Description
Technical Field
[0001] The utility model relates to the technical field of grounding structures, in particular to an electric power cabinet and an electric control cabinet. Background Art
[0002] When power cabinets such as distribution cabinets, switch cabinets or electric control cabinets are working normally, the power cabinets need to be grounded. Most of the existing power cabinets are grounded by screw grounding or hard jumper grounding. Screw grounding is to connect the electronic components to the cabinet body with screws. Since the screws are conductive parts, the mechanical and electrical connection between the electronic components and the cabinet body is realized. Therefore, the grounding of the power cabinet is realized by connecting the grounding wire to the cabinet body. Hard jumper grounding is that a hard jumper is fixed on the electronic component itself as a grounding wire, and the grounding protection of the electronic component is realized by directly connecting the grounding wire to the grounding device. Among them, when testing the electronic components in the power cabinet, the grounding of the power cabinet needs to be cancelled to ensure the smooth progress of the test.
[0003] However, in the process of realizing the utility model, the inventors found that there are at least the following technical problems in the prior art: for example, when testing electronic components in an electric power cabinet that adopts a screw grounding method, it is necessary to first disassemble the cabinet to expose the electronic components, and then remove the screws to remove the electronic components from the cabinet, take out the electronic components and connect them to the test equipment for testing, and after the test, the electronic components need to be reinstalled into the cabinet, and then the cabinet needs to be assembled. The above operations are complicated and tedious, and the disassembly and assembly of electronic components will inevitably cause damage to the electronic components; when testing electronic components in an electric power cabinet that adopts a hard jumper grounding method, the hard jumper serving as the grounding wire can only be destructively cut, and this process is irreversible. The electric power cabinet cannot be restored to ground after the test.
[0004] Therefore, the present application provides a new power cabinet and electric control cabinet to address the above problems. Utility Model Content
[0005] The utility model aims to provide an electric power cabinet, so as to at least alleviate the technical problems existing in the prior art that the test operation of electronic components in the electric power cabinet is complicated or the grounding cannot be restored after the test.
[0006] The utility model also aims to provide an electric control cabinet to further alleviate the technical problems existing in the prior art of cumbersome operation of testing electronic components in the power cabinet or inability to restore grounding after testing.
[0007] Based on the above first purpose, the utility model provides a power cabinet, which includes a cabinet body, electronic components and a grounding terminal;
[0008] The electronic components are arranged inside the cabinet and are electrically insulated from the cabinet; the grounding terminal is arranged outside the cabinet, and the electronic components are electrically connected to the grounding terminal.
[0009] Furthermore, the grounding terminal is mechanically connected to the cabinet, and / or the grounding terminal is electrically connected to the cabinet.
[0010] Furthermore, the grounding terminal can be pluggably connected or threadedly connected to an external grounding wire.
[0011] Furthermore, the cabinet is provided with a wire hole;
[0012] The electric power cabinet further comprises a lead-out line, one end of which is electrically connected to the electronic component, and the other end of which passes through the lead-out hole and is electrically connected to the ground terminal.
[0013] Furthermore, the lead-out line is detachably connected to the electronic component and is detachably connected to the ground terminal.
[0014] Furthermore, both ends of the lead-out line are provided with wiring cards for detachably connecting with the electronic components and the ground terminal.
[0015] Furthermore, the electronic components are connected to the cabinet via an insulating member, and the insulating member allows a gap to exist between the electronic components and the cabinet.
[0016] Furthermore, the electronic components are connected to the cabinet through insulating parts, and a plurality of insulating parts are provided, and the plurality of insulating parts are arranged at intervals.
[0017] Furthermore, the cabinet includes a side wall and a top plate and a bottom plate respectively arranged at two ends of the side wall, and the side wall, the top plate and the bottom plate together form an inner cavity for accommodating the electronic components;
[0018] Wherein, the side wall includes a first plate and a second plate which are arranged opposite to each other, one end of the bottom plate is pivotally connected to the first plate, and the other end is detachably connected to the second plate.

[0020] The power cabinet is, for example, a distribution cabinet, a switch cabinet or an electric control cabinet, and the electronic components are electronic components that need to be tested, such as a control board, a varistor or a gas discharge tube.
