Description

Technical Field

[0001] The present invention relates to the technical field of power distribution, and in particular to a three-phase high-power intelligent power distribution device. Background Art

[0002] A PDU (Power Distribution Unit), that is, the power distribution socket commonly used in cabinets, is a product designed to provide power distribution for electrical equipment installed in cabinets, and can provide a suitable rack-mounted power distribution solution for different power environments.

[0003] In current intelligent PDU power distributors, most of the internal circuit boards and sockets are connected by soldering with flexible wires. The wire lengths are different and the bending degrees are inconsistent. The wires are messy inside. When the power distributor is installed in a cabinet and a computer room, it will occupy too much of its effective space, reducing the volume ratio of the cabinet and the computer room, and having a low power consumption density. Moreover, most of the PDU products on the current market lack an efficient heat dissipation structure design. Usually, they rely on their own heat conduction mechanism to gradually transfer the internal heat to the external air for heat dissipation. Among them, due to a large number of wirings needed to be connected on the busbar copper row, there are certain resistances in the wires, connectors and contacts inside the PDU socket, resulting in the PDU socket heating up, leading to too high ambient temperature and poor heat dissipation. This current situation not only affects the performance of the PDU device, but also may bring potential risks to its long-term stable operation. Therefore, improving the heat dissipation efficiency of the PDU has become an urgent problem to be solved.

[0004] Therefore, we make improvements on this and propose a three-phase high-power intelligent power distribution device. Summary of the Invention

[0005] The purpose of the present invention is to provide a three-phase high-power intelligent power distribution device to solve the problems raised in the above background art.

[0006] To achieve the above invention purpose, the present invention provides a three-phase high-power intelligent power distribution device, including a housing. A universal fixing frame is fixedly connected to the rear end of the housing. A plurality of independent pluggable modules are arranged at the front end of the universal fixing frame. Hinges are installed at the upper ends of the housing and the pluggable modules. A plurality of the pluggable modules are arranged side by side on one side of the housing. A main switch and a junction box are installed in the middle of the housing. A busbar copper row is connected in the middle of the housing. The busbar copper row is fixedly installed on the front side of the universal fixing frame. An installation bracket is fixedly connected to the upper end of the universal fixing frame. The front end of the installation bracket presses on the upper end surface of the pluggable module. An intake fan is installed on the rear side surface of the universal fixing frame.

[0007] As a further solution of the present invention, the pluggable module includes a housing. A wire threading hole is formed in the middle of the back of the housing. A pluggable frame is slidably connected inside the housing. A plugging and unplugging component is installed at the rear end of the pluggable frame. The plugging and unplugging component is plugged and installed on the housing, and the plugging and unplugging component penetrates through the wire threading hole and is electrically connected to the busbar copper row. A connecting plate is installed at the upper end inside the housing. A bent plate is connected to the rear end of the connecting plate. An air duct is connected to the outer end of the bent plate. The air duct is fixedly connected to the universal fixing frame. An exhaust fan is arranged at the bottom end of the housing.

[0008] As a further solution of the present invention, the connecting plate is fixedly installed on the top surface of the housing, and a plurality of arc-shaped air guiding plates are connected to the bottom surface of the connecting plate.

[0009] As a further solution of the present invention, the universal fixing frame includes a gas collecting cavity, and a mounting buckle plate is movably installed on the back of the gas collecting cavity.

[0010] As a further solution of the present invention, the mounting bracket includes a fixing plate. The fixing plate straddles the upper ends of the housing and the universal fixing frame. Hanging plates are fixedly connected to both ends of the fixing plate. A plurality of clamping holes are formed in the middle of the fixing plate. A clamping block is sleeved inside the clamping hole. The clamping block is bolted to the universal fixing frame. A push-pull plate is slidably sleeved on the upper end of the clamping block. The front end of the push-pull plate presses on the top surface of the pluggable module.

[0011] As a further solution of the present invention, insulating baffles are installed at both ends of the interlayer between the universal fixing frame and the pluggable module.

[0012] As a further solution of the present invention, the air duct is a soft insulating leather ventilation pipe.

[0013] As a further solution of the present invention, when the push-pull plate is pushed away from the top surface of the pluggable module, the pluggable module is turned up, so as to repair and inspect the wire part between the pluggable module and the universal fixing frame. A circuit breaker and a leakage protector are installed on the pluggable module.

