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. Joto kali linaweza kusababisha moto kwa urahisi, 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, Kufuatilia mabadiliko ya hali ya hewa kwa wakati na kwa usahihi, na kutoa tahadhari kabla ya joto kuwa juu sana, 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. Mfumo unachukua njia zote za kupima joto la nyuzi, kuondoa hatari za usalama wa mfumo wa ufuatiliaji yenyewe na kuboresha sana upatikanaji wa mfumo wa ufuatiliaji wa ufuatiliaji wa joto la nguvu. Mfumo huu wa kipimo cha joto la fiber optic hutumiwa na mimea mingi ya umeme na kampuni za usambazaji wa umeme, kupunguza sana matukio ya ajali za moto na kufikia kuzuia kweli kabla ya kutokea, Kwa mujibu wa dhana ya usalama wa “Usalama wa kwanza, kuzuia oriented” katika sekta ya umeme.

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

1. Vifaa vya kuhisi joto ni sugu ya moto na ushahidi wa mlipuko.

Sehemu ya kipimo cha joto inachukua muundo wote wa nyuzi, ambayo kwa kweli inatambua ufuatiliaji wa joto la baridi. Hakushitakiwa, Haitoi joto, na haitaleta hatari yoyote ya usalama kwa sababu ya kupelekwa kwa mfumo wa kuhisi.

2. Usahihi wa kipimo cha joto la juu na majibu ya haraka.

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 Njia.

3. Ufuatiliaji wa mtandaoni wa wakati halisi.

Monitor the temperature of all measuring points in the substation switchgear continuously for 7×24 Masaa, 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. Udhibiti wa kengele ya kizigeu rahisi.

Kupitia programu ya ufuatiliaji kwenye kompyuta ya juu, different temperature measurement points can be managed in different zones according to customer needs. Ujumla, the contacts inside the same switchgear are set as one zone. Set different alarm parameters for each temperature measurement point, Kama vile tahadhari ya joto, Tahadhari ya kuongezeka kwa joto, kengele ya joto, na kengele ya kuongezeka kwa joto, Tofautisha kwa usahihi kati ya moto wa kweli na wa uwongo, Ondoa kengele za uwongo na upungufu.

6. Kazi kamili ya uchunguzi wa kibinafsi.

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. Vipengele vya programu vyenye nguvu.

Onyesho la wakati halisi wa eneo, thamani ya joto, na mabadiliko ya joto ya kila eneo la ufuatiliaji kwenye kiolesura cha binadamu-machine. Ikiwa kompyuta ya juu ina vifaa vya moduli ya kengele ya SMS, Taarifa ya kengele inaweza kutumwa kwa simu za rununu za wafanyikazi walioteuliwa ili kuhakikisha utunzaji wa hatari za moto kwa wakati unaofaa. Kwenye kompyuta ya juu, Data ya joto ya kihistoria na rekodi za kengele zinaweza pia kuulizwa ili kuzalisha ripoti za operesheni ya usalama.