[0021] With such an arrangement, when grounding protection of electronic components is required, the grounding wire can be connected to the grounding terminal. At this time, since the electronic components are electrically connected to the grounding terminal, grounding protection of the electronic components in the power cabinet is achieved.
[0022] When it is necessary to test the electronic components in the power cabinet, it is only necessary to remove the grounding wire from the grounding terminal to cancel the grounding of the electronic components in the power cabinet. At this time, since the electronic components are electrically insulated from the cabinet, the electronic components can be directly tested without removing the electronic components from the cabinet. Therefore, there is no need to disassemble the cabinet, and there is no need to reinstall the electronic components into the cabinet after testing, and the step of assembling the cabinet is omitted, thereby making the operation of electronic component testing simple, convenient, and time-saving and labor-saving.
[0023] In addition, after the test, the grounding wire can be reconnected to the grounding terminal to restore the grounding protection of the electronic components.

[0039] Embodiment 1
[0040] See also Figure 1 and Figure 2 The present embodiment provides an electric power cabinet, which includes a cabinet body 1, electronic components 2 and a grounding terminal 3; the electronic components 2 are arranged in the cabinet body 1 and are electrically insulated from the cabinet body 1; the grounding terminal 3 is arranged outside the cabinet body 1, and the electronic components 2 are electrically connected to the grounding terminal 3.
[0041] It should be noted that the power cabinet is, for example, a distribution cabinet, a switch cabinet or an electric control cabinet, and the electronic components 2 are electronic components 2 to be tested, for example, the electronic components 2 are control boards, varistors or gas discharge tubes.
[0042] With such an arrangement, when grounding protection of the electronic components 2 is required, the grounding wire can be connected to the grounding terminal 3. At this time, since the electronic components 2 are electrically connected to the grounding terminal 3, grounding protection of the electronic components 2 in the power cabinet is achieved.
[0043] When it is necessary to test the electronic components 2 in the power cabinet, it is only necessary to remove the grounding wire from the grounding terminal 3 to cancel the grounding of the electronic components 2 in the power cabinet. At this time, since the electronic components 2 are electrically insulated from the cabinet 1, the electronic components 2 can be directly tested without removing the electronic components 2 from the cabinet 1. Therefore, there is no need to disassemble the cabinet 1, and there is no need to reinstall the electronic components 2 into the cabinet 1 after the test. The step of assembling the cabinet 1 is omitted, thereby making the operation of testing the electronic components 2 simple, convenient, and time-saving and labor-saving.
[0044] In addition, after the test, the grounding wire can be reconnected to the grounding terminal 3 to restore the grounding protection of the electronic component 2. Since the grounding terminal 3 is arranged outside the cabinet 1, the grounding connection of the electronic component 2 is led out to a convenient operation location. Therefore, it is more convenient to connect the grounding wire to the grounding terminal 3 and remove the grounding wire from the grounding terminal 3, which alleviates the technical problems in the prior art of cumbersome operation of testing electronic components 2 in power cabinets or inability to restore grounding after testing.
[0045] Optionally, see Figure 2 In this embodiment, the ground terminal 3 is mechanically connected to the cabinet 1, or the ground terminal 3 is electrically connected to the cabinet 1, or the ground terminal 3 is mechanically and electrically connected to the cabinet 1.
[0046] With such a setting, when grounding protection of the power cabinet is required, the grounding wire can be connected to the grounding terminal 3. At this time, since the electronic components 2 are electrically connected to the grounding terminal 3, and the grounding terminal 3 is electrically connected to the cabinet body 1, the grounding protection of the electronic components 2 in the power cabinet and the grounding protection of the outer casing of the power cabinet are achieved, thereby ensuring the safe use of the power cabinet.
[0047] When the electronic components 2 in the power cabinet need to be tested, the grounding wire only needs to be removed from the grounding terminal 3, so that the electronic components 2 in the power cabinet and the shell of the power cabinet are both ungrounded, which facilitates the smooth progress of the test.
[0048] In addition, the grounding terminal 3 is mechanically connected to the cabinet 1 , making it more convenient to connect the grounding wire to the grounding terminal 3 and to remove the grounding wire from the grounding terminal 3 .
[0049] Optionally, the ground terminal 3 is pluggably connected or threadedly connected to an external ground wire.
