The invention relates to the technical field of power distribution network maintaining, in particular to an early warning method and system for a power distribution network. The early warning system for the power distribution network comprises multiple power measurement devices, a camera device, a voice collector, a communication device, a display device, a storage device and a microprocessor, andis characterized in that the power measurement devices are installed at the input ends and the output ends of all sets of power distribution equipment in the power distribution network, and comprisepower detecting units and power value display units, and identifications (IDs) are distributed to the power measurement devices respectively; the voice collector collects work noise of power protection equipment, and the camera device and the voice collector are connected with the microprocessor through the communication device. The early warning method and system have the advantages that by monitoring the power of the input ends and the output ends of the equipment in the power distribution network and the work noise, early warning is conducted on a failure of the power distribution network in time, failure disposition and maintaining arrangement are guided, the efficiency of failure disposition is improved, and the operating stability of the power distribution network is improved.
Description
technical field [0001] The invention relates to the technical field of distribution network maintenance, and in particular to a method and system for fault warning of power protection equipment. Background technique [0002] The distribution network refers to the power network that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution facilities or distributes it to various users step by step according to voltage. It is composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators and some ancillary facilities. It plays an important role in distributing electric energy in the power grid. The power consumption of important users is the focus of power supply enterprises. Although there are not many important users, they occupy an important position in the local society, politics, and economy. Interruption of power supply may cause greater p...
