Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of generators, in particular to a cabinet-type double-switch cabinet generator set. Background Art
[0002] The circuit breaker is an important device in the generator set used to cut off and connect the load circuit, as well as to cut off the fault circuit. It can effectively prevent the accident from expanding and ensure the safe operation of the circuit. Since different load devices have different current and power requirements, the rated current of the circuit breaker should be greater than or equal to the maximum working current of the load device. If the rated current of the circuit breaker is too small, when the load device is working, the circuit breaker may trip due to overload, affecting the continuity and stability of the power supply. Therefore, for load devices with different current requirements, circuit breakers with different rated currents need to be selected. Traditional generator sets only have a single outlet circuit breaker and can only adapt to one overload protection condition. When it is necessary to power another set of load devices, it is necessary to replace the circuit breaker of different specifications. Its operation is not convenient and lacks flexibility.

[0020] Next, in combination with specific embodiments, the present utility model will be further described:
[0021] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.
[0023] As Figures 1 to 3 shown, a cabinet-type double-switch cabinet generator set includes a cabinet body 10, a generator set 30, and a circuit breaker 21. The cabinet body 10 has an installation cavity 11. There are two circuit breakers 21. Both of the two circuit breakers 21 and the generator set 30 are installed in the installation cavity 11. The generator set 30 has two output interfaces, and the two circuit breakers 21 are respectively electrically connected to the two output interfaces.
[0024] On the basis of the above structure, during assembly, after the generator set 30 is installed in the installation cavity 11, the two output interfaces are placed facing the input ends of the two circuit breakers 21, and then the input ends of the two circuit breakers 21 are respectively electrically connected to the two output interfaces, while the output ends of the two circuit breakers 21 are respectively used to connect to the load devices (such as electric motors, air conditioners, or electric fans, etc.) that need to be powered.
[0025] Specifically, the two circuit breakers 21 can respectively select circuit breakers 21 with different rated current magnitudes to be electrically connected to the output interfaces of the generator set 30. Because when the power or rated current of the load devices that need to be powered is different, the load devices can select suitable circuit breakers 21 to connect according to the actual power magnitude or rated current, so that during the power supply process, different circuit breakers 21 can provide different safety protections for different load devices, making the use safer.
[0026] Since different load devices have different current and power requirements, the rated current of the circuit breaker should be greater than or equal to the maximum operating current of the load device. If the rated current of the circuit breaker is too small, when the load device is operating, the circuit breaker may trip due to overload, affecting the continuity and stability of power supply. Therefore, when using the cabinet-type dual switch cabinet generator set in this embodiment, since the output ends of the generator set 30 are respectively connected to the load device through two circuit breakers 21 with different rated currents, during the power supply process of the generator set 30, it can meet the safety conditions of load devices with different powers or rated currents, provide a more reliable and flexible power supply, meet the increasing power consumption demand, and compared with the traditional generator set 30 equipped with only a single circuit breaker 21, there is no need for re-wiring, and the operation is simpler and safer.
[0027] Preferably, the circuit breaker 21 can be a molded case circuit breaker 21, an oil-minimum circuit breaker 21, or a vacuum circuit breaker 21, etc., and the output interface can be formed by simultaneously leading out two electrical interfaces with different current specifications at the electrical output end of the generator set 30.
[0028] Furthermore, it further includes a box body 20, and there are two chambers inside the box body 20, and the two circuit breakers 21 are respectively installed in the two chambers.
[0029] Specifically, during assembly, the two circuit breakers 21 can be respectively installed in two different chambers to isolate the circuit breakers 21 from the external environment through the box body 20, forming a relatively enclosed space, preventing external factors (such as dust, moisture, etc.) from damaging the circuit breakers 21, extending the service life of the equipment, and also reducing safety risks such as electric shock.
[0030] It should be noted that after the circuit breaker 21 is installed in the box body 20, the box body 20 can be placed into the installation cavity 11, and wires can be passed through by setting connection holes on the box body 20, so that after the two circuit breakers 21 are installed, the wires pass through the connection holes and extend out of the box body 20 to be connected to the output interface of the generator set 30.
[0031] In addition, the two chambers can be integrally formed inside the box body 20, or can be formed by setting a partition plate inside the box body 20 to divide the inside of the box body 20 into two chambers.
[0032] Furthermore, bakelite mounting plates 22 are respectively provided in the two chambers, and the two circuit breakers 21 are respectively installed on the two bakelite mounting plates 22.
[0033] Specifically, the circuit breaker 21, as a key device for protecting the circuit, may be exposed to various electrical interferences and potential risks in its working environment. Therefore, in this embodiment, a bakelite mounting plate 22 is provided in the chamber to mount the circuit breaker 21. Since the bakelite mounting plate 22 has good electrical insulation properties, it can effectively isolate the electrical contact between the circuit breaker 21 and the box body 20 or other metal components, prevent the occurrence of electric leakage and short - circuit accidents, provide a safe and stable electrical environment for the circuit breaker 21, and protect it from the impact of electrical faults.
