In the event that the fuse tripping fails, e.g. if the fuse has been inserted increctly, the fuse box is protected by thermal protection. The overpressure generated by overheating trips the switch via the diaphragm in the cover of the fuse box and via an articulation. This breaks the current befe the fuse box incurs irreparable damage. The above thermal protection wks independently of thetypeanddesignofthe HV HRC fuse used. Like the fuse itself, it is maintenancefree and independent of any outside climatic effects. Furtherme, the Siemens HV HRC fuses release the striker pin independently of the temperature and trip the three-position switch-disconnect as early as in the fuse overload range. Impermissibleheatingofthefuse box can be avoided in this way.

38 R-HA5-a eps R-HA5-05 eps Fixed-Mounted Circuit-Breaker Switchgear Type NXPLUS C, up to kv, Gas-Insulated Components Indicating and measuring equipment Ready-f-service indicat Features Self-moniting; easy to read Independent of temperature and pressure variations Independent of site altitude Only responds to changes in gas density Option: Alarm switch NO + NC f remote electrical indication Gas moniting Low-voltage compartment 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 armature through the non-magnetizable stainless-steel switchgear vessel. This armature moves the ready-f-service indicat of the switchgear. While changes in the gas density during the loss of gas, which are decisive f the insulating capacity, are displayed, temperature-dependent 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.
