Portable remote monitoring system for monitoring temperature of live equipment in transformer substation

Abstract

The invention discloses a portable remote monitoring system for monitoring the temperature of live equipment in a transformer substation, and belongs to the power industry. The system comprises a video acquisition module, a control and data analysis module, a transmission module, a mobile phone APP and a cloud server; the control and data analysis module is used for setting an automatic patrol scheme executed by the video acquisition module, analyzing infrared thermal imaging images of electrified area devices acquired by the video acquisition module to discover an overheating device accordingto a relation of infrared thermal imaging images and temperature values, performing locking, reducing the distance from the video acquisition module to the overheating device, storing concrete information and records of the overheating device, and analyzing and recording the state of the video acquisition module itself at any time, and the information is displayed on the mobile phone APP and is stored in the cloud server. The system is convenient for management personnel to check on site through the mobile phone APP, can know the condition of operating devices in the electrified area of a transformer substation at any time and at any place, immediately knows and processes an overheating fault or an emergent fire point, and avoids greater economic loss.

Description

technical field [0001] The invention relates to the electric power industry, in particular to a portable remote monitoring system for temperature monitoring of electrified equipment in substations. Background technique [0002] Existing substation live area temperature monitoring systems generally have the following deficiencies: the existing technology is not intelligent enough, managers can only subjectively analyze and judge the operating temperature of substation live area equipment through a specific screen, and the monitoring system cannot make independent judgments Whether the equipment is overheated, which equipment is overheated, where is the specific space, and what is the reason for the overheating, which makes the conclusion of the fault judgment have subjective and human factors. And because there is dangerous high-voltage electricity in the electrified area of ​​the substation, the management personnel cannot enter the scene to observe and analyze the problem a...

[0002] Existing substation live area temperature monitoring systems generally have the following deficiencies: the existing technology is not intelligent enough, managers can only subjectively analyze and judge the operating temperature of substation live area equipment through a specific screen, and the monitoring system cannot make independent judgments Whether the equipment is overheated, which equipment is overheated, where is the specific space, and what is the reason for the overheating, which makes the fault judgment conclusion with subjective and human factors

And because there is dangerous high-voltage electricity in the electrified area of ​​the substation, the management personnel cannot enter the scene to observe and analyze the problem at the first time, so the golden time for troubleshooting is often missed; it is not accurate, and the existing technology can display the heat on a specific screen. Imaging map, but because the distance between each monitoring point and the camera is different, the monitoring effect is different. The effect of the long distance is relatively poor, and the effect of the short distance is relatively good, which leads to the farther the monitored temperature is, the more Inaccurate, this has little to do with the performance of the camera, it is related to the amount of infrared light entering the lens, so the temperature marked by the system is not necessarily the actual temperature of the equipment, sometimes the deviation is large, causing misjudgment by the management personnel; inconvenient: The existing technology must rely on fixed-position monitoring screens. Generally, the power supply bureau (or power bureau) that governs the substation is equipped with a monitoring center, and the monitoring screen of the system is configured in the monitoring center. The monitoring personnel obtain abnormal images and Alarm information, and then notify the management personnel of the substation. The management personnel may receive emails, or be notified by phone, or go to the monitoring center of the bureau to check the records. These cannot guarantee that the management personnel will obtain the most comprehensive, fastest and most intuitive information
