Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electrical cabinets, in particular to a drawer-type low-voltage power distribution cabinet. Background Art

[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 Each drawer part 200 of the drawer-type low-voltage power distribution cabinet 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 is powered on. 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.

[0003] In the drawer part 200, electronic components such as wiring terminals, inverters, switching power supplies, circuit boards, etc. are fixedly arranged on the movable part 220. These electronic components need to be electrically connected to the external circuit through the wiring between the fixed part 210 and the movable part 220. Specifically, wiring terminals are often arranged on the end of the movable part 220 inserted into the fixed part, and power lines and signal lines are connected through these wiring terminals. These power lines and signal lines are then passed through the movable part and further connected from the fixed part 210 to the external circuit, or electrically connected to the lines of other drawer parts 200.

[0004] When the existing drawer-type low-voltage distribution cabinet is in use, a low-voltage distribution cabinet needs to be installed with as many unit drawers as possible, which causes the internal space of the drawer unit to be compressed, and the installation space of electronic components is compact, which brings difficulties to the internal wiring and other processes. Line workers are often scratched by the drawer sheet metal, wire ends, etc. when they are walking drawers. Most of the existing drawer structures in the market are cumbersome to install, have many parts, and need to be operated in a small space. The production efficiency is low, it is inconvenient for users to manage the wires, and there are many inconveniences during maintenance. Users are easily injured by bumping into the internal structure of the drawer. Therefore, it is necessary to improve the drawer-type low-voltage distribution cabinet based on the actual needs of convenient replacement of drawer cabinets while avoiding the misplacement of moving parts during replacement.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] like Figures 2 to 11 As shown, some embodiments of the present invention provide a drawer-type low-voltage power distribution cabinet 100, comprising: a fixed cabinet body 110 and a movable cabinet body 120; wherein the movable cabinet body 120 comprises: an operating portion 121, a supporting portion 122, a side body portion 123 and an installation portion 124.

[0046] Specifically, 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. The movable cabinet 120 is used to install the electronic components loaded in the circuit to control the normal operation of the circuit. The movable cabinet 120 is slidably connected to the fixed cabinet 110 along the first linear 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 linear direction L1 is inserted into the receiving cavity 111 along the first linear direction L1, so that the electronic components in the movable cabinet 120 are protected by the frame of the low-voltage electrical cabinet and the fixed cabinet 110. The low-voltage 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 receiving space, so as to perform maintenance and wiring of the electronic components, or replace the movable cabinet 120.

[0047] The operating part 121 is arranged on a side of the movable cabinet 120 away from the fixed cabinet 110 along the first straight direction L1, and is used for being touched by the user, and the movable cabinet 120 is moved relative to the fixed cabinet 110 by moving the operating part 121. The operating part 121 can be arranged outside the accommodating cavity 111, for example. The supporting part 122 is arranged on a side of the operating part 121 close to the fixed cabinet 110 along the first straight direction L1, and is located in the accommodating cavity 111, and is fixedly arranged or integrally formed at the bottom of the supporting part 122. A side body part 123 is respectively arranged at both ends of the supporting part 122 along the second straight direction L2 perpendicular to the first straight direction L1, and the side body part 123 is fixedly connected or integrally formed with the supporting part 122. The mounting part 124 is located between the two opposite side body parts 123, and is located at one end of the supporting part 122 away from the operating part 121. For example, the mounting part 124 and the side body part 123 are both located above the supporting part 122. The operating portion 121 , the supporting portion 122 , the side portion 123 and the mounting portion 124 are mutually surrounded to form an installation space 120 a , and the installation space 120 a is used to place electronic components such as a switching power supply, a circuit board and the like.

[0048] Generally speaking, it is necessary to lay lines on the installation part 124, and these lines are placed in the fixed cabinet 110 after passing through the movable cabinet 120, and then the lines are electrically connected to the external circuit of the low-voltage distribution cabinet, or electrically connected to other parts of the same low-voltage distribution cabinet. In order to facilitate the user to organize the lines and maintain, the utility model defines that the wall surface of the side body 123 forming the installation space 120a is provided with a first slide rail 123a extending along the first straight line direction L1. The support part 122 is provided with a first slide groove 24a. The first slide rail 123a is inserted into the first slide groove 24a so that the first slide rail 123a is slidably connected to the support part 122 along the first straight line direction L1.

[0049] By adopting the above scheme, the installation part 124 can be moved to a position close to the operating part 121 along the first straight direction L1 during wiring management and maintenance, so that the user can access the lines on the installation part 124 and perform operations, thereby eliminating the need for the user to operate in the relatively closed space enclosed by the movable cabinet 120 and the fixed cabinet 110, thereby facilitating wiring management and maintenance.

