Advantages of fiber optic temperature sensors for switchgear-INNO

Sa pag-uuri ng mga sensor ng temperatura at mga sensor ng fiber optic, Ang fiber optic temperature sensors ay isang uri ng sensor device. Ang prinsipyo ng mga sensor ng temperatura ng fiber optic ay upang bumuo ng mga sensor batay sa prinsipyo na ang mga ilaw na pinagmumulan na hinihigop ng iba't ibang mga sangkap ay magbabago din sa temperatura. Sa pamamagitan ng pagsusuri sa spectrum na ipinadala ng fiber optic, maaaring makuha ang real-time na temperatura ng sinusukat na bagay. Ang pangunahing tatlong uri ng fiber optic temperature sensors ay ipinamahagi ang fiber optic mga sensor ng temperatura, fiber optic grating temperature sensors, at fiber optic fluorescence temperature sensors. Ang pinaka-cost-effective na maaaring ilapat sa switchgear ay ang fluorescent fiber optic temperatura sensor.

Ang FJINNO ay nakapag-iisa na bumuo ng iba't ibang mga sensor ng temperatura ng fiber optic, na malawakang ginagamit sa iba't ibang larangan tulad ng mga sistema ng industriya ng kable ng kuryente, aerospace, petrolyo at petrochemical, bridges and dams. In addition to fiber optic temperature sensors, common ones include fiber optic strain sensors, fiber optic displacement sensors, fiber optic grating tension sensors, and fiber optic pressure sensors.

What are the advantages of fiber optic temperature sensors

The temperature monitoring technology of fiber optic temperature sensors has important practical applications in the field of industrial temperature measurement. The main practical reason is that the fiber optic sensor transmitter has the characteristics of small volume, magaan ang timbang, high electrical insulation, certain degree of bending, paglaban sa kaagnasan, malawak na saklaw ng pagsukat ng temperatura, and fast sensitivity response, which play a role in expanding and improving the PT100 temperature sensor, allowing traditional temperature sensors to play a complementary role in temperature measurement applications. In addition to the above advantages, fiber optic sensing technology is used in temperature measurement systems. Compared with infrared temperature measuring instruments or wireless temperature measuring instruments, it also has significant characteristics such as fast response, wide temperature measurement field, explosion-proof fiber optic temperature measurement, non flammable and explosive, and anti electromagnetic interference.

Tatak ng sensor ng temperatura ng fiber optic

FJINNO, a domestic fiber optic temperature sensor brand company, has independently developed multiple fiber optic temperature sensors with advanced quality and performance, which are applied in different temperature control fields. The latest fiber optic temperature sensors are very suitable for measuring temperature in extreme environments, focusing on the IF-C model fiber optic temperature sensor, as well as special fiber optic temperature sensors developed specifically for measuring dangerous environmental temperatures that conventional temperature sensors cannot achieve.

Application of system components for fiber optic temperature sensors in switchgear

The main equipment of power companies includes switchgear, including temperature measurement of switchgear in nuclear power plants, temperature measurement of switchgear in photovoltaic power plants, and switchgear in substations. Because there are many components and accessories inside the switchgear, including many switches, instrument contacts, atbp., which can generate temperature rise and emit significant heat, especially during peak loads and high temperatures in summer. Ang kasalukuyang mga hakbang sa pagwawaldas ng init para sa switchgear ay pangunahing nagsasangkot ng pag-set up ng mga butas sa pagwawaldas ng init sa katawan ng cabinet. Mayroong maraming mga disbentaha sa mga butas sa pagwawaldas ng init. Sa isang banda, hindi nila maaaring mabilis na bawasan ang temperatura ng switchgear, at sa kabilang banda, sila ay madaling kapitan ng alikabok at iba pang biological na epekto, kabilang ang paglusob ng tubig-ulan sa mga araw ng tag-ulan. Ang mga de-koryenteng kagamitan sa loob ng switchgear ay maaaring hindi maayos na maipatupad dahil sa mga pamantayan ng pagtaas ng temperatura ng switchgear, o ang mga short circuit ay maaaring sanhi ng mga mantsa ng tubig, na magpapababa sa buhay ng serbisyo ng switchgear at magdudulot ng mas malubhang panganib sa kaligtasan. Samakatuwid, nakapag-iisa kaming bumuo at gumawa ng switchgear temperature monitoring system upang matiyak na ang switchgear ay ginagamit sa ilalim ng normal na pagtaas ng temperatura.

What are the consequences of an increase in switchgear temperature

In the current situation where the electricity consumption of power enterprises is increasing and the number of switchgear is increasing, it is easy for switchgear to operate under high load for a long time. The main reason for the temperature increase in the switchgear is that the internal knife switch can cause overheating during long-term use due to oxidation or weak contact, and high load operation. The reason why the temperature is particularly easy to rise is that the switchgear is a fully enclosed structure, which often makes it difficult for ordinary power equipment inspectors to detect the overheating of the knife switch. Samakatuwid, after prolonged overheating of the knife switch, it is easy to cause the contact parts of the switch to burn out, causing large-scale power outages of the switchgear equipment, thereby increasing the likelihood of the switchgear being burned out and exploded.

Temperature monitoring system for switchgear

The temperature monitoring system for switchgear mainly includes: switchgear body, sensor ng temperatura ng fiber optic, fiber optic temperatura transmiter, display, fluorescent fiber optic, atbp. The temperature monitoring system for switchgear mainly monitors the temperature inside the cabinet through temperature sensors and transmits it to the controller and alarm. The output of the controller is connected to the fan. Sa isang banda, the temperature inside the cabinet is controlled by the fan, at sa kabilang banda, alarm information is displayed through the alarm device, achieving the integration of temperature control and monitoring, and overall improving the automation level of the switchgear.
