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. Haddan tashqari harorat osongina yong'inga olib kelishi mumkin, 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, harorat o'zgarishini o'z vaqtida va to'g'ri kuzatib borish, va harorat juda yuqori bo'lishidan oldin ogohlantirishlarni bering, 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. Tizim to'liq tolali sensorli passiv haroratni o'lchash usulini qabul qiladi, monitoring tizimining xavfsizlik xavfini bartaraf etish va quvvat harorati monitoringi uchun monitoring tizimining mavjudligini sezilarli darajada yaxshilash. Ushbu optik tolali haroratni o'lchash tizimi ko'plab elektr stantsiyalari va elektr ta'minoti kompaniyalari tomonidan qo'llaniladi, yong'in hodisalari sodir bo'lishini sezilarli darajada kamaytirish va ularning paydo bo'lishidan oldin ularning oldini olishga erishish, xavfsizlik kontseptsiyasiga muvofiq “birinchi navbatda xavfsizlik, oldini olishga qaratilgan” energetika sanoatida.

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

1. Haroratni o'lchash moslamalari olovga chidamli va portlashdan himoyalangan.

Haroratni o'lchash qismi barcha tolalar tuzilishini qabul qiladi, bu haqiqatan ham passiv harorat monitoringini amalga oshiradi. Undan undirilmaydi, issiqlik hosil qilmaydi, va sensorli tizimning o'rnatilishi tufayli hech qanday xavfsizlikka xavf tug'dirmaydi.

2. Yuqori haroratni o'lchash aniqligi va tezkor javob.

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 kanallar.

3. Haqiqiy vaqtda onlayn monitoring.

Monitor the temperature of all measuring points in the substation switchgear continuously for 7×24 soat, 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. Moslashuvchan bo'lim signalini boshqarish.

Yuqori kompyuterda monitoring dasturi orqali, different temperature measurement points can be managed in different zones according to customer needs. Umuman, the contacts inside the same switchgear are set as one zone. Set different alarm parameters for each temperature measurement point, harorat haqida ogohlantirish kabi, harorat ko'tarilishi haqida ogohlantirish, harorat signalizatsiyasi, va harorat ko'tarilishi signalizatsiyasi, haqiqiy va yolg'on yong'inlarni aniq ajratish, noto'g'ri signallar va kamchiliklarni bartaraf etish.

6. Kompleks o'z-o'zini diagnostika funktsiyasi.

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. Kuchli dasturiy ta'minot xususiyatlari.

Joylashuvni real vaqtda ko'rsatish, harorat qiymatlari, va inson-mashina interfeysidagi har bir monitoring hududining harorat o'zgarishi. Agar yuqori kompyuter SMS signal moduli bilan jihozlangan bo'lsa, Yong'in xavfini o'z vaqtida bartaraf etishni ta'minlash uchun signal ma'lumotlari belgilangan xodimlarning mobil telefonlariga yuborilishi mumkin.. Yuqori kompyuterda, tarixiy harorat ma'lumotlari va signal yozuvlari xavfsizlik operatsiyasi hisobotlarini yaratish uchun ham so'ralishi mumkin.
