Why do high-voltage power equipment need temperature measurement

Today, with the continuous development of informatization, electric energy has been widely used in various fields. Various power infrastructure that provides electricity energy is widely distributed throughout the country, undertaking the electricity supply in various regions and fields. Miongoni mwao, the power station, as the main infrastructure, its supply of electricity and reliability are related to the basic guarantee of production and life in various regions and fields. There are various high-voltage equipment installed in the power station, such as wiring strips, swichi, nk. These high-voltage equipment are prone to heating problems due to aging, kulegeza, and other issues. When the heating temperature is high, not only does it need to be shut down for maintenance, but it may also cause serious accidents. Katika miaka ya hivi karibuni, multiple power outage and fire accidents have occurred in the fields of power transmission, metallurgy and mining, factories and enterprises, urban power supply, nk., caused by overheating of high-voltage electrical contacts such as high-voltage switch contacts, transformer leads, high-voltage busbars, and high-voltage cable connectors, resulting in huge economic losses. Effective monitoring and alarm of overheating of high-voltage electrical contacts is an urgent requirement for safety production. Kuegemea kwa switchgear ya juu-voltage chini ya voltage ya juu na hali ya juu ya sasa inahusiana kwa karibu na kupanda kwa joto kwa mawasiliano ya kubadili kutengwa.. Wakati wa uendeshaji wa gridi ya nguvu, vibration ya mitambo, wasiliana na mmomonyoko wa udongo, na sababu zingine zinaweza kuzidisha hali ya mawasiliano, kuongeza upinzani wa mawasiliano, kusababisha ongezeko la joto la mahali pa kuwasiliana, kuzidisha oxidation ya uso wa mawasiliano, na kusababisha kulehemu kwa ndani au kutokwa kwa arc kwenye sehemu zisizo huru za mawasiliano, hatimaye kusababisha uharibifu wa vifaa vya umeme, kukatika kwa umeme, au ajali kubwa kama vile moto. Aina hii ya ajali ya kosa la kuzidisha joto sio tu kwa sababu ya shida ya ubora wa swichi ya baraza la mawaziri lenye voltage kubwa yenyewe., lakini muhimu zaidi, kutokana na ukosefu wa mbinu za ufuatiliaji wa ufanisi wa kupanda kwa joto la mawasiliano ya kubadili kutengwa kwa sasa.

Katika uwanja wa vifaa vya baraza la mawaziri la usambazaji wa voltage ya juu na ya chini, kutokana na mahitaji ya mazingira ya kazi ya baraza la mawaziri la usambazaji lililofungwa, mazingira ya kazi ya baraza la mawaziri la usambazaji imefungwa. Pamoja na kuzeeka kwa vipengele mbalimbali vya elektroniki na nyaya, pointi za mawasiliano kati ya vifaa muhimu vya umeme na nyaya zitawaka moto kutokana na upinzani mkubwa wa kuwasiliana unaosababishwa na vumbi, ulegevu, na oxidation. Abnormal heating parts will cause various safety hazards. Hata hivyo, kutokana na mahitaji ya kuziba ya baraza la mawaziri la usambazaji lililofungwa, ni vigumu kwa wakaguzi kuchunguza hali ya kazi ya ndani kupitia njia za kawaida za ukaguzi. Aidha, due to the fact that conventional internal temperature measurement equipment is non-contact temperature measuring instruments and is easily affected by various electromagnetic or environmental factors such as high and low temperatures inside the distribution cabinet, inaccurate temperature measurement and unstable operation may occur. Disadvantages of. Kwa hiyo, kipimo sahihi cha joto mtandaoni cha wakati halisi cha kabati za usambazaji zilizofungwa imekuwa shida ya haraka inayohitaji kutatuliwa katika tasnia..

Traditional temperature measurement methods for high-voltage equipment

With the continuous increase of electricity load, high-voltage isolation switches often experience abnormal temperature rise in switch contacts, miunganisho ya basi, and other parts due to aging, mawasiliano duni, or excessive contact resistance during long-term operation. If not detected and maintained in a timely manner, it will cause serious equipment accidents. Kwa hiyo, solving the problem of switch overheating is the key to preventing such accidents, and achieving real-time temperature monitoring is an important means to ensure the safe operation of high-voltage equipment. Hata hivyo, due to the limitations of high-voltage operation, the heating part of the contact point of the high-voltage isolation switch is difficult to achieve ordinary online temperature measurement for monitoring. The existing temperature measurement technology can only detect which one or some of the high-voltage distribution equipment is in an overheated state, and cannot test which part of the overheated high-voltage distribution equipment is causing the overheat situation. It cannot determine the location of the faulty components, which creates difficulties for equipment maintenance. Installing sensors for temperature monitoring in high-voltage equipment and using infrared thermometers for temperature measurement during inspections are traditional methods of temperature monitoring, which have the problem of low accuracy in temperature measurement results. Kwa sasa, infrared temperature measurement technology is generally used for monitoring in the market. Infrared temperature measurement is easily affected by environmental factors, and there are still significant limitations and difficulties in the application of temperature measurement in dangerous places. The market urgently needs a temperature measurement device that can implement monitoring in dangerous places, with low cost and high reliability.

Kipimo cha joto cha switchgear

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.

Kipimo cha joto cha kivunja mzunguko

The temperature change of the switchgear contacts is the key point for online temperature rise monitoring of the switchgear. Kwa sasa, low-voltage feed switches or other combination switches use circuit breakers or contactors that are modular in design. Dynamic and static contacts are inevitably used in modular design. Hata hivyo, the use of dynamic and static contacts will inevitably increase a fault point because they need to be frequently plugged in and out, and the current here is generally too high. In case of poor contact, it is easy to have high temperature, which can easily burn out the dynamic and static contacts.

Upimaji wa joto la fiber optic katika vituo vidogo

Katika uzalishaji, ajali zinazosababishwa na kuzidisha joto kwa vituo vya kuunganisha vifaa vya umeme husababisha sehemu kubwa ya ajali za jumla za umeme. Ikiwa haijatambuliwa kwa wakati unaofaa, hatari hizo zilizofichwa zitaleta tishio kubwa kwa usambazaji wa nishati salama. Ili kugundua kwa wakati hatari zilizofichwa na kuzuia ajali, ni muhimu kutekeleza ufuatiliaji wa joto la wakati halisi wa mtandaoni na kengele ya akili kwa kila hatua ya uunganisho wa vifaa vya umeme.

Temperature measurement of electrical cabinet

Sababu kubwa ya moto unaosababishwa na makabati ya umeme yenye voltage ya juu ni kwamba mawasiliano ya mtu binafsi au mizunguko katika baraza la mawaziri la umeme la juu-voltage haiwezi kutoa kiasi kikubwa cha joto kutokana na kuzeeka kwa muda mrefu au kuwasiliana maskini., kusababisha joto la juu la ndani, hata kuzidi joto la sehemu ya kuwasha, na hivyo kusababisha moto. Mbali na ukaguzi wa kuimarisha kwa wakati, ni muhimu kuondoa mara moja hatari zilizofichwa katika kukabiliana na pointi hizi zisizo za kawaida na ajali za nip kwenye bud..
