ABB PCS6000 SYSTEM DRIVES

Security information

Safety standards and labels: Following ANSI, ISO, EN and other standards, the equipment is labeled with safety labels such as danger, warning, and caution to alert potential risks, such as the impact of high voltage, high temperature, and magnetic fields on pacemakers. The label instructions must be strictly followed.

Safe operating procedures

Seven step safety guidelines: including risk assessment, power-off locking, voltage detection, grounding short circuit, protection of adjacent live parts, etc., to ensure operational safety.

Main circuit breaker (MCB) requirements: The MCB must be directly controlled by a frequency converter, and the breaking time must comply with specifications (protection trip ≤ 75ms, safety trip ≤ 500ms), and equipped with independent trip coils or undervoltage coils.

Residual risks and maintenance: There are residual risks such as electromagnetic interference, accidental movement, and contact voltage, and it is necessary to regularly check the MCB trip circuit. During maintenance, ensure that the power is turned off and personal protective equipment is used.

product description

Application and Configuration: Suitable for large wind turbines and tidal applications, with two configurations: 1CL (single conversion line) and 2CL (dual conversion line, supporting restricted mode), supporting back-to-back, face-to-face, and series layouts.

Modular components

Power Unit (POU): consisting of three 3-level NPC phase bridge arms and IGCT, controlled by the main circuit interface board.

DC Link Unit (DLU): Integrated Neutral Connection Module (NCM), Voltage Limiting Module (VLM), dv/dt Filtering Module (VFM), Grounding Isolator, and Generator Isolation Switch Module (GDM), etc.

Grid Circuit Breaker Unit (GBU): includes a circuit breaker and a three position switch, used for grid side connection and grounding.

Other units include Water Cooling Unit (WCU), Filter Unit (FIU), Braking Resistance Unit (BRU), and Converter Control Unit (CCU), which are responsible for heat dissipation, harmonic filtering, energy dissipation, and system control, respectively.

Cabinet design: Using modular galvanized steel frame, protection level IP54, electromagnetic compatibility (EMC) achieved through sealed design, standard color RAL 7035, supporting crane or forklift handling.

Transportation, storage, and disposal

Transportation requirements

Packaging method: Wooden pallets and polyethylene film are used for land transportation, while wooden boxes and aluminum foil moisture-proof film are used for sea transportation. Symbols such as "fragile" and "keep dry" should be marked.

Loading and unloading precautions: Use a crane or forklift, keep the equipment upright, avoid tilting at an angle exceeding 30 °, and do not stand on top of the cabinet.

Storage conditions: The original packaging can be stored for 1 year in a dry, dust-proof, and corrosion-resistant environment, following the IEC 60721-3-1 standard. Spare parts need to be stored anti-static.

Disposal requirements: Components such as batteries, capacitors, and circuit boards must be disposed of in accordance with local regulations to avoid environmental pollution.

installation guide

Mechanical installation: It needs to be carried out in a dust-free environment. The cabinet is fixed to the floor with M16 bolts. After installation, check for paint damage and repair to ensure that there are no foreign objects left.

electrical installation

EMC zoning: divided into five areas: power grid, transformer, power section, control cabinet, and generator. Cables need to be isolated and laid according to categories (Class 1-4), with spacing in accordance with IEC 61000-5-2.

Cable requirements: Power cables must be shielded and meet the IEC 60228 standard; The distance between the control cable and the power cable should be ≥ 30cm, and they should be laid vertically when crossing.

Grounding system: The protective grounding (PE) is separated from the functional grounding (FE), and the cross-sectional area of the grounding conductor is ≥ 95mm ² to ensure safe discharge of fault current.

Debugging and operation

Debugging preparation: It needs to be carried out by ABB certified personnel to inspect mechanical installation, electrical connections, grounding, cooling systems, etc., complete insulation testing and parameter settings, and sign the debugging report.

Operation interface: Local control devices include emergency stop buttons, key switches, status indicator lights, and debugging ports, supporting remote control through fieldbus.

Startup process: The anti dew startup sequence (heating control unit and water circulation) needs to be completed, and the auxiliary power supply, cooling system, door lock status, and circuit breaker position need to be checked to ensure that there are no fault alarms.

Emergency operation: Pressing the emergency stop button will disconnect the main power supply, discharge the DC link, and manually reset and clear the fault before restarting.

Maintenance and troubleshooting

Preventive maintenance: including visual inspection (dust, signs of overheating), cleaning, performance testing, and component replacement, following the PCS6000 Preventive Maintenance Plan (3BHS600000 E88), and recording maintenance logs.
