FIELD: electrical engineering; switchgear and control gear cabinets with protective gear. ^ SUBSTANCE: switchgear and control gear cabinet 1 is divided by means of partition 2 into compartment 3 accommodating draw-out component 6 and adjacent collecting-buses compartment 4. Phase leads 5 of circuit breaker installed in draw-out component 6 are connected to collecting buses by lifting draw-out component of compartment 3. For the purpose holes 7 are provided in partition 2, their diameter being greater than that of circuit-breaker phase leads 5. Shutter mechanism characterized in simplified design incorporates shutter 8 in the form of panel with holes 9 for passing circuit-breaker phase leads 5. Shutter 8 is mounted for displacement relative to partition 2 in parallel plane. ^ EFFECT: simplified design, enhanced reliability and reduced size of cabinet. ^ 5 cl, 4 dwg |
