Abstract
The invention belongs to the technical field of generator magnetic field shielding structures, and concretely relates to a generator neutral wall shielding plate structure. The generator neutral wall shielding plate structure is fixed on the surface of a wall and comprises a channel steel, an iron plate, insulating plates, and an aluminum plate, wherein the channel steel is fixed on the surface of the wall by expansion bolts; the iron plate is fixed to the channel steel through welding; a plurality of nuts are welded on the inner side, adjacent to the wall, of the iron plate, and screw holes are formed in the corresponding positions; the aluminum plate is fixed with the iron plate by cooperation of a plurality of bolts and the nuts on the iron plate, and the insulating plates in the strip shape are arranged at the bolt fixation positions between the aluminum plate and the iron plate. The damage to a steel bar structure in the wall of a generator room by magnetic field generated by strong current during the operation process of the generator can be effectively avoided, and furthermore hidden safety trouble is avoided.
Description
Technical field
The present invention relates to generator field shielding construction field, specifically disclose a kind of generator neutral point wall barricade structure.
Background technology
Generator neutral point terminal and generator body of wall close, due to generator, to make an inspection tour electric current comparatively large, and the electromagnetic field of generation can produce larger heating to bar construction in body of wall, causes body of wall to generate heat for a long time softening pineization, bring certain potential safety hazard to power plant's operation.
Summary of the invention
The object of the invention is to: provide a kind of effectively can shield magnetic field that in operated generator process, powerful electric current produces to the generator neutral point wall barricade structure of the destruction of bar construction in machine room body of wall for overcoming the above problems.
The technical solution adopted in the present invention is such:
Generator neutral point wall barricade structure, it is fixed on surface of wall, comprises channel-section steel, iron plate, insulating slab, aluminium sheet, and described channel-section steel is fixed on surface of wall by expansion bolt; Described iron plate and described channel-section steel are by being welded and fixed; In the inner side of described iron plate, the one side of pressing close to body of wall is welded with some nuts, and relevant position offers screw; Described aluminium sheet to be coordinated with described iron plate top nut by some bolts to be fixed both, this bolt bearing, is provided with insulating slab between described aluminium sheet and iron plate, this insulating slab growth bar shaped.
Further, the position of described channel-section steel is the edge of iron plate.
Further, be bolted between described iron plate and described aluminium sheet, this bolt place is provided with T-shaped bolt insulation sleeve.
Further, described barricade plate width length is 2000mm, and width is 750mm.
In sum, owing to adopting technique scheme, the invention has the beneficial effects as follows: install this wall barricade structure at generator body of wall additional near generator neutral point terminal place, the heating of magnetic field to body of wall inside reinforcing bar effectively avoiding the larger tour electric current of generator to produce is softened, thus has stopped the generation of power plant potential safety hazard.
