Problems solved by technology
However, because the voltage and speed regulating device often works in a high temperature environment, the high temperature will cause the electronic drift phenomenon of the thyristor, which will have a great impact on the performance of the electronic components. Therefore, the relevant parameters in the high temperature environment cannot be detected in the experiment at room temperature. , the reliability test cannot be carried out, so the factory quality control cannot be guaranteed
[0004] At the same time, the above method is manual operation, the workload is complicated before and during the detection process, and a large amount of detection data is required
Due to the limitation of one's own energy, it is easy to miss relevant parameters, and the voltage and speed regulating device will generate extremely high voltage and current during the test process. Manual detection will easily cause great harm to personal safety.

Description
technical field [0001] The invention relates to an experimental detection system for a voltage and speed regulating device for a crane, in particular to a life detection system for a thyristor in a voltage and speed regulating device for a crane in a high-temperature environment based on automatic control. Background technique [0002] The pressure and speed regulating device for cranes is the core control unit of the crane, especially in the lifting industry in harsh environments such as metallurgy, ports, and mines. Since the core component of the voltage regulating and speed regulating device is the thyristor, the physical characteristics of the thyristor itself make it vulnerable to damage during production and installation, which in turn reduces the life of the thyristor or even damages it. Thereby affecting the operation and even production safety of the whole crane. For this reason, it is necessary to conduct reliability testing experiments on the pressure and speed ...
