Description
Technical field
The present invention relates to wire and cable production fields, and in particular to a kind of process control resistance measurement method.
Background technique
With the development of modern science and technology, industrial automatization is higher and higher, the various industries that are ensured of of quality are rely life
The basis deposited and developed, wires and cables industry does not arrange outside yet, and 20 DEG C of conductor DC resistance is that wire and cable is qualified or not
Basis, so, in electric wire line cable industry, guarantee that 20 DEG C of wire and cable of conductor DC resistance is the most important thing.
The measurement method of 20 DEG C of wire and cable traditional of conductor DC resistance is: taking sample first, in conductor production；
Secondly, sample is sent to laboratory (or specified sensing chamber) to detect, after measurement is qualified, can continue to be produced.
Such detection method has the shortcomings that certain: the first, detect process need the regular hour, be not detected result it
Before, it cannot continue to produce, so wasting the time to a certain extent；The second, this detection method is sampling observation, cannot be existed well
The control of overall process is not carried out to 20 DEG C of conductor DC resistance in production process；Third, when being inspected by random samples again, if hair
Existing unqualified, material can also waste.
Summary of the invention
The purpose of the present invention is to provide a kind of process control resistance measurement methods, to solve electric wire in the prior art
Inspect the problem of resistance leads to time waste and real-time monitoring in cable conductor production process by random samples.
The present invention provides a kind of process control resistance measurement methods, include the following steps:
(1) resistance measuring instrument is mounted at the production equipment of production electric wire and cable conductor；
(2) resistance measuring instrument is powered, and according to product demand, adjusts production equipment range；
(3) production equipment starts to produce electric wire and cable conductor, and the electric wire and cable conductor produced passes through resistance measuring instrument；
(4) resistance measuring instrument measures the resistance value of the electric wire and cable conductor under actual temperature；
(5) resistance value measured under actual temperature is converted to 20 DEG C of resistance value, and resistance value real-time display is existed
On the station of production equipment；
(6) 20 DEG C of resistance value and standard electric resistance value are compared, when qualified, enters step (8), enters when unqualified
Step (7)；
(7) manufacturing parameter is adjusted, and repeats step (3)-(6)；
(8) continue to produce.
Further, the resistance measuring instrument measures the resistance value of the electric wire and cable conductor under actual temperature using both arms
Electric bridge measuring resistance principle.
Further, the resistance value that the resistance value that will be measured under actual temperature is converted into 20 DEG C passes through temperature signal
Converter or the method for temperature-compensating.
