[0001] This utility model relates to the field of electrical cabinet technology, and in particular to a generator set control cabinet. Background Technology

[0002] A generator set control cabinet is an electrical device that integrates various electrical components such as contactors, circuit breakers, fuses, and relays. Also known as an electrical control cabinet, it is used for power control and protection of motors, loads, and other equipment. In existing generator set control cabinets, the control circuit module and power supply module are usually designed as an integrated unit, meaning they are tightly integrated and connected through internal circuitry. However, after installation, if a module in this integrated system malfunctions, more complex operations are required to locate and repair the problem, increasing maintenance difficulty and cost. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a contactor cabinet in which the control module and the power supply module are installed independently and modularly, which facilitates later maintenance.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A generator set control cabinet includes: a cabinet body, a power supply module, a control module, and an electronic connector. The cabinet body has a mounting cavity, and the power supply module, the control module, and the electronic connector are all mounted in the mounting cavity. The electronic connector is provided with an input interface and an output interface. The power supply module is electrically connected to the input interface, and the control module is electrically connected to the output interface.

[0006] Furthermore, a support base is provided inside the mounting cavity, and the electronic connector is mounted on the support base.

[0007] Furthermore, a first mounting plate is provided inside the mounting cavity, and the support base is mounted on the first mounting plate.

[0008] Furthermore, the power supply module includes at least a first circuit breaker and a contactor, and the electronic connector is provided with multiple input interfaces. The output terminals of the circuit breaker and the contactor are electrically connected to the input interfaces respectively.

[0009] Furthermore, a second mounting plate is provided inside the mounting cavity, which is spaced apart from the first mounting plate, and the control module is mounted on the second mounting plate.

[0010] Furthermore, the control module includes at least a relay, a terminal block, and a second circuit breaker. The electronic connector is provided with multiple output interfaces. After the relay, terminal block, and circuit breaker are respectively installed on the second mounting plate, they are electrically connected to the multiple output interfaces through cables.

[0011] Furthermore, both the first mounting plate and the second mounting plate are provided with a plurality of first through holes, and the inner wall of the mounting cavity is provided with a plurality of second through holes. The plurality of first through holes and the plurality of second through holes are used for connecting the connector.

[0012] Furthermore, both the first mounting plate and the second mounting plate are made of insulating material.

[0013] Furthermore, the cabinet is provided with multiple heat dissipation holes, which are used to dissipate heat from the mounting cavity.

[0014] Furthermore, the cabinet body is provided with a cabinet door, which is rotatably connected to the cabinet body and is used to open or close the mounting cavity when rotated.

[0015] Compared with the prior art, the advantages of this utility model are as follows: its power supply module and control module are independent units, which are electrically connected to the input and output terminals of the electronic connector, respectively. In this way, if the power supply module or the power supply module fails, the user can more easily locate and replace the module, and select or replace the components of the individual module as needed, without having to replace the entire system, thus reducing the difficulty and cost of maintenance. In addition, since the two modules are set independently, the failure of a single module is less likely to affect the normal operation of other modules, thereby reducing the risk of the entire system.

[0021] The present invention will now be further described in conjunction with specific embodiments:

[0022] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] like Figures 1-3 As shown, a generator set control cabinet includes a cabinet 10, a power supply module 30, a control module, and an electronic connector 40. The cabinet 10 has a mounting cavity 11, in which the power supply module 30, the control module, and the electronic connector 40 are all mounted. The electronic connector 40 is provided with an input interface and an output interface. The power supply module 30 is electrically connected to the input interface, and the control module is electrically connected to the output interface.

[0025] Based on the above structure, during assembly, the output end of the power supply module 30 is connected to the input interface of the electronic connector 40, and then the control module is connected to the output end of the electronic connector 40, so that the power supply module 30 can distribute electrical energy to the control module to meet the working needs of the control module.

[0026] Specifically, since the power supply module 30 and the control module are independent units, and are electrically connected to the input and output interfaces of the electronic connector 40 respectively, if the power supply module 30 or the control module 30 fails, it is easier for the user to locate and replace the module, and select or replace the components of the individual module as needed, without having to replace the entire system, thus reducing the difficulty and cost of maintenance. In addition, since the two modules are set up independently, the failure of a single module is less likely to affect the normal operation of other modules, thereby reducing the risk of the entire system.

[0027] It should be noted that the power supply module 30 in this embodiment can be composed of components such as circuit breakers, contactors 22 or transformers installed in the cabinet 10. The power supply module 30 is responsible for the distribution, protection or switching of electrical energy, and delivers electrical energy safely and stably to the control module (such as a circuit breaker, a PLC controller or a terminal block 32 or other actuators) through an electronic connector 40 (such as a bus connector) so that the control module can work stably.

[0028] Furthermore, a support base 41 is provided inside the mounting cavity 11. During assembly, the support base 41 can be fixed inside the mounting cavity 11 by means of connectors (such as screws or bolts). Then, the electronic connector 40 is also installed on the support base 41 by means of connectors (such as bolts, nuts, bayonets, etc.) to fix the electronic connector 40 by means of the support base 41, so as to prevent the electronic connector 40 from loosening or falling off after being connected to the power supply module 30 or the control module, so as to make the whole structure more stable.

