Abstract
The utility model relates to a high heat-dissipating type and channel-type cable bridge special for nuclear power, and belongs to the technical field of low-voltage power transmission and distribution equipment accessories. The high heat-dissipating type and channel-type cable bridge special for the nuclear power comprises a cable bridge body, shutters type heat-dissipating holes are formed in two side plates of the cable bridge body at intervals, and steel meshes are formed in the inner sides of the heat-dissipating holes. Due to the fact that the shutters type heat-dissipating holes are formed in the high heat-dissipating type and channel-type cable bridge special for the nuclear power, the heat-dissipating effect in cable operations is improved. The manufacture of the shutters type heat-dissipating holes does not lead to the reduction of any materials, on the contrary, a plurality of strengthening ribs are formed on the side plates of the cable bridge, so that the strength and load of the cable bridge are improved. The holes formed in the side plates reduce the dustproof and waterproof protection level of the cable bridge. Compensation is made through the steel meshes arranged on the inner sides of the heat-dissipating holes. As a further improvement of the high heat-dissipating type and channel-type cable bridge special for the nuclear power, the heat-dissipating holes are distributed evenly in the side plates, so that even heat dissipation of operating cable is guaranteed.
Description
Technical field
The utility model belongs to low pressure equipment for power transmission and distribution attachment technique field, relates in particular to a kind of cable testing bridge.
Background technique
Cable testing bridge is to consist of the rigid construction system with intensive carrying cable by the straightway of pallet or ladder, curved logical, assembly and trailing arm, suspension bracket etc., be the staple product that electric power transfer is responsible in low pressure power transmission and distribution field, extensively be used at building and industrial and mineral, factories and miness place.If cable laying radiating effect in cable testing bridge is bad, the heating of cable emerged in operation, heating can cause the cable security current carrying capacity to descend, and cable long term high temperature operation meeting affects system and normally moves, and serious situation can cause security incident.Cables of nuclear power crane span structure particularly, closeness is higher, and thermal diffusivity is poorer.
At present, the mode of solution cable testing bridge heat dissipation problem is: the sheet metal thickness that reduces cable testing bridge; At cable testing bridge body upper punch circle or waist-shaped hole.The shortcoming of this dual mode is: reduced the intensity of cable testing bridge, load-carrying ability descends greatly; Requirement dustproof, waterproof that the security level of cable testing bridge can't reach all can't be satisfied the technical requirements of the cable testing bridge of nuclear island of nuclear power station part.
The model utility content
For above-mentioned technical problem, the utility model provides a kind of high strongly heat-dissipated nuclear power special-purpose trough type bridge frame.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, the special-purpose trough type bridge frame of a kind of high strongly heat-dissipated nuclear power comprises the crane span structure body, is interval with the louvre type radiation hole on the biside plate of described crane span structure body, is provided with Mild Steel Expanded Sheets in the inboard of described radiation hole.
Louvre type radiation hole on the crane span structure body, the radiating effect when having improved the cable operation; Make the louvre type radiation hole and do not reduce any material on the crane span structure body, formed a lot of stiffening rib at cable bridge rack side board on the contrary, strengthened intensity, the load of cable testing bridge; The side plate perforate has reduced that cable testing bridge is dustproof, the security level of waterproof, and the utility model remedies by in described radiation hole inboard Mild Steel Expanded Sheets being set.
As the further improvement of the special-purpose trough type bridge frame of the high strongly heat-dissipated nuclear power of the utility model, described radiation hole is evenly arranged at described side plate, guarantees operating cable heat radiation evenly.
Description of drawings
Accompanying drawing is the special-purpose trough type bridge frame form structure of the high strongly heat-dissipated nuclear power of the utility model schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is made and to be further specified.
As shown in the figure, the special-purpose trough type bridge frame of the high strongly heat-dissipated nuclear power of the utility model comprises crane span structure body 1, is interval with louvre type radiation hole 2 on the biside plate 3 of described crane span structure body 1, is provided with Mild Steel Expanded Sheets 4 in the inboard of described radiation hole.
The radiation hole 2 of punching louvre type on the biside plate 3 of crane span structure body 1, inboard place is welded with Mild Steel Expanded Sheets 4 dustproof, waterproof at the side plate radiation hole.The first, the special-purpose trough type bridge frame of the high strongly heat-dissipated nuclear power of the utility model, the radiation hole of punching louvre type on the drafting board, the radiating effect when having improved the cable operation; The second, the louvre type radiation hole of punching on the side plate does not reduce any material of cable testing bridge, has formed a lot of stiffening rib at cable bridge rack side board on the contrary, has strengthened intensity, the load of cable testing bridge.The 3rd, side plate radiation hole place is welded with Mild Steel Expanded Sheets dustproof, waterproof, has increased the security level of dustproof, the waterproof of cable bridge rack side board perforate.
As further optimization of the present utility model, described radiation hole 2 is evenly arranged at side plate 3, the uniform effect of dispelling the heat in the time of reaching like this cable operation.
Above embodiment's description is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
1. the one kind high special-purpose trough type bridge frame of strongly heat-dissipated nuclear power comprises the crane span structure body, it is characterized in that: be interval with the louvre type radiation hole on the biside plate of described crane span structure body, be provided with Mild Steel Expanded Sheets in the inboard of described radiation hole.
2. the special-purpose trough type bridge frame of described high strongly heat-dissipated nuclear power according to claim 1, it is characterized in that: described radiation hole is evenly arranged at described side plate.