[0050] In some embodiments, a latch 124b is slidably provided on the mounting portion 124. A through hole 123b is provided on the side body portion 123. At least a portion of the latch 124b is inserted into the through hole 123b, so that the latch 124b is inserted between the mounting portion 124 and the side body portion 123 and restricts the mounting portion 124 from sliding relative to the side body portion 123. That is, after the latch 124b is inserted into the through hole 123b, the latch 124b is used to prevent the mounting portion 124 from sliding along the first straight line direction L1, thereby locking the mounting portion 124 at one end of the side body portion 123 away from the operating portion 121, so that the mounting portion 124 remains stable in the fixed cabinet 110 when the low-voltage power distribution cabinet is in normal use, thereby ensuring stable line connection.

[0051] In a further optional embodiment, at least a portion of the latch 124b extends into the installation space 120a along the second straight line direction L2. A first spring 125 is provided between the side body 123 and the latch 124b. The first spring 125 biases the latch 124b so that the latch 124b tends to be inserted into the through hole 123b. Using the first spring 125 to apply pressure to the latch 124b can prevent the latch 124b from being disengaged from the through hole 123b due to the shaking of the distribution cabinet or other reasons during normal use of the low-voltage distribution cabinet, further ensuring stable line connection. At the same time, during assembly and maintenance, in the process of moving the installation portion 124 to the end of the side body 123 away from the operating portion 121, the elastic force of the first spring 125 drives the latch 124b to automatically insert into the through hole 123b, and there is no need for manual operation in a relatively closed and narrow space to complete the locking of the installation portion 124, which is convenient for users to operate.

[0052] In some embodiments, a second slide groove 124c is provided on the side body portion 123. A slide 126 is provided at the second slide rail 126a of the side body portion 123. The slide 126 is provided with a second slide rail 126a, and the second slide groove 124c can be fixed to the side body portion 123 by welding, for example, and is formed by a strip metal piece and the surface of the side body portion 123, and the second slide rail 126a can be, for example, a part located at the end of the slide 126. The second slide rail 126a is inserted into the second slide groove 124c so that the slide 126 and the mounting portion 124 form a sliding connection. A fixed wiring terminal 127 is fixedly provided on the slide 126, and the fixed wiring terminal 127 can be used for wiring, and is further electrically connected to each electronic component in the installation space 120a through wiring, that is, the purpose of connecting the electronic components in the installation space 120a with the circuit outside the installation space 120a can be achieved through the fixed wiring terminal 127. One end of the second sliding groove 124c is open, so that the second sliding rail 126a can be moved out of the second sliding groove 124c from the open end of the second sliding groove 124c.

[0053] In this way, the connection terminal can be conveniently removed from the mounting portion 124 together with the slide 126, or installed on the mounting portion 124 together with the slide 126, which further facilitates the user to organize the wires and perform maintenance.

[0054] In a further optional embodiment, a movable terminal 128 is slidably provided on the slide 126, and the sliding connection method can be, for example: a T-shaped slot 128a is provided on the movable terminal 128, and only one end of the T-shaped slot 128a passes through the movable terminal 128, and a T-shaped protrusion 126b is correspondingly provided on the slide 126, and the T-shaped protrusion 126b is embedded in the T-shaped slot 128a and slides in the T-shaped slot 128a, thereby realizing the sliding connection between the slide 126 and the movable terminal 128. A plurality of connecting posts 128b are provided on the movable terminal 128. The connecting posts 128b are electrically connected to the fixed terminal 127, for example, the wire connected to the fixed terminal 127 is fixed to the connecting posts 128b by screws on the movable terminal 128. A plurality of connecting sockets 124d are provided on the side body 123. Metal contacts are provided in the connecting sockets 124d. The connecting post 128 b is inserted into the connecting hole 124 d and contacts the metal contact piece, so that the metal contact piece is electrically connected to the fixed connecting terminal 127 through the connecting post 128 b .

[0055] By adopting the above scheme, the metal contact piece can be further connected to the circuit outside the installation space 120a. When maintenance or wiring is required, the connection terminal can be slid to disconnect it from the metal contact piece, so that the circuit connected to the movable connection terminal in the installation space 120a is disconnected from the corresponding circuit outside the installation space 120a, and then the slide 126 can be removed from the installation part 124. This operation method can conveniently disconnect the connection with the circuit outside the installation space 120a and then perform maintenance or wiring on each part of the circuit in the installation space 120a separately, and the fixed connection terminal 127 and the movable connection terminal 128 can be moved to a position close to the operation part 121 for operation, thereby expanding the user's operation space and further facilitating the user's operation.

