Description
Technical field
The utility model relates to generator field shielding construction field, specifically discloses 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.
Utility model content
Goal of the invention of the present utility model is: 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 scheme that the utility model adopts is such:
Generator neutral point wall barricade structure, it is fixed on surface of wall, comprises channel-section steel, iron plate, insulation board, 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 insulation board between described aluminium sheet and iron plate, this insulation board 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 insulating sheath.
Further, described barricade plate width length is 2000mm, and width is 750mm.
In sum, owing to adopting technique scheme, the beneficial effects of the utility model are: 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.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged diagram of I in Fig. 1.
Mark in figure: 1, body of wall; 2, channel-section steel; 3, iron plate; 4, insulation board; 5, aluminium sheet; 6, T-shaped bolt insulating sheath.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1 ~ 2, generator neutral point wall barricade structure, it is fixed on body of wall 1 surface, comprises channel-section steel 2, iron plate 3, insulation board 4, aluminium sheet 5, and described channel-section steel 2 is fixed on body of wall 1 surface by expansion bolt; Described iron plate 3 is with described channel-section steel 2 by being welded and fixed, and the position of described channel-section steel 2 is the edge of iron plate 3, so that Site Welding; In the inner side of described iron plate 3, the one side of pressing close to body of wall 1 is welded with some nuts, and transverse and longitudinal rule is arranged, and relevant position offers screw, is fixedly welded on iron plate 3 in advance before iron plate 3 and channel-section steel 2 are welded and fixed by nut; Described aluminium sheet 5 to be coordinated with the top nut of described iron plate 3 by some bolts to be fixed both, and this bolt place is provided with T-shaped bolt insulating sheath 6, to regulate the stress of thermal expansion; This bolt bearing, be provided with insulation board 4 between described aluminium sheet 5 and iron plate 3, this insulation board 4 is grown up bar shaped, laterally arranged in parallel; Described barricade plate width length is 2000mm, and width is 750mm, and it is overall for splicing soldering and sealing during in-site installation.
In use, avoid construction bolt the most nearby at generator neutral point conductor, ensure that barricade is not less than 220mm to the safe distance of conductor simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
