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. Prekomerna temperatura lahko zlahka povzroči požar, power supply failures, power outages, 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, pravočasno in natančno spremljajte temperaturne spremembe, in izdajanje opozoril, preden temperatura postane previsoka, 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. Sistem sprejme metodo pasivnega merjenja temperature z zaznavanjem vseh vlaken, odprava varnostnih tveganj samega nadzornega sistema in znatno izboljšanje razpoložljivosti nadzornega sistema za spremljanje temperature moči. Ta sistem za merjenje temperature optičnih vlaken uporabljajo številne elektrarne in podjetja za oskrbo z električno energijo, močno zmanjša pojav požarnih nesreč in resnično doseže preprečevanje, preden se zgodi, v skladu z varnostnim konceptom “Varnost na prvem mestu, usmerjena v preprečevanje” v elektroenergetiki.

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

1. Naprave za zaznavanje temperature so odporne proti ognju in eksploziji.

Del za merjenje temperature ima strukturo vseh vlaken, ki resnično uresničuje pasivno spremljanje temperature. Ne zaračuna se, ne proizvaja toplote, in ne bo predstavljal nobenih varnostnih tveganj zaradi uporabe senzorskega sistema.

2. Visoka natančnost merjenja temperature in hiter odziv.

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 Kanalov.

3. Spletno spremljanje v realnem času.

Monitor the temperature of all measuring points in the substation switchgear continuously for 7×24 Ur, 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. Prilagodljiv nadzor alarma na particiji.

Prek programske opreme za spremljanje na zgornjem računalniku, different temperature measurement points can be managed in different zones according to customer needs. Splošno, the contacts inside the same switchgear are set as one zone. Set different alarm parameters for each temperature measurement point, na primer opozorilo o temperaturi, Opozorilo o dvigu temperature, temperaturni alarm, in alarm za dvig temperature, natančno razlikovati med resničnimi in lažnimi požari, odpraviti lažne alarme in opustitve.

6. Celovita samodiagnostična funkcija.

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. Zmogljive funkcije programske opreme.

Prikaz lokacije v realnem času, temperaturne vrednosti, in temperaturne spremembe vsakega območja spremljanja na vmesniku človek-stroj. Če je zgornji računalnik opremljen z alarmnim modulom SMS, Informacije o alarmu se lahko pošljejo na mobilne telefone določenega osebja, da se zagotovi pravočasno obravnavanje nevarnosti požara. Na zgornjem računalniku, Zgodovinske podatke o temperaturi in zapise alarmov je mogoče poizvedovati tudi za ustvarjanje poročil o varnostnem delovanju.
