Pagsukat ng fiber optic sensor ng temperatura ng gate ng kutsilyo

Why does the knife switch need temperature measurement

With the increasing demand for power reliability, a certain component in a substation heats up severely and loses its original function, which means it will cause major power outages to users or major equipment damage accidents to the substation. The knife switch components of the substation, due to their rotatability and frequent operation, have always been the most vulnerable components to overheating and damage in the substation. In the safe operation system of power equipment, temperature is an important parameter to verify the normal operation of primary equipment. The connection parts of power equipment, due to changes in climate, equipment foundation, teknolohiya sa pagproseso, environmental pollution, severe overload operation, contact oxidation, and other reasons, cause loose crimping, insufficient pressure, changes in contact parts, and ultimately increase contact resistance. When current passes through, the temperature rises, causing equipment aging, insulation decline, at sa malalang kaso, triggering arc short circuits, burning out equipment, expanding the scope of equipment damage, reducing equipment service life, and even easily causing a fire and explosion of the equipment, especially the dynamic and static contact parts of the movable knife switch, which have a high failure rate, all of which constantly threaten the safe operation of power equipment.

What are the temperature measurement methods for the knife switch

The traditional inspection method uses manual operation or automatic program control of unmanned aerial vehicles with dual light cameras (visible light camera at thermal infrared camera) para sa inspeksyon. Pagkatapos, Ang mga visible light na larawan at infrared na larawan ay ini-export mula sa mga unmanned aerial na sasakyan. Pagkatapos, sa pamamagitan ng paghahambing ng nakikitang liwanag na mga larawan, ang kagamitan sa switch ng kutsilyo at mga contact point sa mga infrared na larawan ay matatagpuan at minarkahan. Sa wakas, binabasa ang mga may markang infrared na larawan gamit ang software sa pagsukat ng temperatura upang ipakita ang temperatura ng mga contact point ng switch ng kutsilyo. Gayunpaman, dahil sa katotohanan na mayroong hindi bababa sa dose-dosenang mga infrared na larawan na kinunan sa isang solong inspeksyon, at ang bawat larawan ay naglalaman ng higit sa 20 mga aparatong switch ng kutsilyo, Ang manu-manong pagmamarka ng mga contact point ng switch ng kutsilyo sa mga infrared na larawan ay napakahirap at nakakaubos ng oras. At saka, mahirap na direktang mahanap ang kagamitan sa switch ng kutsilyo mula sa mga infrared na larawan, and it is often necessary to compare visible light photos taken at the same time to determine the position of the knife switch in infrared photos. Manual marking may result in missed or incorrect labeling. Kasabay nito, the inspection frequency of substations (at least once a day) is high, and the manual marking work is very time-consuming. There is an urgent need for a more efficient method to replace it.
The traditional temperature measurement methods for substation knife switches include infrared thermal imaging temperature measurement, point infrared temperature measurement, at wireless na pagsukat ng temperatura. The above temperature measurement methods either have low real-time performance, mataas na gastos, or are prone to damage and cannot automatically adjust the temperature. They cannot automatically cut open or close when the temperature of the knife switch suddenly rises.

Knife switch fiber optic temperature measurement device

Ang fluorescence fiber optic na sistema ng pagsukat ng temperatura is a device that controls the high-speed electric telescopic rod to work quickly and cut off when the temperature of the knife switch arm exceeds a certain set value, avoiding damage to electrical equipment caused by high temperature of the knife switch. Higit na mahalaga, due to the large temperature difference between the two sides of the temperature difference generator on the knife switch, the power generation is large, and the fan simultaneously cools down on one side of the temperature difference generator. The temperature difference generator absorbs a large amount of heat. Kapag bumaba ang temperatura ng braso ng switch ng kutsilyo sa ibaba ng itinakdang temperatura, kinokontrol ng controller ang high-speed electric telescopic rod para mabilis na isara ang knife switch arm, pagkamit ng matalino at awtomatikong kontrol ng switch ng kutsilyo, pagtitipid ng lakas-tao at materyal na yaman, at pagbabawas ng mga pagkalugi sa ekonomiya; Direktang ipakita ang signal ng temperatura at himukin ang lokal na aparato ng alarma upang magpadala ng impormasyon, pagbibigay ng isang remote alarm output interface para sa koneksyon sa iba pang mga sistema ng impormasyon. Ipadala ang alarma at impormasyon ng data sa malayo sa monitoring center para sa real-time na pagsubaybay sa katayuan ng switch ng unmanned substation, napapanahong pagkukumpuni, at maiwasan ang pagkalugi sa ekonomiya.
