The solution of short circuit and open circuit phenomenon of thermal resistance

In general, we use the thermal resistance of cent is still relatively smooth, of course, this does not mean that the thermal resistance will not appear any problems, for example, short circuit and open circuit also is present in both cases, meantime break the ultimate is caused by the thermal resistance wire is too thin, for thermal resistance to present a short circuit and open circuit has the following two cases.

When the thermal resistance shows short circuit or break, it is still relatively simple to judge it, only need to use a multimeter,

How to judge whether the thermal resistance appears short circuit and open circuit? This determination method is still relatively simple, only need to use a multimeter to measure, the multimeter directly to ×1 ω, and the thermal resistance measurement, if the measurement resistance value is less than R0, it shows that the short circuit. If the thermal resistance appears infinite on the measurement indicator, it indicates that the thermal resistance is in a state of disconnection. Short circuit and circuit breaker are more simple to deal with, as long as the wire of the thermal resistance is not affected by the length and thickness, and then find out the short circuit position, and blow dry it completely, and strengthen the insulation.

If the thermal resistance is broken, it is necessary to change the length of the resistance wire during processing, and it will also have a serious impact on the resistance value, so it is a good choice to replace the resistance body, but it needs to use the welding repair method, and after welding, it is necessary to verify the equipment to ensure that it is qualified.
