Abstract
The utility model provides a distribution box comprising a box body, components installed in the box body, a door plate and a sealing element, wherein the box body is provided with a wire inlet for cables to penetrate; the wire inlet is fixedly provided with a corresponding cable sheath; the cable sheath passes through the corresponding wire inlet; and the outer periphery of the cable sheath is hermetically matched with the inner periphery of the wire inlet. As the wire inlet is fixedly provided with the corresponding cable sheath, the cable sheath passes through the corresponding wire inlet, and the outer periphery of the cable sheath is hermetically matched with the inner periphery of the wire inlet, the cables can be protected and prevented from scratch. Therefore, the safety of the distribution box is ensured and the service life of the distribution box is prolonged.
Description
Technical field
The present invention relates to a kind of distribution box, particularly a kind of distribution box that is used for the nuclear power environment belongs to the power transmission and distribution technical field.
Background technology
Distribution box be by the electrical wiring requirement be assembled in switchgear, measuring instrument, protection electrical equipment and auxiliary equipment in sealing or the semiclosed metal cabinet or the screen width of cloth on and constitute power distribution equipment.Extensively be adapted in each power station, distribution substation, electric substation, industrial and mining enterprises, the construction place.
Distribution box of the prior art comprises casing, is installed in the components and parts in the casing, door-plate, and hinge, door lock, casing are provided with the through hole that is used to pass cable.The distribution box of this structure, because the through hole on the casing directly contacts with cable, when cable passed through hole, the insulating barrier of cable was scratched by the burr at through hole edge easily, influences the fail safe of distribution box; And through hole does not have any sealing, door-plate is poorly sealed, the casing manufacture craft is poor, and in the distribution box use, dust or moisture carry out in the casing easily, components and parts and annex select performance more general in the case simultaneously, make components and parts impaired, decreased performance is big, thereby, greatly reduce the useful life of distribution box, and influence the fail safe of distribution box; Can not satisfy the distribution requirement in nuclear power station place.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of security performance is good, long service life, distribution box simple in structure and easy to process, can use in that nuclear power plant environment is medium-term and long-term simultaneously.
In order to solve the problems of the technologies described above, a kind of distribution box of the present invention, comprise casing, be installed in the components and parts in the casing, door-plate and seal, described casing is provided with the entrance hole that is used to pierce into cable, and wherein, described entrance hole is fixed with corresponding cable cover(ing), described cable cover(ing) passes corresponding described entrance hole, and described cable cover(ing) outer peripheral face and described entrance hole inner peripheral surface are sealed and matched.
Above-mentioned a kind of distribution box wherein, is fixed with sealing strip on the described door-plate inner surface.Above-mentioned a kind of distribution box, wherein, described sealing strip is that silicon rubber processes.
Above-mentioned a kind of distribution box, wherein, described casing comprises side plate, base plate and top board, described side plate, described base plate and described top board are welded to connect by no breakpoint and are integral.
The present invention can realize following beneficial effect:
1, because described entrance hole is fixed with corresponding cable cover(ing); described cable cover(ing) passes corresponding described entrance hole; described cable cover(ing) outer peripheral face and described entrance hole inner peripheral surface are sealed and matched; can protect cable; avoid cable to be scratched; thereby, guaranteed the fail safe of distribution box, prolonged the useful life of distribution box.
2, because described door-plate is provided with sealing strip, can prevent that dust from entering distribution box, components and parts are caused wearing and tearing, thereby, the useful life of further having improved distribution box.
3, because sealing strip is a silicon rubber, not only can seal casing, and, because silicon rubber has good insulation, also can prevent the potential safety hazard brought owing to cable bad, thereby, further prolong the useful life of distribution box, improved the fail safe of distribution box.
4, because described casing comprises side plate, base plate and top board, described side plate, described base plate and described top board are welded to connect by no breakpoint and are integral, can avoid liquid to infiltrate in the distribution box, components and parts are caused damage, thereby, further improve the fail safe of distribution box, and further prolonged the useful life of distribution box.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of casing of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in the figure, in order to solve the problems of the technologies described above, a kind of distribution box of the present invention, comprise casing 1, be installed in the components and parts in the casing, door-plate 7, described casing 1 is provided with the entrance hole 3 that is used to pierce into cable 2, components and parts are selected internationally renowned brand for use, annex adopts the product that meets the nuclear power station requirement, described entrance hole 3 is fixed with corresponding cable cover(ing) 4, and described cable cover(ing) 4 passes corresponding described entrance hole 3, and described cable cover(ing) 4 outer peripheral faces and described entrance hole 3 inner peripheral surfaces are sealed and matched, the quantity of cable cover(ing) 4 is unrestricted, according to the quantity specific design of entrance hole 3.Because described entrance hole 3 is fixed with corresponding cable cover(ing) 4; described cable cover(ing) 4 passes corresponding described entrance hole 3; described cable cover(ing) 4 outer peripheral faces and described entrance hole inner peripheral surface are sealed and matched; can protect cable; avoid cable to be scratched; thereby, guaranteed the fail safe of distribution box, prolonged the useful life of distribution box.
As a further improvement on the present invention, in order further to improve useful life of the present invention, can on described door-plate 7 inner surfaces, be fixed with sealing strip 5 by stick or other modes, because described door-plate 7 is provided with sealing strip 5, guarantee that when door-plate 7 cuts out sealing strip 5 is pressed into 2mm at least, can prevent that dust from entering distribution box, components and parts are caused wearing and tearing, thereby, the useful life of further having improved distribution box.The material of sealing strip 5 is unrestricted; carry out designing institute according to concrete needs; in the present embodiment; in order further to improve fail safe of the present invention; described sealing strip 5 can be preferably silicon rubber processes; the shape of sealing strip 5 is unrestricted, can be shaped as frame, also can be planar plate members; because described sealing strip 5 processes for silicon rubber; not only can protect cable, and, because silicon rubber has good insulation; also can prevent the potential safety hazard brought owing to cable bad; thereby, further prolonged useful life of distribution box, the fail safe that has improved distribution box.
