Description

Technical Field

[0001] The utility model is a high-current-carrying fireproof busbar which can be used in a computing center. Background Art

[0002] Busbar ducts, enclosed metal structures composed of copper and aluminum busbars, are used to distribute high power to various components in distributed systems. They are increasingly replacing wires and cables in indoor low-voltage power transmission trunk projects. They are common in developed countries, as well as in Hong Kong and Macau. In Guangzhou, Guangdong, my country, over 90% of the main lines from distribution rooms in buildings with 12 floors or more, or those leading to the floors, use busbar ducts. Busbar ducts are also required for connections from 630 kVA transformers to distribution cabinets.

[0003] However, due to the closed internal structure of the bus duct, the temperature inside is easily increased, which may cause a fire. Therefore, the heat dissipation problem inside the bus duct has always been a concern. There are currently many ways to achieve this goal in the market. This patent will propose a new structure to meet the heat dissipation needs of the bus duct. Utility Model Content

[0004] The purpose of the utility model is to solve the above deficiencies in the prior art and to provide a high current carrying fireproof busbar that can be used in a computing center.

[0005] A high-current-carrying fireproof busbar that can be used in a computing center includes a housing and a conductive busbar. The housing is a split structure and includes a U-shaped bottom shell and a U-shaped cover plate. The conductive busbar is installed in the bottom shell. The upper end surface of the cover plate is provided with a first ventilation hole, and mounting holes are provided on both sides of the first ventilation hole.

[0006] A movable baffle is provided at the first ventilation hole, and the movable baffle includes an upper baffle and a lower baffle. The upper baffle and the lower baffle are connected by two connecting columns. The two connecting columns are movably inserted into the mounting hole. The upper baffle is located above the cover plate, and the lower baffle is located below the cover plate.

[0007] The upper baffle and the lower baffle are provided with threaded holes for installing connecting columns. A spring is sleeved on the outside of the connecting column. One end of the spring is against the upper end surface of the pad, and the other end of the spring is against the lower end surface of the cover. The pad is sleeved on the outside of the connecting column and is located above the lower baffle.

[0008] Preferably, the conductive bar includes a plurality of guide plates arranged in parallel at intervals, and the guide plates are arranged along the length direction of the bottom shell and extend from the front port and the rear port of the shell.

[0009] Preferably, the guide plate is made of copper.

[0010] Preferably, the outer side of the guide plate comprises insulating material.

[0011] Preferably, the insulating material is mica sheet.

[0012] Preferably, the conductive bar is fixed to the bottom shell by a fixing structure, and the fixing structure includes a lower clamping plate and an upper clamping plate. The upper end surface of the lower clamping plate is provided with a plurality of first through slots, and the lower end surface of the upper clamping plate is provided with a plurality of second through slots. The first through slots and the second through slots are used to fix the guide plate. The lower clamping plate is clamped at the bottom of the guide plate, and the upper clamping plate is clamped at the top of the guide plate. The bottom of the lower clamping plate is fixedly connected to the bottom surface of the bottom shell, and the upper clamping plate and the lower clamping plate are connected in sequence by bolts.

[0013] Preferably, a plurality of second ventilation holes are provided on the surface of the bottom shell.

[0014] Preferably, a filter is provided in the second ventilation hole.

[0015] Preferably, a platform is provided inside the bottom shell, and the platform is used to support the lower baffle, and the lower end surface of the lower baffle is connected to the upper end surface of the platform.

[0016] Preferably, the platform includes two bearing plates arranged on the inner side surfaces of the side plates of the bottom shell, and the bearing plates are perpendicular to the side plates of the bottom shell and are arranged along the length direction of the bottom shell.

[0017] Beneficial effect: Compared with the prior art, the present invention controls the opening and closing of the first ventilation hole through the movable baffle. When the temperature inside the bus duct rises, the internal air pressure will also increase. When the air pressure reaches a certain level, the movable baffle will be pushed up, so that the upper baffle will leave the ventilation port and the lower baffle will leave the bearing plate, so that the air inside the bus duct and the external air can exchange heat through the first through-hole, thereby achieving the purpose of heat dissipation. When the inside of the bus duct is not overheated, the upper baffle covers the top of the first ventilation hole, so that the first ventilation hole is closed to prevent foreign matter from entering. When the upper baffle rises and leaves the first ventilation hole port due to excessive air pressure inside the bus duct, the flow direction of the gas is from high pressure to low pressure, that is, from inside the bus duct to outside the bus duct, so that no foreign matter can enter through the first ventilation hole.

