ARC SUPPRESSION REACTOR WITH ADJUSTABLE MAGNETIC GAP Russian patent published in 2017 - IPC H01F29/10 H02H9/00 H02J3/18 

FIELD: electricity.

SUBSTANCE: in reactor the current indicator 15 is made mechanical, and its housing (20) is made in the form of a cylinder fixed on the rotation axis 22. The bottom of the housing 20 represents a gear wheel 21 by which the current indicator 15 is kinematically connected to the magnetic gap regulator shaft 9 in such a way that the linear movement of the cores 4 and 5 is converted into the rotational movement of the housing 20. The current indicator 15 is provided with the first 24 and the second 25 locking contacts, which are fixed with the possibility to interact with the corresponding 17 and 18 limit switches of locking the end positions of the cores 4 and 5 of the magnetic circuit 3. On the side surface of the cylinder of the housing 20 of the current indicator 15, a measuring scale 34 is plotted, graduated in amperes. Coaxially with the rotation axis 22 of the housing 20 of the current indicator 15 the variable resistor 26 is fixed, to the terminals of which wires are soldered. The resistor axis rotates synchronously with the housing of the current indicator. As a result, visual and remote monitoring of the reactor current is organized. Additionally, the air drier 41 is introduced, through which the internal cavity of the reactor is communicated with the atmosphere.

EFFECT: increased reliability, improved operating conditions and simplified maintenance.
