The best manufacturer of fiber optic sensors for measuring the temperature of bus ducts-INNO

Met de ontwikkeling van wetenschap en technologie en de markteconomie, intelligente besturing wordt steeds populairder. De vereisten voor elektriciteitscapaciteit, kwaliteit van de voeding, en het vermogen in het residentiële leven garanderen, onderneming productie, openbare plaatsen, enz. worden steeds hoger. De nominale stroom van onderstationapparatuur en besturingsapparatuur neemt ook voortdurend toe; Smart grid is een toekomstgerichte trend, en de intelligentie van energieapparatuur vormt de basis van een slim elektriciteitsnet. Apparatuur voor onderstations, controle apparatuur, en elektrische apparatuur zijn over het algemeen verbonden via de hoofdrail. De intelligentie en standaardisatie van de temperatuurbewaking in het railvoedingssysteem vormen de basis voor de realtime transmissiestatus, temperatuur omstandigheden, en zelfs patrouilledetectie van stroom. In the practical application of busbar trunking, due to long-term operation in the air and the influence of ambient temperature and humidity, thermische uitzetting en krimp, surface scaling, oxidation or corrosion may occur, leading to loose contacts and poor contact. Especially in some large buildings (such as large factories, super high-rise buildings, enz.), where the installation position of busbar trunking cannot be manually monitored, users often neglect the safety management of busbar trunking. Once the temperature of the busbar joints during operation is abnormally overheated, it may lead to fire or major safety and quality accidents, bringing huge and irreparable personal injury and economic and property losses to enterprises.
The bus duct is in a fully enclosed state during operation and is generally in a long-term live state, waardoor dagelijks onderhoud en inspectie erg lastig zijn. Daarom, het is noodzakelijk om de temperatuur van de busverbindingen in het buskanaal te bewaken om de betrouwbaarheid van de werking ervan te verbeteren.

Tijdens de werking van elektrische apparatuur (zoals stroomschakelapparatuur), het is vaak nodig om de bedrijfsstatus van de apparatuur te bevestigen door de temperatuur van verschillende onderdelen en componenten in de elektrische apparatuur te meten. Contacttemperatuurmeting is een veelgebruikte methode, maar in de contacttemperatuurmeetmethode, het is moeilijk om het temperatuurmeetapparaat op de rail te installeren om een betrouwbare verbinding tussen de temperatuursensor en de rail te garanderen, en om een betrouwbare temperatuurmeting te garanderen. Bijvoorbeeld, het wordt bevestigd met luchtvaartspecifieke lijm, but the assembly efficiency is relatively low, and the contact stability and reliability are poor.

The busbar refers to the connecting conductors between the main switch in the distribution cabinet and each branch circuit in the power supply system. The busbar may experience temperature rise during operation due to various reasons, but the temperature of the busbar needs to be controlled within a certain range to ensure the normal operation of the power supply system and prevent accidents. Daarom, temperature monitoring of the busbar is necessary at all times.
Met de voortdurende ontwikkeling van technologie, various wireless bus temperature measurement devices have been used in the daily maintenance of busbars, which are basically powered by batteries, zonne-energie, external power supply, self induction power supply, enz. The device structure is complex.

With the emergence of high-rise buildings and large factories, the electricity consumption in various industries has grown rapidly, and traditional cables can no longer meet the requirements in the transmission of large currents. As a new type of distribution conductor, plug-in bus duct has emerged. Compared with traditional cables, it can fully demonstrate its advantages in high current transmission. Echter, the busbar trunking is exposed to high current and high voltage working environments for a long time. Due to aging, oxidatie, loosening and other reasons, the contact resistance of the busbar contact points and each section of the connection will increase, leading to heating of the busbar, causing safety accidents such as leakage and melting, and even causing fires. Daarom, temperature monitoring of the busbar trunking is particularly important.

Nu, there are several main solutions for temperature monitoring of bus ducts:

1. Infrarood temperatuurmeettechnologie:

The measurement range is large and the accuracy is high, but with cable communication, cables need to be laid and temperature measurement space is required, making it impossible to achieve integrated integration of busbar equipment and online temperature detection. If there is a fault in the line, it will cause temperature measurement failure on a large area of the line.

2. Wireless temperature measurement technology:

Using wireless communication technology for signal transmission, due to distance limitations, it is necessary to set up adapter nodes (repeaters) at a certain distance to amplify the signal; Wireless signals are greatly affected by obstacles and are prone to attenuation; Wanneer draadloze temperatuurmeting is used, the service life of the power supply battery needs to be considered, and a time-based circuit (d.w.z. supplying power to the system at intervals) is adopted. Although this method extends the service life of the battery, it cannot achieve the function of real-time data collection, die een veiligheidsrisico vormt.

3. Gedistribueerde glasvezeltemperatuurmeting

De Gedistribueerde glasvezel temperature measurement system is applied to the busbars and busways of each circuit for real-time temperature monitoring, thereby achieving safety monitoring of the operation of the busbar equipment.

Gedistribueerd glasvezel temperatuurmeetsysteem: It adopts optoelectronic technology, Communicatietechnologie, Microprocessor-technologie, Digitale temperatuurdetectietechnologie, and designed low temperature, Sterk elektrisch veld, en bedieningstechnologie voor vochtige omgevingen. Het kan de temperatuur in verschillende omgevingen afzonderlijk bewaken, Gevaar voor ongevallen vroegtijdig opsporen, and effectively reduce losses. Op hetzelfde moment, it can also provide a large amount of online monitoring data to provide operators with a comprehensive understanding of the outer temperature of the busbar, thereby indirectly inferring the current and load situation in the busbar, and providing power allocation basis for departments.

The significance of Gedistribueerd glasvezel temperatuurmeetsysteem:

1. Safely increasing the current carrying capacity of the circuit;

2. Can achieve periodic state monitoring;

3. Drive external alarms or other emergency systems;

4. Identify hotspots (especially bus joints with potential accident hazards) and other environmental anomalies.

The distributed fiber optic temperature measurement system is a highly intelligent and automated monitoring technology that does not require manual inspection of the monitored area. The monitoring room screen can display temperature information of various points in the entire monitoring area; Wanneer er een oververhittingspunt is, it can sound or light an alarm, and even send it to relevant personnel via mobile phone SMS. Can accurately predict hot spots before accidents occur, with high positioning accuracy, and display the evolution of hot spot temperature. Op hetzelfde moment, the temperature sensor in the distributed fiber optic temperature measurement system has the characteristics of explosion-proof, sterke weerstand tegen elektromagnetische interferentie, goede elektrische isolatie, bliksembeveiliging, hoge precisie, lichtgewicht, klein volume, Corrosie bestendigheid, hoge temperatuurbestendigheid, and no static electricity.
