5) Control cabinet door: danger of slight injuries, eg, foot crushing as the door of the control cabinet is not fixed to the cabinet when the locks are open.– Support the door with your hand when opening the locks.

– Weight per door: approximately < 20 kg. 6) Generator disconnector: risk of excessive arcing due to undetected arc.

– Risk of injuries from particles, contamination, electric shock, hearing damage, burns, explosion due to hardware failure, operation beyond specified limits, unauthorized access– No access to converter room or platform is allowed when the turbine is idling with open generator disconnectors or a 2CL converter is running in constricted operation 

– Turbine idling speed shall be limited to a maximum of 30% of rated speed

– 2CL converter must not be operated in constricted mode, except in case of converter defect that requires disconnecting the defective converter train

– Operation time in constricted mode and idling with open disconnector must be reduced as far as possible

Important note- main circuit breaker

The main circuit breaker (MCB) is a major protection device of the converter. If a serious fault occurs in the converter, the MCB must disconnect the main power supply to the converter immediately. The main power supply must be disconnected without delay on an open or trip command from the converter to prevent hazard to the personnel and further damage to the equipment. The MCB is located on the primary side of the converter transformer.

Safety and protection requirements

The system integrator must ensure that the following minimum safety and protection requirements for the converter are met.

– ISO13849-1

– IEC60204-1

Safety and protection requirements for the MCB

The following safety requirements are also in the MCB specifications for the converter:

– MCB open and/or trip command:  must be wired directly from the converter to the MCB. If you want to wire the command through a PLC or DCS system, the system must be certified to meet SIL 3 requirements and to fulfill the maximum MCB opening timing requirements. The converter must also be able to open the MCB at any time. It is not permitted to interrupt the open and/or trip command, eg, with a local-remote switch in the MCB.– Closing control of the MCB:  when the MCB is in service position, the converter must have exclusive control over closing the MCB, ie, local closing of the MCB is not permitted.

– MCB maximum opening time:  cannot exceed the maximum time that is defined in the product or project-specific MCB specifications. Typical maximum values for the converter are defined as follows:– Maximum protection trip time:  75 ms The maximum protection trip time is the maximum allowed breaking time (open and arcing) of the breaking device after the open command has been initiated to prevent further damage to the converter.

– Maximum safety trip time:  500 ms The maximum safety trip time is the maximum allowed time to ensure safe disconnection of the main power supply to prevent any hazard to personnel.

Maintenance recommendation

The MCB trip circuits should be checked annually.
