Power distribution network feeder terminal for fault detection and positioning based on GPRS (General Packet Radio Service) communication

Abstract

The invention provides a power distribution network feeder terminal for fault detection and positioning based on GPRS communication, which comprises a fixing device, the upper end face of the fixing device is fixedly connected with a device main body, the upper end face of the device main body is rotatably connected with an electric turntable, and the upper end face of the electric turntable is rotatably connected with an electric rotating shaft. A solar panel is fixedly installed on the upper end face of the electric rotating shaft, a supporting device is fixedly connected to the lower end face of the fixing device, a driving motor is installed in the center of the interior of the supporting device, at least one set of external interfaces are embedded in the bottom of the supporting device, and a lead screw is rotationally connected to the upper end face of the driving motor. The FTU is intelligent terminal equipment installed on a power distribution room or a feeder, self-detection of the feeder terminal of the power distribution network is achieved, meanwhile, the later maintenance cost of the equipment is reduced, and the device is convenient to operate and high in adaptability.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a distribution network feeder terminal for fault detection and location based on GPRS communication. Background technique [0002] The feeder terminal (FTU for short) has the functions of remote control, telemetry, remote signaling, and fault detection, and communicates with the master station of distribution automation to provide the operation status of the distribution system and various parameters that are information required for monitoring and control, including switch status, electric energy Parameters, phase-to-phase faults, ground faults, and fault parameters, and execute commands issued by the power distribution master station, adjust and control the power distribution equipment, and realize functions such as fault location, fault isolation, and rapid restoration of power supply in non-faulty areas. FTU is an intelligent terminal device installed in the power distributi...

Problems solved by technology

[0005] However, the existing distribution network feeder terminals have the following problems in actual use: 1. The existing distribution network feeder terminals mostly use independent energy storage power supplies for power supply to avoid interference from line faults on the feeder terminals. The energy storage power supply often needs to be replaced after one or two years of use, which greatly increases the after-sales cost of the equipment. Second, the existing distribution network feeder terminal sampling sealing cover seals the internal circuit components of the device, but in maintenance It is difficult to disassemble and assemble during maintenance, which brings inconvenience to equipment maintenance or repair. 3. When the existing distribution network feeder terminal is in use, because the GPRS signal is easily interfered by other signals, the problem of communication interruption is more likely to occur, which makes the equipment fail. It is difficult for the remote end to find out in time, which will cause large-scale faults on the line