[0029] It should be noted that the electronic connector 40 in this embodiment can be an existing busbar connector, and the support base 41 can be an existing busbar support base 41. In addition, the support base 41 can also be made of insulating materials (such as epoxy resin, polyvinyl chloride (PVC) or ceramics) to give it an insulating function in order to avoid short circuits or other faults.

[0030] Furthermore, a first mounting plate 12 is provided inside the mounting cavity 11. During assembly, the support base 41 is mounted on the first mounting plate 12, and then connected to the inner wall of the mounting cavity 11 through the first mounting plate 12. This increases the connection area between the support base 41 and the inner wall of the mounting cavity 11, providing a more stable support foundation for the support base 41, allowing it to be more firmly fixed inside the cabinet 10. In this way, when the electronic connector 40 and other electrical components are connected to it, the support base 41 is not easy to loosen, making the entire installation structure more stable.

[0031] It should be noted that the first mounting plate 12 can be detachably connected to the inner wall of the mounting cavity 11 using screws, bolts and other connectors, so that the power supply module 30 on the support base 41 can be removed for inspection and maintenance at any time, which is convenient for later maintenance.

[0032] More specifically, the power supply module 30 in this embodiment includes at least a first circuit breaker 21 and a contactor 22. The electronic connector 40 is provided with multiple input interfaces. During assembly, the output terminals of the circuit breaker and the contactor 22 are electrically connected to the multiple input interfaces on the electronic connector 40 through cables. In this way, when a short circuit, overload or other fault occurs in the circuit, the power supply can be quickly cut off by the circuit breaker, thereby protecting the contactor 22 and other electrical equipment from damage.

[0033] Furthermore, a second mounting plate 13 is provided in the mounting cavity 11. During assembly, after the control module and the second mounting plate 13 are fixed together by connectors, the second mounting plate 13 is installed inside the cabinet 10 by connectors (such as screws or bolts) so as to stably support the control module through the second mounting plate 13.

[0034] In addition, the spacing between the first mounting plate 12 and the second mounting plate 13 can prevent electrical components or cables on the first mounting plate 12 and the second mounting plate 13 from coming into contact or getting tangled, which could lead to short circuits and indirectly reduce the risk of short circuits, thus making the structure safer.

[0035] More specifically, in this embodiment, the control module includes at least a relay 31, a terminal block 32, and a second circuit breaker 33. Multiple output interfaces are provided on the electronic connector 40. During assembly, the relay 31, terminal block 32, and second circuit breaker 33 are respectively installed on the second mounting plate 13 and electrically connected to the multiple output interfaces via cables. The terminal block 32 connects various important components in the circuit, enabling smooth signal and power transmission between components. The relay 31 controls the connection and disconnection of the circuit, and the second circuit breaker 33 controls the automatic switching of the circuit. In the event of a short circuit, overload, or other fault, the second circuit breaker 33 quickly cuts off the power supply, thereby protecting the electrical equipment in the entire control module from damage and making the system safer.

[0036] Furthermore, both the first mounting plate 12 and the second mounting plate 13 are provided with multiple first through holes, and the inner wall of the mounting cavity 11 is provided with multiple second through holes. During assembly, the multiple first through holes and the multiple second through holes can be set one-to-one and used to connect connecting parts (such as screws or bolts) so that the first mounting plate 12 and the second mounting plate 13 can be locked in the mounting cavity 11, making the entire mounting structure more stable.

[0037] Specifically, in this embodiment, both the first mounting plate 12 and the second mounting plate 13 are made of insulating materials, such as epoxy resin, polyvinyl chloride (PVC), thermoplastic elastomer (TPE), etc., so that the first mounting plate 12 and the second mounting plate 13 have good insulation performance, which can effectively isolate the current between the bus connector, power supply module 30 and control module installed with them and the surrounding metal structure, avoid current leakage or short circuit, and make them safer to use.

[0038] Furthermore, a cabinet door 14 is provided on the cabinet body 10. The cabinet door 14 is rotatably connected to the cabinet body 10, so that the cabinet door 14 can open or close the cabinet body 10 when it is rotated, so that the user can open and close the cabinet door 14 at any time to maintain the electrical components of the installation cavity 11.

[0039] Specifically, in this embodiment, the cabinet door 14 and the cabinet body 10 can be rotatably connected by hinges (such as hinges or door hinges).

[0040] In addition, since the electrical components inside the mounting cavity 11 may release a lot of heat during use, if it is not dissipated in time, it may cause the internal components to overheat and be damaged. Therefore, in this embodiment, multiple heat dissipation holes 15 are provided on the cabinet 10, and the multiple heat dissipation holes 15 are connected to the mounting cavity 11 so as to dissipate the heat inside the mounting cavity 11 through the multiple heat dissipation holes 15, reduce the risk that the electrical components inside the mounting cavity 11 will be affected by excessive internal temperature, and indirectly improve the service life of the electrical components inside the mounting cavity 11.

[0041] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
