[0002] In the power transmission and transformation system, low-voltage distribution cabinets (referred to as "low-voltage cabinets") are placed side by side. According to the different cabinet types, low-voltage distribution cabinets can be divided into incoming line cabinets, busbar cabinets, feeder cabinets, variable frequency soft start cabinets, etc. Among them, the feeder cabinet usually adopts a drawer structure or a fixed partition structure. When the drawer structure is adopted, refer to Figure 1 The drawer part 200 can be divided into a fixed part 210 (i.e., integrated with the cabinet frame) and a movable part 220 (i.e., the drawer unit can be pulled out and separated). The advantages of this structure are: first, the entire system does not lose power. If a drawer unit fails, the drawer can be pulled out for maintenance without affecting the operation of other equipment. Second, the interchangeability of the drawers is guaranteed. When a single drawer fails, it can be replaced with a spare drawer in the first place to ensure the normal operation of the equipment.

[0049] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Example

[0050] like Figures 1 to 13 As shown, the low-voltage cabinet drawer 100 provided in some embodiments of the present invention includes: a fixed cabinet body 110 , a movable cabinet body 120 , a first movable member 130 and a second movable member 140 .

[0051] The fixed cabinet 110 is fixedly arranged at a corresponding position of the frame of the low-voltage cabinet, and is provided with a receiving cavity 111 for placing at least a part of the movable cabinet 120, on which a plurality of wiring terminals are arranged, which are not shown in the drawings. The movable cabinet 120 is used to install electronic components loaded in the circuit to control the normal operation of the circuit, and the movable cabinet 120 is slidably connected to the fixed cabinet 110 along the first straight line direction L1 so that the movable cabinet 120 has at least a first position and a second position relative to the fixed cabinet 110. When the movable cabinet 120 is in the first position, one end of the movable cabinet 120 along the first straight line direction L1 is inserted into the receiving cavity 111 along the first straight line direction L1, so as to provide protection for the electronic components in the movable cabinet 120 through the fixed cabinet 110 and the frame of the low-voltage cabinet, and the electrical cabinet as a whole and its frame are not shown in the drawings. When the movable cabinet 120 is in the second position, most of the movable cabinet 120 is located outside the accommodation space, so as to perform operations such as repairing and wiring the electronic components or replacing the movable cabinet 120 .

[0052] In order to avoid circuit failure caused by mixing low-load movable cabinets 120 and high-load movable cabinets 120 when replacing the movable cabinet 120, in the present utility model, one of the first movable member 130 and the second movable member 140 is provided with a plurality of protrusions A extending along the first linear direction L1, and the other is provided with a plurality of through grooves B extending along the first linear direction L1. The accompanying drawings only show the situation in which the through grooves B are provided on the first movable member 130 and the protrusions A are provided on the second movable member 140. When the movable cabinet 120 is in the first position, the protrusions A are embedded in the through grooves B and the first movable member 130 and the second movable member 140 form a sliding connection along the first linear direction L1, that is, in the process in which the movable cabinet 120 slides along the first linear direction L1 and is inserted into the accommodating cavity 111, the protrusions A can at least be inserted into the through grooves B. At the same time, the first movable member 130 is slidably connected to the movable cabinet 120 along the second linear direction L2 perpendicular to the first linear direction L1. The second movable member 140 is slidably connected to the fixed cabinet 110 along the second linear direction L2.

[0053] By adopting the above scheme, the relative positions of the first movable member 130 and the movable cabinet 120, and the second movable member 140 and the fixed cabinet 110 on each low-voltage cabinet drawer 100 can be adjusted by adjusting the first movable member 130 and the second movable member 140. In this way, the relative positions of the first movable members 130 on the movable cabinet 120 and the second movable member 140 on the fixed cabinet 110 of multiple low-voltage cabinet drawers 100 with matching circuit load conditions can be defined to be the same, and the relative positions of the second movable members 140 on the fixed cabinet 110 can be the same, so that the movable cabinets 120 with matching load conditions can be interchanged. Correspondingly, the relative positions of the first movable members 130 on the movable cabinet 120 and the second movable members 140 on the fixed cabinet 110 of multiple low-voltage cabinet drawers 100 with unmatched circuit load conditions can be defined to be different, so that the movable cabinets 120 with matching load conditions cannot be interchanged, which prevents the misplacement of the movable cabinet 120, thereby avoiding circuit failures caused by misplacement of the movable cabinet 120. The positions of the first movable part 130 and the second movable part 140 on the low-voltage cabinet drawer 100 are flexibly adjustable, so the number of low-voltage cabinet drawers 100 with the same load and interchangeable on the low-voltage cabinet can be flexibly set according to usage requirements, which is convenient for maintenance work.

