Fire: Loss prevention by infrared thermography
Infrared eye seeks potential fires in electrical
installations VDI Nachrichten, 20.4.00 - In transmission
lines, switching cabinets and other electrical systems of
many farms lurks considerable fire risk. Industrial insurers
now recommend using infrared cameras to grips with the
danger of fires in industrial rücken.Viele go to the account
of so-called "hot spots" in the field of electrical systems
and components, as this "hot spot surface with conventional
tests are not recognized in time .
Unlike in France, where one uses for the early detection of
infrared thermography. They want industry, insurers and the
Association of thermographers (Vath now) but also introduce
in Germany, taking into account the high quality standards.
Prerequisite is the use of appropriate in accordance with
infrared cameras that are used depending on loan size of the
maintenance or p service. My German industrial insurer to
reduce them in Germany, the fire cases by 30% können.Für
utilities means thermography is nothing new.
Here she is as a common measurement standard. Has for
electrical systems in the industry, the thermography is
often not proven to be the only way to dieAnlagen during
operation, ie under-voltage on possible defects zuprüfen out
to avoid a failure of the entire plant. Since this is the
search for hierbeium overheated components or wiring, is the
theme of Fire nahe.Es today are different infrared cameras
on the market, covering various fields of application.
Accordingly, OHIM contends, would daßspeziell for use in the
investigation of medium and low voltage, not all infrared
cameras in question, warns in Hanover Juergen Tietke,
Technical Office for thermography. With today's cameras
could be used but Temperaturenvon record -20 ° C to 2000 ° C
with an accuracy of 0.1 ° C. For operations in the interior
and exterior, there are lenses that detect heat even at
great distances. Infrared measurements today typically offer
specialized engineering companies. The purchase of a camera
for an industrial plant itself is useful only in individual
cases, as in Cologne, the association of life insurers, as
it aimed for the infrared imaging camera is usually an
operation needs only a few days a year gebe.Der price of the
service and the related report After the nature and scope
and the number of vulnerabilities found. preparations for
the examination are necessary because of glass and acrylic
Thermographic inspection elektrischenAnlagen measurements
could be carried out at all voltage levels. The non-contact
testing this would prove to be of great advantage to ensure
a secure smooth production. The following measurements,
these include: low-voltage switchgear, switchboards,
lighting systems, compressor systems, compensation systems,
emergency systems, interior switchgear, switchyard,
Hochstromanlagen. For examination of electrical equipment
are suitable thermal imaging systems of the companies FSI
Flir Systems, Inframetrix, country Minolta, Nikon and
Jenoptik.