[0050] Specifically, when the ground terminal 3 and the ground wire are pluggable, if the ground wire needs to be connected to the ground terminal 3, it is only necessary to insert the ground wire into the ground terminal 3, and if the ground wire needs to be removed from the ground terminal 3, it is only necessary to pull the ground wire out of the ground terminal 3. When the ground terminal 3 and the ground wire are threadedly connected, if the ground wire needs to be connected to the ground terminal 3, it is only necessary to screw the ground wire into the ground terminal 3, and if the ground wire needs to be removed from the ground terminal 3, it is only necessary to screw the ground wire out of the ground terminal 3.
[0051] Therefore, such a configuration makes the operation of connecting the ground wire to the ground terminal 3 and removing the ground wire from the ground terminal 3 simpler and more convenient, further alleviating the technical problem of cumbersome testing operation of electronic components 2 in power cabinets existing in the prior art.
[0052] Optionally, see Figure 2 In this embodiment, the cabinet body 1 is provided with a wire hole 11; the power cabinet also includes a lead-out wire 4, one end of which is electrically connected to the electronic component 2, and the other end passes through the wire hole 11 and is electrically connected to the ground terminal 3.
[0053] Such an arrangement realizes the electrical connection between the electronic component 2 disposed in the cabinet 1 and the ground terminal 3 disposed outside the cabinet 1 .
[0054] The ground connection of the electronic component 2 is led out to a convenient operation location outside the cabinet 1 through the lead-out line 4, which increases the flexibility of the test and has operability and repeatability.
[0055] Optionally, in this embodiment, the lead wire 4 is detachably connected to the electronic component 2 and is detachably connected to the ground terminal 3. Such an arrangement facilitates the disassembly of the electronic component 2 and the lead wire 4.
[0056] For example, both ends of the lead-out line 4 are provided with wiring cards for detachably connecting with the electronic component 2 and the ground terminal 3 .
[0057] With such an arrangement, when assembling the power cabinet, one only needs to clamp the wiring clips at both ends of the lead-out line 4 on the electronic component 2 and the grounding terminal 3 respectively. When disassembling the power cabinet, one only needs to remove the wiring clips at both ends of the lead-out line 4 from the electronic component 2 and the grounding terminal 3 respectively. The operation is simple, convenient, and saves time and effort.
[0058] Optionally, in this embodiment, the electronic component 2 is connected to the cabinet 1 through an insulating member.
[0059] Such a configuration realizes that the electronic component 2 is mechanically connected to the cabinet 1 and is electrically insulated from the cabinet 1. Therefore, the electronic component 2 can be directly tested while remaining in the state of being mechanically connected to the cabinet 1, without removing the electronic component 2 from the cabinet 1, thereby ensuring the reliability of the installation of the original electronic component 2 and preventing the electronic component 2 from being damaged due to transportation and other reasons.
[0060] For example, see Figure 1 The electronic components 2 are connected to the cabinet 1 through the insulating column 5.
[0061] Optionally, see Figure 1 In this embodiment, a plurality of insulating columns 5 are provided, and the plurality of insulating columns 5 are arranged at intervals. Such an arrangement enables the electronic components 2 to be installed in the cabinet 1 more firmly and reliably.
[0062] Optionally, the insulating member allows a gap to exist between the electronic component 2 and the cabinet 1 . Such an arrangement further ensures the electrical insulation relationship between the electronic component 2 and the cabinet 1 .
[0063] Optionally, see Figure 1 In this embodiment, the cabinet includes a side wall and a top plate and a bottom plate 14 respectively arranged at both ends of the side wall. The side wall, the top plate and the bottom plate 14 together form an inner cavity for accommodating the electronic components 2. The side wall includes a first plate 12 and a second plate 13 arranged opposite to each other. One end of the bottom plate 14 is pivotally connected to the first plate 12, and the other end is detachably connected to the second plate 13. For example, one end of the bottom plate 14 away from the first plate 12 is bent to form a connecting portion, and the connecting portion is detachably connected to the second plate through a threaded connector 15.
[0064] With such an arrangement, when the power cabinet needs to be maintained, it is only necessary to remove one end of the bottom plate 14 from the second plate 13 and then rotate the other end of the bottom plate 14 relative to the first plate 12. The operation is simple and convenient, and saves time and effort.
