Do you know what to do when the thermal resistance encounters a short circuit? Experts speak out to tell you how to crack

  Generally speaking, you know how to solve when the thermal resistance encounters a short circuit? Experts say that there are cracking methods to deal with. Follow the editor to see how to crack related faults: Generally speaking, the thermal resistance is relatively smooth in the application process, but sometimes there may be failures, which are very common It's open circuit and short circuit. The open circuit is usually caused by the thermal resistance wire being too thin. Let's briefly understand the short circuit and open circuit problems of the thermal resistance.

  Open and short circuits are generally easy to identify with just a multimeter. That is, use the "×1Ω" file of the multimeter to measure. If the measured resistance value is less than R0, it may be a short circuit; if the measurement indication is infinite, it can be determined that the circuit is open. Among them, the short circuit is easier to deal with, as long as the length and thickness of the resistance wire are not affected, find the short circuit and dry it, and strengthen the insulation. If it is an open circuit, the length of the resistance wire must be changed during processing, which will affect the resistance value, so only replace the new resistance body, but if it is repaired by welding, it must be verified after welding before it can be used.

  In addition, if the displayed value of the thermal resistance display instrument is lower than the actual value or the displayed value is unstable, it may be that there is dirt in the protection tube, so the main thing is to remove the dirt. However, if the indication shows a negative value, it may be the thermal resistance wiring error or the thermal resistance short circuit, so as long as the wiring is corrected and the short circuit is handled, it can continue to be used.

  Now, when the thermal resistance encounters a short circuit in the future, do you know how to deal with it? It should be known that the thermal resistance can continue to be used after the short circuit is handled.
