Kakšne so slabosti toplotnih uporov v hidroenergetski industriji? Kaj naj storimo, če nanje vplivajo iskrice ali loki?

In the hydropower industry, unstable performance and poor reliability of temperature measuring thermal resistors are very common problems. The temperature signal false alarm caused by unstable performance has been troubling the operators and maintenance personnel of the power plant. In severe cases, it can cause the unit to shut down due to accidents, which will have an immeasurable impact on the life of the unit and the safety of the power Grid . Zato je zelo nujno analizirati vzroke temperaturnih merskih uporov in izboljšati dolgoročno stabilnost in zanesljivost temperaturnih merilnih uporov .
Because the electron density of thermal resistors is different, a certain amount of electron diffusion is generated. When they reach a certain balance, the potential formed and the size of the contact potential depend on the material properties of the two different conductors and the temperature of their contact points. The thermocouples currently used internationally have a standard specification. However, the electrical signal of the Termoelement zahteva, da se prenese posebna žica, ki ji rečemo kompenzacijska žica . Različni termoelementi potrebujejo različne kompenzacijske žice, njihova glavna funkcija pa je, da se povežete s termoelementom, da se referenčni konec termoelementa oddalji od napajanja .
Eksplozivni mešani plin v lupini toplotnega upora, vplivajo na iskre ali loki . Popravilo odklopnika telesa uporov neizogibno spremeni dolžino uporne žice in vpliva na vrednost upora ., če mora biti popravilo, da bo kalibrato telo {2}, ki bo bolje nadomestiti telo {2} {2} Uporabljena . Sprememba izmerjene temperature se neposredno meri s spremembo vrednosti upornosti toplotnega upora . Zato je sprememba upora različnih žic, kot je žica svinčene uporov, vplivala na merjenje temperature .. Običajno se uporablja pri nadzoru industrijskega procesa .
When the explosion of the thermal resistor caused by sparks or arcs is confined to the junction box, the production site will not cause an explosion, and it is close to the end face of the thermometer. Compared with general axial thermal resistors, it can more accurately and quickly reflect the actual temperature of the measured end face, and is suitable for measuring the end face temperature of bearings and other parts.
Kakšne so prednosti in slabosti uporabe toplotnih uporov v hidroenergetski industriji?
Življenje ljudi se pogosto uporablja . Z razvojem tehnologije se toplotni upori ne uporabljajo samo v vsakdanjem življenju, ampak imajo tudi zelo pomembno vlogo v hidroenergijski industriji .
Prednosti toplotnih uporov v hidroenergetski industriji: Z razvojem industrije so toplotni upori pogosto uporabljeni pri meritvah industrijske proizvodnje . termistorji so najpomembnejši senzorji v hidroelektrarnih rastlinah. safely. Disadvantages of thermal resistors in the hydropower industry: In the hydropower industry, unstable performance and poor reliability of thermometers are very common problems. False alarms of temperature signals due to unstable performance have always troubled the operators and maintenance personnel of power plants. In severe cases, they can cause unit accidents and Izklopi, ki bodo imeli neizmerno vpliv na življenjsko dobo enote in varnost električnega omrežja . Zato je zelo nujna naloga analizirati vzroke napak v termometrih in izboljšati dolgoročno stabilnost in zanesljivost termometrov .
