Why do switch cabinets need fiber optic grating temperature sensing fire detection systems

The switchgear is a key equipment in the substation, and its internal switch contacts complete the execution of power dispatching. Due to excessive load, aging of contacts, and improper contact, the temperature of the contacts in switchgear can rise. Oormatige temperatuur kan maklik brande veroorsaak, power supply failures, kragonderbrekings, and personal and property losses. The current temperature measurement method in substations mainly uses handheld infrared thermometers to measure temperature, and conducts daily inspections of each switchgear to obtain temperature status information. Each substation urgently needs an online temperature measurement technology that can automatically collect the temperature of each contact in real time, monitor temperatuurveranderinge betyds en akkuraat, en waarskuwings uit te reik voordat die temperatuur te hoog word, so that managers have sufficient time to take corresponding measures to avoid power outages and fires.

Fiber optic temperature sensing technology can develop a fiber optic grating temperature sensing fire detection system, which can monitor the temperature of switchgear in real time and provide early warning and alarm. Die stelsel neem 'n passiewe temperatuurmetingsmetode vir alle veselwaarneming aan, die veiligheidsgevare van die moniteringstelsel self uit te skakel en die beskikbaarheid van die moniteringstelsel vir kragtemperatuurmonitering aansienlik te verbeter. Hierdie optiese veseltemperatuurmetingstelsel word deur baie kragsentrales en kragvoorsieningsmaatskappye gebruik, die voorkoms van brandongelukke aansienlik verminder en werklik voorkoming bereik voordat dit voorkom, in ooreenstemming met die veiligheidskonsep van “Veiligheid eerste, Voorkoming georiënteerd” in die kragbedryf.

What are the main functions of the fiber Bragg grating temperature measurement system host

1. Temperatuurwaarnemingstoestelle is vlambestand en ontploffingsbestand.

Die temperatuurmetingsdeel neem 'n veselstruktuur aan, wat werklik passiewe temperatuurmonitering besef. Dit word nie gehef nie, genereer nie hitte nie, en sal geen veiligheidsgevare inhou as gevolg van die ontplooiing van die waarnemingstelsel nie.

2. Hoë temperatuur meet akkuraatheid en vinnige reaksie.

The temperature measurement host has high temperature resolution and high temperature measurement accuracy. The full channel scanning time is short, with a temperature detection time of about 2 seconds for 16 Kanale.

3. Intydse aanlyn monitering.

Monitor the temperature of all measuring points in the substation switchgear continuously for 7×24 Uur, and regularly save the temperature measurement data to provide auxiliary data for the health monitoring of each switchgear.

4. Accurate spatial positioning.

Fiber Bragg grating temperature sensing corresponds to each measurement point position, and each sensor has global uniqueness. The upper computer monitoring software can accurately locate the location of the sensor that triggered the alarm.

5. Buigsame partisie alarm beheer.

Deur die moniteringsagteware op die boonste rekenaar, different temperature measurement points can be managed in different zones according to customer needs. Algemeen, the contacts inside the same switchgear are set as one zone. Set different alarm parameters for each temperature measurement point, soos temperatuurwaarskuwing, Waarskuwing vir temperatuurstygings, temperatuur alarm, en temperatuurstyging alarm, om akkuraat te onderskei tussen werklike en valse brande, skakel vals alarms en weglatings uit.

6. Omvattende selfdiagnostiese funksie.

Each temperature sensor in this system has wavelength uniqueness, and the system database can remember its precise location. At the same time as each temperature measurement, the system performs self testing and diagnosis to detect sensor faults in real time for timely repair and maintenance.

7. Kragtige sagteware-funksies.

Intydse vertoning van die ligging, temperatuur waardes, en temperatuurveranderinge van elke moniteringsarea op die mens-masjien-koppelvlak. As die boonste rekenaar toegerus is met 'n SMS-alarmmodule, Die alarminligting kan na die aangewese personeel se selfone gestuur word om tydige hantering van brandgevare te verseker. Op die boonste rekenaar, Historiese temperatuurdata en alarmrekords kan ook gevra word om veiligheidsverslae te genereer.
