Mtengenezaji bora wa vifaa vya kupima joto kwa switchgear nchini China

Katika miaka ya hivi karibuni, matumizi makubwa ya vifaa vya nyumbani yamesababisha ongezeko kubwa la matumizi ya umeme mijini na vijijini, ambayo pia imeweka mahitaji ya juu zaidi ya usalama na kutegemewa kwa usambazaji wa umeme katika gridi ya umeme. Katika gridi ya nguvu, switchgear ya juu-voltage ina jukumu mbili katika kufunga na kukata nyaya za umeme, pamoja na kulinda usalama wa mfumo. Kutokana na kuongezeka kwa kasi kwa idadi ya maombi ya switchgear high-voltage katika mtandao wa usambazaji, takwimu zinaonyesha kuwa hadi mwisho wa miaka ya 1990, kulikuwa na zaidi ya 270000 swichi za usambazaji zinazofanya kazi katika mfumo wa nguvu wa kitaifa, ambayo iliongezeka maradufu ikilinganishwa na mwaka uliopita. Hata hivyo, the high-voltage switchgear in the 10kV distribution network is affected by various factors such as daily operation, external damage, and overloaded lines, resulting in a huge proportion of overheating faults. Especially during peak summer and high load periods of the power grid every year, the overall damage caused by overheating of the contacts inside the switchgear often occurs. Wakati wa operesheni ya muda mrefu, the contacts and busbar connections of the switch may heat up due to aging or increased contact resistance. Prolonged overheating can cause deterioration of the insulation material, leading to malfunctions and even explosions in the switchgear. Ultimately leading to the occurrence of fires or large-scale power outages.

Temperature measurement method for switchgear

A. Manual inspection

Opening the cabinet for inspection is time-consuming and labor-intensive, with low work efficiency. Aidha, it is very inconvenient to inspect high-voltage, especially ultra-high voltage switchgear, and it also poses certain risks.

B. Kipimo cha joto cha infrared

The advantage of using a mobile infrared thermometer to monitor the switchgear at a certain distance is convenience, but the disadvantage is that it is time-consuming and labor-intensive, and requires timed and fixed points, na kipimo cha joto is not accurate.

c. Upimaji wa joto la fiber optic

The fluorescent fiber optic thermometer for switchgear can effectively avoid the drawbacks of the above temperature measurement methods, with accurate temperature measurement and no need for manual monitoring, and can measure temperature 24 masaa kwa siku.

The switchgear thermometer is used to detect the temperature of various devices inside the switchgear, and there are many different thermometer brands and distributors on the market.

As manufacturers pay more and more attention to the temperature measurement needs of switchgear, there are naturally more and more instruments for detecting switchgear, and switchgear temperature sensors are one of them. Hata hivyo, there are many manufacturers of switchgear temperature sensors in the market, so how to choose the appropriate switchgear temperature measurement products.

1. Choose appropriate temperature measurement products

For the most suitable fluorescent fiber optic temperature measurement for switchgear, fiber optic iliyosambazwa temperature measurement is suitable for cable trenches or tunnels, and temperature control systems for alarms are suitable for using fiber optic grating fire detectors, nk.

2. Accuracy of temperature measurement products

Bidhaa ya kipimo cha joto kwa swichi lazima iweze kupima joto kwa usahihi, vinginevyo kuna hatari kwa sekta ya nishati. Ikiwa kipimo cha joto sio sahihi, itaathiri uendeshaji wa kawaida wa switchgear.

3. Utulivu wa bidhaa za kipimo cha joto

Bidhaa ya kupimia joto lazima iweze kufanya kazi kwa utulivu kwa muda mrefu na haiwezi kufanya kazi vibaya baada ya muda., ambayo inaonyesha kuwa ubora wa bidhaa hauko kwenye kiwango.

4. Huduma ya baada ya mauzo kwa bidhaa za kipimo cha joto

Baada ya kuuza chombo cha kupima joto, mtengenezaji lazima kuchukua jukumu kamili kwa ajili ya bidhaa, kuhakikisha kuwa maagizo ya matumizi na matengenezo ya bidhaa yapo.
