AI Technical Summary

Technical Problem

Traditional new energy transformer low-voltage switchgear is cramped due to the excessive concentration of components, making installation and disassembly complicated, maintenance inconvenient, and posing a risk of electric shock.

Method used

The power distribution components are moved to the maintenance compartment outside the low-voltage cabinet. The low-voltage incoming and outgoing copper busbars of the frame circuit breaker are designed with a modular structure, and a maintenance compartment is set up inside the cabinet to isolate exposed live areas and provide ample maintenance space.

Benefits of technology

This design achieves a compact layout within the low-voltage cabinet, improving operational safety and ease of use, reducing the risk of equipment damage, and simplifying the maintenance process.
