Method and device for conductor diameter check of electric cable core group
专利汇可以提供Method and device for conductor diameter check of electric cable core group专利检索，专利查询，专利分析的服务。并且PURPOSE: To detect an abnormal cable conductor which is broken or causes contact while taking the measurement of a conductor diameter accurately and rapidly by finding and checking the conductor-resistance-value ratio of a cable core group to some cores of the group.
CONSTITUTION: The block diagram shows the constitution of a check unit and wind starting terninal 5 and the wind ending terminal of core L of a quad to be measured are shown. In case of the breaking of wire, conductor resistance R is infinite and then any voltage (v) is developed. In this case, A/D converter 10 puts buzzer 17 into continuous operation and lamp 18 displays the core number, thereby immediately processing the breaking of wire. On the other hand, when contact is caused, conductor resistance Rn of the core in the contact state is found decreasing remarkably through conductor resistance measurement except where the contact point is very close to wind starting terminal 5. This can also be found by digital display unit 31 and conductor resistance rate Rn also deviates from reference rate Po, which can be detected.
