Transformer integrated temperature monitoring device for infrared image recognition

Abstract

The invention discloses a transformer integrated temperature monitoring device for infrared image recognition, and relates to the technical field of comprehensive monitoring for grid power transformers. The transformer integrated temperature monitoring device is characterized in that an embedded system control core unit is connected with a touch screen; and an image acquisition module is connected with the embedded system control core unit. The control core unit of the transformer integrated temperature monitoring device acquires an infrared image of a setting range of a transformer top view region from the image acquisition module, retrieves the image according to a set infrared temperature threshold and a pixel change threshold and transmits the image to a cloud platform through the core control unit and an embedded GPRS / DTU module when exceeding the thresholds. A micro-service function of the cloud platform is for image pattern recognition. If the temperature exceeds the threshold, threshold-exceeding equipment and the fault type are recognized, early-earning information and handling suggestions are transmitted to the operation and maintenance personnel; and if the personnel get close to the transformer, a camera collects a visible light image and uploads the image to the cloud platform for behavioral identification, LED lamplight warning and voice warning are performed if there is a dangerous behavior, and warning information is sent to the operation and maintenance personnel at the same time.

Description

Technical field: [0001] The invention relates to a transformer comprehensive temperature monitoring device for infrared image recognition, which belongs to the technical field of power transformer comprehensive monitoring. Background technique: [0002] The safe and reliable operation of power transformers is the fundamental guarantee for the normal operation of power systems. During production and operation, distribution transformer damage and faults occasionally occur, which not only cause the loss of power assets and power loss caused by power outages, but also affect the high-quality service of power supply and cause customer complaints. [0003] Operational data show that distribution transformers are overloaded and the temperature of the iron core rises, which causes premature aging of the transformer coil insulation and causes electrical breakdown, accounting for 35% of transformer damage accidents; the oxidation and heat damage of wiring pile heads on both high and l...

Problems solved by technology

[0004] At present, the daily operation and maintenance inspection of power system transformers still relies on manpower, which cannot avoid the occurrence of faults

Reflected as: 1. The inspection interval is long, with an interval of 24 hours or more; 2. There are many inspection items, including transformer shell temperature, oil temperature, wiring pile head temperature, etc. The effect is affected by the inspector's work experience, observation ability, and sense of responsibility. influences;

[0005] In addition, the 10kV power transformers of power supply companies and special customers are often stolen by criminals, and occasional electric shock casualties occur during the theft
