ABB GRID BREAKER UNIT GBU72 3BHE055094R0002 / 3BHE031197R0001 / 3BHB030310R0001

Filter unit (FIU)

The FIU is an RLC filter tuned to fulfill the harmonic limits defined by the relevant grid standards.

Braking resistor unit (BRU)

The braking resistor is able to dissipate the full generator power (plus temporary overproduction and DC-Link discharge) in any operating condition for a certain time. The power switching to the braking resistor is done by a Voltage Limiting Module (VLM). The braking resistor is modular for different converter power ranges. The BRU can be placed somewhere close to the converter. A roof installation is possible. The maximum cable length between converter and BRU is 10 m. The monitoring/control of the BRU resistor temperature is done with a temperature model on the main circuit interface. The BRU varies depending on converter size and application.

BRU51 2 × 7.5MJ 2x1.8 Ohm / stand-alone / cable clamp DI 28 mm

BRU52 2 × 7.5MJ 2x1.8 Ohm / roof mounting / cable clamp DI 40 mm

BRU72 2 × 15MJ 2x1.5 Ohm / stand-alone / cable clamp DI 28 mm

Converter control unit (CCU)

The CCU incorporates the hardware for the control, monitoring and protection functions of the converter as well as the communication interfaces to the remote control hardware.

Cabinet design

The cabinet has been designed using the modular cabinet system of ABB and fulls the requirements of international standards. The design consists of a skeletal frame made of galvanized steel where the outer panels made of 1.5 mm thick painted galvanized steel are bolted to. Corrosion resistant materials are used to ensure durability of the cabinets.

Electromagnetic compatibility (EMC)

Electromagnetic compatibility (EMC) has been achieved by applying an EMC sealing around the doors and on the rear and side panels. The inside panels of the compartments are not painted, because paint tends to reduce the effectiveness of metallic bonding, which is paramount to successful EMC. The joining surfaces of two transport units are equipped with EMC sealing strips. The cabinet doors and the internal cable ducts are also equipped with EMC sealing.

Degree of protection The standard cabinets are rated for IP 54. The sound pressure level is < 75 dB (A). Painting The standard color for the cabinets is RAL 7035 (light gray), which is applied as a powder coat paint.

Transportation

Small converters are shipped as one unit. Larger converters are shipped in separate transport units. All transport units are fitted with lifting lugs for a crane that must be used to position the units.

Safety labels

Safety labels are attached to the converter doors to alert personnel of potential hazards when working on the converter.

The standard language of the labels is English; however, other languages can be ordered. The label design is based on the relevant ANSI and ISO standards (see section 2.3, Product safety labels, page 20).
