Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a high and low voltage power distribution cabinet with good heat dissipation function. Background Technology

[0002] High and low voltage switchgear, as the name suggests, are power distribution equipment used in power supply systems for power distribution, control, metering, and cable connection. Power supply bureaus and substations generally use high voltage switchgear.

[0003] However, existing high and low voltage switchgear has certain shortcomings in use. Currently, it simply relies on ventilation holes for heat dissipation, which is inefficient. Overheating of internal electrical components can damage them and even cause fires, making its heat dissipation practically ineffective. Some switchgear uses fans for cooling, with dust filters at the air inlets; however, rainwater can easily seep through these filters and damage the internal components.

[0004] Chinese Utility Model Patent Publication No. CN 222508544 U discloses a high- and low-voltage distribution cabinet with good heat dissipation function. This high- and low-voltage distribution cabinet with good heat dissipation function can effectively dissipate heat from the inside of the distribution cabinet through a fan, and has the effect of dustproofing and rainproofing, preventing rainwater from entering the distribution cabinet and damaging the electrical components. In addition, it also facilitates the disassembly and cleaning of the filter plate. When the high- and low-voltage distribution cabinet with good heat dissipation function does not have a heat dissipation structure and only relies on a fan to dissipate heat from the inside of the distribution cabinet, the heat dissipation efficiency is low. When the distribution cabinet is under load, if the heat inside the distribution cabinet cannot be dissipated in time, it will cause damage to electronic components, resulting in low practicality. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a high and low voltage distribution cabinet with good heat dissipation function, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: a high and low voltage power distribution cabinet with good heat dissipation function, including a cabinet and a cabinet door. A first heat dissipation component is inserted and installed in the center of the cabinet door at the end away from the cabinet. A positioning post is provided at the end of the cabinet door close to the cabinet. Through holes are opened on both sides of the cabinet door. A groove is opened at the bottom of the end of the cabinet close to the cabinet door. A second heat dissipation component is provided inside the through hole. A support component is provided inside the groove.

[0007] The first heat dissipation component includes a mounting plate, and the end of the mounting plate near the cabinet is fixedly equipped with mounting holes that align with the positioning posts.

[0008] The second heat dissipation component includes a connecting plate that is plugged into a through hole, and the connecting plate is fixed to the outside of the cabinet by fixing screws.

[0009] Preferably, a handle is provided at the end of the cabinet door away from the cabinet, a handwheel is provided on the side of the positioning post away from the cabinet door and threadedly connected to the positioning post, and a grounding hole is provided at the bottom inner side of the cabinet.

[0010] The above technical solution allows for easy opening of the cabinet door by providing a handle. The threaded connection between the handwheel and the positioning post enables the first heat dissipation component to be quickly installed on the inside of the cabinet door via the guiding action of the positioning post. The worker then aligns the handwheel with the positioning post and rotates it until it is tightly fitted to the first heat dissipation component, thus quickly fixing it in place without the need for other tools, thereby improving installation efficiency.

[0011] Preferably, the first heat dissipation component further includes a mounting slot, a fixing plate, heat dissipation fins, a first cooling fan, a fan housing, a first dustproof plate, and a moisture-proof drying cotton. The mounting plate has a mounting slot at one end near the cabinet, and a fixing plate is fixedly installed on the inner side of the mounting slot. The fixing plate has heat dissipation fins at one end near the cabinet, and a first cooling fan and a fan housing at one end away from the cabinet. The mounting plate has a first dustproof plate and a moisture-proof drying cotton on the side away from the fixing plate.

[0012] The above technical solution increases the heat dissipation area inside the cabinet by setting heat dissipation fins. Then, the heat dissipation fan will expel the heat in time, keeping the inside of the cabinet at a low temperature. In addition, the dustproof plate can effectively prevent dust, oil mist, moisture and corrosive gases in the ambient air from entering the cabinet, reducing electrical failures.

[0013] Preferably, the second heat dissipation component further includes an air outlet, a slot, a screw hole, a second cooling fan, a knob, a second dustproof plate, and a plug. The connecting plate has an air outlet on its inner side near the cabinet, a slot and a screw hole on its side away from the cabinet, a second cooling fan fixedly installed on its side away from the cabinet, a knob between the two sets of slots on the connecting plate, a second dustproof plate on its side away from the cabinet, and a plug for insertion into the slot fixedly installed on its side near the connecting plate.

[0014] The above technical solution facilitates the quick installation of the dustproof plate and the connecting plate by setting the plug and slot connection. By rotating the knob, the dustproof plate is engaged with the connecting plate, preventing it from falling off. The detachable design of the dustproof plate and the connecting plate makes it easy for staff to clean the dustproof plate later, preventing excessive dust from affecting heat dissipation efficiency.

