Description

Technical Field

[0001] The utility model relates to the technical field of copper bars, in particular to a heat-resistant copper bar. Background Technique

[0002] The copper bar, also known as copper busbar or copper busbar, is a large-current conductive product, which is suitable for electrical engineering such as high- and low-voltage electrical appliances, switch contacts, power distribution equipment, bus ducts, etc., and is also widely used in large-current electrolytic smelting projects such as metal smelting, electroplating, and chemical caustic soda. Generally, the A, B, C, and N-phase busbars and the PE busbar in the power distribution cabinet are all made of copper bars. Most of the copper bars are processed by punching, tin plating, etc. and put into use;

[0003] When the existing copper bars are installed, they are generally exposed in the electric cabinet. During the conduction process, the copper bars themselves will generate heat and have a certain heat resistance. Since the temperature generated by other components in the electric cabinet will cause the temperature in the vicinity to rise, plus the temperature of the copper bars themselves, it will cause the temperature and heat of the copper bars to increase rapidly. The existing copper bars usually achieve heat dissipation through the self-heat dissipation effect of the body during use, but the heat dissipation effect is slow. When the copper bars and the electrical components in the electric cabinet dissipate heat at the same time, the heat in the electric cabinet will make the copper bars in a high-temperature environment, thereby inhibiting the heat dissipation of the copper bars, resulting in poor heat resistance of the copper bars and affecting the transmission effect. For this reason, we propose a heat-resistant copper bar. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a heat-resistant copper bar, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A heat-resistant copper bar, including a copper bar body and a protective shell. A clamping groove is opened at the bottom end of the inner cavity of the protective shell, and the copper bar body is detachably connected to the inner cavity of the clamping groove. An inner frame is arranged on the inner side of the protective shell, and the bottom edge of the inner frame is fixedly connected to the bottom wall of the inner side of the protective shell. An insulating cavity is opened on the inner side of the protective shell, and the insulating cavity is located outside the inner frame. On both sides of the upper end of one side of the protective shell, a first ventilation component and a second ventilation component are respectively connected forward, and the first ventilation component is communicated with the inner frame, and the second ventilation component is communicated with the insulating cavity. On both sides of the upper end of the side of the protective shell corresponding to the first ventilation component and the second ventilation component, corresponding exhaust pipes are inlaid and connected.

[0006] Preferably, both the first ventilation component and the second ventilation component include a ventilation pipe. A limiting edge is fixedly connected to the air outlet end of the inner cavity of the ventilation pipe. A dust filter plate is arranged on the surface of the limiting edge. Connecting threads are opened on the inner surface of the air outlet end of the ventilation pipe.

[0007] Preferably, a connector is detachably connected to the air outlet end of the ventilation pipe. An internally threaded pipe adapted to the connection thread is fixedly connected to the inner side wall of the connector, and an externally threaded pipe is fixedly connected to the outer side wall of the connector.

[0008] Preferably, a bottom plate is detachably provided at the bottom end of the protective shell.

[0009] Preferably, fastening bolts are threadedly connected to the four corners around the top end of the protective shell, and the fastening bolts vertically penetrate through the protective shell and extend into the interior of the bottom plate.

[0010] Preferably, connection holes are formed in the upper surfaces on both sides of the copper bar body, and the connection holes penetrate through the copper bar and extend to the bottom end of the copper bar.

[0011] Preferably, the protective shell and the inner frame are of an integral structure.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the mutual cooperation of the protective frame, inner frame, heat insulation cavity, ventilation pipe, connector and exhaust pipe, when using the copper bar provided in the embodiment, the ventilation pipe is connected to an external air source by means of the connector, and then the air inlet connector is communicated with the external air source. The external air source is used to drive the air flow, so that the air flow flows in the heat insulation cavity and the inner cavity of the inner frame, and flows out of the protective frame through the exhaust pipe. This can not only discharge the heat generated by the copper bar in the inner frame, improve the heat dissipation effect of the copper bar, but also block the external heat from being conducted into the protective frame through the heat insulation cavity. The heat conducted into the interior of the heat insulation cavity is discharged through the exhaust air channel formed by the second ventilation component and the heat insulation cavity, effectively ensuring the heat insulation effect and improving the heat resistance of the copper bar, so as to ensure a good transmission effect during use.

[0014] 2. Through the mutual cooperation of the ventilation pipe, limiting edge, connection thread, dust filter plate, connector, internally threaded pipe and externally threaded pipe, the dust filter plate is clamped at the air inlet of the inner cavity of the ventilation pipe by means of the limiting plate. During the ventilation process, the dust filter plate can filter the dust in the air, avoiding dust entering the interior of the protective shell and adhering to the surface of the copper bar during the heat dissipation process, which affects the transmission effect and heat dissipation effect during its use. Moreover, the ventilation pipe is connected to the internally threaded pipe opened on the inner side of the connector through the connection thread opened on the outer surface of the outer end inner cavity, making it convenient and quick to disassemble the ventilation pipe and the connector. This facilitates the cleaning of the dust filter plate in the later stage, ensures the filtering effect while also ensuring the ventilation effect, effectively improves the service life and heat resistance of the copper bar, and ensures the transmission effect during use.

The external air source is used to drive the air flow, so that the air flow flows in the inner cavities of the heat insulation cavity 9 and the inner frame 11, and flows out of the protective frame through the exhaust pipe 10. This can not only discharge the heat generated by the copper bar in the inner frame 11 and improve the heat dissipation effect of the copper bar, but also block the external heat from being conducted into the protective frame through the heat insulation cavity 9, and the heat conducted into the inner part of the heat insulation cavity 9 is discharged through the exhaust air channel formed by the second ventilation component 8 and the heat insulation cavity 9, effectively ensuring the heat insulation effect and improving the heat resistance of the copper bar.

[0022] Among them, both the first ventilation component 7 and the second ventilation component 8 include a ventilation pipe 701.

A connecting thread 703 is provided on the inner cavity surface of the air outlet end of the ventilation pipe 701. The dust filter plate 704 is clamped at the air inlet of the inner cavity of the ventilation pipe 701 by means of a limiting plate. During the ventilation process, the dust filter plate 704 can filter the dust in the air, preventing the dust from entering the inside of the protective shell 1 during heat dissipation and adhering to the surface of the copper busbar, thus affecting its transmission effect and heat dissipation effect during use.

The integral design can ensure the sealing performance during use, thereby effectively conducting ventilation and heat dissipation, and thus improving the heat resistance of the copper busbar body 4.

[0026] It should be noted that the present utility model is a heat-resistant copper bar. The protective shell 1 is snap-fitted on the surface of the copper bar body 4 through the snap-fitting groove 6 opened at the bottom end, so as to cover the copper bar body 4 inside, and the base is snap-fitted to the bottom end of the protective shell 1 from the bottom, and the two are fixed by means of the fastening bolt 3, so as to stably fix the copper bar body 4 in the protective shell 1.
