Water-cooled High voltage inverter Product Features: 1. Power unit cabinet
Main components: power unit (including HV-IGBT), current sensor, water cooling pipeline.
Main functions: By controlling the HV-IGBT, the frequency conversion speed regulation function and the unit automatic bypass function are realized; based on the carrier phase shifting technology, the power units output perfect sine waves in series; the pipeline has a built-in cooling medium, which is driven by the circulating pump. The heat inside the unit is transported to the radiator.
2. Water cooler
Main functions: The main circulation pump promotes the reciprocating circulation of the cooling medium between the air radiator and the power device to achieve the effect of heat dissipation; the circulation pipeline is equipped with a high-level water tank as a voltage stabilization buffer device, which maintains a constant pressure for the system and can absorb the cooling medium in the system. The volume change ensures the normal operation of the entire system.
Main components: main circulating pump, filter, circulating pipeline, air radiator.
3. Concept Drive Circuit and Busbar Design
Higher reliability, higher power density, and lower voltage spikes.
4. Typical load
Blast furnace blower, oxygen compressor, boiler induced draft fan, sintering main exhaust fan, fan, water pump and other loads.