[0015] Preferably, the support assembly includes a fixed base, a support arm, a rotating shaft, and a support foot. The fixed base is fixedly installed on the inner side of the groove, the support arm is provided on the inner side of the fixed base, and the rotating shaft, which is rotatably connected to the support arm, is also provided on the inner side of the fixed base. The support foot is threadedly installed on the end of the support arm away from the fixed base.

[0016] The above technical solution incorporates a support assembly. When the distribution cabinet is installed, rotating the support arm adjusts the contact height between the support feet and the ground, effectively improving the stability of the distribution cabinet.

[0017] Preferably, the thickness of the support arm is less than the thickness of the groove, and the support arm can be retracted into the groove.

[0018] With the above technical solution, when the working environment is stable, the staff can store the outrigger inside the groove, saving space.

[0019] Preferably, the second heat dissipation component is provided in two identical sets, and the two sets of the second heat dissipation components are symmetrically distributed on the outside of the cabinet.

[0020] The above technical solution facilitates the rapid dissipation of heat from inside the cabinet by setting up two identical second heat dissipation components, thereby reducing the risk of electronic components being damaged due to high temperatures.

[0021] Compared with the prior art, this utility model provides a high and low voltage distribution cabinet with good heat dissipation function, which has the following beneficial effects:

[0022] 1. This high and low voltage distribution cabinet with excellent heat dissipation function is first installed by plugging the first heat dissipation component into the cabinet door. The mounting plate is then installed on the inside of the cabinet door, where the positioning post is inserted into the mounting hole. The operator then aligns the handwheel with the positioning post and rotates the handwheel until it is tightly fitted with the first heat dissipation component, thus quickly fixing the first heat dissipation component without the need for other tools, thereby improving installation efficiency. The detachable design of the first heat dissipation component facilitates cleaning and maintenance, greatly improving work efficiency. The heat dissipation fins effectively increase the heat exchange area with the inside of the cabinet. The cooling fan then promptly dissipates heat, keeping the inside of the cabinet at a low temperature. The dustproof plate effectively prevents dust, oil mist, moisture, and corrosive gases from entering the cabinet, reducing electrical faults. The two sets of second heat dissipation components further improve the heat dissipation effect of the distribution cabinet, reducing the risk of electrical damage caused by excessively high internal electrical temperatures.

[0023] 2. This high and low voltage distribution cabinet with good heat dissipation can effectively improve the stability of the distribution cabinet by rotating the support arm and adjusting the contact height between the support foot and the ground after the distribution cabinet is installed. When the working environment of the distribution cabinet is stable, the staff can also put the support arm into the groove, saving space. Attached Figure Description

Then, the staff aligns the handwheel 6 with the positioning post 5 and rotates it until it is tightly fitted with the first heat dissipation component 3, thus quickly fixing the first heat dissipation component 3 without the need for other tools, thereby improving installation efficiency.

[0038] Specifically, the first heat dissipation component 3 also includes a mounting slot 303, a fixing plate 304, heat dissipation fins 305, a cooling fan 306, a fan housing 307, a dustproof plate 308, and a moisture-proof drying cotton 309.

[0044] Working Principle: In use, the first heat dissipation component 3 is first installed by plugging it into the cabinet door 2. The mounting plate 301 is then installed inside the cabinet door 2. At this point, the positioning post 5 can be inserted into the mounting hole 302. Then, the operator aligns the handwheel 6 with the positioning post 5 and rotates the handwheel 6 until it is tightly fitted with the first heat dissipation component 3, thus quickly fixing the first heat dissipation component 3. No other tools are needed for fixing, improving installation efficiency. The detachable design of the first heat dissipation component 3 facilitates cleaning and maintenance, greatly improving work efficiency. The heat dissipation fins 305 effectively increase the heat exchange area with the inside of the cabinet 1. The cooling fan 306 then promptly dissipates heat, keeping the inside of the cabinet 1 at a low temperature. The dustproof plate 308 effectively prevents dust, oil mist, moisture, and corrosive gases from entering the cabinet 1, reducing electrical faults. Finally, the connecting plate 901... The insertion and installation of the through hole 7 facilitates the quick and easy positioning and installation of the second heat dissipation component 9 on the outside of the cabinet 1. Subsequently, the insertion and installation of the plug 908 and the slot 903 facilitates the quick installation of the dustproof plate 907 and the connecting plate 901.

By setting two sets of identical second heat dissipation components 9, the heat dissipation effect of the power distribution cabinet is further improved. A support component 10 is set up. When the power distribution cabinet is installed, by rotating the support arm 1002, the contact height between the support foot 1004 and the ground is adjusted, which effectively improves the stability of the power distribution cabinet. When the working environment of the power distribution cabinet is stable, the staff can also store the support arm 1002 into the groove 8, saving space.
