An anti-strong magnetic all-weather dry-type reactor online monitoring device and method

Abstract

The invention discloses an on-line monitoring device and method for a dry-type reactor against strong magnetism and all-weather, comprising a thermal imager, a collection unit, a communication unit and a shell made of magnetic conductive material. Layer structure, one end of the opening is installed with a germanium glass window for infrared rays to pass through, and one end of the opening is installed with a rear baffle of the shell for sealing it. and the rainproof edge of the shell, the shell is installed on the ground pre-embedded base through a bracket, and the shell is provided with a thermal imager, a collection unit, and a communication unit; the middle of the bracket 5 is installed with a thermal imager and a collection unit. , The communication unit provides power storage battery. The monitoring device prevents the interference of the strong magnetism generated by the dry reactor to the monitoring device. By analyzing the thermal imaging spectrum of the dry reactor, it realizes all-weather online monitoring of the dry reactor, which can effectively avoid the occurrence of dry reactor accidents and ensure the safe and reliable operation of the substation. .

Description

technical field [0001] The invention belongs to the technical field of monitoring equipment for dry reactors, and relates to an anti-strong magnetic all-weather online monitoring device and method for monitoring the health status of dry reactors by using thermal imaging maps. Background technique [0002] So far, many substations and converter stations have experienced dry reactors (dry-type air-core reactors or dry-type half-core reactors or dry-type iron-core reactors, referred to as dry reactors) serious burnout accidents, including ultra-high voltage, UHV substations and UHV converter stations, these accidents have seriously affected the safe operation of substations and caused huge losses. [0003] The reason for dry reactor burning is: dry reactor generally adopts cylindrical winding method, each dry reactor coil is composed of multiple packages, the turn insulation between wires is very thin, burrs, metal debris or other Foreign objects can easily pierce the turn ins...

AI Technical Summary

Problems solved by technology

[0018] (1) The intensity of the leakage magnetic field near the dry resistance is very high, far exceeding the magnetic induction intensity allowed for the normal operation of the thermal imager and other electronic components and electronic equipment in the device. The weak current equipment will be interfered by the strong magnetic field and even damaged

[0019] (2) The dry resistance on-line monitoring device must be continuously operated outdoors for 24 hours. Bad weather conditions will make the device unable to operate continuously and normally - electronic components and batteries will fail if the temperature is too high or too low, rain, snow, Ice, dust, and strong wind will affect the monitoring effect
