distribution equipment. The intelligent online monitoring device comprises a sensor unit, a processor unit, a wireless transmission unit, a power management unit and a storage unit, wherein the processor unit is connected with the sensor unit, the wireless transmission unit, the power management unit and the storage unit separately; and the processor unit is connected with the sensor unit, receives running state information and carries out storage, management and processing operation. The invention further relates to a monitoring method for the low-voltage distribution equipment. Compared with the prior art, the miniaturized intelligent online monitoring device has the beneficial effects that the information, such as temperature of incoming and outgoing lines, line current and voltage and smoke of the low-voltage distribution equipment is monitored online in real time through a wireless Internet of things and a novel sensing technology, and real-time computational analysis is carried out, so that fault early warning of a low-voltage distribution system is achieved and a fire accident is completely eradicated.

Description

technical field [0001] 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. Background technique [0002] 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;...
