Description

Technical Field

[0001] The utility model relates to the field of electrical accessories, in particular to a busbar support structure for a low-voltage power distribution cabinet. Background Art

[0002] The busbar is an important component in the power distribution cabinet, which is mainly used for transmitting and distributing electric energy. In the power distribution cabinet, the busbar, as the main conductor, connects generators, transformers, circuit breakers and other electrical equipment to ensure that electric energy can effectively flow to each electrical load. The busbar is usually made of copper or aluminum materials with high conductivity to reduce energy loss. In different power distribution systems, the busbar can be of different types such as rigid busbar, flexible busbar or enclosed busbar to adapt to different electrical and environmental requirements.

[0003] When installing the busbar in the power distribution cabinet, in order to ensure the stability of the busbar and facilitate future maintenance, busbar brackets are usually installed in the power distribution cabinet by bolting or welding first, and then the busbar is fixed on the busbar brackets. However, this way of fixing the busbar brackets is relatively time-consuming, and it is a bit restricted to perform this operation in a power distribution cabinet with relatively limited internal space.

[0004] Therefore, aiming at the situation that in a power distribution cabinet with relatively limited internal space, installing busbar brackets by bolting or welding is relatively time-consuming and inconvenient, a busbar support structure for a low-voltage power distribution cabinet can be designed to solve the above problems. Summary of the Utility Model

[0005] In order to overcome the problem that when installing the busbar in the power distribution cabinet, in order to ensure the stability of the busbar and facilitate future maintenance, busbar brackets are usually installed in the power distribution cabinet by bolting or welding first, and then the busbar is fixed on the busbar brackets, but this operation is relatively time-consuming and inconvenient in a power distribution cabinet with relatively limited internal space.

[0006] The technical solution of the utility model is: a busbar support structure for a low-voltage power distribution cabinet, which includes an outer frame, an insertion fixing component and a heat dissipation component; insertion fixing components are fixedly connected to the rear ends of both sides of the outer frame; the insertion fixing component includes a front clamping strip; insertion strips are fixedly connected to both sides of the rear end face of the outer frame; accommodation grooves are respectively formed in the insertion strips; outer elastic strips are respectively accommodated in the accommodation grooves; hairspring springs are installed at both the upper and lower ends of the outer elastic strips; sliding insertion sleeves are respectively slidably connected to the outer sides of the insertion strips; a heat dissipation component is arranged between the two insertion strips; the heat dissipation component includes an air duct; five heat dissipation fins are fixedly connected in the air duct; two fans are installed at the bottom end of the air duct.

[0007] Preferably, before using this device, it is necessary to ensure that the rear end face of the power distribution cabinet is provided with a socket that can just accommodate the insertion strip and the air duct. Then, align the insertion strip and the air duct with their respective sockets and insert them into the sockets. After the insertion strip passes through the socket and penetrates the rear end of the power distribution cabinet, the clockwork spring causes the outer elastic strip to pop out of the accommodation groove, so as to hook this device from the outside of the power distribution cabinet through the outer elastic strip to prevent the device from falling off. Then, insert the sliding insertion sleeve on the outside of the insertion strip and the outer elastic strip to lock the insertion strip and the outer elastic strip through the sliding insertion sleeve, and clamp the cabinet body of the power distribution cabinet through the sliding insertion sleeve and the front clamping strip to improve the stability of the device, thereby realizing the rapid installation of the bus support.

[0008] Preferably, two buckles are installed on one side of the outer frame; cushion blocks are fixedly connected to the lower sides of the rear ends of the insertion strips. When the power distribution cabinet is working, the heat generated on the bus will be sequentially transferred to the partition board, the outer frame and the heat dissipation fins, and the heat on the heat dissipation fins will be blown away by the fan and taken out of the power distribution cabinet. Because in this process, the heat absorption area and the heat dissipation area of the bus support are both greatly increased, thus greatly increasing the heat dissipation efficiency of the device for the bus.

[0009] Preferably, the front end of the outer frame is rotatably connected to a cover plate through a hinge, and the hinge is located on the other side of the outer frame.

[0010] Preferably, two anchor hooks are fixedly connected to one side of the cover plate; three partition boards are fixedly connected to the inside of the outer frame.

[0011] Preferably, positioning strips fixedly connected to the rear end face of the cover plate are arranged on both sides of the front end of the partition board; sliding slots are opened in the sliding insertion sleeves. After placing the buses between the partition boards in the outer frame respectively and then closing the cover plate, and locking the cover plate through the anchor hooks and the buckles, the neatly arranged buses can be prevented from loosening, which is convenient for future maintenance.

[0012] Preferably, the insertion strip is rotatably connected to the outer elastic strip; one end of the clockwork spring contacts the insertion strip, and the other end contacts the outer elastic strip.

[0013] Preferably, the air duct is fixedly connected to the rear end face of the outer frame; the cushion blocks are all slidably connected to the lower ends of the sliding insertion sleeves.

[0016] 2. Before using this device, it is necessary to ensure that the rear end face of the power distribution cabinet is provided with a socket that can just accommodate the insertion strip and the air duct. Then, align the insertion strip and the air duct with their respective sockets and insert them. After the insertion strip passes through the socket and penetrates the rear end of the power distribution cabinet, the clockwork spring causes the outer elastic strip to pop out of the accommodation groove, so as to hook this device from the outside of the power distribution cabinet through the outer elastic strip to prevent the device from falling off. Then, insert the sliding insertion sleeve on the outside of the insertion strip and the outer elastic strip to lock the insertion strip and the outer elastic strip through the sliding insertion sleeve, and clamp the cabinet body of the power distribution cabinet through the sliding insertion sleeve and the front clamping strip to improve the stability of the device, thus realizing the rapid installation of the bus support;
