Research on flexible intelligent testing technology and engineering application of substation switch

As the core data exchange equipment of substation, the stability and reliability of the switch is very important for the efficient operation of substation. However, due to the unique structure of the switch and strict industry test standards, the manual test method is widely used in the whole machine test at present, which has the disadvantages of labor-intensive and low automation level. This paper has carried out in-depth research on these technical problems that perplex the automatic test of switches. Firstly, the image recognition technology is introduced in the automatic recognition of LED panel lights of the switch, and successfully realize the automatic recognition of LED lights. Secondly, when solving the problem of intelligent judgment and handling of different types of switches, we introduce the handling robot to solve the problem of unmanned handling, and develop various types of flexible testing accessorial tool to adapt to different types of switches. Finally, in the aspect of switch flow detection, we propose an S-type flow test technology, and combine the automatic chemical equipment and flow tester to achieve a fast and effective flow pressure test. Based on the above research, a set of flexible intelligent test system for switches is developed. At present, the system has been put into use in an intelligent manufacturing demonstration workshop in Nanjing, Jiangsu Province, which effectively improves the testing efficiency of the switch, and has a good demonstration significance in the industry.