[0018] A spring is added between the lower baffle and the cover plate to prevent the shaking of the movable baffle when the bus duct vibrates, thereby reducing damage and noise. The elastic force of the spring is adjusted by increasing or decreasing the number of pads, thereby adjusting the pressure threshold for lifting the movable baffle, and at the same time preventing the lower baffle from fitting against the lower end surface of the cover plate and blocking the first ventilation hole.

[0029] A high-current-carrying fireproof busbar that can be used in a computing center includes a housing and a conductive busbar. The housing is a split structure and includes a U-shaped bottom shell 3 and a U-shaped cover plate 1. The conductive busbar is installed in the bottom shell 3. The upper end surface of the cover plate 1 is provided with a first ventilation hole 7, and mounting holes 8 are provided on both sides of the first ventilation hole 7.

[0030] The first ventilation hole 7 is provided with two movable baffles, which include an upper baffle 9 and a lower baffle 12. The upper baffle 9 and the lower baffle 12 are connected by two connecting columns 10. The two connecting columns 10 are movably provided in the mounting hole 8. The upper baffle 9 is located above the cover plate 1, and the lower baffle 12 is located below the cover plate 1.

[0031] Threaded holes for installing the connecting column 10 are provided on the upper baffle 9 and the lower baffle 12. A spring 11 is sleeved on the outside of the connecting column 10. One end of the spring 11 is against the upper end surface of the pad 14, and the other end of the spring 11 is against the lower end surface of the cover 1. The pad 14 is sleeved on the outside of the connecting column 10 and is located above the lower baffle 12.

[0032] A platform is provided inside the bottom shell 3, which is used to support the lower baffle 12. The lower end surface of the lower baffle 12 is connected to the upper end surface of the platform. The platform includes two supporting plates 13 arranged on the inner side surfaces of the side plates of the bottom shell 3. The supporting plates 13 are perpendicular to the side plates of the bottom shell 3 and are arranged along the length direction of the bottom shell 3.

[0033] The conductive bar includes a plurality of guide plates 4 arranged in parallel at intervals. The guide plates 4 are arranged along the length direction of the bottom shell 3 and extend from the front port and the rear port of the shell. The material of the guide plates 4 is copper, and the outer side of the guide plates 4 includes an insulating material, which is a mica sheet.

[0034] The conductive bar is fixed to the bottom shell 3 through a fixing structure, and the fixing structure includes a lower clamping plate 6 and an upper clamping plate 5. The upper end surface of the lower clamping plate 6 is provided with a plurality of first through grooves, and the lower end surface of the upper clamping plate 5 is provided with a plurality of second through grooves. The first through grooves and the second through grooves are used to fix the guide plate 4. The lower clamping plate 6 is clamped at the bottom of the guide plate 4, and the upper clamping plate 5 is clamped at the top of the guide plate 4. The bottom of the lower clamping plate 6 is fixedly connected to the bottom surface of the bottom shell 3, and the upper clamping plate 5 and the lower clamping plate 6 are connected in sequence by bolts.

[0035] A plurality of second ventilation holes are provided on the surface of the bottom shell 3 , and filters are provided in the second ventilation holes.

[0036] Instructions for use: When the bus duct is overheated, the lower baffle 12 of the movable baffle 2 is overlapped on the bearing platform. In actual operation, in order to prevent the lower baffle 12 from rubbing against the side plate of the bottom shell 3 when it moves and affecting its movement, a gap is left between the side surface of the lower baffle 12 and the inner side surface of the bottom shell 3. The existence of the gap can cause air leakage, resulting in insufficient gas pressure and affecting the lifting of the movable parts.

[0037] When the bus duct is overheated and the internal air pressure is too high, pressure is applied to the lower baffle 12, lifting the movable baffle 2 upward, so that the upper baffle 9 leaves the first ventilation hole 7 and the lower baffle 12 leaves the bearing plate 13, realizing air exchange between the inside and outside of the bus duct, thereby achieving the purpose of heat dissipation, and due to the existence of the lower baffle 12, it can prevent the movable components from detaching.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
