METHOD FOR GROUNDING SWITCHGEAR DRAW-OUT TRUCK AND GROUNDING CONNECTION FOR SWITCHGEAR DRAW-OUT TRUCK

摘要

FIELD: electrical engineering; grounding switchgear trucks. ^ SUBSTANCE: proposed method for grounding switchgear truck includes wheeling draw-out truck that carries grounding connection into switchgear cubicle; grounding connection has base with holes to secure it to draw-out track, case, and segment part with segments for engaging switchgear bus. Novelty is that grounding connection is made in the form of spring member with two bend sections of which one is provided in region of case transfer to segment part and other one is disposed in vicinity of segments so that case and segment part occur in plane perpendicular to base. Spring member is made of rolled iron. ^ EFFECT: enhanced reliability, safety, and manufacturability of grounding connection, reduced material input. ^ 6 cl, 9 dwg
