However, this design has obvious deficiency: first, solid structure limits the heat dissipation area, leads to low heat dissipation efficiency;Second, the natural convection heat dissipation capacity is limited, difficult to deal with the heat generated when high load operation, and easily causes bus duct overheating, and then influences the normal operation of power system. SUMMARY

[0008] Further, the sidewall of the partition plate is evenly provided with wire clamp, and the inside of wire clamp is clamped with bus body, and the air hole is arranged in the inside of the gap of adjacent bus body.

[0009] Further, the both ends of the slot body structure are respectively provided with butt joint end one and butt joint end two, and the butt joint end one and butt joint end two are respectively provided with butt joint sheet one and butt joint sheet two connected with both ends of bus body.

[0010] Further, the bottom of the groove structure is uniformly provided with reinforcing ribs, and the two sides of the groove structure are uniformly provided with heat dissipation fins along the length direction of the groove structure, and the groove structure outside the heat dissipation fins is provided with a protective plate, and the width of the protective plate is greater than the width of the heat dissipation fin.

[0011] Further, the bottom of the groove structure is uniformly provided with reinforcing ribs, and the two sides of the groove structure are uniformly provided with heat dissipation fins along the length direction of the groove structure, and the groove structure outside the heat dissipation fins is provided with a protective plate, and the width of the protective plate is greater than the width of the heat dissipation fin.

[0012] The utility model provides a kind of intensive bus duct with good heat dissipation effect, compared with prior art, with significant technical advantages and positive effects, embodied in the following aspects:

[0013] By utilizing the partition plate to uniformly set line slot inside the groove structure, a series of small holes are designed on the partition plate, which significantly increases the heat dissipation area. The design of these holes not only fully utilizes the surface area of the bus duct, but also ensures the rapid dissipation of heat through reasonable hole size and distribution. Compared with traditional intensive bus duct, the utility model can provide higher heat dissipation efficiency under the premise of same volume and compact structure, effectively avoiding the problem of bus overheating caused by poor heat dissipation.

[0014] The size and distribution of the holes are carefully designed, and the interval equidistance setting method is adopted, which not only ensures the increase of heat dissipation area, but also does not weaken the mechanical strength of the bus duct. This design cleverly balances the contradiction between heat dissipation demand and structural strength, so that the bus duct can still withstand high mechanical load while having good heat dissipation performance, ensuring long-term stable operation of the bus duct.

[0015] The heat dissipation fan is added at both ends of the bus duct bottom, forming an efficient auxiliary heat dissipation system. Through forced convection, the heat dissipation efficiency is further improved. This design not only makes up for the deficiency of natural convection heat dissipation, but also quickly reduces the temperature inside the bus duct in high temperature environment, preventing electrical faults caused by high temperature.

[0016] The design of heat dissipation duct and bus mounting groove division effectively avoids dust entering the interior of the bus duct during convection heat dissipation. This design not only improves the cleanliness of the bus duct, but also reduces the risk of heat dissipation performance degradation and electrical failure caused by dust accumulation, prolonging the service life of the bus duct.

[0017] Due to the significant improvement of heat dissipation effect, the temperature inside the bus duct is effectively controlled, thereby reducing the aging speed of electrical components and improving the reliability and stability of the entire electrical system. This is particularly important for electrical equipment that needs to run continuously for a long time, which can significantly reduce maintenance cost and downtime.

[0018] By optimizing the heat dissipation design, the energy loss caused by poor heat dissipation is reduced, and the energy utilization efficiency is improved. At the same time, the introduction of forced convection heat dissipation system can realize efficient heat dissipation under lower energy consumption, which meets the environmental protection requirements of energy saving and emission reduction.

[0019] In summary, the utility model discloses a porous structure partition plate and the auxiliary heat dissipation system of innovative design, the heat dissipation effect of intensive bus duct is improved significantly, the mechanical strength is guaranteed, the dust is prevented from entering, the system reliability and energy utilization efficiency are improved, and have significant technical advantage and positive effect.
