This ensures that the input and output points of different modules are accurately corresponding during the reconstruction and replacement process, reduces the error rate of wiring reconstruction, improves the work efficiency of the reconstruction, and improves the operating stability of the unit after the reconstruction by increasing the lightning protection function of the line.

Description

Technical Field

[0001] The present invention relates to the field of technical upgrading and transformation of wind turbine generator sets, and specifically, to a method for manufacturing and wiring a circuit board for module replacement and transformation, and more specifically, to a method for manufacturing and wiring a special circuit board for replacement and transformation between different modules under the background of aging and shutdown of wind turbine generator set modules, so as to improve the work efficiency of technical transformation of wind turbine generator sets and reduce the error rate of technical transformation, especially wiring transformation. Background Art

[0002] Limited by the technology at the time, the analog and digital modules used in early wind turbines were relatively old models, and their technical performance could no longer meet the growing demand for technological upgrades of wind turbines. This caused problems for the stable operation of wind turbines under the ever-changing power grid technology requirements. In addition, some modules have been discontinued by the manufacturers, and if the modules are damaged, there will be no spare parts to replace them. In serious cases, the entire wind turbine may be unable to continue operating, causing economic losses.

[0003] In order to solve this problem, wind power manufacturers have proposed an upgrade and transformation plan to replace the old analog and digital modules used in the earlier units with new modules, and many wind farms have adopted it. During the upgrade and transformation process, the wiring of the original analog and digital modules needs to be transferred to the new analog and digital modules. Most of the existing transformations are done by directly changing the wiring, but since there are many wirings on each module, it is easy to make mistakes; and because the size and wiring position of the new and old analog and digital modules will change, the required length of many connected cables will change before and after the transformation. For cables that need to be longer, they need to be rewired and rerouted and the original cables need to be removed from the cable duct. In this way, the entire replacement and transformation takes a long time, the workload is large and cumbersome. In addition, the signal input circuit of the old analog and digital modules is easily damaged by lightning, which increases the failure rate of the stable operation of the wind turbine and increases the operation and maintenance costs.

[0004] In order to improve work efficiency, reduce wiring error rate, enhance the lightning protection function of the signal circuit, and improve the operating stability of the unit after transformation, it is necessary to design and manufacture a transfer circuit board with lightning protection function for the technical upgrade and transformation of the above-mentioned analog and digital modules. It is very feasible and necessary to realize the rapid transfer of signal lines during transformation. Summary of the invention
