技术领域technical field

本发明涉及电力电缆，尤其涉及一种电缆检测器。The invention relates to power cables, in particular to a cable detector.

背景技术Background technique

目前在生产过程中对线芯的检测大多是采用数字万用表来实现，用数字万用表的电阻档位去测量电阻值进行判断缆芯是否存在断点或其质量是否达标；往往因在生产现场没有固定的检测工作台，需手持测量，测量芯线要和数字万用表的表笔相连接，每测量一根就要观看一下万用表上的实际显示数值，频繁的工作有时不慎，就会造成数字万用表脱落摔到地上，造成仪表损坏，经常出现误判现象，工作效率低。At present, in the production process, the detection of the cable core is mostly realized by using a digital multimeter. Use the resistance gear of the digital multimeter to measure the resistance value to judge whether there is a breakpoint in the cable core or whether the quality is up to standard; The detection workbench needs to be measured by hand, and the measuring core wire should be connected with the test leads of the digital multimeter. Every time you measure one, you should watch the actual display value on the multimeter. Frequent work and sometimes careless work will cause the digital multimeter to fall off. If it falls to the ground, the instrument will be damaged, misjudgment often occurs, and the work efficiency is low.

检测时，将两个接线端点分别连接电缆的两个节点，若此时发光二极管和/或蜂鸣器不工作，即不发光和/或不报警，则该电缆两节点间不存在断点，反之则电缆存在断点；When testing, connect the two terminal points to the two nodes of the cable respectively. If the light-emitting diode and/or the buzzer does not work at this time, that is, does not emit light and/or does not alarm, then there is no breakpoint between the two nodes of the cable. Otherwise, there is a breakpoint in the cable;

根据电缆型号，将电位器调至特定档位，若发光二极管和/或蜂鸣器工作，即发光和/或报警，则说明该电缆电阻大于国标要求，属于不合格电缆；反之则属于合格电缆。According to the cable model, adjust the potentiometer to a specific position. If the light-emitting diode and/or buzzer work, that is, light up and/or alarm, it means that the cable resistance is greater than the national standard requirement, and it is an unqualified cable; otherwise, it is a qualified cable. .
