[0019] The present invention is further described in detail below in conjunction with the embodiments and drawings. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0020] Example

[0021] See also Figure 1-Figure 3 A load cabinet for a generator includes a cabinet body 1, a bridge frame 2 is arranged in the cabinet body 1, the bridge frame 2 is used to fix the power cable, a copper busbar electrically connected to the power cable is arranged in the cabinet body 1, and a resistor 3 is connected to the copper busbar.

[0022] In this embodiment, a copper bar is arranged in the cabinet 1, the copper bar is connected to the power cable, and then the resistor 3 is electrically connected to the copper bar to achieve electrical connection. The resistor 3 can be replaced separately, which is simple to operate and convenient to maintain; in addition, the setting of the copper bar not only improves the transmission efficiency of the current, but also enhances the stability and reliability of the system, ensuring that key components such as the resistor 3 and the copper bar are not easily damaged due to overheating during long-term operation.

[0023] In this embodiment, the copper busbar is a card-type structure, and the card-type structure is used to be carded with the terminal of the resistor 3. The copper busbar with the card-type structure ensures good contact performance with the resistor 3 and realizes the rapid installation and removal of the resistor 3, so that the resistor 3 can be quickly replaced when necessary, reducing downtime; it is also convenient to perform regular inspection and maintenance on the resistor 3, improving the maintenance efficiency and safety of the entire load cabinet.

[0024] In this embodiment, a mounting frame is provided in the cabinet 1, and the resistor 3 is fixed in the mounting frame. The provision of the mounting frame further improves the stability of the resistor 3 and avoids the risk of movement or falling under vibration and impact of the resistor 3. The mounting frame in this embodiment can be made of high-strength material, ensuring that the resistor 3 can be kept in a predetermined position under high-load working conditions, avoiding poor contact or short circuit problems caused by vibration, thereby ensuring the long-term stable operation of the load cabinet.

[0025] In this embodiment, a lifting ring 4 is installed on the top of the cabinet 1 to facilitate lifting operations during installation and maintenance. The lifting ring 4 in this embodiment is made of high-strength steel to ensure safety and reliability when bearing the weight of the load cabinet. In addition, the design position of the lifting ring 4 needs to consider the center of gravity of the load cabinet to ensure the balance of the cabinet 1 during lifting.

[0026] In this embodiment, the cabinet body 1 is provided with a door panel 6, and the door panel 6 is a double-leaf structure; the door panel 6 is provided with a lock body 7 that can lock the double-leaf door panel 6 structure; and a light strip is provided inside the door panel 6. When the cabinet door is closed, the light strip can provide uniform lighting, which is convenient for operators to perform inspection and maintenance work in the cabinet. In addition, the double-leaf design of the door panel 6 is not only convenient for daily switch operations, but also can be quickly opened in an emergency, ensuring the safety of personnel and rapid maintenance of equipment. The design of the lock body 7 ensures that the cabinet body 1 can be safely locked in a non-operating state, preventing unauthorized personnel from opening the cabinet door at will, thereby increasing the safety of the load cabinet.

[0027] In this embodiment, a protective plate 5 for protecting internal components is installed on the top of the cabinet 1, which can effectively prevent the external environment from damaging the components in the cabinet. The protective plate 5 can be made of high temperature resistant and corrosion resistant materials.

[0028] In this embodiment, the top surface of the cabinet 1 is provided with ventilation holes 8, which are designed to help dissipate the heat in the cabinet and ensure the stability of the temperature in the cabinet. In addition, the edges of the ventilation holes 8 are also provided with dustproof nets, which further enhance the dustproof effect, meet the heat dissipation requirements, and prevent the entry of foreign substances such as dust and water droplets, protect the sensitive electrical components in the cabinet, and ensure the long-term stable operation of the load cabinet.

[0029] In some other embodiments, the bottom of the cabinet 1 is provided with support feet with adjustable height to adapt to the flatness requirements of different floors. The design of the support feet makes the load cabinet more stable during installation and maintenance, and avoids the cabinet 1 from tilting or shaking due to uneven ground. Each support foot is equipped with a locking device to ensure that it can be firmly locked after adjusting to the appropriate height to prevent accidental movement during use. In addition, the bottom of the support foot is also provided with an anti-slip pad to increase the friction between the load cabinet and the ground, further ensuring the stability and safety of the load cabinet.

[0030] In some other embodiments, a temperature sensor is provided inside the cabinet 1 for real-time monitoring of the temperature inside the cabinet and connected to the control system to achieve overheat protection. In particular, when the temperature exceeds a preset safety threshold, the control system will automatically start a cooling system to reduce the temperature inside the cabinet and prevent equipment damage caused by overheating.

[0031] In addition, in some other embodiments, a humidity sensor may be provided inside the cabinet 1 to detect the humidity level inside the cabinet to prevent electrical failures caused by excessive humidity. The control system will also adjust the dehumidification equipment inside the cabinet according to the feedback from the humidity sensor to ensure the dryness of the environment inside the cabinet. These intelligent monitoring and adjustment mechanisms greatly improve the reliability and safety of the load cabinet and provide a strong guarantee for the stable operation of the generator.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
