Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically to a modular ring network switchgear. Background Technology

[0002] A ring main unit is an electrical device consisting of a set of high-voltage switchgear housed in a steel plate metal cabinet or assembled into a modular ring main power supply unit. Its core components include load switches and fuses. It offers advantages such as simple structure, small size, low price, improved power supply parameters and performance, and enhanced power supply safety. It is widely used in substations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.

[0003] Ring main switchgear typically involves multiple units operating simultaneously due to the large number of control lines connected to it. When existing ring main switchgear is used in combination, it simply places the individual switchgear units together. In essence, each switchgear unit remains an independently movable entity. The lack of interconnection between these switchgear units makes it difficult to align them during arrangement and also makes them prone to scattering during use. Furthermore, the existing switchgear units have certain gaps between them, and the connections between them are not tight or secure enough, resulting in the switchgear units having room to wobble and affecting their operational stability.

[0007] The switch cabinet body has two rows of connection slots on its two side walls for connecting to the connecting components. The two rows of connection slots are symmetrically arranged. The connection slots include insertion holes and fixing slots. The fixing slots are opened on one side of the insertion holes.

[0008] The connecting assembly includes a mounting frame, two sets of connecting modules, and a driving module. The two sets of connecting modules are symmetrically arranged within the mounting frame and are slidably connected to the mounting frame. The driving module is installed in the middle of the mounting frame and is connected to the two sets of connecting modules. Each connecting module includes a movable column and several fixing mechanisms. The movable column is slidably installed within the mounting frame.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 The present invention provides the following technical solution:

[0021] A modular ring network switchgear includes several switchgear bodies 1 and several connecting components 2. The switchgear bodies 1 are fixedly connected to each other through the connecting components 2, and the switchgear bodies 1 can be connected and fixed together through connecting modules to form an integral structure.

[0022] The two side walls of the switch cabinet body 1 are provided with two rows of connection slots for connecting the connection component 2. The two rows of connection slots are symmetrically arranged. The connection slots include a socket 11 and a fixing slot 12. The fixing slot 12 is opened on one side of the socket 11. The two rows of connection slots are adapted to the connection component 2, so that the connection component 2 can be inserted into the connection slot.

[0023] The connecting component 2 includes a mounting frame, two sets of connecting modules and a drive module. The mounting frame is a rectangular structure composed of two guide rails 21 and two columns 22. The two guide rails 21 are located at the top and bottom respectively. The two connecting modules are installed between the two guide rails 21 and are symmetrically arranged, so that the drive module installed in the middle of the two columns 22 can drive the two connecting modules to move synchronously in opposite directions.

[0024] The connection module includes a movable column 23 and several fixing mechanisms. Sliders are provided at both ends of the movable column 23. The sliders are slidably installed on the two guide rails 21, so that the movable column 23 can be slidably installed in the mounting frame. Several fixing mechanisms are symmetrically arranged on both sides of the movable column 23. The fixing mechanism includes a fixing rod 24 and a limiting block 25. One end of the fixing rod 24 is fixedly connected to the movable column 23, and the other end of the fixing rod 24 is equipped with the limiting block 25. The limiting block 25 is adapted to the socket 11, and the fixing rod 24 is adapted to the fixing groove 12. When the limiting block 25 is inserted into the socket 11, the moving column 23 causes the fixing rod 24 to be locked into the fixing groove 12, thereby fixing the fixing mechanism together with the switch cabinet body 1.

[0025] Meanwhile, since the limiting block 25 has a spherical structure, once most of the limiting block 25 has entered the socket 11, when the movable column 23 drives the limiting block 25 to move, the limiting block 25 can push the switch cabinet body 1 toward the mounting frame, thereby reducing the gap between the mounting frame and the switch cabinet body 1.

[0026] The drive module includes a first screw 26, a second screw 27, and a rotating seat 28. One end of the first screw 26 is fixedly connected to one end of the second screw 27. The first screw 26 and the second screw 27 are rotatably mounted between two columns 22. One end of the second screw 27 is fixedly connected to the rotating seat 28. The rotating seat 28 is rotatably mounted at one of the columns 22. The end of the rotating seat 28 away from the second screw 27 passes through the mounting frame, and an inner slot 29 is provided at the end of the rotating seat 28. The inner slot 29 facilitates the user to rotate the rotating seat 28 with tools, thereby driving the two screws to rotate. The columns 22 of the two connecting modules are respectively threadedly connected to the first screw 26 and the second screw 27. Under the action of the two screws with opposite rotation directions, the two movable columns 23 can be driven to move synchronously in opposite directions.

[0027] The inner slot 29 is an internal hexagonal slot, which makes it easy for users to rotate the rotating base 28 with a hex wrench.

[0028] The specific implementation process is as follows:

[0029] When using this modular ring main unit switchgear, if multiple switchgear bodies 1 need to be spliced ​​and fixed, first place the connecting component 2 between two switchgear bodies 1, then push the switchgear body 1 so that the limiting block 25 of the connecting component 2 is inserted into the insertion hole 11 on the side of the switchgear body 1. Then, the user can use a tool to insert into the inner slot 29 of the rotating seat 28 and rotate the rotating seat 28. The rotation of the rotating seat 28 drives the first screw 26 and the second screw 27 to rotate. The first screw 26 and the second screw 27 respectively drive the two movable columns 23 to rotate on the two guides. The two movable columns 23 drive the fixed mechanisms to move together. Since the limiting block 25 of the fixed mechanism is a spherical structure, after most of it is inserted into the socket 11, under the guidance of the curved surface of the limiting block 25, the switch cabinet body 1 can be pushed towards the side of the mounting frame, so that the mounting frame fits against the side of the switch cabinet body 1. Then the fixing rod 24 of the fixing mechanism is inserted into the fixing groove 12 on the side of the switch cabinet body 1, thus completing the process of connecting and fixing the switch cabinet bodies 1 through the connecting components 2.

[0030] This modular ring main unit is connected to two adjacent switch bodies via a connecting component 2. This connection fixes the two switch bodies to both sides of the connecting component 2, thereby effectively improving the connection strength of the two switch bodies 1 and the neatness of their arrangement. Furthermore, the connecting component 2 allows the two switch bodies 1 to move closer together while sealing the gap between them, effectively improving the installation stability of the switch bodies 1.
