18.热电阻断路或短路后怎样处理? 首先将热电阻感温元件从保护管中抽出,用万用表R×1档测量其电阻值,若指针在∞处则为断路,反之指针在零处或小于R_0值则为短路。 (1) 铜热电阻感温元件断路的处理若发现感温元件上漆包线的绝缘漆剥落并有绿锈,说明元件已损坏不能继续使用了,则应报废。若发现元件上的绝缘漆有某些小的脱落,则可以修复继续使用。修复的方法:①在元件的外层找到尾端;②拆开线圈直至断线处;③用电烙铁焊接,然后测量由尾端至引出线是否通
18 thermal resistance circuit or how to deal with after the short circuit? First of all the thermal resistance temperature components from the protection tube, using a multimeter R × 1 file to measure the resistance, if the pointer is at ∞ at the open circuit, while the pointer at zero Or less than the value of R_0 is short-circuited. (1) Treatment of copper thermal resistance temperature sensing circuit breaker If it is found that the insulating paint on the temperature sensing component is peeled off and has green rust, indicating that the component is damaged and can not be used any more, it should be scrapped. If you find that the insulation paint on the components have some small shedding, you can repair to continue to use. Repair method: ① find the outer end of the component; ② open the coil until the broken line; ③ soldering iron, and then measure from the tail to the pin is connected