[0014] For the three-phase high-power intelligent power distribution device provided by the present invention, the beneficial effects are as follows: 1. By providing a space for storing a plurality of pluggable modules on one side of the housing and the universal fixing frame, and hinging the plurality of pluggable modules to the universal fixing frame, the pluggable modules can be flipped along the hinge at the front end of the universal fixing frame. When flipped, the wiring part between the pluggable module and the busbar copper row is exposed, which is convenient for performing convenient and rapid repair operations on the wiring position of the busbar copper row, increasing the convenience of the device during wiring and repair. There is no need to open the rear cover, and the pluggable module can be tightly fixed through the individual mounting brackets on each pluggable module.

[0015] 2. By installing the busbar copper row in the sandwich space between the universal fixing frame and the pluggable module, and providing protective plates with ventilation grids on both sides of the sandwich of the pluggable module and the universal fixing frame, the busbar copper row is separated from the internal components of the pluggable module, which not only facilitates the operation and treatment of the wiring on the busbar copper row, but also enables independent ventilation and heat dissipation of the busbar copper row, avoiding the accumulation of a large amount of heat on the busbar copper row and affecting other components inside the pluggable module.

[0016] 3. By installing an intake fan inside the universal fixing frame, connecting the pluggable module and the universal fixing frame through an air duct, installing a connecting plate and a wind guiding plate inside the pluggable module, the air flow inside the universal fixing frame is evenly blown into the interior of the housing through the air duct and the wind guiding plate, for uniform heat dissipation inside the housing. An exhaust fan is installed at the bottom of the housing, and the hot air inside the housing is blown out through the exhaust fan, so that the intake and exhaust ports of the pluggable module are staggered, avoiding the re - circulation of hot air into the interior of the pluggable module and facilitating the overall heat dissipation of the pluggable module.

[0020] The following will further describe in detail the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification and embodiments. The following embodiments are only used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] As Figures 1-10 shown, this embodiment proposes a three-phase high-power intelligent power distribution device, including a housing 1. A universal fixing frame 5 is fixedly connected to the rear end of the housing 1. A plurality of independent pluggable modules 4 are arranged at the front end of the universal fixing frame 5. A hinge 9 is installed at the upper ends of the housing 1 and the pluggable modules 4. A plurality of pluggable modules 4 are arranged side by side on one side of the housing 1. A main switch 2 and a junction box 3 are installed in the middle of the housing 1. A busbar 6 is connected in the middle of the housing 1. The busbar 6 is fixedly installed on the front side of the universal fixing frame 5. A mounting bracket 7 is fixedly connected to the upper end of the universal fixing frame 5. The front end of the mounting bracket 7 presses on the upper end surface of the pluggable module 4. An intake fan 8 is installed on the rear side surface of the universal fixing frame 5.

[0022] The pluggable module 4 includes a housing 41. A wire threading hole 46 is formed in the middle of the back of the housing 41. A pluggable frame 42 is slidably connected inside the housing 41. A plugging and unplugging component 44 is installed at the rear end of the pluggable frame 42. The plugging and unplugging component 44 is plugged and installed on the housing 41, and the plugging and unplugging component 44 penetrates through the wire threading hole 46 and is electrically connected to the busbar copper row 6. A connecting plate 43 is installed at the upper end inside the housing 41. The rear end of the connecting plate 43 is connected to a bent plate 47. The outer end of the bent plate 47 is connected to an air duct 48. The air duct 48 is fixedly connected to the universal fixing frame 5. An exhaust fan 45 is arranged at the bottom end of the housing 41. The pluggable module 4 is an integrated pluggable power module. After the busbar copper row 6 is electrically connected to the plugging and unplugging component 44, it can be hot-plugged with the pluggable frame 42, which is convenient for quick assembly and use of the device, and can be matched with sockets of different specifications.

[0023] The connecting plate 43 is fixedly installed on the top surface of the housing 41, and a plurality of arc-shaped air guiding plates 49 are connected to the bottom surface of the connecting plate 43. The air guiding plates 49 are installed in a staggered manner like fish scales on the bottom surface of the connecting plate 43 and are bent downward, so that the gas introduced through the air duct 48 is evenly dispersed into the housing 41 through the air guiding plates 49, and the inside of the housing 41 is evenly cooled, avoiding device damage caused by insufficient heat dissipation in the blind area inside the housing 41.

[0024] The universal fixing frame 5 includes an air collecting cavity 51. An installation buckle plate 52 is movably installed on the back of the air collecting cavity 51. An intake fan 8 is installed inside the air collecting cavity 51 and the installation buckle plate 52. The intake fan 8 introduces gas into the universal fixing frame 5, and then enters the pluggable module 4 through the air duct 48 connected to the universal fixing frame 5 to cool the pluggable module 4. The busbar copper row 6 is installed on the universal fixing frame 5, which not only fixes the busbar copper row 6 but also improves the heat dissipation efficiency of the busbar copper row 6.