[0034] It should be noted that during assembly, the two ends of the bakelite mounting plate 22 can be respectively connected to the two side walls of the chamber through connecting parts such as bolts or screws, or the bakelite mounting plate 22 can be snapped through structures such as slots or bayonets provided on the inner wall of the chamber. It can be set according to actual needs.
[0035] Furthermore, wiring copper bars 23 are respectively provided in the two chambers. The wiring copper bars 23 are electrically connected to the circuit breaker 21 and are used to conduct current.
[0036] Specifically, during assembly, the wiring copper bars 23 can be fixed above or on both sides of the circuit breaker 21, and a plurality of holes are provided on the wiring copper bars 23 to connect various wires with different specifications and quantities through the wiring copper bars 23, and different electrical devices are connected to meet different electrical connection requirements and conduct current to different devices.
[0037] Compared with the cumbersome connection method, using the wiring copper bars 23 is more convenient for wiring, reducing the complexity and time cost of manual operation. In addition, the design of the copper bars usually takes into account electrical safety and mechanical strength, and can effectively prevent the occurrence of electrical faults such as electric leakage and short - circuit, improving the safety of the entire circuit system.
[0038] Furthermore, it also includes a grounding copper bar 25. The grounding copper bar 25 is provided in one of the chambers. One end of the grounding copper bar 25 is electrically connected to the generator set 30, and the other end of the grounding copper bar 25 is connected to the grounding device.
[0039] Specifically, during assembly, the grounding copper bar 25 is connected to the key components (such as the stator base, the housing or the rotor shaft) of the generator set 30 through a connecting conductor, and then the grounding copper bar 25 is provided in one of the chambers of the box body 20 and connected to the external grounding electrode, so as to provide a low - impedance path for the generator set 30 through the grounding copper bar 25 to safely conduct the fault current or lightning strike current into the ground, thereby protecting the safety of the generator set 30 itself and other devices and personnel connected thereto.
[0040] Furthermore, it also includes insulators 24. Specifically, there are two insulators 24, which are respectively installed in the two chambers, and the insulators 24 are used for insulation.
[0041] Specifically, during assembly, the insulator 24 can be directly fixed to the circuit breaker 21 by bolts, crimping or other mechanical connection methods to ensure electrical insulation and mechanical support. Of course, the insulator 24 can also be indirectly electrically connected to the circuit breaker 21 through other conductors (such as the wiring copper bar 23 or wires), etc., to insulate the electrical environment inside the chamber through the insulator 24 and ensure sufficient insulation distance between the circuit breaker 21 and other conductive parts, thereby preventing current leakage and short - circuit faults.
[0042] Specifically, the insulator 24 can be made of insulating materials, such as porcelain insulators 24, glass insulators 24, composite insulators 24, etc.
[0043] Furthermore, the box body 20 further includes two box doors 26. The two box doors 26 are rotatably connected to both sides of the box body 20 and open or cover the two chambers when rotated.
[0044] Specifically, when the circuit breaker 21 needs to be repaired, the box door 26 can be rotated to open the chamber, which is convenient for users to repair the equipment inside the box body 20. After the repair, the box door 26 is rotated again to close the chamber to prevent external factors (such as dust, moisture, etc.) from damaging the circuit breaker 21, extend the service life of the equipment, and also reduce safety risks such as electric shock.
[0045] It should be noted that the box door 26 can be rotatably connected to the box body 20 through connecting parts such as hinges or rotating shafts.
[0046] Furthermore, it further includes a fan 12. The fan 12 is installed in the installation chamber 11 and conducts with the outside. The fan 12 is used to guide the air flow inside the installation chamber 11 to the outside.
[0047] Specifically, since the generator set 30, the circuit breaker 21 or other electrical equipment inside the installation chamber 11 generate heat during operation, which increases the heat inside the installation chamber 11. If it is not discharged in time, it may affect the normal operation of the equipment inside the installation chamber 11. Therefore, a fan 12 is also provided inside the installation chamber 11. During assembly, an air outlet can be set on the cabinet 10, and the fan 12 is installed at the air outlet to conduct with the external environment, so as to blow the heat inside the installation chamber 11 to the outside through the fan 12, dissipate heat from the equipment inside the installation chamber 11, avoid damaging the equipment inside the installation chamber 11 due to excessive heat inside the installation chamber 11, and indirectly extend the service life of the equipment.
[0048] Preferably, the fan 12 can be a exhaust fan 12 or a suction fan 12, etc.
[0049] More specifically, a plurality of heat dissipation holes 13 are provided on the cabinet body 10, and the plurality of heat dissipation holes 13 are communicated with the outside, so as to synchronously discharge the heat in the installation cavity 11 to the external environment through the plurality of heat dissipation holes 13, assist in dissipating heat from the installation cavity 11, and improve the heat dissipation efficiency inside the cabinet body 10.