[0056] In some embodiments, the movable cabinet 120 further includes: a plurality of electrical installation sheets 130. The electrical installation sheets 130 are located in the installation space 120a and are arranged on the support portion 122. The electrical installation sheets 130 can be used to fix and install various electronic components, so that each electronic component is arranged in the installation space 120a in different areas. Those skilled in the art can determine the connection form between the electronic components and the electrical installation sheets 130 according to the specific types of the electronic components, which will not be described in detail here.

[0057] Specifically, the wall surface of the support portion 122 forming the installation space 120a is provided with a positioning portion 122a. The positioning portion 122a is provided with a slot 122b into which the power supply installation piece 130 is inserted. The electrical installation piece 130 is slidably arranged in the slot 122b, and the positioning portion 122a can be used to limit the installation of the electrical installation piece 130 and the electronic components arranged on the electrical installation piece 130.

[0058] More specifically, the inner wall of the positioning portion 122a forming the slot 122b is protruded and provided with a limiting portion 122c. The electrical installation piece 130 is located between the limiting portion 122c and the wall surface of the support portion 122 forming the installation space 120a to limit the sliding direction of the electrical installation piece 130 relative to the positioning portion 122a, that is, by providing the limiting portion 122c, the electrical installation piece 130 can be prevented from being separated from the positioning portion 122a. The electrical installation piece 130 is provided with a notch 131 that cooperates with the limiting portion 122c. When the electrical installation piece 130 slides to the point where the notch 131 is directly opposite to the limiting portion 122c, the limiting portion 122c releases the restriction on the sliding direction of the electrical installation piece 130. In this way, when the low-voltage distribution cabinet is normally used, the limiting portion 122c can be used to install the electrical installation piece 130 on the support portion 122. When maintenance or wiring is required, the movable electrical installation sheet 130 can be made so that the notch 131 is directly opposite to the limiting portion 122c, and the electrical installation sheet 130 can be moved to be separated from the positioning portion 122a, so that the electronic components on the electrical installation sheet 130 can be removed from the support portion 122. In addition, this installation method is used in conjunction with the fixed wiring terminal 127 and the movable wiring terminal 128, so that one electrical installation sheet 130 can correspond to at least one sliding sheet 126, thereby realizing the modular installation of electronic components and their matching circuits, facilitating the layout of the electronic components and their corresponding circuits in the installation space 120a, as well as the assembly and maintenance work.

[0059] In a further embodiment, the movable cabinet 120 further includes: a supporting plate 140 and a second spring 150. The supporting plate 140 is slidably disposed in the slot 122b and is located between the wall of the support portion 122 forming the installation space 120a and the limiting portion 122c. The supporting portion 122 contacts the supporting plate 140. The second spring 150 is disposed between the supporting plate 140 and the supporting portion 122 to bias the supporting plate 140 so that it tends to approach the limiting portion 122c. At this time, it can be further limited that the surface of the supporting plate 140 and the electrical installation plate 130 in contact with each other and / or the surface of the electrical installation plate 130 and the limiting portion 122c in contact with each other are roughened, for example, by increasing the surface roughness on the contact surface and setting a friction plate such as gauze to increase the friction resistance of the contact surface.

[0060] By adopting the above scheme, the elastic force of the second spring 150 is utilized to stabilize the electrical appliance mounting plate 130 on the support portion 122 when the low-voltage power distribution cabinet is in use. During maintenance, the electrical appliance mounting plate 130 can be pressed to separate from the limiting portion 122c, and then the electrical appliance mounting plate 130 is slid so that the notch 131 faces the limiting portion 122c. Under the elastic force of the second spring 150, the electrical appliance mounting plate 130 can be driven away from the support portion 122, making it easier to remove the electrical appliance mounting plate 130, or to bring the electrical appliance mounting plate 130 closer to the user, further facilitating maintenance.

[0061] In some embodiments, a column 122d is provided on the support portion 122. The column 122d is located in the slot 122b, and is located between the wall surface of the support portion 122 forming the installation space 120a and the supporting portion. The second spring 150 is sleeved on the column 122d. The second spring 150 is limited by setting the column 122d, so that the second spring 150 is stabilized in the slot 122b. At the same time, when the electrical installation piece 130 is pressed to disengage the limiting portion 122c, the column 122d can limit the stroke of the electrical installation piece 130, that is, it can provide feedback force to the user so that the user can confirm whether the electrical installation piece 130 has disengaged from the limiting portion 122c, which is convenient for the user to perform the next step of removing the electrical installation piece 130 from the slot 122b. The above description is only some preferred embodiments of the utility model 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 utility model is not limited to the technical solutions formed by the 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 and the technical features with similar functions disclosed in the embodiments of the present utility model (but not limited to) are replaced with each other to form a technical solution.
