Description

Pokiaľ je to žiadúce, môže byť bočníkový prvok jemne sústružený alebo brúsený po výrobe, aby sa presne nastavila jeho hodnota. Zvyčajne však bude táto hodnota zmeraná presne a použitá na získanie presných prúdových hodnôt z napätia meraného na bočníku.

Claims (5)

  1. PATENTOVÉ NÁROKY
    1. Bočníková zostava na meranie prúdu, v y z n a č u j ú c a sa tým, že zahrnuje bočníkový prvok (12) v podstate valcového tvaru a z materiálu s nulovým teplotným súčiniteľom, ktorý má dvojicu prúdových vývodov v tvare plochých pásov (10,11) pripevnených k jeho koncom.
  2. 2. Bočníková zostava podľa nároku 1,vyznačujúca sa tým, že ku koncom bočníkového prvku sú pripojené cez otvory v prúdových vývodoch (10, 11) meracie vývody (13, 14) z rovnakého materiálu s nulovým teplotným súčiniteľom.
  3. 3. Bočníková zostava podľa nároku 2, vyznačujúca sa tým, že meracie vývody (13, 14) tvoria časť kontinuálneho drôtika prechádzajúceho cez axiálny otvor (17) cez bočníkový prvok (12).
  4. 4. Bočníková zostava podľa nároku 2, vyznačujúca sa tým, že meracie vývody (13, 14) sú vytvorené ako intergálne predĺženie bočníkového prvku.
  5. 5. Akýkoľvek nový a vynálezcovský znak alebo kombinácia znakov špecificky opísaná v tomto opise v zmysle článku 4H medzinárodnej dohody (Parížska dohoda).
