ABB PCS6000 DC Busbar Discharge Switch Assembly

Core Performance & Industrial Application

The ABB PCS6000 DC Busbar & Discharge Switch Assembly is the high voltage DC link component of the PCS6000 medium voltage converter.

It connects the rectifier and inverter power stacks, transmits stable DC power inside the converter.

The built-in discharge switch is used for safe manual discharging of DC bus capacitors after shutdown, to avoid residual high voltage risks during maintenance.

It adopts insulated copper busbar design with high voltage isolation structure, matched with capacitor bank for DC voltage stabilization.

It is equipped with voltage monitoring points to feed back DC bus voltage signal to the master control system.

It is an essential safety and power transmission part for the PCS6000 wind power converter, widely used in wind farm maintenance.
