Description

Technical Field

[0001] The utility model relates to the technical field of soft start control cabinets, and more specifically, to a moisture-proof soft start control cabinet. Background Art

[0002] The soft start control cabinet mainly reduces the starting current of the motor, reduces the power distribution capacity, avoids the investment of capacity increase, reduces the starting stress, and prolongs the service life of the motor and related equipment. It has multiple starting modes and a wide range of current, voltage and other settings, which can adapt to various load conditions. The control cabinet is widely used in loads such as fans, water pumps, conveyors and compressors. The humidity in the cabinet is high, which will affect the use of the electrical components in the control cabinet. In severe cases, they may be damaged or even exploded. Therefore, a moisture-proof soft start control cabinet is needed.

[0003] In order to prevent excessive humidity inside the traditional control cabinet, a fan is used to blow out the humid air in the control cabinet. However, this requires the fan to work for a long time, which is easy to be damaged, and has high power consumption. It is also easy to generate heat, increase the temperature inside the control cabinet, and affect the operation of electronic components.

[0004] The utility model with Chinese patent application number CN202122359539.4 discloses a moisture-proof soft-start control cabinet, including a cabinet body and a moisture-proof box. The cabinet body is provided with ventilation holes and a humidity sensor. The moisture-proof box is fixed on the right end face of the cabinet body. The moisture-proof box is provided with a desiccant placement chamber, a hot air blower placement chamber and a partition net. The desiccant placement chamber is located on the left side of the hot air blower placement chamber. The partition net separates the desiccant placement chamber from the hot air blower placement chamber. Cotton cloth, desiccant particles and cotton cloth are placed in the desiccant placement chamber from left to right in sequence. A hot air blower is provided in the hot air blower placement chamber. The right end face of the cabinet body is connected to the left end face of the moisture-proof box through moisture absorption holes. The device of the present application adopts a dry desiccant to maintain the humidity in the control cabinet. When the humidity value in the control cabinet is detected to be large, the hot air blower is turned on to dehumidify the desiccant so that the desiccant can be recycled.

[0005] Then, combined with the drawings in its specification, it can be seen that the purpose of dehumidification and moisture-proofing is achieved by setting a drying box on one side of the cabinet, and an air inlet is set on the other side. When the external air is humid, it is easy for external moisture to enter the interior of the cabinet through the air inlet, resulting in different humidity on both sides of the cabinet, affecting the moisture-proof effect of the cabinet.

[0040] When the dustproof net 21 is a sealing plate, the moisture inside the cabinet 1 is detected by the humidity sensor 22, and the moisture inside the cabinet 1 is absorbed by the desiccant in the middle of the first drying box 5 and the second drying box 6 through the hot air box 9, the porous plate 4 and the second through hole 7, so as to remove moisture from both the upper and lower sides at the same time;

[0041] When the humidity inside the cabinet 1 is high, the hot air blower in the middle of the hot air box 9 can be started to blow the humidity inside the cabinet 1 into the middle of the second drying box 6, and the humidity in the middle of the second drying box 6 is discharged through the exhaust strip hole 10. At the same time, the external air will enter the interior of the first drying box 5 through the air inlet strip hole 15 to push the movable baffle 13. The first drying box 5 dehumidifies the incoming air, so that the air entering the cabinet 1 is always kept dry, which can achieve a moisture-proof effect on the interior of the cabinet 1.

[0042] When the cabinet 1 needs to be cooled, a dust screen 21 may be installed inside the card frame 20 to prevent external dust from entering the cabinet 1 . In this case, the dryness of the air entering the cabinet 1 cannot be guaranteed.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
