High-tension switch cabinet is when to A phase, B phase and C phase three busbar stube cables, the cable trough below by high-tension switch cabinet is needed to be upward through the base plate of high-tension switch cabinet, at present, the base plate of high-tension switch cabinet is provided with a cable and penetrates hole, if the sectional area of three core high-voltage cables is at 50mm
2below, relatively goodly penetrate hole by cable, but along with the growth of load in present shop, the increase of power consumption, the cross-section of cable is long-pending also in increase, particularly 300mm
2, 400mm
2cable, be no matter copper core, aluminium core cable all very hard, add the limited space in high-tension switch cabinet, quite difficult in the connection with three-phase bus bar, time-consuming.In addition, three core high-voltage cables are when upwards penetrating hole by cable by cable trough, and because three cores are together relatively thicker, the insulation sheath of easy core and base plate friction, destroy the insulating barrier of core.
Utility model content
The utility model in order to solve weak point of the prior art, provide a kind of structure simple, be easy to wiring, security reliability, time saving and energy saving 10kV high-tension switch cabinet high-voltage busbar wiring construction.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: 10kV high-tension switch cabinet high-voltage busbar wiring construction, comprise high-tension switch cabinet and be positioned at the cable trough below high-tension switch cabinet, A phase connection busbar is provided with in high-tension switch cabinet, B phase connection busbar and C phase connection busbar, three core high-voltage cables are laid with in cable trough, the base plate of described high-tension switch cabinet be provided with respectively with A phase connection busbar, B phase connection busbar and upper and lower the first corresponding through hole of C phase connection busbar, second through hole and third through-hole, first heart yearn of three core high-voltage cables, second heart yearn and the 3rd heart yearn are upward through the first through hole respectively, second through hole and third through-hole are corresponding to A phase connection busbar, B phase connection busbar is connected with C phase connection busbar.
The inwall of described first through hole, the second through hole and third through-hole is provided with flexible insulation cover, edge, flexible insulation set upper side is provided with spacing ring, the external diameter of flexible insulation cover equals the internal diameter of the first through hole, the second through hole and third through-hole, spacing ring external diameter is greater than the internal diameter of the first through hole, the second through hole and third through-hole, and the first heart yearn, the second heart yearn and the 3rd heart yearn be the corresponding endoporus through flexible insulation cover respectively.
Adopt technique scheme, three core high-voltage cables in the middle of the utility model can just the first heart yearn in cable trough, second heart yearn and the 3rd heart yearn strip out, then by the first heart yearn, second heart yearn and the 3rd heart yearn are upward through the first through hole respectively, second through hole and third through-hole, then three flexible insulation covers are enclosed within the first heart yearn respectively, on second heart yearn and the 3rd heart yearn and to slipping down to the first through hole, in second through hole and third through-hole, spacing ring stops flexible insulation, make flexible insulation overlap all the time with the first through hole, second through hole and third through-hole contact internal walls, because base plate is thinner, flexible insulation cover can avoid the first heart yearn, second heart yearn directly contacts with base plate the insulation sheath cutting heart yearn with the 3rd heart yearn, play good safety protection function.The setting of spacing ring can avoid flexible insulation cover to fall in cable trough.
Certainly, cables manufacturing producer also directly can produce the high-tension cable of single core, and the high-tension cable of three single cores is connected with A phase connection busbar, B phase connection busbar and C phase connection busbar respectively.
The utility model structure is simple, reasonable in design, is easy to operation, time saving and energy saving, and security reliability is high, practical, is easy to apply.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, 10kV high-tension switch cabinet high-voltage busbar wiring construction of the present utility model, the cable trough 2 comprising high-tension switch cabinet 1 and be positioned at below high-tension switch cabinet 1, A phase connection busbar 3 is provided with in high-tension switch cabinet 1, B phase connection busbar 4 and C phase connection busbar 5, three core high-voltage cables 6 are laid with in cable trough 2, the base plate 12 of described high-tension switch cabinet 1 be provided with respectively with A phase connection busbar 3, first through hole of B phase connection busbar 4 and C phase connection busbar about 5 correspondence, second through hole and third through-hole, first heart yearn 7 of three core high-voltage cables 6, second heart yearn 8 and the 3rd heart yearn 9 are upward through the first through hole respectively, second through hole and third through-hole are corresponding to A phase connection busbar 3, B phase connection busbar 4 is connected with C phase connection busbar 5.
The inwall of the first through hole, the second through hole and third through-hole is provided with flexible insulation cover 10, flexible insulation overlaps 10 edges, upper end and is provided with spacing ring 11, the external diameter of flexible insulation cover 10 equals the internal diameter of the first through hole, the second through hole and third through-hole, spacing ring 11 external diameter is greater than the internal diameter of the first through hole, the second through hole and third through-hole, and the first heart yearn 7, second heart yearn 8 and the 3rd heart yearn 9 be the corresponding endoporus through flexible insulation cover 10 respectively.
Three core high-voltage cables 6 in the middle of the utility model can just the first heart yearn 7 in cable trough 2, second heart yearn 8 and the 3rd heart yearn 9 strip out, then by the first heart yearn 7, second heart yearn 8 and the 3rd heart yearn 9 are upward through the first through hole respectively, second through hole and third through-hole, then three flexible insulation covers 10 are enclosed within the first heart yearn 7 respectively, on second heart yearn 8 and the 3rd heart yearn 9 and to slipping down to the first through hole, in second through hole and third through-hole, spacing ring 11 stops flexible insulation, make flexible insulation overlap 10 all the time with the first through hole, second through hole and third through-hole contact internal walls, because base plate 12 is thinner, flexible insulation cover 10 can avoid the first heart yearn 7, second heart yearn 8 directly contacts with base plate 12 insulation sheath cutting heart yearn with the 3rd heart yearn 9, play good safety protection function.The setting of spacing ring 11 can avoid flexible insulation cover 10 to fall in cable trough 2.
