OFF-LINE POWER SUPPLY FOR DOWNHOLE INSTRUMENTS Russian patent published in 2003 - IPC

Abstract RU 2206149 C2

FIELD: electrical engineering; feeding downhole equipment in boring oil and gas wells. SUBSTANCE: off-line power supply that has nonmetal case accommodating power cells interconnected by means of conductors is proposed to be made flexible and oval-shaped for transformation into round shape when installing power cells with longitudinal slits. Internal shock absorbers are installed between cells and nonmetal case is closed with end plates on both ends which mount external shock absorbers. EFFECT: enhanced operating reliability of power supply under impact loads. 5 cl, 5 dwg
