On the other hand, rainwater and impurities from the outside can easily enter the interior of the switchgear, which may cause faults such as short circuits and reduce the service life of electrical components. In order to solve the above problems, we propose a compact low-voltage switchgear. Utility Model Content

When in use, the position of the sliding plate 32 is adjusted according to the specifications of the electrical components in the switch cabinet, and the sliding plate 32 is fixed to the slide rail 31 by bolts. The electrical components are placed in the placement device 3, and the adjacent electrical components are isolated by the isolation component 33, so that there is a certain distance between the electrical components, which is convenient for ventilation and heat dissipation of the electrical components. When in use, close the rotating door 2 and place the cabinet 1 at the workplace. The rain shield 6 covers the cabinet 1 to prevent rainwater from entering the interior of the cabinet 1 through the top of the cabinet 1. At the same time, the fan 5 is started to drive the air flow inside the cabinet 1 to flow outward, and the external air flow enters the interior of the cabinet 1 along the ventilation device 4.

[0021] The isolation assembly 33 includes a limit plate 331, the bottom of the limit plate 331 is fixedly connected to the two sides of the sliding plate 32, the bottom of the limit plate 331 is slidably connected to a sliding block 332, the bottom of the sliding block 332 is slidably connected to the top of the sliding plate 32, and the top of the sliding block 332 is fixedly connected to the isolation plate 333. A positioning hole 334 is opened in the wall of the limit plate 331, and a latch 335 is slidably connected to the inner side of the positioning hole 334. When in use, the sliding block 332 in the isolation assembly 33 is moved so that the electrical components are placed between the two adjacent isolation plates 333. The isolation plates 333 separate the electrical components so that there is a certain distance between the adjacent electrical components to facilitate gas circulation. Subsequently, the latch 335 is passed through the positioning hole 334 in the limit plate 331 so that the latch 335 is inserted into the sliding block 332 to fix the sliding block 332.

[0022] The ventilation device 4 includes an outer shell 41, the outer side of the outer shell 41 is fixedly connected to both sides of the cabinet 1, the outer side of the outer shell 41 is fixedly connected to an air inlet plate 42, and the inner side of the outer shell 41 is fixedly connected to a guide plate 43. When in use, the external airflow follows the air inlet plate 42 into the interior of the outer shell 41. Since the air inlet plate 42 is arranged below the ventilation device 4, when the airflow enters the cabinet 1, it needs to flow upward along the guide plate 43. Heavier rainwater and impurities cannot be carried by the airflow and will not follow the airflow into the interior of the cabinet 1.

[0023] A sieve plate 44 is fixedly connected to the top of the guide plate 43, and the outer side of the sieve plate 44 is fixedly connected to the inner side of the outer shell 41. A drying component 45 is fixedly connected to the outer side of the sieve plate 44.

When in use, the desiccant bag 453 in the drying component 45 absorbs moisture in the air flow. When the desiccant bag 453 has been used for a long time, the sliding bin 452 is pulled out along the connecting plate 451, and the desiccant bag 453 is replaced. Then, the sliding bin 452 is put back to the connecting plate 451.

[0025] Working principle:

[0026] During use, the position of the sliding plate 32 is adjusted according to the specifications of the electrical components in the switch cabinet, and the sliding plate 32 is fixed to the slide rail 31 by bolts. The electrical components are placed in the placement device 3, and the sliding block 332 in the isolation assembly 33 is moved so that the electrical components are placed between two adjacent isolation plates 333. The isolation plates 333 separate the electrical components so that there is a certain distance between adjacent electrical components to facilitate gas circulation. Subsequently, the latch 335 is passed through the positioning hole 334 in the limiting plate 331 so that the latch 335 is inserted into the sliding block 332 to fix the sliding block 332;

[0027] When in use, close the rotating door 2, place the cabinet 1 at the work site, and shield the cabinet 1 with the rain shield 6 to prevent rain from entering the cabinet 1 through the top of the cabinet 1. At the same time, the fan 5 is started to drive the air inside the cabinet 1 to flow outward, and the external air flows into the cabinet 1 along the ventilation device 4;

[0028] When the fan 5 drives the airflow, the external airflow follows the air inlet plate 42 and enters the interior of the housing 41. Since the air inlet plate 42 is arranged below the ventilation device 4, when the airflow enters the cabinet 1, it needs to flow upward along the guide plate 43. The heavier rainwater and impurities cannot be carried by the airflow and will not follow the airflow into the interior of the cabinet 1. The airflow moves upward to the sieve plate 44, which filters the impurities in the airflow. The desiccant bag 453 in the drying assembly 45 absorbs moisture in the airflow.

[0029] When the desiccant pack 453 has been used for a long time, the sliding compartment 452 is pulled out along the connecting plate 451 , and the desiccant pack 453 is replaced. Subsequently, the sliding compartment 452 is put back to the connecting plate 451 .

[0030] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
