6 Requirements Features Safety Environmental independence Hermetically tight, welded switchgear vessels made of stainless steel as well as single-pole solid insulation make the parts of the primary circuit under high voltage of NXPLUS switchgear Insensitive to certain aggressive ambient conditions, such as: Air humidity Dust Condensation Tight to ingress of feign objects, such as: Dust Pollution Small animals Humidity Independent of the site altitude. Compact design Thanks to the use of SF 6 insulation, compact dimensions are possible up to 40.5 kv. Thus: Existing switchgear rooms and substation rooms can be used effectively New constructions cost little Costly city-area space is saved. Maintenance-free design Switchgear vessels designed as sealed pressure systems, maintenance-free switching devices and enclosed cable plugs ensure: Maximum supply reliability Personnel safety Sealed-f-life design accding to (sealed pressure system) Installation, operation, extension and replacement without SF 6 gas wk Reduced operating costs Cost-efficient investment No maintenance cycles. Innovation The use of digital secondary systems and combined protection and control devices ensures: Clear integration in process control systems Flexible and highly simplified adaptation to new system conditions and thus to cost-efficient operation. Service life Under nmal operating conditions, the expected service life of gas-insulated switchgear NXPLUS is at least 35 years, probably 40 to 50 years, taking the tightness of the hermetically welded switchgear vessel into account.

53 Components Indicating and measuring equipment Ready-f-service indicat Self-moniting; easy to read Independent of temperature and pressure variations Independent of the site altitude Only responds to changes in gas density Signaling switch, 1 changeover contact, f remote electrical indication. Mode of operation F the ready-f-service indicat, a gas-tight measurement box is installed inside the switchgear vessel. A coupling magnet, which is fitted to the bottom end of the measurement box, transmits its position to an outside signaling switch through the non-magnetizable switchgear vessel. Then, the armature activates the proximity switch. While changes in the gas density during the loss of gas, which are decisive f the dielectric strength, are displayed, temperaturedependent changes in the gas pressure are not. The gas in the measurement box has the same temperature as that in the switchgear. The temperature effect is compensated via the same pressure change in both gas volumes. Indication Signaling switches -S41..S44 are wired to the binary input of the bay controller Indication as panel group signal at the bay controller Substation group signal is transferred to the telecontrol system. NXDENS (option) Signaling switches -S41..S44 are wired to the NXDENS indicat Indication as panel status message on NXDENS indicat Green status LED Panel is ready f service Red status LED Panel is not ready f service If the status LED lights up red, missing service readiness can be spatially assigned to the individual module vessels through the LEDs The spatially crect assignment is suppted by suitable pictograms at the switchgear front Signaling relays are available f signaling and moniting of each module vessel (telecontrol system) Life signaling relay monits proper operation of NXDENS (telecontrol system) The Test key is used f checking proper operation of the red LED The crank generat (below the status LEDs) allows f sht-time checking of service readiness, even if the auxiliary voltage supply is missing.
