Problems solved by technology
In the distribution box of this structure, since the through hole on the box body is in direct contact with the cable, when the cable passes through the through hole, the insulation layer of the cable is easily scratched by the burr on the edge of the through hole, which affects the safety of the distribution box; There is no seal in the hole, the door panel is not tightly sealed, and the manufacturing process of the box is poor. During the use of the distribution box, dust or moisture is easy to enter the box. The drop is large, thereby greatly reducing the service life of the distribution box and affecting the safety of the distribution box; it cannot meet the power distribution requirements of the nuclear power plant site

Embodiment Construction
[0016] As shown in the figure, in order to solve the above technical problems, a distribution box of the present invention includes a box body 1, components installed in the box body, and a door panel 7. The box body 1 is provided with an inlet for passing through the cable 2. Wire hole 3, the components are selected from internationally renowned brands, and the accessories are made of products that meet the requirements of nuclear power plants. The wire inlet hole 3 is fixed with a corresponding cable sheath 4, and the cable sheath 4 passes through the corresponding wire inlet hole 3. The outer peripheral surface of the cable sheath 4 is in sealing fit with the inner peripheral surface of the wire inlet hole 3 , and the number of the cable sheath 4 is not limited, and is specifically designed according to the number of wire inlet holes 3 . Since the wire inlet hole 3 is fixedly provided with a corresponding cable sheath 4, the cable sheath 4 passes through the corresponding wi...

The invention provides a distribution box, which comprises a box body, elements arranged in the box body, a door plate and a sealing element, wherein an incoming hole through which a cable penetrates is arranged in the box body and is fixedly provided with a corresponding cable sheath which penetrates through the corresponding incoming hole; and the outer circumferential surface of the cable sheath is matched with the inner circumferential surface of the incoming hole in a sealing manner. The corresponding cable sheath is fixedly arranged in the incoming hole and penetrates through the corresponding incoming hole, and the outer circumferential surface of the cable sheath is matched with the inner circumferential surface of the incoming hole in a sealing manner, so that the cable can be protected and is prevented from being scratched and further the safety of the distribution box can be ensured and the service life of the distribution box can be prolonged.
Description
technical field [0001] The invention relates to a distribution box, in particular to a distribution box used in a nuclear power environment, and belongs to the technical field of power transmission and distribution. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width to form power distribution equipment. It is widely used in various power stations, power distribution stations, substations, industrial and mining enterprises, and construction sites. [0003] The distribution box in the prior art includes a box body, components installed in the box body, a door panel, a hinge, and a door lock, and the box body is provided with through holes for passing cables. In the distribution box of this structure, since the through hole on the box body is in direct contact with the cable, when the cable passes t...
