Opis:Description:
Priključni element posega v področje elektrotehnike v smislu varstva pri delu.The connecting element encroaches on the field of electrical engineering in terms of occupational safety.
Večni problem pri vzdrževalnih delih v nizkonapetostnem kabelskem omrežju ali nizkonapetostnem omrežju s samonosilnimi kabelskimi snopi je ozemljevanje in kratkostikanje priključkov v nizkonapetostnih stikalnih blokih in nizkonapetostnih razdelilnih omaricah, ki so priključeni na varovalna podnožja ali varovalne letve.A major problem with maintenance work on a low-voltage cable network or a low-voltage network with self-supporting wiring harnesses is to ground and short-circuit the terminals in the low-voltage switchgear and low-voltage distribution boxes that are connected to the protective sockets or fuses.
Težave nastopijo zaradi premalo razpoložljivega prostora pri priključnih mestih. Priključne sponke, ki jih izdeluje Mehanika” Trbovlje v te namene, ni možno uporabiti tako, da je kvaliteta in zanesljivost stika in ozemljevanja prepuščena iznajdljivosti in strokovnosti posameznika. Postopek ozemljevanja in kratkega stikanja je eno od petih zlatih pravil pri vzdrževanju elektroenergetskih naprav, in te so:Problems arise due to insufficient space available at the connection points. The terminal blocks made by Trbovlje Mechanics for these purposes cannot be used in such a way that the quality and reliability of contact and earthing are left to the ingenuity and professionalism of the individual. The earthing and short-circuiting process is one of the five golden rules for maintaining electrical appliances, and these are:
1. Izklopi napravo iz vseh smeri1. Turn off the device from all directions
2. Onemogoči ponovni priklop naprave2. Disables reconnecting the device
3. Prepričaj se, če je naprava brez napetosti3. Make sure the device is unplugged
4. Napravo ozemlji in kratko stakni4. Ground the device and short the window
5. Napravo zavaruj od delov pod napetostjo.5. Secure the device against live parts.
Rešitev opisanega problema je prikazana na sliki 1. Element je sestavljen iz pregoretega-neuporabnega varovalnega vložka, tipa NV 1.1., priključnega vijaka 1.3. in izolacije 1.2., kot je prikazano na sliki 1.The solution to the problem described is shown in Figure 1. The element consists of a burnt-out usable guard insert, type NV 1.1., A connecting screw 1.3. and insulation 1.2., as shown in Figure 1.
Pred sestavo je potrebno:Before assembly, it is necessary to:
- varovalnemu elementu tipa NV, ki je sestavljen iz keramičnega telesa kvadraste oblike in na katerega sta z obeh strani pritrjena kontaktna elementa, očistiti ostanke talilnih elementov varovalke ter odstraniti kvarčni pesek;- a NV type safety element consisting of a quad shaped ceramic body and to which contact elements are attached on both sides, to clean the remains of the fuse elements of the fuse and to remove quartz sand;
- izdelati utor v keramično telo varovalnega vložka s pomočjo diamantne rezalne plošče. Utor se izdela na tisti strani, kjer se bo montiral priključni vijak. Lega utora se vidi na sliki 1;- Make a groove into the ceramic body of the retaining insert using a diamond cutting board. The groove is made on the side where the connecting screw will be mounted. The position of the groove can be seen in Figure 1;
- priključnemu vijaku, ki je izdelek Mehanika Trbovlje, je potrebno posneti izolacijo v dolžini 50 mm in ga skrajšati za 10 mm na strani brez navoja. Priključni vijak je izdelan iz Cu, je galvansko posrebren in izoliran;- the connection screw, which is a product of Trbovlje Mechanics, must be insulated 50 mm long and shortened by 10 mm on the threaded side. The connecting screw is made of Cu, galvanized and insulated;
- v kontaktni del, ki ga bomo ožemijevali, se izvrta luknja premera 7,5 mm v neposredni bližini pritrdilne ploščice s katero pritrdimo preko vijakov kontakt na nosilno ploščico. Le-ta je pritrjena na keramično telo varovalnega vložka. Luknja je potrebna za prehod neizoliranega dela priključnega vijaka in s tem zagotavljanja kvalitetnega galvanskega spoja.- A hole of 7.5 mm diameter is drilled into the contact part to be screwed in, in the immediate vicinity of the mounting plate, by which the contact is fixed to the mounting plate. It is attached to the ceramic body of the protective insert. The hole is required for the passage of the non-insulated part of the connecting screw and thus ensuring a high-quality galvanic joint.
Galvanski spoj med priključnim vijakom in kontaktom varovalnega vložka izvedemo s pomočjo dveh vijakov M 5x20, navadnih, vzmetnih podložk in navojev, ki so že izdelani na pritrdilni ploščici kontakta ali s spojkanjem.The galvanic connection between the connecting screw and the contact of the protective insert is made by means of two M 5x20 screws, plain, washers and threads already made on the contact mounting plate or by coupling.
