THE COURSE IS INTENDED FOR:

The high voltage training is intended for engineering officers responsible for standing watch in the engine room and electro-technical officers. Training consists of a theory section taught in classrooms and practical classes conducted in a specialised room, all in a safe environment.

The operational level is intended for engineering officers and electricians. During this training, students are familiarised with the basics of high voltage and the operation and maintenance of the high-voltage device.

Apart from the previously mentioned competencies, students work on safety procedures on the management level: risk assessment, issuing the work permit, issuing the licence for testing the shipboard high-voltage facility. The training is intended for senior engineering officers holding command responsibility.

The presented device is the central device for working with high voltage. The block was manufactured in cooperation with Končar and the most up-to-date shipboard equipment by Siemens, ABB and Scheinder was installed inside.

The main component of the high-voltage block is the circuit breaker section, used to cut the power supply. The other component is the busbar section, transferring the electric current necessary for supplying power. The cable section contains cables that are connected to connectors and transformers. All safety and control functions relating to high voltage are integrated into the control or monitoring section. The most important section for the personnel is the channel used to let-off unwanted pressure, electrical arches and flashes.

The equipment tests even included impact, tilting and vibration testing, which are standard tests for shipboard equipment.

The high-voltage vacuum circuit breaker, adapted to work in pairs, was made by ABB. There are strictly defined procedures that need to be observed when working with this device, ensuring a realistic simulation of working with the device.

The accompanying documentation enables fast fault-finding. It is used to repair faults and carry out device maintenance. When working with high voltage it is important to use protective devices, which will be presented at a later time.

 

ABOUT THE DEVICE:

ABOUT THE DEVICE

BVK-M-7,2(12) is a high-voltage metal-clad switchgear for indoor installation, intended for marine purposes. Unit compartments are separated by metal partitions, and the live parts are insulated by air. Switchyard is equipped with all the blockages and equipment needed to provide a high degree of safety and reliability for the staff and the installation itself. Blockages are achieved by keys, padlocks or blocked magnets.

BVK-M-7,2(12) switchgear is equipped with vacuum switches and contactors. The vacuum switches and contactors cover the entire scope of parameters, and thus have whole range of applications. ABB switching devices are notable for their exceptional electrical and mechanical characteristics, long life span without maintenance, compactness and the use of innovative construction techniques.

Air-insulated switchgear with pull-out equipment provides users with: high availability and reliability of the switchgear; complete safety of the operating crew; low maintenance; inability of incorrect operation due to the electro-mechanical blockages; quick and easy installation.

The installation and the main devices contained in the high-voltage switchgear are subject to the following standards: IEC 62271-1 for general purposes; IEC 62271-200 for switchgear; IEC 62271-102 for earthing switches; IEC 60071-2 for coordination of insulation; IEC 62271-100 for switches; IEC 60044-1 for power transformers; IEC 60044-2 for voltage transformers.

Degrees of protection of the installation are in compliance with the standard IEC 62271-200. BVK-M-7,2(12) switchgear is normally supplied with the following standard degrees of protection: IP43 for the outer case; IP2X inside the case.

Characteristics of the application of the switchgear: the highest category of loss of continuity of the switchgear (LSC2B); reliable power supply to the consumers even in difficult conditions; resistance to the spread of a possible arc fault on adjacent junction sections; safety from the wrong manipulation – mechanical and electrical blockages; resistance to shocks, vibration and tilting; improved mechanical strength – using sheet metal of greater thickness and stiffness; rationalization of the use of space on board – reducing the size of switchboard panel; launching, maintenance and replacement of equipment are carried out from the front; high voltage on board – reducing costs, energy consumption and CO2 emissions; a wide range of functional units.
