Katere so pogoste napake električnih grelnikov? Kako jih preprečiti?

During the use of electric heaters, if there is a short circuit in the internal system, it will not be possible to ensure the normal use of the equipment if it is not eliminated in time. In serious cases, it will cause damage to the internal system, thus causing serious losses to users and enterprises. Therefore, internal faults should be avoided as much as possible during use. If they unfortunately occur, effective measures je treba sprejeti pravočasno, da jih rešite .

Na splošno velja, da je napajanje AC znotraj grelnika v glavnem nadzorovano s stiki instrumenta za nadzor temperature . Ko je temperatura nižja od nastavljene temperature, se stiki regulacijskega instrumenta priključijo in temperatura se dvigne; Ko je temperatura višja od nastavljene temperature, se stiki odklopijo in temperatura pade, kar zagotavlja, da grelnik deluje v določenem temperaturnem območju .

If the heater burns out, the staff will not be able to determine whether it is a normal power outage after the temperature rises or a power outage caused by a fault. According to the thermal inertia of the equipment, the internal temperature of the heater needs to be delayed for a period of time before it can drop. When the operator finds that the product is unqualified, he knows that there is a fault, which has already caused odpadki in resno vplivajo na kakovost izdelka .

Kot odgovor na zgoraj omenjene skupne napake je priporočljivo, da je grelnik opremljen z napravo za zaznavanje kratkega stika, tako da lahko, ko grelnik izgubi napajanje, naprava razumno zazna vzrok in izvede bolj pravilne odzivne ukrepe za zmanjšanje nepotrebnih izgub za uporabnike .
