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. Faodaidh cus teòthachd teintean adhbhrachadh gu furasta, 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, sùil a chumail air atharrachaidhean teòthachd ann an deagh àm agus ceart, agus cuir a-mach rabhaidhean mus tig an teòthachd ro àrd, 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. Bidh an siostam a’ gabhail ri dòigh tomhais teòthachd fulangach a tha mothachail air fiber, cuir às do chunnartan sàbhailteachd an t-siostam sgrùdaidh fhèin agus a’ leasachadh gu mòr na tha ri fhaighinn den t-siostam sgrùdaidh airson sgrùdadh teòthachd cumhachd. Tha an siostam tomhais teòthachd fibre optic seo air a chleachdadh le mòran de ionadan cumhachd agus companaidhean solar cumhachd, a 'lùghdachadh gu mòr na tha de thubaistean teine ​​​​a' tachairt agus a 'coileanadh casg mus tachair e, a rèir bun-bheachd sàbhailteachd “sàbhailteachd an toiseach, stèidhichte air casg” ann an gnìomhachas cumhachd.

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

1. Tha innealan mothachaidh teòthachd dìon-lasrach agus dìon-spreadhaidh.

Bidh am pàirt tomhais teothachd a’ gabhail ri structar uile-snàithleach, a tha dha-rìribh a’ toirt a-mach sgrùdadh teòthachd fulangach. Chan eil e fo chasaid, chan eil e a’ gineadh teas, agus cha bhith e na chunnart sàbhailteachd mar thoradh air cleachdadh an t-siostam mothachaidh.

2. Cruinneas tomhais teòthachd àrd agus freagairt luath.

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 seanailean.

3. Sgrùdadh air-loidhne fìor-ùine.

Monitor the temperature of all measuring points in the substation switchgear continuously for 7×24 uairean, 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. Smachd rabhaidh sgaradh sùbailte.

Tron bhathar-bog sgrùdaidh air a’ choimpiutair àrd, different temperature measurement points can be managed in different zones according to customer needs. Anns an fharsaingeachd, the contacts inside the same switchgear are set as one zone. Set different alarm parameters for each temperature measurement point, leithid rabhadh teòthachd, rabhadh àrdachadh teòthachd, inneal-rabhaidh teòthachd, agus inneal-rabhaidh àrdachadh teòthachd, gus eadar-dhealachadh ceart a dhèanamh eadar teintean fìor agus meallta, cuir às do rabhaidhean meallta agus dearmad.

6. Gnìomh fèin-bhreithneachadh coileanta.

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. Feartan bathar-bog cumhachdach.

Taisbeanadh fìor-ùine den àite, luachan teòthachd, agus atharrachaidhean teothachd anns gach raon sgrùdaidh air an eadar-aghaidh inneal-daonna. Ma tha an coimpiutair àrd uidheamaichte le modal rabhaidh SMS, faodar am fiosrachadh rabhaidh a chuir gu fònaichean-làimhe an luchd-obrach ainmichte gus dèanamh cinnteach gun tèid cunnartan teine ​​​​a làimhseachadh ann an deagh àm. Air a’ choimpiutair àrd, faodar cuideachd fiosrachadh teodhachd eachdraidheil agus clàran rabhaidh a cheasnachadh gus aithisgean gnìomhachd sàbhailteachd a ghineadh.
