Abstract
Due to the quantity of the communication-cable conductors is large, it is time-consuming, laborious and inefficient to adopt the traditional detecting method. Its character is as follows: after completing the conductors and screen voltage-resistance detection and the voltage-resistance detection between the main and vice color lines, it divided the total conductors into n bit groups whose conductor pair number is equal, and each of the groups has m conductor pairs, and then it at first detects the voltage-resistance performance between the conductor pairs of each group and every one of the rest, and in succession detects the voltage-resistance performance between the conductor pair sin every group, and its program is that it arbitrarily extracts a conductor pair from each group respectively to compose a conductor pair group, then detects the voltage-resistance performance between each conductor pair group.

3, for reaching preceding two quality standards, the 3rd step, detect each core in this root cable to withstand voltage properties whether reach quality standards.
Running program is as follows: 1. from 800 pairs of cores of this root cable, core of arbitrary extracting is docked to the positive terminal of withstand voltage instrument, with 799 remaining cores to being connected to the negative pole end of withstand voltage instrument, detect this core to the withstand voltage properties right to all the other cores, if test reaches withstand voltage standard index, this core is to qualified, do not reach index this to core to for defective; 2. again from remaining 799 core centerings, core of arbitrary extracting is right, receive the positive terminal of withstand voltage instrument, with all the other 798 cores to being connected to the negative pole end of withstand voltage instrument, detect this to core pair and remaining core to withstand voltage properties, it is qualified to reach withstand voltage quality standard, otherwise be defective, detect in regular turn by said procedure, last two remaining cores are right up to testing, and the testing of this root cable is just accused and finished.Whether qualified, will do 801 tests at most if detecting a cable quality.Be not difficult to find out that the quality inspection work of cable is quite heavy.
Summary of the invention
The objective of the invention is to: according to the state quality standard of cable, it is few to provide a kind of detection streamer core to do the voltage-withstand test number of times, used detection time is short, can improve testing efficient greatly, again the new method for detecting voltage-resistance of communication cable that can reduce labor intensity.
The objective of the invention is that following trace routine realizes by carrying out:
A kind of new method for detecting voltage-resistance of telecommunication cable, withstand voltage whether reaching quality standards between at first detection streamer core and skin shield, then detect withstand voltage whether the reaching quality standards between mass-tone core and parachrome core, if it is all qualified that this two step is detected, the 3rd the step to detect each core between withstand voltage properties whether reach quality standards, it is characterized in that: this detecting operation program is carried out by following order: 1. total core logarithm order mn of this root cable, be divided into n the big group that the core logarithm equates, each big group has core logarithm order m, then with one of them big group m core to being connected to the positive terminal of withstand voltage instrument, all the other (n-1) individual big group core to being connected to withstand voltage instrument negative pole end, do voltage-withstand test, if reach withstand voltage quality standard, the withstand voltage properties between core of this big group pair and all the other each big group is just qualified; 2. then from (n-1) of remainder individual big group, extract a big group core again and be docked to withstand voltage instrument positive terminal, with all the other (n-2) individual big group of core to being connected to the negative pole end of withstand voltage instrument, detect this core of big group pair and remaining each big group of core to the pressure withstand voltage properties whether reach quality standards, press said procedure, big group of each extraction is done the withstand voltage properties test to big group of being left, up to testing last two remaining big groups, finish (n-1) inferior detection altogether, if the withstand voltage properties between each big group is all qualified, what will do below then is: detect each big group of internal core to withstand voltage properties whether reach quality standards; 3. detect each big group of internal core between the test procedure of withstand voltage properties be: to forming one n the group that core is right arranged from each core of core centering arbitrary extracting of big group respectively, be connected to the positive terminal of withstand voltage instrument, all the other (m-1) n core done voltage-withstand test to being connected to the negative pole end of withstand voltage instrument; If qualified then; 4. all the other (m-1) n core centering from each big group respectively again, each extracts a core to forming a core to group, be connected to withstand voltage instrument positive terminal, all the other (m-2) n core is right, receive withstand voltage instrument negative pole end and do voltage-withstand test, if qualifiedly down carry out again, up to finishing latter two core to the voltage-withstand test between group.
More than four big testing procedures, it is right to remove underproof line, is exactly that the qualified line of this cable is right, that is to say that a cable is qualified, must guarantee that above four steps are qualified.
For a cable product, to do (m+n) inferior detection at most, could check its withstand voltage properties whether qualified.This method is applicable to that cable core is effective to the sizable situation of number greater than 6 situation, particularly core to quantity.
The advantage of this method is: compare with classic method, for having core to the sizable cable of quantity, use this method, it is little to have the test job amount, and detection time is short, alleviates outstanding advantages such as tester's labour intensity and raising testing efficient greatly.
