- LV 11378 Izgudrojuma formula 1. Vēja elektroiekārtas kontroles paņēmiens, kura būtība ir tāda, ka ar signālu optisko pārveidošanu izmēra informatīvo parametru vērtības, tās salīdzina ar pieļaujamām vērtībām un formē kontroles rezultātus, atšķiras ar to, ka, ar mērķi paplašināt kontroles funkcionālās iespējas, kā papildus informatīvo parametru izmanto darbojošās vēja elektroiekārtas pamatelementu mehānisko svārstību paātrinājumu.
- 2. Ierīce vēja elektroiekārtas kontrolei,lai īstenotu paņēmienu pēc p.1 , satur šķiedras optisko kabeli, kas plaši kontaktē ar vēja elektrisko iekārtu un kura gali ir pieslēgti gaismas diodei un fotouztvērējam, pie tam fotouztvērējs ir savienots ar izpildelementu caur sliekšņa pastiprinātāju, un atšķiras ar to, ka, ar mērķi paplašināt funkcionālās iespējas un novērst avārijas situācijas, šķiedras optiskais kabelis kontroles iecirkņos ir pārgriezts, pie kam katrā iecirknī viena kabeļa daļa, kas atrodas griezuma vienā pusē, ir stingi savienota ar vēja elektroiekārtas kontrolējamo iecirkni, bet otra daļa, kas atrodas griezuma otrā pusē, savienota ar iekārtu caur elestīgu starpsienu tā, ka abi kabeļa gali ir kontaktā un to asis sakrīt, kad nav gaismasvada vibrāciju.
