Description

Product Overview

5SHX2645L0004 (alias order code 3BHL000389P0104) is ABB reverse‑conducting press‑pack IGCT power semiconductor device. It integrates GCT chip and free‑wheeling diode inside one press‑pack housing, used as core power switching component inside ABB medium‑voltage converters such as ACS6000, PCS6000 series. It undertakes rectifier and inverter power conversion for multi‑megawatt medium‑voltage motor drives.

High‑power medium‑voltage converters require high blocking voltage, large turn‑off current and low conduction loss. Conventional IGBT modules cannot satisfy MW‑class medium‑voltage application requirements. 5SHX2645L0004 uses press‑pack double‑sided heat‑dissipation structure, supports optical fiber gate triggering, and can be assembled with external gate‑drive unit and snubber circuits. It can be series‑parallel expanded to realize higher‑power conversion, widely used as critical spare for metallurgy, power‑plant and renewable‑energy converter cabinets during overhaul and outage maintenance。

Key Features and Advantages

reverse‑conducting integrated design: 5SHX2645L0004 integrates IGCT and free‑wheeling diode within single press‑pack housing. It reduces quantity of discrete power devices inside power unit cabinet, lowers cabinet volume and parasitic inductance.

press‑pack pressure‑contact packaging: Double‑sided heat‑dissipation supports high‑intensity water‑cooled or forced‑air cooling; good vibration resistance, suitable for heavy‑duty continuous full‑load operation.

ABB 5SHX2645L0004

optical fiber gate trigger: Gate signal transmitted by optical fiber, fully galvanically isolated from high‑power main circuit, strongly resists EMI interference inside medium‑voltage cabinet, avoids false triggering caused by high‑voltage surges.

low conduction loss: Advanced chip technology reduces on‑state loss, improves overall efficiency of medium‑voltage converter, lowers cooling‑system load for MW‑level equipment.

flexible expandability: Supports series‑connection for higher voltage and parallel‑connection for higher current, satisfies capacity‑demanding applications up to dozens of MVA.

strict installation requirements: Press‑pack device must be installed with specified torque; uneven pressure will cause local over‑heating and permanent chip damage. Static‑sensitive component; ESD protection must be applied during handling.

Application Fields

5SHX2645L0004 is installed inside ABB ACS6000 / PCS6000 medium‑voltage converter power cabinets.

In thermal‑power‑plant auxiliary systems, it is used for medium‑voltage frequency converters of induced‑draft fans, forced‑draft fans and circulating‑water pumps to realize energy‑saving variable‑speed regulation of high‑voltage motors.

Within metallurgical and mining industry, it serves main‑process large drives: mine hoists, rolling‑mill main drives and heavy‑duty conveyors, undertaking rectification and inverter power‑switching tasks. It is also adopted in large‑scale wind‑power full‑power converters and industrial active power‑filter equipment.

During converter‑equipment overhaul and spare‑replacement projects, it replaces aged press‑pack IGCT chips. Existing gate‑drive boards, snubber circuits and cooling system can be reused. It belongs to critical spare‑part inventory for heavy‑industry maintenance‑workshops supporting ABB medium‑voltage drive assets.

Installation and Maintenance

pre‑installation preparation: Before installing 5SHX2645L0004, fully power‑off the medium‑voltage converter and discharge DC‑bus capacitors. Wear ESD anti‑static wrist‑strap. Strictly follow torque‑specification for press‑pack installation; uneven pressure will lead to chip burnout. Inspect optical‑fiber connectors for dirt and damage. After mechanical assembly, perform power‑unit withstand‑voltage test and optical‑path trigger test before putting converter into operation.

maintenance recommendations: During unit outages, inspect cooling‑loop condition (water flow, leakage and scaling for water‑cooled version). Check optical‑fiber connector cleanliness and surface condition of press‑pack contact plane. Do not hot‑swap under high‑voltage energised cabinet state. If repeated power‑unit faults occur, verify installation torque, cooling effect and optical‑link status before replacing device. This press‑pack semiconductor chip has no field‑repairable internal parts; send defective device back to ABB‑authorized repair‑centres.

Product Warranty & Support

Each 5SHX2645L0004 passes factory power‑cycling test, optical trigger validation and voltage‑withstand inspection before shipment. Standard equivalent warranty covers manufacturing defects for 12 months from delivery date. Spare‑part sourcing, remote‑technical guidance and SAT‑support services are available for spare‑replacement, installation‑torque guidance and power‑unit commissioning. Application‑engineers offer support for press‑pack installation procedure and power‑unit fault‑diagnosis. Long‑term spare‑parts inventory mitigates obsolescence risk for installed ABB medium‑voltage converter assets.
