Abstract

The invention relates to an online monitoring system for the working condition of power distribution equipment. An online monitoring and early warning system for the working conditions of power distribution equipment. For a power supply station and its substations, the power supply station is equipped with an early warning computer, and a wireless network communication base station is established. Each distribution transformer is equipped with a power distribution equipment detection and early warning system. terminal, the power distribution equipment detection and early warning terminal is equipped with a wireless transmission and reception communication module, and the power distribution equipment detection and early warning terminal is wirelessly connected to the wireless network communication base station through the wireless transmission and reception communication module; the early warning computer of the power supply station is connected through a The receiver with the two-way communication module is connected to the wireless network communication base station; the on-line monitoring and early warning system for the working condition of the power distribution equipment is formed by the early warning computer of the power supply station, the detection early warning terminal of the power distribution equipment and the wireless network communication base station. The implementation of the invention helps to provide a highly reliable and high-quality power consumption environment for the end users of the power distribution system.

Description

technical field [0001] The invention relates to an online monitoring system for power distribution lines and equipment, in particular to an online monitoring and early warning system for working conditions of power distribution equipment. Background technique [0002] The power distribution system belongs to the end of the power supply and consumption. In the traditional operation management process, the lack of scientific operation management often leads to frequent accidents in power consumption, such as: high-voltage insurance drops or fuse blown and low-voltage fuse blown The lack of phase operation caused by the three-phase power equipment and household appliances will burn out; the unbalanced three-phase current will increase the current of the neutral line loop, increase the loss of the low-voltage line, and even burn the zero line, resulting in abnormal overvoltage burnout Household appliances; the overload operation of distribution transformers and the influence of ...
