Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with excellent heat dissipation performance. Background Art

[0002] As we all know, distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits, and motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] Existing distribution cabinets have certain drawbacks when in use. The cabinet door cannot provide additional heat dissipation. In a hot environment, the heat dissipation mechanism inside the distribution cabinet cannot provide an effective heat dissipation effect for the distribution cabinet. When the temperature inside the distribution cabinet is too high, it will cause the electrical equipment inside the distribution cabinet to overheat, which may cause equipment damage, insulation aging and other problems.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model discloses a power distribution cabinet with excellent heat dissipation performance, comprising a cabinet body 1, a cabinet door 2 is arranged on the cabinet body 1, a plurality of ventilation holes are arranged at the bottom of the cabinet door 2, an inclined plate 3 is arranged at the ventilation hole, a frame 5 is fixedly arranged on the inner wall of the cabinet door 2, a dustproof plate 6 is fixedly arranged inside the frame 5, a baffle 8 is pulled out and arranged on the frame 5, a guide groove 7 is arranged on the inner wall of the frame 5, both sides of the baffle 8 are located inside the guide groove 7, a driven block 9 is fixedly arranged in the middle part of the baffle 8, and a motor 11 is fixedly arranged on the inner wall of the cabinet door 2 The output end of the motor 11 is provided with a driving shaft 10, and the driving shaft 10 is meshed with the driven block 9. When the structure is used, in a hot environment, the motor 11 is started to rotate the driving shaft 10. Through the meshing effect, the driven block 9 can drive the baffle 8 to move upward in the frame 5, and the multiple ventilation holes at the bottom of the cabinet door 2 can be connected with the cabinet 1. At this time, through the multiple ventilation holes, an additional ventilation effect can be provided in the cabinet 1. On the basis of the original heat dissipation of the cabinet 1, the heat dissipation effect of the cabinet 1 can be enhanced to prevent the electrical equipment inside the cabinet 1 from overheating;

[0023] In rainy weather, the ambient temperature is low, and the baffle 8 can be reset. The baffle 8 can block the ventilation holes on the cabinet door 2 to prevent rainwater and other impurities from entering the cabinet body 1. The dustproof plate 6 can prevent dust and impurities outside the cabinet door 2 from entering the cabinet body 1.

[0024] Furthermore, the motor 11 can be a servo motor 11 .
