AI Technical Summary
Existing busbar trunking has high resistance when transmitting high-frequency, high-current signals, resulting in significant power loss. Furthermore, the fixed heat dissipation location prevents heat from being dissipated quickly, affecting operational stability and safety.
The busbars are made of high-purity electrolytic copper and silver-plated, combined with silver-plated springs to reduce contact resistance. A temperature sensor and PLC logic controller control the movement of the impeller and air inlet hopper driven by a servo motor to achieve an adjustable heat dissipation system, which dissipates heat through corrugated expansion tubes and air pipes.
It significantly reduces resistance loss, ensures efficient power transmission, and evenly dissipates heat through movable heat dissipation locations, avoiding localized overheating and ensuring the operational stability and safety of the busbar.
