Technical Field
The utility model relates to an electric power tech field specifically is a cable conductor current-carrying capacity testing arrangement.
Background
The current-carrying capacity data and the calculation method of the conductor can be found in various data, but the cross section, the material, the specification and the process of the cable conductor and the structure of the finished cable can cause certain differences of the current-carrying capacity of the conductor, and the actual current-carrying capacity of the cable conductor cannot be measured through an actual test.
At present, the method for verifying the current-carrying capacity of the electric wire mainly comprises the following steps: calculating and laboratory verification, wherein the basis of calculation is JB/T10181 mechanical industry standard; the wire verification method is characterized in that verification is performed after installation in a use environment according to the use environment of the wire during laboratory verification. The current-carrying capacity calculation is carried out according to the standard, wherein 107 main key parameters are involved, such as material parameters and environmental parameters, so that the current-carrying capacity of a corresponding product needs to be recalculated when any one of the material parameters is changed or the environmental parameters are changed. Meanwhile, because the parameters are too many, the accumulated error can seriously affect the final calculated value, so that the calculation error is easy to generate. When laboratory verification is carried out, infrastructure consistent with the using environment of a product, different products, different using environments and different specifications need to be built correspondingly, so that the problems that the verification period is long, verification equipment needed by verification is more, and the verification effect is not intuitive exist.
