Inspection system based on mobile inspection apparatus of transformer station and inspection method thereof

Abstract

The invention discloses an inspection system based on a mobile inspection apparatus of a transformer station and an inspection method thereof. The inspection system comprises a monitoring center; and the monitoring center is connected with at least one station-level mobile inspection apparatus intelligent inspection system of a transformer station through a network. And all station-level mobile inspection apparatus intelligent inspection systems include at least one base station. Meanwhile, an environmental information collection subsystem and fixed point auxiliary monitoring subsystems that are installed at places needing monitoring equipment in the transformer station are arranged in the transformer station. A detection unit comprises an infrared detection unit and an ultraviolet detection unit; and the ultraviolet detection unit is composed of an ultraviolet video server and an ultraviolet detection apparatus. According to the invention, an inspection path is optimized; the safety protection is good; and the intelligent degree is high; moreover, the inspection system has advantages of whole time fault detection and seamless video monitoring; and a novel technical detection means and omnibearing safety guarantee are provided for an intelligent transformer station.

Description

technical field [0001] The invention relates to the technical field of power system substation operation and maintenance, in particular to an inspection system based on a mobile inspection device for a substation and an inspection method thereof. Background technique [0002] For a long time, substation inspection work has been carried out manually. The traditional manual inspection method not only has shortcomings such as high labor intensity, low work efficiency, scattered detection quality, and single means, but also cannot be manually detected afterwards. The data is accurately and timely transmitted to the management information system for use in work. [0003] With the promotion of unattended substations, the inspection workload of substations is increasing, and the inspection rate and timeliness cannot be guaranteed. Especially after special geographical conditions such as plateaus and Gobi or extreme weather such as strong winds, fog, ice and snow, hail, thunderstor...

AI Technical Summary

Problems solved by technology

When inspecting specific equipment, the mobile inspection device does not optimize the path, and some unnecessary paths need to be taken, which not only wastes battery energy, but also prolongs the detection time of the mobile inspection device, and the detection efficiency is not high

[0007] 2. The pattern recognition function of the mentioned mobile inspection device is weak

The status of the current high-voltage circuit breaker equipment in substations mostly depends on manual inspection or online monitoring. Manual inspection is labor-intensive and low in work efficiency; inspection / verification is not in place, and the docking period with the existing management information system is long; the mentioned mobile The online monitoring of the inspection device has fewer sampling signals and insufficient data; there is no record of the movement process; the analysis accuracy is not high, and the diagnostic conclusion is not convincing, etc.

[0008] 3. The mentioned mobile inspection device lacks a safety protection system

During the commissioning and normal inspection process of the mobile inspection device, especially when it is operated by wireless technology, due to the lack of effective protection means, when the mobile inspection device encounters an unexpected situation, the shell collides with the equipment and is damaged.

[0009] 4. The mobile inspection device mentioned cannot detect the early failure of the equipment in advance

Infrared detection is easily affected by infrared radiation in the environment, especially solar radiation, so infrared detection generally cannot be carried out during the day, which causes some equipment failures to be detected and discovered in time; infrared detection usually detects late-stage failures of equipment, and cannot detect early-stage early warning

[0010] 5. The mentioned mobile inspection device cannot be effectively combined with the traditional video surveillance system

There is still a large monitoring blind spot, and it is difficult to truly meet the requirements of video inspection and all-round coverage

[0011] 6. The mobile inspection device mentioned cannot cooperate with the sequence control system

The existing inspection system based on the substation mobile inspection device cannot realize the automatic identification of the equipment status after the switching operation, cannot interact with the substation sequence control platform, and cannot realize the sequence control process of the switching operation
