The H.VIR* is a patented window enabling a safe visual and IR ( band 2 and 3 ) non destructive inspection of internal areas of protected closed cells. It is specially adapted to the inspection of major electrical components. Permanently fitted on switchboards, transformer panels, cell doors, it constantly permits an IR surveying without downtime.

Advantages:

Saving money
The H.VIR window enables preventive inspections of critical areas (Connecting bars, breakers,...) without interrupting or disturbing the process.

Safety
Without H.VIR, the IR inspection may be impossible or dangerous due to electromagnetic radiations (NFPA - 70 - E standard). In particular, it permits a safe inspection of high voltage equipment.

Approval
The H.VIR has been widely distributed all over the world since 1995 and meets all of the safety rules for explosion-proof cells. It conforms with different international standards. A lot of manufacturers now include the H.VIR in their proposed equipment.

THE WINDOW COMPRISES:

• A waterproof metallic frame ( IP67 level of the NF EN 60529 standard ) to be fitted on the equipment panel by means of 3 screws and an o-ring supplied with.
• A transparent impact resisting ( IK07 level of the NF EN 50102 standard ), external protecting shield which can be opened or closed by means of a magnetic lock.
• An optical plate transparent to UV, visible and IR radiations according to the working wavelengths. Two window types exist only differing in the window material.

APPLICATIONS

• The H.VIR window is particularly adapted to following applications:
• high voltage protection cells (connecting cable head visualization, circuit breakers, fuses and fuse-boxes);
• high-low voltage transformers: low voltage connection boxes;
• low voltage distribution (400V): main circuit breakers (distribution bar connectors, bar connectors and crimping), low voltage output, plug in racks;
• electric motors (medium and low voltage except ADF): connection boxes, DC motor commutators,
  synchronous or asynchronous motor rings;
• The standard models meet the normal use conditions of electric cells and transformers:
• temperatures from –50°C to 55°C included and differential pressures up to 1.2 bar.
• they are exclusively designed for an inside use under standard environmental conditions.
  • Generator connection sockets.
  • Motor connection sockets.
  • Connectors.
  • Closed high, medium and low voltage cells.
  • Communication switchboards.
  • General equipment for energy distribution.
  • Motor control panels.
  • Unit and components for high, medium and low voltage switch board.
  • Low, medium and high voltage driving equipment.
  • Distribution switchboards
  • Connector boxes for Power transformer boxes.
  • Bar sets.
