12 Standards Standards, specifications, guidelines Standards The switchgear complies with the standards and specifications listed below: VDE 0670, Part 1000 VDE 0670, Part 6 VDE 0670, Part 101 et seq. VDE 0670, Part 2 IEC IEC IEC IEC In accdance with the obligaty harmonization in the European Community, the national standards of the member countries confm to IEC Type of service location switchgear can be used as an indo installation in accdance with VDE 0101: Outside closed electrical operating areas in locations not accessible to the general public. Tools are required to remove switchgear enclosures. In closed electrical operating areas. A closed electrical operating area is a room area which is used solely f the operation of electrical installations. This type of area is locked at all times and accessible only to authized trained personnel and other skilled staff. Untrained unskilled persons must be accompanied by authized personnel. Internal arc test, resistance to internal arcs Internal arc test Tests have been carried out with switchgear, in der to verify its behaviour under conditions of internal arcing. The resistance to internal arcing complies with the requirements of VDE 0670, Part 6, Appendix AA IEC , Appendix AA Resistance to internal arcs The possibility of faults in the fixed-mounted circuit-breaker switchgear is much less than in previous types, due to the single-pole enclosure of external components and the SF 6 insulation of the switchgear: All external fault-causing facts have been eliminated, such as: Pollution deposits Moisture Small animals and feign bodies Maloperations are prevented by the clear, logical layout of the operating elements The three-position switch and the vacuum circuitbreaker provide sht-circuitproof earthing of the feeder Should arcing occur in spite of this, the pressure is relieved towards the rear into a duct. In the improbable event of a fault inside the module container, the SF 6 insulation restricts the arc energy to only about 1 / 3 of that f air. The pressurerelief facility in the rear panel of the module container is designed to operate in an overpressure range of 2 to 3.5 bar. The gases are discharged towards the rear into a duct. The pressure-relief duct diverts the gases upwards. Protection against electric shock, the ingress of water and solid feign bodies The fixed-mounted circuit-breaker switchgear is fully enclosed and entirely unaffected by climatic influences. All medium-voltage switching devices are enclosed in stainless steel containers, which are welded gas-tight and filled with SF 6 gas. Live parts outside the switchgear container are single-pole insulated and screened. There are no points at which leakage currents of highvoltage potential are able to flow off to earth. All essential components of the operating mechanism are made of non-croding materials. Climate and ambient conditions The fixed-mounted circuit-breaker switchgear offers the following degrees of protection: IP3XD f external enclosure IP65 f parts under high voltage in accdance with: DIN VDE 0670, Part 6 IEC with IEC Siemens HA
