In addition, the automatic testing device and methodcan be expanded to be used for other wiring test projects needing to be ascended, and high practicality is achieved.

Description

technical field [0001] The invention relates to the field of high-voltage electrical test devices, in particular to an automatic test device and a test method for mechanical characteristics and loop resistance of switchgear. Background technique [0002] With the development of society, the electricity consumption of industries and residents has increased, and people's dependence on power supply and reliability requirements have become higher and higher, and the electricity load has continued to deepen. As the most important control and protection equipment in power transmission, transmission grade switchgear has also been developed rapidly. [0003] Due to the high voltage level of transmission level switchgear, its weight is heavy, its volume and height are large, and because of its poor stability, it is not easy to transport, so when it is tested for mechanical characteristics and circuit resistance, the test product generally remains assembled. The position does not mov...

AI Technical Summary

Problems solved by technology

Therefore, the existing mechanical characteristics of the switchgear and the circuit resistance test operation method have the following deficiencies: ①The mechanical characteristics of the switchgear and the loop resistance test need to be connected and disconnected many times, which has potential safety hazards for personnel to ascend the height; ②Connect and disconnect the wires The workload is heavy, and there are manual wiring omissions. When the constant current source is supplied, the connecting cables have large specifications and high quality. It is also necessary to ensure that the connecting cables have good contact resistance, which is time-consuming and laborious, and the work efficiency is low.
