Qhov zoo fiber Bragg Grating Thermal hluav taws kub detection lawv Manufacturer

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. Qhov kub yuav yooj yim ua rau hluav taws kub, 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, saib xyuas kom kub txog kev hloov thaum lub sij hawm thiab yog manner, thiab qhov teeb meem lus ceeb toom ua ntej qhov kub yuav siab heev, 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. Lawv adopts ib fiber sensing passive kub ntsuas txoj kev ntsuas, Eliminating cov kev ruaj ntseg hazards ntawm tus xyuas lawv tus kheej thiab heev txhim kho lub availability ntawm tus xyuas lawv rau cov hwjchim kub xyuas. No fiber optic kub ntsuas lawv siv los ntawm ntau cov hwjchim nroj tsuag thiab hwj huam mov tuam txhab uas muag, Heev txo qhov tshwm sim hluav taws kub thiab tiag achieving tiv thaiv ua ntej nws tshwm sim, hauv kab nrog lub tswvyim kev ruaj ntseg ntawm “kev ruaj ntseg ua ntej, kev tiv thaiv” Nyob rau hauv txoj kev ua lag luam fais fab tuag.

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

1. Kub sensing li yog taws resistant thiab tawg-pov thawj.

Qhov kub ntsuas ib feem ntawm cov qauv fiber qauv, uas tiag twb paub lawm passive kub xyuas. Nws yuav tsis raug them, tsis ua kom muaj cua kub, thiab yuav tsis teeb meem kev nyab xeeb hazards vim lub deployment ntawm lub sensing lawv.

2. Muaj peevxwm ntsuas thiab ceev teb.

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 channels.

3. Lub sij hawm tiag hauv internet xyuas.

Monitor the temperature of all measuring points in the substation switchgear continuously for 7×24 Teev, 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. Yooj ywm partition tswb tswj.

Los ntawm tus xyuas software rau lub computer upper computer, different temperature measurement points can be managed in different zones according to customer needs. Feem ntau, the contacts inside the same switchgear are set as one zone. Set different alarm parameters for each temperature measurement point, xws li kub lus ceeb toom, kub siab tshaj plaws, tswb kub, thiab kub sawv tswb, Yog distinguish ntawm tiag thiab cuav hluav taws kub, tua tswb tswb thiab omissions.

6. Comprehensive self diagnostic function.

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. Haib software nta.

Lub sij hawm tiag zaub ntawm qhov chaw, qhov tseem ceeb, thiab kub hloov txhua qhov chaw ntawm lub human-machine interface. Yog hais tias lub computer upper nruab nrog ib SMS tswb module, Cov ntaub ntawv tswb yuav muab xa mus rau tus neeg ua hauj lwm mobile tes kom paub tseeb tias lub sij hawm tuav hluav taws kub hazards. Nyob rau sab hauv computer, Keeb kwm kub thiab tswb cov ntaub ntawv yuav tau queried los ua kom muaj kev ruaj ntseg lag luam ntaub ntawv.