[0054] In some embodiments, the low-voltage cabinet drawer 100 further includes: a first fixing member 150 and a second fixing member. The first fixing member 150 is fixedly connected to the movable cabinet 120. The first fixing member 150 is provided with a first slide groove 151 extending along the second straight line direction L2. The first movable member 130 is at least partially inserted into the first slide groove 151 to limit the sliding direction of the first movable member 130. The second fixing member is fixedly connected to the fixed cabinet 110. The second fixing member is provided with a second slide groove extending along the second straight line direction L2. The first movable member 130 is at least partially inserted into the second slide groove to limit the sliding direction of the second movable member 140. The above scheme realizes the sliding connection between the first movable member 130 and the movable cabinet 120, and the sliding connection between the second movable member and the fixed cabinet 110.

[0055] The fixing method of the first fixing member 150 on the movable cabinet 120 and the fixing method of the second fixing member on the movable cabinet 120 can be, for example, screw fixing, snap-on connection, etc., which are not limited here.

[0056] In an optional implementation scheme, the low-voltage cabinet drawer 100 further includes: a first magnet 160 and a second magnet. The first magnet 160 is fixedly connected to the first fixing member 150 so that the first fixing member 150 is mounted to the movable cabinet 120 by magnetic adsorption. The second magnet is fixedly connected to the second fixing member so that the second fixing member is mounted to the fixed cabinet 110 by magnetic adsorption. With this solution, compared with conventional screw fixing methods, the first fixing member 150 and the second fixing member are more convenient to install and remove, which can facilitate the assembly work.

[0057] In some embodiments, the first fixing member 150 is provided with a plurality of first columns 152. The movable cabinet 120 is provided with a plurality of first through-holes 121. The first column 152 is embedded in the first through-hole 121. The second fixing member is provided with a plurality of second columns. The movable cabinet 120 is provided with a plurality of second through-holes. The second column is embedded in the second through-hole. That is, on the basis of setting the first magnet 160 and the second magnet, the first column 152 is used in conjunction with the first through-hole 121, and the second column is used in conjunction with the second through-hole to further limit the first fixing member 150 and the second fixing member, so that the two can be stably used on the low-voltage cabinet drawer 100.

[0058] In some embodiments, the first movable member 130 includes: a first matching portion 131 and a first connecting portion 132. Among them, one of the through groove B and the protrusion A is formed in the first connecting portion 132, and the first connecting portion 132 can extend out of the first slide groove 151 so as to match with the protrusion A / through groove B on the second movable member 140. The first matching portion 131 is slidably arranged in the first slide groove 151. The first matching portion 131 is provided with at least one positioning groove 133, and the positioning groove 133 can be, for example, a rectangular groove. The inner wall of the first fixed member 150 forming the slide groove is linearly distributed along the second linear direction L2 and formed with a plurality of positioning teeth 153, and the positioning teeth 153 can be, for example, a rectangular protrusion protruding from the inner wall of the first fixed member 150. The positioning groove 133 is engaged with the positioning teeth 153 to limit the first movable member 130 from sliding along the second linear direction L2. The first movable member 130 is slidably connected with the first fixed member 150 along the third linear direction L3 perpendicular to the second linear direction L2.

[0059] It is also recorded in the above technical solution that the first movable member 130 can be moved along the third linear direction L3 to disengage the positioning groove 133 from the positioning tooth 153, and then the first movable member 130 can be moved along the second linear direction L2 to engage the positioning groove 133 with different positioning teeth 153, thereby adjusting the position of the first movable member 130 relative to the first fixed member 150 in the second linear direction L2, that is, adjusting the relative position of the first movable member 130 and the movable cabinet 120. At this time, it can be further limited that the first movable member 130 is made of a material that can be attracted by a magnet, such as the first movable member 130 is made of iron, so that after adjusting the relative position of the first movable member 130 and the movable cabinet 120, the first movable member 130 is stably installed on the first fixed member 150 by magnetic force.

[0060] In a more specific implementation scheme, the low-voltage cabinet drawer 100 also includes: a third magnet 134 and a connecting rod 135. Among them, the third magnet 134 is located between the first magnet 160 and the first connecting portion 132. The opposite ends of the third magnet 134 have a first magnetic pole and a second magnetic pole. The first magnetic pole is opposite to the first magnet 160. The second magnetic pole is the same as the first magnet 160. The third magnet 134 is rotatably connected to the first connecting portion 132 so that the third magnet 134 has at least a first rotation position and a second rotation position relative to the first movable member 130. When the third magnet 134 is located in the first rotation position, the first magnetic pole is located between the second magnetic pole and the first magnet 160 so that the first magnet 160 and the third magnet 134 attract each other. When the third magnet 134 is located in the first rotation position, the second magnetic pole is located between the first magnetic pole and the first magnet 160 so that the first magnet 160 and the third magnet 134 repel each other. One end of the connecting rod 135 is fixedly connected to the third magnet 134 , and the other end of the connecting rod 135 passes through the oval hole provided on the first connecting portion 132 , so that the connecting rod 135 can slide and rotate relative to the first connecting portion 132 .

