LINEAR AUTOMATIC CIRCUIT BREAKER AND MAGNETIC YOKE FOR LINEAR AUTOMATIC CIRCUIT BREAKER Russian patent published in 2010 - IPC H01H71/40 H01H73/66 

FIELD: electricity.

SUBSTANCE: invention relates to linear automatic circuit breaker with combined splitter of maximum current and short-circuit current, in which splitting in case of maximum current and short-circuit current should be executed precisely as specified. In order to achieve this, distances of its elements from anchor should be accurately adjusted. However, if the vessel consists of efficient material for vessels, such as Duroplast, than it shrinks. Specified distances vary as a result. According to invention, on one side the anchor (24) is installed so that whenever the vessel shrinks, it changes its initial rotary position. Magnetic yoke (28) as part of maximum current and short-circuit current splitter is installed and has such a shape that specified distances do not change, in spite of vessel shrinkage.

EFFECT: development of cheap structure, provides for reliable thermal and magnetic splitting.
