Description

Technical Field

[0001] The utility model relates to the technical field of power transmission and distribution equipment, in particular to a heat dissipation distribution box. Background Art

[0002] A power distribution cabinet is a comprehensive power distribution device that integrates electrical components, instruments, protective devices, and switchgear. It is primarily used to distribute, control, protect, and monitor electricity. It is widely used in industrial, commercial, and residential applications, providing a stable and secure power supply for various electrical equipment and systems. The design and construction of power distribution cabinets are carefully considered to ensure they can withstand various environmental conditions and operational requirements while ensuring operator safety.

[0003] A heat dissipation distribution box is a type of power distribution equipment that integrates a cooling fan. The importance of a heat dissipation distribution box is self-evident. During the operation of electrical equipment, components generate a certain amount of heat due to the thermal effects of the current. If this heat cannot be dissipated promptly, the equipment temperature will rise, affecting its performance and stability, and may even cause equipment failure or safety accidents. The use of a heat dissipation distribution box can effectively solve this problem, ensuring that electrical equipment maintains stable performance and safe operation during long-term operation. However, during live maintenance or live operation of the heat dissipation distribution box, the cooling fan continues to operate, and the airflow into the heat dissipation distribution box can blow towards the operator, especially when the operator is close to the eye, causing discomfort and affecting related operations. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a heat dissipation distribution box.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A heat dissipation distribution box comprises a box body, a box door hinged on the box body, a vent arranged on one side of the box body, and a heat dissipation fan arranged on the other side of the box body; a travel switch is fixedly connected to the box body, and the travel switch is connected in series with the power supply circuit of the heat dissipation fan; the travel switch comprises a shell and an operating head; the shell is fixedly connected to the box body; when the box door is closed, the operating head is pressed by the door body, causing the travel switch to be turned on.

[0007] Preferably, the shell is fixedly connected to the box body via a connecting seat.

[0008] Preferably, one end of the heat dissipation fan outside the box is fixedly connected to an insect-proof net.

[0009] Preferably, a rain cover is provided at one end of the heat dissipation fan outside the box; the rain cover includes a cover body portion with one end open, and a connecting portion located at the open end of the cover body portion and fixedly connected to the outer wall of the box; an air inlet is provided on the lower outer wall of the cover body portion.

[0010] Preferably, a back plate is provided in the box body on the side corresponding to the door body, and the back plate is fixedly connected to the box body through a first short column.

[0011] Preferably, a bottom plate is provided at the bottom of the box body, and the bottom plate is fixedly connected to the box body through a second short column.

[0012] The above technical solution has the following advantages:

[0013] 1. This utility model achieves automatic control of the working state of the cooling fan by setting a travel switch inside the box, thereby significantly improving the comfort level during live-line operations. Specifically, when the operator enters the designated work area and opens the box door, the travel switch loses its pressure on the box door, and the cooling fan loses power and stops running. This design not only effectively avoids unnecessary interference to the operator caused by the strong airflow blown by the cooling fan in the continuous working state, ensuring the accuracy of live-line operations and personnel safety; it also fundamentally eliminates the noise and vibration generated by the cooling fan during operation, creating a quieter and more stable working environment for the operator, further improving work efficiency and work quality.

[0014] 2. This utility model, through the addition of a rain cover, aims to comprehensively enhance the performance and reliability of the heat dissipation distribution box in complex outdoor environments. When deployed outdoors, the rain cover fits snugly against the box, forming an effective waterproof barrier that prevents rainwater from penetrating the interior of the box, thereby avoiding potential safety hazards such as damage to electrical components and short circuits caused by rainwater intrusion. This not only extends the service life of the heat dissipation distribution box but also ensures its continuous and stable operation in outdoor environments, fully meeting the stringent requirements of outdoor use and providing a safer and more reliable solution for outdoor power distribution systems in the fields of electricity, communications, transportation, and more.
