AI Technical Summary
The existing 10kV high-voltage fixed metal-enclosed switch cabinet lacks independent secondary cable channels, which leads to weak current signals such as secondary cables being easily disturbed by high-voltage and strong electrical signals, and the protection of weak current cables is insufficient.
A secondary cable channel of a high-voltage fixed cabinet is designed, including a coplanar connection upper and lower guardrail plates, with bent edges on the left and right sides to form a sealed channel, and abutting the bent edges through the Z-shaped first and second channel support strips to form a cable channel.
Through independent secondary cable channels, the secondary cable and the 10kV switching chamber cable chamber are effectively isolated, avoiding interference from weak current signals and improving the protection effect of weak current cables.
