Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a novel power distribution cabinet. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in the occasions where the load is relatively dispersed and there are fewer circuits. The motor control center is used in the occasions where the load is concentrated and there are more circuits. They distribute the power 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. The electrical components inside the power distribution cabinet will generate heat during use, and the heat dissipation effect of the existing power distribution cabinet is mostly poor, which affects the service life of the electrical components in the power distribution cabinet. Therefore, it needs to be improved.

[0003] After searching, a Chinese patent with publication number CN 210628765 U mentioned a new type of power distribution cabinet, including a bottom box, a protective box connected to the top of the bottom box by bolts, a plurality of support plates fixedly installed on the inner wall of the protective box, an inner box connected to the inside of the protective box by the support plates, two dovetail grooves are provided on the inner walls on both sides of the inner box, the inner box is connected to a mounting mechanism for mounting electrical components through four dovetail grooves, the mounting mechanism is composed of four sliders, a mounting plate and a plurality of mounting holes, a water tank is arranged at the bottom of the inner cavity of the bottom box, and a submersible water pump is arranged at the bottom of the inner cavity of the water tank. The utility model uses a submersible water pump and a cooling pipe to extract the water inside the water tank and spray it on the outer surface of the inner box through the through hole, thereby cooling the inside of the inner box, thereby avoiding high temperature affecting the service life of the electrical components, and the water sprayed on the inner box falls into the water tank, and the water inside the water tank is cooled by the refrigeration plate, thereby realizing the recycling of water.

[0004] The above-mentioned device has drawbacks during specific use. During the application process, the applicant discovered that the above-mentioned device dissipates heat inside the box by setting up a submerged water pump and a cooling pipe. However, during specific use, the heat dissipated inside the box by water cooling may further cause moisture in the gas inside the box. Further humid air may further cause the components inside the box to become damp and damaged. Although it plays a heat dissipation role to a certain extent, it also increases the maintenance cost of the components. Utility Model Content

[0016] When the utility model needs to dissipate heat for the electrical components inside the cabinet, the control switch is electrically connected to the servo motor. Further, the staff uses the control switch to start the servo motor. At this time, the servo motor drives the connecting shaft and the fan blades to rotate, further generating wind inside the cabinet. The wind enters into the upper space of the cabinet through the ventilation hole plate, and then carries the heat generated by the components to be discharged outside through the heat dissipation mesh plate, thereby facilitating the heat dissipation treatment inside the cabinet. The air-cooled heat dissipation effect is better and it is not easy to make the air inside the cabinet humid.

[0017] According to the utility model, when the humidity of the outside air is relatively high, the controller is electrically connected to the electric push rod, and then the staff starts the electric push rod through the controller, and the output end of the electric push rod is further extended, driving the baffle plate to slide with the sliding groove opening opened on one side wall of the groove rod. When the baffle plate rises, the exposed area of ​​the ventilation window is reduced, and then the amount of outside air entering the cabinet is reduced, thereby avoiding the accumulation of too much humid air inside the cabinet and causing damage to internal components.
