一、大功率水泥电阻的修复彩色电视机中的大功率水泥电阻的损坏,大多是开路性损坏。若用万用表判断出是开路,请不要随便丢弃,这种电阻通常可以修复。具体方法是:用锤子轻轻将电阻瓷质外壳敲碎,便可看到绕在瓷芯上的电阻丝,通常开路点为电阻丝端头脱焊(少数中间断裂者,可取一段与原电阻阻值相同的电炉丝代替电阻丝),只须将其重新焊牢,再用标号较高的水泥包裹至与原电阻相近的直径,待水泥晾干
First, the repair of high-power cement resistance Color TV in the power of cement damage, mostly open-circuit damage. If using a multimeter to judge is open, please do not throw it away, this resistance can usually be repaired. The specific method is: gently hammer the ceramic shell knocking resistance, we can see around the core of the resistance wire, usually the end of the open circuit resistance wire tip off (a few intermediate break, it is desirable to a period of resistance with the original Resistance of the same electric wire instead of resistance wire), just to re-weld the prison, and then use the higher cement wrapped with the original resistance similar to the diameter of the cement to be dry
