LEAD ACCUMULATOR Russian patent published in 2001 - IPC

FIELD: electrical engineering. SUBSTANCE: lead accumulator has unlike-polarity plates with separators in-between and plastic insulating strips on side edges of negative plates. Novelty is that insulating strips look in their section as projections of truncated isosceles triangle; ratio of smaller base width on inner dimension of this triangle to thickness of negative plate is chosen to equal 0.22 : 0.42 and ratio of width in inner dimension of larger base to smaller one is 3.0 : 3.75. Proposed insulating strips on edges of negative plates fully eliminate short circuits in the course of testing and operating lead accumulators. EFFECT: enhanced reliability and safety. 2 dwg
