Je, ni mfumo mzuri wa kipimo cha joto kwa wavunjaji wa mzunguko

Kwa nini wavunja mzunguko hutumia mifumo ya ufuatiliaji wa joto

Maendeleo ya tasnia ya kebo ya umeme ni ya haraka sana, na mifumo mingi ya udhibiti wa vituo vya usambazaji imeanza mitambo ya viwandani, ufuatiliaji na ufuatiliaji wa mfumo wa kidijitali wa mawasiliano, kufanya matengenezo na matumizi ya vifaa vya usambazaji wa nishati salama; Wavunjaji wa mzunguko katika switchgear hutumiwa kwa kawaida wakati wa operesheni, ambayo inaweza kusababisha urahisi kuvaa kwenye mawasiliano ya nguvu na tuli ya wavunjaji wa mzunguko, vifungo vilivyolegea kwenye upau wa basi wa kituo, na matukio mengine; Ikiwa mzunguko wa mzunguko haufanyiki ufuatiliaji wa joto, inawezekana kuzalisha joto la juu la joto, ambayo inaweza kusababisha kuzeeka kwa vipengele vya insulation ya switchgear na uwezekano wa kusababisha moto au uharibifu wa vifaa vya nguvu.

FJINNO’s fluorescent fiber optic temperature measurement system for switchgear circuit breakers effectively monitors and controls the temperature of the circuit breakers, making it convenient for on-site personnel to maintain the distribution cabinet. Reducing user losses and improving product maintenance and service life have achieved good economic benefits.

Temperature monitoring instrument for switchgear circuit breakers

The temperature operation monitoring of high-voltage switchgear is an important way to ensure the safe operation of the power system. Hata hivyo, traditional circuit breaker monitors only monitor the electrical parameters (voltage, ya sasa, na nguvu) in real time. Hata hivyo, due to the limitations of high voltage, measurement point positions, and strong electric field interference, joto la mawasiliano halifuatiliwi kwa wakati halisi mtandaoni na vifaa vya ufuatiliaji wa jumla.

Ufuatiliaji wa joto la nyuzi za fluorescent chombo cha kuvunja mzunguko

Siku hizi, kubadili kabati zote ni aina ya gari ndogo, kwa sababu mzunguko wa mzunguko na baraza la mawaziri la kubadili huunganishwa na plugs. Uzalishaji duni, usafiri, na ufungaji wa gari ndogo na kubadili baraza la mawaziri inaweza kusababisha kuwasiliana maskini na kuongezeka kwa upinzani wa mawasiliano, kusababisha ongezeko la joto la mawasiliano au hata kuwaka, na kukatika kwa umeme. Matukio haya ya kupanda kwa halijoto yanaonekana hasa katika kabati za kubadili za sasa za juu kama vile kabati zinazoingia, ambazo zina athari kubwa kwa kivunja mzunguko. Uunganisho kati ya mawasiliano ya kubadili high-voltage na basi ni daima katika voltage ya juu, joto la juu, uwanja wa sumaku wa juu, na mazingira yenye nguvu sana ya mwingiliano wa sumakuumeme. Traditional temperature measuring instruments such as thermocouples and infrared thermometers are easily affected by these factors, making it difficult to accurately measure these positions and thus unable to truly obtain the high voltage switch cabinet. The actual temperature value, resulting in local overheating inside the equipment but still operating at high load, The kipimo cha joto la fiber optic device for monitoring the temperature of the contact arm of the circuit breaker can monitor the temperature of the contact arm of the circuit breaker online and detect thermal faults in the circuit breaker contact arm as soon as possible.

The temperature measurement methods for circuit breakers include infrared temperature measurement, kipimo cha joto la upinzani wa joto, and fiber optic temperature measurement. Infrared temperature measurement is a direct measurement of an object’s surface by manually holding an infrared gun, which is easily affected by environmental temperature. Its biggest disadvantage is that it must be operated manually and cannot achieve online monitoring. Thermal resistors and thermocouples both require metal wires to transmit signals, which cannot solve insulation problems.

The fiber optic temperature detector for circuit breakers can monitor the temperature measurement of high voltage and high current electrical appliances. Kwa mfano, for the temperature detection of the contact of 6-35kV vacuum circuit breakers, fluorescence fiber optic thermometers are mostly used. The fluorescence fiber optic thermometers consist of transmission fibers, sensorer za joto la fiber optic, wasambazaji wa joto la nyuzi macho, LCD display screens, na vipengele vingine.
