Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet structure, and in particular to a plug-in switch module. Background Technology

[0002] Switches are commonly used components in distribution cabinets. In order to facilitate the installation and removal of switches, they are usually placed in drawers to form drawer-type switches. For drawer-type switches, the incoming and outgoing lines need to be isolated, and an installation position is required for the switch to be installed. Therefore, the current drawer-type switch modules have many parts, which leads to complex assembly, high labor consumption, and low efficiency.

[0003] Therefore, a new structure is needed for plug-in switch modules. Utility Model Content

[0004] The purpose of this utility model is to provide a plug-in switch module that addresses the above-mentioned problems, has a simple structure, is easy to assemble, and effectively improves assembly efficiency.

[0005] The technical solution adopted by this utility model is as follows: an insert-type switch module includes a drawer box, on which a switch component is installed as an installation position on the rear side panel of the drawer box. The switch component is located inside the drawer box, and the inlet end of the switch component is connected to an inlet busbar, and the outlet end of the switch component is connected to an outlet busbar. Both the inlet busbar and the outlet busbar are located outside the drawer box. A partition is fixedly connected to the outer side of the rear side panel, and the partition is located between the outlet busbar and the inlet busbar. The partition is provided with a connection hole.

[0006] Furthermore, the drawer box includes a bottom plate, on which a left guard plate, a right guard plate, a rear side plate and a front door are provided, and the front door is rotatably connected to the left guard plate / right guard plate.

[0007] Furthermore, a current transformer is connected to the outgoing line, and the current transformer is mounted on a mounting plate with mounting holes.

[0008] Furthermore, an insulating pad is provided between the mounting plate and the cable outlet.

[0009] Furthermore, a first fuse is also installed on the rear panel. The first fuse is connected in parallel to the incoming line bus, and the parallel circuit of the first fuse is used to connect the indicator light.

[0010] Furthermore, both the outgoing and incoming cable blocks have three terminals.

[0011] Furthermore, a second fuse is also installed on the rear panel. The second fuse is connected in parallel to the outgoing line, and the parallel circuit of the second fuse is used to connect to the control display.

[0012] Furthermore, heat dissipation holes are provided on the base plate.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The switch module disclosed in this utility model uses the rear panel of the drawer box as the mounting position, so that both the switch and the fuse can be installed on the rear panel without the need for a separate mounting position, reducing the required parts. At the same time, the partition is used to isolate the inlet and outlet cables. Compared with the previous structure of isolating the cable trays, the structure of this utility model is simpler, uses fewer parts, and does not cause installation inconvenience due to the presence of the partition plate that makes up the isolation box, thus effectively improving installation efficiency.

[0014] This utility model will be described by way of example and with reference to the accompanying drawings, wherein: Figure 1 This is a three-dimensional structural schematic diagram of the present invention; The markings in the diagram are: 11-rear side panel; 12-right guard plate; 13-front door; 14-bottom plate; 15-left guard plate; 16-heat dissipation hole; 2-switch; 3-inlet busbar; 4-partition plate; 41-connection hole; 5-outlet busbar; 6-mounting plate; 7-insulating pad; 8-second fuse; 9-first fuse. Detailed Implementation

[0015] In the description of this specification, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this specification and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this specification.

[0016] Furthermore, the use of terms such as "horizontal" and "vertical" in this specification does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0017] In the description of this specification, it should also be noted that, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” should be interpreted broadly. For example, a link can be a fixed link, a detachable link, or an integral link; it can be a mechanical link or an electrical link; it can be a direct link or an indirect link through an intermediate medium; it can be a connection within two components.

[0018] like Figure 1 As shown, an insert-type switch module includes a drawer box. A switch component 2 is installed on the rear side plate 11 of the drawer box as an installation position. The switch component 2 is located inside the drawer box, and the inlet end of the switch component 2 is connected to an inlet cable 3, and the outlet end of the switch component 2 is connected to an outlet cable 5. Both the inlet cable 3 and the outlet cable 5 are located outside the drawer box. A partition 4 is fixedly connected to the outer side of the rear side plate 11. The partition 4 is located between the outlet cable 5 and the inlet cable 3. A connection hole 41 is provided on the partition 4.

