Problems solved by technology

[0006] 1) Timeliness issue
[0007] ①The effect of tinning surface treatment is not stable, and it is often necessary to repeat tinning or use fitter technology for leveling treatment, which is inefficient (taking a set of three copper bar joints as an example, it takes about 35 minutes to 50 minutes; ②Many personnel are redundant (three operators, one full-time guardian), it will cause manpower tension
[0008] 2) Security issues
[0009] ①Splash of high-temperature tin water during operation can easily burn the human body; ②Oxyacetylene flame melts tin to form a local high temperature, and the high-temperature movement of the open flame can easily burn the human body
The safety problem of using traditional methods to deal with the tin-coated surface is prominent

Description

technical field [0001] The invention relates to the field of electrical processing equipment, in particular to a tinning device for a gear lifting type copper bar bus joint. Background technique [0002] During the maintenance, renovation and installation of power substation professional equipment, it is often necessary to make conductive copper bar joints. In this work, there is a very critical process that needs to be completed: copper busbar joint tinning. The significance of tin enamel lies in that the tin enamel of the copper bar connector can effectively prevent the oxidation and electrochemical corrosion of the overlapping surface of the copper bus bar, and avoid the increase of contact resistance. The requirements for lap joints of copper busbars are clearly stipulated in the national standard of the People's Republic of China "Code for Construction and Acceptance of Busbar Devices in Electrical Installation Engineering" (GB / 50149-2010), Section 3.1.8 of GB / 50149-...
