Device and method for testing current-carrying capacity of copper bar

Abstract

The invention discloses a device and a method for testing the current-carrying capacity of a copper bar, belongs to the technical field of the current-carrying capacity of the copper bar, and aims to solve the problem that the re-measurement of the sectional dimension of the copper bar is relatively tedious due to a complicated use environment, damaged surface of the copper bar, reduced sectional area of a damaged part and deviation of a current-carrying capacity value test in the actual use process. According to the invention, the distance between the two groups of opposite measuring probes is measured through laser displacement sensors of the two groups of opposite measuring probes, numerical values measured by a plurality of groups of opposite measuring probes of the bearing plate and the hanging test plate are the thickness of the copper bar, and numerical values measured by a plurality of groups of opposite measuring probes of the connecting side long plate are the width of the copper bar; preliminary buffering is conducted through a second reset spring, an adjusting straight rod drives a jacking ball to extrude a supporting column block, a traction supporting arm rod is pulled upwards through a connecting spring, and then the supporting column block conducts secondary buffering on the jacking ball.

Description

technical field [0001] The invention relates to the technical field of carrying capacity of copper bars, in particular to a testing device and method for carrying capacity of copper bars. Background technique [0002] Copper bars are suitable for electrical engineering such as high and low voltage electrical appliances, switch contacts, power distribution equipment, and bus ducts. They are also widely used in ultra-high current electrolytic smelting projects such as metal smelting, electrochemical plating, and chemical caustic soda. Copper bus bars are one of the copper processing materials. The main varieties, copper busbar has high mechanical properties, good electrical and thermal conductivity, excellent corrosion resistance, electroplating and brazing properties, beautiful and beautiful metallic luster and good forming and processing performance, so it is used to make Various power transmission and transformation, electrical equipment, etc. have been widely used in the f...

Problems solved by technology

[0005] The object of the present invention is to provide a test device and method for the carrying capacity of copper bars, which solves the problem that the carrying capacity of copper bars in the background technology is mainly determined by three factors: material, cross-sectional area and laying conditions. The current carrying capacity of the copper bar, but in the actual use process, due to the complex use environment, the surface of the copper bar is damaged, and the cross-sectional area of ​​the damaged part is reduced, and the value of the current carrying capacity calculated by ordinary calculation is larger than the actual value of the current carrying capacity , there is a deviation in the numerical test of the ampacity, and it is cumbersome to re-measure the cross-sectional size of the copper bar, and it is not easy to test whether the numerical value of the ampacity of the copper bar meets the standard.