[0019] In this embodiment, the incoming line 3 is used to connect to the busbar of the main circuit, the outgoing line 5 is used to connect to the electrical appliances, and the switch 2 is a device used to control whether the electrical energy in the main circuit is supplied to the electrical appliances.

[0020] In this embodiment, the rear panel 11 of the drawer box is used as the installation position, so that both the switch 2 and the fuse can be installed on the rear panel 11 without the need for a separate installation position, reducing the required parts. At the same time, the partition 4 is used to isolate the inlet busbar 3 and the outlet busbar 5. Compared with the previous isolation box structure (the isolation box is a box that surrounds the inlet busbar 3 or the outlet busbar 5 circumferentially, but does not form an enclosure in the length direction of the inlet busbar 3 or the outlet busbar 5), the structure of this utility model is simpler, uses fewer parts, and does not cause installation inconvenience due to the installation space limitation of the outlet busbar 5 and the inlet busbar 3 caused by the presence of the plate that makes up the isolation box, effectively improving the installation efficiency.

[0021] It should be noted that the connection hole 41 on the partition 4 is used to connect to the cabinet of the power distribution cabinet, and is connected to the incoming and outgoing space of the power distribution cabinet to realize the isolation between the outgoing line 5 and the incoming line 3.

[0022] In one feasible implementation, the drawer box includes a bottom plate 14, on which a left guard plate 15, a right guard plate 12, a rear side plate 11, and a front door 13 are disposed. The front door 13 is rotatably connected to the left guard plate 15 / right guard plate 12. Typically, the front door 13 is provided with a locking mechanism for controlling the opening and closing of the front door 13. The locking mechanism is a conventional mechanism in the art and will not be described in detail here.

[0023] It should be noted that the drawer box design allows for modular installation of the switches. This means that the modular switch modules can be pre-assembled on the distribution cabinet without waiting for the pre-assembly of the distribution cabinet frame, which also facilitates the installation and removal of the switches.

[0024] In one feasible implementation, a current transformer is connected to the outgoing line 5. The current transformer is mounted on a mounting plate 6, which has mounting holes. The current transformer (not shown in the figure) is used to acquire current and detect the magnitude of the current present when the electrical appliance is in use. At the same time, the design of the mounting plate 6 and the mounting holes allows the current transformer to be fixed on the distribution cabinet.

[0025] In one feasible implementation, an insulating pad 7 is provided between the mounting plate 6 and the outgoing line 5 to prevent electrical energy on the outgoing line 5 from being transferred to the mounting plate 6 and then to the distribution cabinet, thereby reducing the possibility of electric shock to the operator.

[0026] In one feasible implementation, a first fuse 9 is also installed on the rear panel 11. The first fuse 9 is connected in parallel to the incoming line 3, and the parallel circuit of the first fuse 9 is used to connect an indicator light. When the indicator light is on, it is used to indicate whether the switch module is connected to the busbar of the main circuit. The first fuse 9 is set to prevent the indicator light from short-circuiting and causing excessive current, resulting in electric sparks and fire accidents.

[0027] In one feasible implementation, both the outgoing line bar 5 and the incoming line bar 3 have three terminals, namely L11, L12, and L13.

[0028] In one feasible implementation, a second fuse 8 is also installed on the rear panel 11. The second fuse 8 is connected in parallel to the outgoing line 5, and the parallel circuit of the second fuse 8 is used to connect the control display. The closing status of the switch 2 can be determined through the parallel circuit of the second fuse 8. The second fuse 8 is mainly used to protect the control display.

[0029] Specifically, there are three second fuses 8, which are connected between phase N and phase L11, phase N and phase L12, and phase N and phase L13, respectively. The control display determines whether the incoming and outgoing lines of phase L11, phase L12, and phase L13 in the switch 2 are effectively closed by whether the current of a certain second fuse 8 in the parallel circuit is obtained.

[0030] In one feasible implementation, the base plate 14 is provided with heat dissipation holes 16, which connect the interior of the drawer box with the interior space of the power distribution cabinet, so as to release the heat generated by the electrical components in the drawer box to the interior of the power distribution cabinet, and then exhaust it to the outside of the cabinet using the ventilation system of the power distribution cabinet, effectively avoiding the temperature inside the drawer box from getting too high, thereby avoiding fire.

[0031] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
