Product Details
The crow-bar protects the intermediate DC-circuit. The activation of the crow-bar during normal operating conditions is not necessary and unusual. Nevertheless it could be that the crow-bar has been switched on. In that case it is justified due to a misdemeanor of other components. The components must be checked then.
To protect the Crow-Bar components (dI/dt choke, thyristors) against undesirably current flow and with it high temperatures the components are fitted with thermal switches with a threshold > 80°C and a thermal protection relay (F40) which isolates the primary circuit from the supervision circuit. The relay is switched into the “Ringline shut down” circuit which switched off the system immediately in case of failure. The fault “M24: Ringline shut down” will be displayed and recorded in the Customer Tool.
The current flow through the system and therewith through the components will be disconnected immediately. It is impossible to reset the Relay (F40) remotely. The service must reset the relay manually after they have checked the components. If necessary change the components. The dI/dt choke and thyristors are designed for a maximum temperature of 125°C. To insure a safe operating of the components the threshold of the thermal switches are selected to 80°C.