[0025] The mounting bracket 7 includes a fixing plate 71 which straddles the upper ends of the housing 1 and the general fixing frame 5. Both ends of the fixing plate 71 are fixedly connected with hanging plates 72. A plurality of bayonets 73 are formed in the middle of the fixing plate 71. A clamping block 74 is sleeved inside the bayonet 73. The clamping block 74 is bolted to the general fixing frame 5. A push-pull plate 75 is slidably sleeved on the upper end of the clamping block 74. The front end of the push-pull plate 75 presses on the top surface of the pluggable module 4. The mounting bracket 7 is located at the upper end of the general fixing frame 5, fixing the housing 1 and the general fixing frame 5 inside a container or other electrical equipment. Moreover, the front end of the push-pull plate 75 slidably connected through the clamping block 74 on the fixing plate 71 presses tightly on the pluggable module 4, preventing the pluggable module 4 from flipping upwards and separating from the general fixing frame 5, ensuring the stable connection between the pluggable module 4 and the general fixing frame 5. When the push-pull plate 75 is pushed backward, the push-pull plate 75 separates from the pluggable module 4, canceling the limit above the pluggable module 4. By flipping the pluggable module 4 upwards, operations can be carried out on the sandwich space between the pluggable module 4 and the general fixing frame 5, making the wiring positions behind each pluggable module 4 clearer and more distinct, facilitating operation.

[0026] Insulating baffles are installed at both ends of the sandwich between the general fixing frame 5 and the pluggable module 4. The insulating baffles are provided with ventilated grids, which can not only protect both ends of the sandwich between the pluggable module 4 and the general fixing frame 5, but also prevent heat from accumulating and being unable to escape, enabling the busbar copper row 6 to work stably and safely in the sandwich.

[0027] The air duct 48 is a flexible insulating leather ventilation pipe. The air duct 48 deforms as the outer shell 41 flips, introducing the gas in the general fixing frame 5 into the pluggable module 4 to cool and dissipate heat from the pluggable module 4. The push-pull plate 75 is pushed away from the top surface of the pluggable module 4, and the pluggable module 4 is flipped upwards to repair and inspect the wire part between the pluggable module 4 and the general fixing frame 5. A circuit breaker and a leakage protector are installed on the pluggable module 4.

[0028] Specifically, when the three-phase high-power intelligent power distribution device is in use: A plurality of pluggable modules 4 are hinged on one side of the housing 1 and the general fixing frame 5. The individual mounting brackets 7 on each pluggable module 4 can fix the pluggable module 4 tightly. The front end of the push-pull plate 75 slidably connected to the fixing plate 71 by the clamping block 74 presses tightly on the pluggable module 4, preventing the pluggable module 4 from flipping upward and separating from the general fixing frame 5, ensuring the stable connection between the pluggable module 4 and the general fixing frame 5. When the push-pull plate 75 is pushed backward, the push-pull plate 75 separates from the pluggable module 4, canceling the limit above the pluggable module 4. By flipping the pluggable module 4 upward, operations can be performed on the sandwich space between the pluggable module 4 and the general fixing frame 5, making the wiring positions behind each pluggable module 4 clearer and exposing the wiring part between the pluggable module 4 and the busbar copper row 6, facilitating convenient and quick maintenance operations on the wiring position of the busbar copper row 6, increasing the convenience during wiring and maintenance of the device without opening the rear cover. The busbar copper row 6 is independently installed in the sandwich space between the general fixing frame 5 and the pluggable module 4, facilitating the handling of the wiring on the busbar copper row 6 and enhancing the ventilation and heat dissipation effect of the busbar copper row 6, preventing a large amount of heat from accumulating on the busbar copper row 6 and affecting other components inside the pluggable module 4. An intake fan 8 is installed inside the general fixing frame 5, and the pluggable module 4 and the general fixing frame 5 are connected by an air duct 48. A connecting plate 43 and a wind guide plate 49 are installed inside the pluggable module 4, and the air flow inside the general fixing frame 5 is evenly blown into the interior of the housing 41 through the air duct 48 and the wind guide plate 49 for uniform heat dissipation of the interior of the housing 41. An exhaust fan 45 is installed at the bottom of the housing 41, and the hot air inside the housing 41 is blown out through the exhaust fan 45, staggering the intake and exhaust ports of the pluggable module 4 to prevent the hot air from recirculating into the interior of the pluggable module 4, facilitating the overall heat dissipation of the pluggable module 4. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0029] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications, or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered within the scope of the claims of the present invention.