[0061] By adopting the above scheme, when the position of the first movable member 130 needs to be adjusted, the third magnet 134 can be rotated to the first rotation position by rotating the connecting rod 135. At this time, the positioning groove 133 and the positioning tooth 153 are conveniently disengaged under the action of magnetic force. Then, the connecting rod 135 can be pulled to move the third magnet 134 and the first movable member 130 relative to the first fixed member 150, so as to adjust the relative position of the first movable member 130 and the movable cabinet 120. Then, the third magnet 134 can be rotated to the second rotation position by rotating the connecting rod 135 again. Under the action of magnetic force, the positioning groove 133 and the positioning tooth 153 are engaged again, so that the first movable member 130 is positioned on the first fixed member 150. Compared with the method of directly pulling the first movable member 130 to adjust its position, this scheme is more convenient and labor-saving.

[0062] In another optional embodiment, the low voltage cabinet drawer 100 further includes: a first screw 170. The first screw 170 is rotatably connected to the first fixing member 150. The first screw 170 is inserted into the first slide groove 151 and is threadedly connected to the first movable member 130. At this time, the relative position between the first movable member 130 and the movable cabinet body 120 can be adjusted by rotating the first screw 170.

[0063] In a specific implementation scheme, an identification line 180 may also be provided on the first fixing member 150 and the second fixing member to mark the specific positions between the first movable member 130 and the first fixing member 150, and between the second movable member 140 and the second fixing member, so as to facilitate the operator to adjust the specific positions of the first movable member 130 and the second movable member 140 on each low-voltage cabinet drawer 100 with matching load conditions, thereby allowing the low-voltage cabinet drawers 100 with matching load conditions to be interchangeable.

[0064] The above partial solutions specifically describe the matching mode and connection relationship between the first movable member 130 and the first fixed member 150. It can be understood that the second movable member 140 and the second fixed member can also refer to the above various embodiments, so that the second matching part, the second connecting part, the third magnet 134, etc. with similar functions and structures to the first matching part 131, the first connecting part 132, the third magnet 134, etc. are set on the second connecting member and the second fixed member. These structures are not shown in the drawings, and those skilled in the art can flexibly select and set the corresponding structures according to actual conditions, and will not be repeated here.

[0065] In the present invention, the first movable member 130 can be arranged on the side or bottom of the movable cabinet 120, preferably on the side of the movable cabinet 120, to facilitate user operation. Correspondingly, the second movable member 140 can be arranged on the side or bottom of the fixed cabinet 110, preferably on the side of the fixed cabinet 110.

[0066] In some embodiments, the low-voltage cabinet drawer 100 further includes: rollers 190. The rollers 190 are rotatably connected to both sides of the movable cabinet 120. When the movable cabinet 120 is located at the first position, the rollers 190 are located in the accommodating cavity 111 and contact the fixed cabinet 110 to form the inner wall of the accommodating cavity 111, so as to provide support for the movable cabinet 120 and reduce the sliding resistance during the sliding of the movable cabinet 120 relative to the fixed cabinet 110.

[0067] In some embodiments, when the movable cabinet 120 is located at the second position, the roller 190 is located outside the accommodating cavity 111. In the process of the movable cabinet 120 moving from the second position to the first position, the roller 190 first enters the accommodating cavity 111 and contacts the inner wall of the fixed cabinet 110, and then the protrusion A is inserted into the through groove B. That is, in the process of the movable cabinet 120 being inserted into the accommodating cavity 111, the roller 190 first contacts the fixed cabinet 110 and provides support for the fixed cabinet 110, and then the protrusion A is matched with the through groove B. This installation method can use the roller 190 to pre-position the protrusion and the groove, so that the two can be embedded.

[0068] In some embodiments, the portion forming the through groove B and / or the two ends of the protrusion A along the first straight line direction L1 are provided with inclined guide surfaces C, and the inclined guide surface C can be a plane, an arc surface, a curved surface, etc. Figure 6 The inclined guide surfaces C at both ends of the groove B make the width of the two ends of the groove B larger than the middle part, and the inclined guide surfaces C at both ends of the protrusion A make the width of the two ends of the protrusion A smaller than the middle part, so that when the movable cabinet 120 moves relative to the fixed cabinet 110, the protrusion A and the groove B can be smoothly embedded.

[0069] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
