GGD low-voltage switchgear has the characteristics of good dynamic thermal stability, novel and reasonable structure, practical electrical scheme, strong series usability, high protection level, etc. It is widely used in power plants, substations, factories and mines and other power users. It is used as a power distribution system with AC 50-60Hz and rated working current up to 3150A for power conversion, distribution and control of power, lighting and distribution equipment. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN212774030U discloses a GGD type low-voltage switch cabinet with a safety protection structure, wherein a cabinet door is provided on one side of the switch cabinet body, a cabinet door is installed inside the cabinet door, a first slide plate is fixedly installed on the upper and lower parts of one side of the inner cavity of the switch cabinet body, a second slide plate is fixedly installed on the upper and lower parts of one side of the cabinet door, and a connecting moving part is connected between the first slide plate and the second slide plate. The switch cabinet body of the low-voltage switch cabinet is mostly a rectangular parallelepiped, which makes it difficult to fully utilize the internal space when designing the device internally, and in order to prevent the opening of the cabinet door from being affected by the environment or affecting the operation of the staff, the cabinet door design structure is relatively complex, and the operation difficulty is relatively high, which increases the cost and reduces the convenience of use;

[0004] When installing and using low-voltage switchgear, we should try our best to avoid vibration and impact caused by the external environment on the cabinet to avoid damage or falling of circuit components, which will limit the scope of use of the low-voltage switchgear. However, since the switchgear often needs to be operated and used, its installation location cannot be too remote, and it is inevitable that its outer side will be hit, affecting the service life of the switchgear and circuit components.

[0008] The heat dissipation fan can drive the flow of air to dissipate heat in the rotating mounting frame, further cool the circuit components, and prevent the circuit components from being damaged due to overheating. When the distribution cabinet is in use, the outer peripheral surface of the distribution cabinet body can be protected by inflating the protective airbag, and the positions of multiple protective airbags can be adjusted according to the environment, thereby improving the flexibility of use and reducing the probability of the distribution cabinet and circuit components being damaged by impact. The switch cabinet body is a cylinder, so that the front cover can be rotated and opened and closed with the center of the switch cabinet body as the axis, which is not affected by the external environment and will not affect the operation of the staff. At the same time, it has a simple structure and is easy to operate. The rotating mounting frame can rotate in the switch cabinet body, so that the components can be installed at any position on the outer peripheral surface of the rotating mounting frame. While reducing the volume of the switch cabinet, the number of circuit components that can be installed in a single switch cabinet is increased, and when a single component needs to be operated, the circuit component can be moved to a position convenient for the staff to operate by rotating the rotating mounting frame, thereby improving the convenience of use.

[0009] Furthermore, an exhaust port is provided through the bottom of the outer peripheral surface of the support base, a first limit frame is welded through the center of the top of the support base, a rotating slide groove is provided on the top edge of the support base, the bottom of the rotating mounting frame is clamped in the first limit frame, and the exhaust port is connected through the first limit frame and the rotating mounting frame;

[0010] The support base can support the switch cabinet body and improve the stability of the switch cabinet body during use.

[0012] The heat dissipation fan can drive the flow of air, and the flow of air can dissipate the heat inside the rotating mounting frame, further cooling the circuit components installed on the outer peripheral surface of the rotating mounting frame, thereby preventing the circuit components from being damaged due to overheating. The air pump can inflate the protective airbag, causing the protective airbag to expand and protect the outer peripheral surface of the distribution cabinet body, thereby reducing the probability of the distribution cabinet and circuit components being damaged by impact.

[0013] Furthermore, the inner wall of the switch cabinet box is rotatably connected with a front cover, one end of the front cover is welded and fixed with a rotating handle, and the rotating handle penetrates and is inserted into the outer peripheral surface of the switch cabinet box;

[0014] The switch cabinet body is cylindrical, so that the front cover can rotate with the center of the switch cabinet body as the axis. The opening and closing of the front cover is not affected by the external environment and will not affect the operation of the staff. At the same time, the structure is simple and the operation is convenient. By rotating the rotating mounting frame, a large number of circuit components are installed and fixed on the outer peripheral surface of the rotating mounting frame and connected by retractable wires. While reducing the volume of the switch cabinet, the number of circuit components that can be installed in a single switch cabinet is increased. When a single component needs to be operated, the circuit component can be moved to a position convenient for the staff to operate by rotating the rotating mounting frame, thereby improving the convenience of use.

[0016] The heat conduction area of ​​the rotating mounting frame can be increased by using a plurality of heat-conducting fins. When the temperature of the circuit components rises to a threshold value, the heat dissipation fan drives the air flow to cool down the rotating mounting frame, and further cools down the circuit components. The flowing air will not enter between the rotating mounting frame and the switch cabinet body, thereby preventing dust contained in the air from damaging the components. When the temperature inside the switch cabinet body is too low, the plurality of heat-conducting fins are heated by the heating rod, and the rotating mounting frame is further heated, so that the switch cabinet body is at an appropriate temperature, thereby ensuring the normal operation of the circuit components.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that most switch cabinets of low-voltage switch cabinets are in the form of rectangular parallelepiped, which makes it difficult to fully utilize the internal space when designing the device internally, and in order to prevent the opening of the cabinet door from being affected by the environment or affecting the operation of the staff, the cabinet door design has a relatively complex structure and high difficulty in operation, which increases the cost and reduces the convenience of use. The switch cabinet body is a cylinder, so that the front cover can rotate with the center of the switch cabinet body as the axis. The opening and closing of the front cover is not affected by the external environment and will not affect the operation of the staff. At the same time, the structure is simple and the operation is convenient.

[0019] The utility model solves the problem that the low-voltage switch cabinet should avoid vibration and impact caused by the external environment to the cabinet body as much as possible during installation and use to avoid damage or falling of circuit components, thereby limiting the use range of the low-voltage switch cabinet. However, since the switch cabinet often needs to be operated and used, its installation position cannot be too remote, and it is inevitable that its outer side will be hit, affecting the service life of the switch cabinet and circuit components. When the distribution cabinet is in use, the outer peripheral surface of the distribution cabinet body can be protected by inflating the protective airbag, and the positions of multiple protective airbags can be adjusted according to the environment, thereby improving the flexibility of use and reducing the probability of the distribution cabinet and circuit components being damaged by impact.
