AI Technical Summary

⚠Technical Problem

The existing high-voltage switchgear has few improvements in connection structure, the strength of contact box has not been improved, and it is easily damaged under high-voltage impact. Inaccurate temperature sensor position setting leads to inaccurate and untimely temperature measurement.

⚗Method used

It adopts a modular structural design, including a spherical contact box, a non-flat partition, a pressure relief component, and multi-point temperature monitoring. Combined with a temperature early warning device with a reliability coefficient, the positions of the partition and temperature sensor are optimized to improve shock resistance and temperature measurement accuracy.

🎯Benefits of technology

It improves the impact resistance of high-voltage switchgear and the accuracy of temperature measurement, reduces the probability of component damage, provides timely temperature warnings, and enhances the accuracy and safety of operation.
