ʻO ka mea hana ʻoi loa ʻo Fiber Bragg Grating Thermal Fire Detection System

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. Hiki i ka wela nui ke ho'āla i ke ahi, 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, e nānā i ka hoʻololi ʻana o ka mahana i ka manawa a me ka pololei, a hoʻopuka i nā ʻōlelo aʻo ma mua o ka piʻi ʻana o ka wela, 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. Hoʻohana ka ʻōnaehana i ke ʻano ana ʻana o ke ana wela passive fiber a pau, hoʻopau i nā pōʻino palekana o ka ʻōnaehana nānā ponoʻī a hoʻomaikaʻi nui i ka loaʻa ʻana o ka ʻōnaehana nānā no ka nānā ʻana i ka wela o ka mana.. Hoʻohana ʻia kēia ʻōnaehana ana wela fiber optic e nā mea kanu mana a me nā hui lako mana, hōʻemi nui i ka hiki ʻana mai o nā ulia ahi a loaʻa maoli ka pale ʻana ma mua o ka hiki ʻana mai, e like me ka manao palekana o “palekana mua, hoʻopalekana” i ka ʻoihana mana.

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

1. ʻO nā mea ʻike wela ke kūpaʻa i ka lapalapa a me ka pahū.

Hoʻohana ka ʻāpana ana wela i kahi ʻano fiber āpau, ʻike maoli i ka nānā ʻana i ka wela passive. ʻAʻole i uku ʻia, ʻaʻole hoʻohua wela, a ʻaʻole e hoʻokau i nā pōʻino palekana ma muli o ke kau ʻana o ka ʻōnaehana ʻike.

2. ʻO ke ana wela kiʻekiʻe ka pololei a me ka pane wikiwiki.

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 nā kahawai.

3. ʻO ka nānā ʻana ma ka pūnaewele manawa maoli.

Monitor the temperature of all measuring points in the substation switchgear continuously for 7×24 hola, 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. ʻO ka hoʻomalu ʻana i ka puʻupuʻu hoʻokaʻawale.

Ma o ka polokalamu kiaʻi ma ka lolouila luna, different temperature measurement points can be managed in different zones according to customer needs. ʻO ka maʻamau, the contacts inside the same switchgear are set as one zone. Set different alarm parameters for each temperature measurement point, e like me ka ʻōlelo aʻo wela, ʻōlelo aʻo piʻi wela, hoʻāla wela, a me ka piʻi ʻana o ka mahana, e hoʻokaʻawale pololei ma waena o nā ahi maoli a me nā ahi hoʻopunipuni, hoʻopau i nā ʻōhumu hoʻopunipuni a me nā haʻalele.

6. ʻO ka hana diagnostic ponoʻī piha.

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. Nā hiʻohiʻona lako polokalamu ikaika.

Hōʻike manawa maoli o kahi, nā waiwai wela, a me ka hoʻololi ʻana i ka mahana o kēlā me kēia wahi nānā ma ke kikowaena kanaka-mīkini. Inā hoʻolako ʻia ka lolouila luna me kahi module alarm SMS, hiki ke hoʻouna ʻia ka ʻike alarm i nā kelepona paʻa o ka poʻe i koho ʻia e hōʻoia i ka mālama pono ʻana i nā pōʻino ahi. Ma ka lolouila luna, Hiki ke nīnau ʻia ka ʻikepili wela o ka mōʻaukala a me nā moʻolelo puʻupuʻu e hana i nā hōʻike hana palekana.
