Abstract

The invention relates to a device for checking an internal surface of an oil conservator fitting out a power transformer. According to the invention, the device comprises a flexible rod (1) at the lower end whereof there is mounted a magnifier light bulb (2) supplied with electric current from a battery (3) by means of a switch (4), on the same rod (1), above the bulb (2), there being placed a video camera (5), which, by means of a cable (6), transmits the image of the surface of an internal wall of the oil conservator to a laptop computer (7).

Description

Invenția se referă la un dispozitiv pentru verificarea suprafețelor interioare ale conservatoarelor de ulei, pentru depistarea eventualelor degradări apărute în timpul exploatării.The invention relates to a device for checking the inner surfaces of oil preservatives, for detecting possible degradation that occurred during operation.

Este cunoscut un dispozitiv pentru verificarea suprafețelor interioare (JP 55117946 A), prevăzut cu un cap de inspecție optic care este introdus într-un arbore tubular de verificat. Lumina generată de o sursă de lumină este reflectată de două ori la 90° de două oglinzi, trece printr-o lentilă biconvexă, este proiectată pe suprafața interioară a arborelui tubular și este reflectată de suprafața interioară a arborelui tubular pe suprafața exterioară a capului optic pe un senzor, obținându-se un semnal care se trimite la o unitate de procesare.A device for checking interior surfaces (JP 55117946 A), provided with an optical inspection head, is inserted into a tubular shaft to be checked. The light generated by a light source is reflected twice at 90 ° by two mirrors, passes through a biconvex lens, is projected on the inner surface of the tubular shaft and is reflected by the inner surface of the tubular shaft on the outer surface of the optical head on a sensor, obtaining a signal that is sent to a processing unit.

Acest dispozitiv de verificare a suprafețelor interioare prezintă dezavantajul că are o construcție complicată.This device for checking the interior surfaces has the disadvantage that it has a complicated construction.

Mai este cunoscut un dispozitiv pentru verificarea suprafețelor interioare, ce face obiectul cererii de brevet de invenție OSIM a 2009 00620, care are ca sursă de lumină un bec cu lupă alimentat cu o baterie, care poate fi comandat printr-un întrerupător.Also known is a device for checking interior surfaces, which is the subject of OSIM patent application 2009 00620, which has as a light source a bulb with a magnifying glass powered by a battery, which can be controlled by a switch.

Acest dispozitiv de verificare a suprafețelor interioare prezintă și el dezavantajul că are o construcție complicată.This device for checking interior surfaces also has the disadvantage that it has a complicated construction.

Problema tehnică pe care o rezolvă invenția este observarea eventualelor pete de rugină, care pot să apară în interiorul conservatoarelor transformatoarelor de putere, datorită acțiunii corozive a aerului și a umezelii, fără a fi necesară demontarea unui perete lateral al conservatorului.The technical problem solved by the invention is the observation of possible rust spots, which may occur inside the conservatories of power transformers, due to the corrosive action of air and moisture, without the need to dismantle a side wall of the conservator.

Dispozitivul pentru verificarea suprafețelor interioare rezolvă problema tehnică menționată anterior, prin aceea că are o tijă flexibilă, pe care la capătul inferior este montată o cameră video, care preia imaginea suprafeței interioare a piesei de controlat, de tip tubular, și o transmite printr-un cablu pe ecranul unui calculator portabil.The device for checking the inner surfaces solves the aforementioned technical problem, by having a flexible rod, on which at the lower end is mounted a video camera, which takes the image of the inner surface of the control piece, of tubular type, and transmits it through a cable on the screen of a laptop.

Dispozitivul pentru verificarea suprafețelor interioare, conform invenției, prezintă următoarele avantaje:The device for checking the interior surfaces, according to the invention, has the following advantages:

- are fiabilitate ridicată;- has high reliability;

- simplitate constructivă.- constructive simplicity.

Se dă în continuare un exemplu de realizare a invenției, în legătură cu figura care reprezintă o secțiune transversală prin dispozitivul pentru verificarea suprafețelor interioare.Following is an example of an embodiment of the invention, in connection with the figure representing a cross-section through the device for checking the interior surfaces.

Dispozitivul pentru verificarea suprafețelor interioare, conform invenției, este constituit dintr-o tijă flexibilă 1, prevăzută la capătul inferior, pentru iluminarea suprafețelor interioare ale piesei de controlat de tip tubular, cu un bec cu lupă 2, alimentat cu o baterie 3, care poate fi comandat printr-un întrerupător 4, dispuse la capătul superior al tijei flexibile 1. Tot la capătul inferior al tijei flexibile 1, este plasată o cameră video 5, care preia imaginea suprafeței interioare a piesei de controlat de tip tubular și o transmite printr-un cablu 6 pe ecranul unui calculator portabil 7. Cu acest dispozitiv se pot depista petele de rugină apărute în interiorul piesei de controlat de tip tubular.The device for checking the inner surfaces, according to the invention, consists of a flexible rod 1, provided at the lower end, for illuminating the inner surfaces of the tubular type control part, with a magnifying glass bulb 2, powered by a battery 3, which can be controlled by a switch 4, disposed at the upper end of the flexible rod 1. Also at the lower end of the flexible rod 1, a video camera 5 is placed, which takes the image of the inner surface of the control piece of tubular type and transmits it through a cable 6 on the screen of a portable computer 7. With this device you can find the rust spots that appear inside the control piece of tubular type.
