Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0041] Such as figure 1 A hybrid power supply device for grid wireless sensor network nodes is shown, including a battery, a CT energy harvesting device and a switching circuit; the output end of the battery is connected to the input end of the switching circuit, and the output end of the CT energy harvesting device is respectively connected to the input end of the switching circuit and the sensor node, the output end of the switching circuit is connected to the sensor node.

[0042] The CT energy harvesting device is the main power supply, and the battery is the backup power supply. When the line is working normally, the CT energy harvesting device supplies power to the node; when the line is faulty or no-load, the battery provides energy to the node. Due to the monitoring of nodes, the time of li...

Abstract

The invention discloses a hybrid power supply device oriented to a power grid wireless sensor network node. The hybrid power supply device comprises a storage battery, a CT energy taking device and a switching circuit; the output end of the storage battery is connected with the input end of the switching circuit, the output end of the CT energy taking device is connected with the input end of the switching circuit and the sensor node, and the output end of the switching circuit is connected with the sensor node. When the circuit works normally, the CT energy taking device supplies power to the node; when the circuit has a fault or has no load, the storage battery supplies energy to the node. As the node is monitored, fault time of the circuit will be short, power supply time of the storage battery is relatively short, consumption is low, the storage battery is not replaced for a long time, and therefore the requirement for energy consumption of the node can be completely met by adopting combination of the two power supply modes.

Description

[0001] technical field [0002] The invention relates to a power supply device for grid parameter detection sensor nodes, in particular to a hybrid power supply device for grid wireless sensor network nodes. [0003] Background technique [0004] In order to improve energy utilization efficiency, reduce the delay of manual line inspection, and improve the reliability of power supply, power grid companies currently need various types of sensors to monitor the electrical parameters and meteorological parameters of the power grid in real time. However, sensor nodes are usually powered by batteries, and the capacity of batteries is limited. When the power is used up, the nodes will lose their function, which will affect the operation of the entire monitoring system. [0005] The amount of data to be monitored for distribution network fault monitoring is very large, there are many nodes, and the nodes are distributed in a wide area and the environment of the deployment area is c...
