Στην παρούσα εργασία ασχοληθήκαμε με τα ηλεκτροτεχνικά υγρά, τόσο θεωρητικά όσο και πειραματικά. Σε θεωρητικό επίπεδο περιγράφουμε το ρόλο των μονωτικών λαδιών, τις χρήσεις τους, τις ιδιότητές τους και τους παράγοντες που τα επηρεάζουν. Σε πειραματικό επίπεδο, πραγματοποιούμε πλήθος μετρήσεων με στόχο την εξακρίβωση και την εξαγωγή συμπερασμάτων από την εφαρμογή γραμμικώς αυξανόμενης a.c. τάσης πάνω σε δύο διαφορετικά είδη μονωτικών λαδιών. / As networks of High Voltage Alternate Power can be characterized those who
function in voltage higher than 1000V. Therefore, the electrological equipment which
is going to be settled and function in alternate power voltage higher than 1KV is
characterized as a High Voltage Equipment.
The insulation of the equipment and that of the high voltage establishments is
indispensable in order to maintain the potential difference between the under high
voltage conductible parts. Alongside its main destination, insulation may have other
roles too such as the mechanic support of the wire way, the exchange of temperature
e.c.t.
In the present project we dealt with the electro – technical liquids in
theoretical and also in experimental level.
According to the theoretical level, we described the role of the insulating oils,
their uses, their attributes and the factors that affect them.
According to the experimental level we accomplished a number of
measurements, having as intension the verification and the deduction of conclusions
coming from the application of the linearly ongoing a.c. voltage on two different kinds
of insulating oils.
From the aforementioned measurements we noticed the impact that the
length of the gap, the temperature, even the combination of the two different
insulating oils have on the tendency in breaking not only quantitavely (change of
size) but also qualitatively (change of statistical attributes).
For carrying out the experimental procedure we utilized the device of the High
Voltages Laboratory’s electrological equipment. All measurements and also the
selection of the appropriate testing prescription were done by this device, taking each
time the necessary safeguards for us and for the lab’s facilities.
Finally, the results were gathered in billboards and were farther analyzed
according to indispensable diagrams for the deduction of conclusions. In this point is
very important to mention that on those billboards is indicated the average value
which refers to the tendency in breaking and that of typical variations, just for
practical reasons.
