AI Technical Summary
When the gas-insulated switchgear is in use, the heat generated by the contact resistance of the contacts cannot be effectively dissipated, causing the temperature inside the sealed cabinet to rise. Existing technologies have poor heat dissipation performance.
The system uses an insulated heat pipe evaporation section to absorb heat and vaporize by contacting a stationary contact. Heat is conducted and dissipated through a flexible tube, an insulated tube assembly, and a heat sink. It is also equipped with a drive unit to move the frame for cleaning and air blowing. Combined with a flywheel heat dissipation assembly, it generates airflow for air cooling.
It effectively reduces the temperature inside the gas chamber, improves heat dissipation efficiency, and prevents dust accumulation through cleaning components and airflow circulation, ensuring continuous and efficient heat dissipation.
