Description

Technical Field

[0001] The utility model belongs to the technical field of control cabinets, and more specifically, particularly relates to a control cabinet shell assembly with a moisture-proof structure. Background Art

[0002] The control cabinet is a combination of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, be easy to maintain, and not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of faults or abnormal operation, the circuit can be cut off or an alarm can be given with the help of protective electrical appliances. Various parameters in operation can be displayed with the help of measuring instruments, and certain electrical parameters can be adjusted. It can also prompt or send signals when the normal working state is deviated. It is often used in various power generation, distribution and substations.

[0003] Based on the above, the inventors have discovered the following problems: the control cabinet usually dissipates heat from its interior when in use, but during the heat dissipation process, especially on rainy days, air carrying moisture will enter the interior of the control cabinet. The humid air can easily cause malfunctions to electrical components, and in severe cases, a fire may occur, reducing safety protection.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a control cabinet housing assembly with a moisture-proof structure is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0006] The purpose and effect of the control cabinet housing assembly with moisture-proof structure of the utility model are achieved by the following specific technical means:

[0007] A control cabinet housing assembly with a moisture-proof structure comprises a control cabinet housing and a top cover fixedly mounted on the top of the control cabinet housing, a cabinet door is arranged in front of the control cabinet housing, an exhaust fan for air circulation is arranged at the bottom of the top cover, a moisture-proof mechanism for drying the air inside the control cabinet housing is arranged at the rear of the control cabinet housing, the moisture-proof mechanism comprises a moisture-proof box, and a cooling component for the air inside the control cabinet housing is arranged below the moisture-proof box.

[0008] Furthermore, the moisture-proof mechanism also includes a second placement frame, the inner side of which is installed with a desiccant for drying the air in the control cabinet housing, and the right side of the moisture-proof box has a sealing door for sealing the moisture-proof box.

[0009] Furthermore, a first placement frame is fixedly installed on the inner side of the moisture-proof box, a filter layer for filtering dust in the control cabinet housing is installed on the inner side of the first placement frame, and the first placement frame is located below the second placement frame.

[0010] Furthermore, the cooling component includes a heat dissipation pipe, which is a curved structure and is located on the outside of the control cabinet shell. The top of the heat dissipation pipe is fixedly connected to the moisture-proof box, and the left and right inner walls of the control cabinet shell are fixedly installed with an exhaust box, and the bottom end of the heat dissipation pipe is fixedly connected to the exhaust box.

[0011] Furthermore, a cavity is opened on the inner side of the top cover, and the cavity is connected to and corresponds to the exhaust fan. Two exhaust pipes are fixedly installed between the moisture-proof box and the top cover. The top end of the exhaust pipe is connected to the cavity, and the bottom end of the exhaust pipe is connected to the top of the moisture-proof box.

[0012] Furthermore, the bottom of the control cabinet housing has a base for supporting and fixing the control cabinet housing.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, the desiccant arranged by the moisture-proof mechanism can absorb and dry the moisture in the air. The arrangement of the second placement frame facilitates the periodic replacement of the desiccant, thereby increasing the drying effect of the air inside the control cabinet housing. The arrangement of the filter layer can filter the dust in the air, thereby reducing the pollution and damage to the electrical components by the dust.

[0015] In the utility model, negative pressure is drawn into the moisture-proof box through an exhaust fan and an exhaust pipe, and air can be exhausted into the control cabinet shell through the heat dissipation pipe and the exhaust box, and the air in the control cabinet shell is drawn into the moisture-proof box. The air can exchange heat through the heat dissipation pipe to reduce the temperature of the air passing through the heat dissipation pipe. After being dried by the moisture-proof mechanism, it is transported to the cavity through the exhaust pipe, and the electrical components in the control cabinet shell are cooled by the exhaust fan to increase the cooling effect.
