Power distribution network fault positioning detector

Abstract

The invention relates to the technical field of power distribution network fault detection, and discloses a power distribution network fault positioning detector which comprises a supporting rod. The supporting rod is provided with a collection assembly used for positioning and detecting faults of the power distribution network, an installation device used for installing the collection assembly on the supporting rod, and a dismounting device used for dismounting the collection assembly from the supporting rod. Through cooperation of the fixing assembly, the clamping assembly, the transmission assembly and the collecting assembly, the collecting assembly can be rapidly and fixedly installed to the high position, needing to be installed, of the supporting rod, and through cooperation of the releasing assembly, the supporting assembly, the buffering assembly, the collecting assembly and other assemblies, the collecting assembly can be rapidly lowered down from the supporting rod; compared with the prior art, the device has the advantages of being convenient to install and operate, easy to maintain, free of climbing, capable of reducing the working intensity of electric workers and good in overall safety.

Description

technical field [0001] The invention relates to the technical field of distribution network fault detection, in particular to a distribution network fault location detector. 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 to various users step by step according to voltage. It is composed of overhead lines, cables, towers, distribution transformers, and isolating switches. , reactive power compensator and some auxiliary facilities, etc., which play an important role in distributing electric energy in the power network. At present, the voltage levels used in the power network mainly include 0.4kV, 6kV, 10kV, 35kV, 110kV, 220kV, 330kV, 500kV and 750kV , with the continuous development of social economy, social electricity consumption continues to increase, the scale of distribution network con...

AI Technical Summary

Problems solved by technology

[0003] Existing fault location detectors for distribution networks are mainly composed of acquisition units and collection units, where the acquisition unit is directly installed on the wire, and the collection unit is directly fixed on the high place on the utility pole through the cooperation of clamps and bolts. When in use, First, the acquisition unit collects the power data in the wire and transmits it to the collection unit through wireless transmission, and then the collection unit analyzes and processes the power data. When the power data fails, the collection unit will send the fault information and fault location to the distribution network. In the power grid line status monitoring system, the electric power repair personnel quickly arrive at the fault location and carry out emergency repairs to eliminate the fault of the distribution network. However, the collection unit is large in size and inconvenient to install. When the workers install the collection unit, First, you need to take the collection unit and climb to a high place on the utility pole with the help of a ladder, then hold the collection unit with one hand, and splice and install the clamps and bolts with the other hand. Carrying out maintenance work at a high place is difficult and prone to fall accidents, so it is urgent to design a simple-to-operate distribution network fault location detector
